Welcome home. The slogan for the new E-Class can be taken literally. Just by getting in and closing the door, you find yourself in a totally different world. Noise, stress and the rush of everyday life remain locked outside, replaced by an overriding feeling of comfort and relaxation. Elegant forms, fine materials, attractive colours, comfortable seats and exquisitely designed details create an atmosphere in which you immediately feel at home.

One of the key aspects the Mercedes engineers focussed on to create this exceptional level of comfort was the new dimensional concept for the body and the interior, which differs from that of the outgoing model in many respects and thus allowed a new form of “spatial planning”. More space equals more comfort was the principle the product planners applied to design a body that is 16 millimetres longer, 10 millimetres lower and 32 millimetres wider than previously. Measured against the outgoing E-Class model, the wheelbase length has been increased by 20 millimetres to 2874 millimetres, which is a major factor behind the enhanced ride comfort and interior spaciousness. This is highlighted for example by the seat reference point, effectively the distance between the front and rear seats, which is crucial in determining the space in which the occupants are able to move: it measures 848 millimetres (outgoing model: 838 millimetres) and is therefore on a par with the level which, not so many years ago, was the standard for top-end luxury cars.

The occupants also benefit from the new dimensions of the E-Class when it comes to shoulder room and elbow width. Here the new Saloon impresses by offering up to 51 millimetres more (rear elbow width) than its predecessor, largely down to the wider body (+ 32 millimetres) and the wider track (front + 23 millimetres, rear + 49 millimetres). The effective headroom for the driver and front passenger has been increased by ten millimetres compared to the previous E-Class and now stands at 1048 millimetres; rear headroom is now 972 millimetres – an increase of eleven millimetres.

When it came to “spatial planning” of the boot, the Mercedes experts focussed on the everyday qualities drivers expect from an executive saloon. Hence the key criteria for the boot design were sufficient space for safely stowing four people’s luggage, practical variability when using the luggage compartment and excellent functionality for stowing large and small items. As well as being evident in the bare figures, the impressive end result can above all be seen when it comes to everyday practicality. Compared to the predecessor model, the length of the luggage compartment has been increased by 33 millimetres to 1177 millimetres, while the height has risen by 14 millimetres to 468 millimetres. The smallest luggage compartment width between the wheel arches has been extended by 24 millimetres and now measures 1000 millimetres. Furthermore, the boot opening, important for loading, has also been widened – by eleven millimetres to 500 millimetres.

In practice, these dimensions mean that there is now space for two jumbo suitcases side by side on the flat load-compartment floor or for four golf bags (including clubs). The overall boot capacity of 540 litres (as per the VDA measuring method) has been maintained despite the far more extensive basic equipment package for the new E-Class. There are 78 litres of stowage space available in the compartment beneath the luggage-compartment floor. And the optionally available folding rear-seat backrests allow Mercedes customers to increase the load-carrying capacity depending on the transport task in hand as well as producing a practically flat load bay. Standard-fit load-securing rings enable items of luggage to be secured in place.

For fast and easy stowage of smaller items, Mercedes-Benz equips the load compartment of the new E-Class with a robust bag hook and stowage nets on the load compartment side panelling. One new addition is the optional EASY-PACK load-compartment box, which attaches below the parcel shelf. From here, the box measuring around 530 millimetres in width can be pulled forwards and loaded with ease as it unfurls downwards and has variable settings. The box has a maximum capacity of 55 litres and can carry up to ten kilograms.

Wide choice of seats for business-class travel and wellbeing

Many aspects of the multicontour seat for the new E-Class have been further enhanced, prompting “Aktion Gesunder Rücken” (a German organisation that promotes back health) to award the seat its coveted seal of approval. Multicontour means that the occupants are able to adapt the contours of the seat to suit their anatomy or personal preferences. This is made possible by inflatable air chambers beneath the seat padding. A new method for adjusting the side bolsters allows the backrest width to be adjusted continuously variably by up to 45 millimetres on each side – in other words by a total of up to 90 millimetres.In the outgoing model, the maximum adjustment range was just 50 millimetres.

Another plus point of the new multicontour seat is the function for pneumatically adjusting the seat cushion length. The front air cushion increases the seat cushion length by up to 50 millimetres at the push of a button, allowing occupants to relax their legs and ensuring good blood circulation.

The likewise new active multicontour seat offers the same comfort functions and more than lives up to its name: fast piezo valves at the air chambers vary the inflation pressure and volume of the air chambers in the backrest side bolsters depending on the steering angle, lateral acceleration and road speed so as to offer the driver and the front passenger even better support.This active function relieves strain on the musculature and enhances well-being. Plus it improves safety as the fast piezo valves allow the active multicontour seats to be integrated into the PRE-SAFE®anticipatory occupant protection system (also see page 54): if the PRE-SAFE®control unit detects a critical driving situation, it activates the air chambers in the backrests almost instantaneously. These then envelope the seat occupants and provide them with support, limiting the dangerous whiplash movements of the upper body in the event of accident.

To ensure a relaxed and fatigue-free ride, the Mercedes engineers have developed another special feature, available in conjunction with the active multicontour seat, in the shape of a massage cushion in the backrest. It consists of seven air chambers that are inflated and deflated cyclically so that the passengers feel a pleasant rolling movement across their entire back area. This movement stimulates the musculature, boosts circulation and counteracts premature fatigue. The massage mat operates independently of the contour and lumbar settings.

Further features of the active multicontour seat include a luxury head restraint with moving side bolsters, which also incorporates crash-responsive NECK-PRO technology.

Filled seat piping for a new comfort experience right from the off

For the E-Class, the Mercedes experts have further enhanced the quality of a tried-and-trusted Mercedes concept: filled seat piping. This is a special form of upholstery in which an additional layer of foam is inserted under the fabric or leather cover. The soft upholstery makes the occupants feel comfortable and relaxed as soon as they take their seats in the car. The experts attach great importance to first impressions, in this case the impression a person has when sitting in a car seat for the first time. All in keeping with the “welcome home” motto.

The design of the filled seat piping depends on the design and equipment line: the base model and the AVANTGARDE line have seat covers with horizontal contours, while the ELEGANCE line features vertical contours, evoking memories of the equally famous and well-proven Mercedes seat design from the 1960s and 1970s. In each case, the manufacture of the filled seat piping is a complex process in terms of both the craftsmanship and the upholstery technology required. Only Mercedes-Benz uses this process

A newly developed moulded foam cushion effectively forms the seat’s lower comfort zone. In the centre area, the Mercedes engineers have increased the foam thickness by around twelve percent compared to the outgoing model. Coupled with the overall softer feel of the material in the seat centre, this design provides noticeably more comfort. In the area of the side bolsters, on the other hand, the foam is harder so as to enhance lateral support. In this way, the experts achieve an excellent pressure distribution, which helps relieve the strain on the spinal column and provides specifically targeted support for the pelvic area.

Mercedes seat developers have always attached great importance to the optimum distribution of the seat pressure as they view this as a key requirement for a high level of long-distance comfort. Seat pressure distribution is adjusted in eight different zones of the backrest and seat cushion, based on carefully acquired empirical values. The backrests of the front seats, for example, are divided into several pressure zones: whereas the foam is soft in the area of the cervical and lumbar curve, it is hard in the pelvic and shoulder areas, where optimum support is required. On the seat cushion, the pressure gets progressively lower between the hip and thigh areas – a key requirement for comfortable, fatigue-free car travel.

The foam upholstery used for the front seat cushions is housed in seat squabs with integral springing. Here a frame made partially from high-strength steel forms a solid base. Special tubular sections and energy-absorbing elements in the seat lining ensure that, in the event of a side impact, the seats are able to absorb high forces and transfer these to the side facing away from the impact.

Lumbar support as standard for healthy sitting

Because the human body is not designed to sit still for long periods, it needs support at specific points. One example is the lumbar lordosis – the area of the lower part of the spinal column where the backbone curves forwards. This inevitably leads to a hunched sitting posture – meaning that stress is exerted on one side

of the intervertebral discs. The lumbar lordosis therefore requires support when sitting. Standard equipment for the driver’s seat in the E-Class includes a lumbar support which provides ergonomic support for the spinal column in the lumbar region. If the Memory function is specified by the Mercedes customer, the two front seats are equipped with electropneumatically adjustable four-way lumbar supports including side-to-side adjustment as well as height and shape adjustment.

The front-seat backrests consist of steel frames with springing and foam elements whose contours, like the seat surfaces, provide even better lateral support. The backrest height has been increased by around 30 percent in the area at the top of the backrest to provide even better support for the shoulders.

Natural materials and active ventilation for a comfortable seat climate

When developing seats, the Mercedes experts do not merely think about classic comfort features such as springing and damping. Moreover, they look at the all-round wellbeing of the car occupants, including what is referred to as seat climate. The materials and structure of a Mercedes seat are designed to ensure wellbeing whatever the weather and temperature outside. In the case of the E‑Class seats, this is achieved thanks to the breathable material mix and the high-quality fabric or leather covers. The fabric covers contain 25 to 30 percent wool – a natural material which, unlike synthetic fibres, displays excellent electrostatic properties and, moreover, outstanding moisture absorption, which has a positive effect on the seat climate in high temperatures.

Even greater climate comfort is provided by the optionally available actively ventilated front seats: four ventilators in the seat cushion and in the backrest extract cool air from the floor area of the interior and distribute it evenly through a ventilation tissue beneath the seat surface. The mild airflow can prevent the car’s occupants from sweating, even when it is extremely hot outside.

Multiple adjustment options for the ideal sitting position

As before, the front seat height, cushion angle and backrest inclination can be adjusted electrically, while adjustment of the fore/aft position of the seat cushion is performed manually. Plus the seats in the new E-Class have the largest fore/aft adjustment range in this market segment: 277 millimetres. The individual seat position can be adjusted in very small 4.5-millimetre stages and is therefore almost continuously variable, whereas the backrest inclination is fully continuously variable. This means that very tall and very short drivers can adjust the seat so that all of the Saloon’s functions are within easy reach.

Adjustment ranges of the standard-specification front seats:

• Fore/aft adjustment277 millimetres
• Seat height59 millimetres
• Seat cushion angle4.5 degrees
• Head restraint height 85 millimetres; head restraint depth 45 millimetres
• Backrest angle110 degrees

The fully electrically adjustable seats for the driver and front passenger, which Mercedes-Benz supplies as optional extras, are even easier to use. In this case, the fore/aft position, seat cushion angle, head restraint, steering column and

exterior mirrors can be adjusted by electric motors in addition to the seat height and backrest angle. Three individual seat positions can be stored if the Memory function is specified. In this case, a touch of a button on the inner door lining is all it takes to move the seats, steering wheel and exterior mirrors to their programmed positions automatically.

Once the driver has removed the electronic ignition key from the new E-Class, the steering wheel can be moved upwards to make it even easier to get out of the car. The steering wheel then remains in this position until the ignition key is re-inserted, providing the driver with more legroom when getting back into the car as well.

Individual seats for the rear passengers

For the rear passengers in the new E-Class, Mercedes-Benz has developed a system comprising two individual seats offering an all-new comfort experience (optional). The soft foam upholstery used for the seat cushion and backrest features distinctive contours and makes travel on board the Saloon even more of a pleasure. These luxury rear seats feature leather upholstery, a heating function and their own head restraints as well as a centre console between them and a through-loading feature allowing longer items to be carried in the boot. The head restraints, adjustable for height and angle, have side bolsters which improve lateral support for the head, allowing the occupants to fully relax in any reclined position.

A spacious stowage compartment with two cup holders for various cup, can or bottle sizes is located beneath the leather-trimmed armrest. And the through-loading module can be equipped with an optional ski bag.

Climate control: THERMOTRONIC with three individual climate modes

Comfort is all about highly individual preferences. Which is why it is important for cars to offer their occupants a wide range of personalisation options. The new E-Class meets this requirement, not only in terms of suspension tuning and seat adjustability, but also when it comes to climate comfort.

The new E-Class marks the debut of a Mercedes-Benz-developed automatic climate control system which, as well as being able to set individual temperatures in three zones (for the driver, the front passenger and the rear passengers), additionally offers what are referred to as climate modes. This means that, if the optionally available THERMOTRONIC system is fitted, the car occupants can choose from “Diffuse”, “Medium” and “Focus” at the push of a button and thus adjust the air quantity and air distribution to their liking without having to leave the convenient automatic mode.

In “Diffuse” mode, for example, the THERMOTRONIC system operates with a low air speed and distributes the air over a wide area so that there are fewer draughts. This is the purpose of the automatically controlled, upwards inclined diffuse nozzle in the centre of the dashboard. In “Focus” mode, meanwhile, the air outlets in the centre area of the dashboard are used for the most part, meeting the need for a direct flow of a larger quantity of air.

Sophisticated sensors are another reason why the three-zone luxury automatic climate control system does full justice to its name. These ensure that the desired temperatures set by the occupants remain constant: even the standard-fit THERMATIC system features two sensors for the interior temperature, four sensors for measuring the temperature of the air flowing out of the air outlets and one sensor for recording the intensity and direction of the sun’s rays, while the THERMOTRONIC system for the new E-Class additionally includes a dew-point/moisture sensor and a pollutant sensor.

The dew-point sensor enables specifically targeted cooling and, if required, reheating of the inflowing air, meaning that the air conditioning operates even more economically. The pollutant sensor senses when the carbon monoxide and nitrogen oxide concentrations in the outside air are too high and, if the level of these pollutants increases suddenly, closes the air recirculation flap automatically.

Finally, the THERMOTRONIC system is equipped with a separate control panel at the rear of the centre console, allowing the rear passengers to select their ideal temperature and – if required – adjust the air quantity manually. This means they control the special booster in the centre console, which offers five speed settings and, therefore, ensures highly effective climate control in the rear of the car.

Another highlight of the THERMOTRONIC system is the residual heat function: pressing the “Rest” button heats or ventilates the interior for around 30 minutes when the engine is switched off.

The standard equipment package for the new E-Class includes THERMATIC two-zone automatic climate control. With this system on board, the driver and front passenger can set the desired temperature using the rocker switches on the elegant control panel in the lower section of the centre console. The OLED (organic light emitting diode) display indicates the programmed levels. If automatic mode is deactivated, the blower speed and air distribution can also be adjusted by rocker switch. The “ZONE” function is new: at the push of a button, the temperature settings are synchronised, and the level selected by the driver is transferred to the front-passenger side.

Heating output of a modern family house

The THERMATIC and THERMOTRONIC systems have received a boost in both heating and cooling output. The heating output has been increased by around ten percent to eleven kilowatts, equivalent to the power of the central heating system in a modern family house. In the diesel models and the four-cylinder models with direct petrol injection, a heat exchanger with six integral PTC heating elements (PTC = Positive Temperature Coefficient) is also activated when the outside temperature falls below a certain level in order to supplement the heater heat exchanger with an electrical output of around 1200 watts. The PTC heating element is required because, due to their high thermal efficiency, the sophisticated CDI and CGIengines are very economical on fuel and, therefore, give off much less heat to warm up the coolant than conventional engines when running under partial load.

An air-conditioning unit with an output of around 8.4 kilowatts – some five percent more than the unit used in the predecessor model – ensures rapid cooling of the interior. The air-conditioning compressor is continuously variable, allowing on-demand, i.e. economical, operation of the air conditioning. The control is provided by a solenoid valve which varies the swept volume of the air-conditioning compressor. In the E 200 CDI BlueEFFICIENCY model, Mercedes‑Benz uses an air-conditioning compressor which is disconnected from the engine’s belt drive automatically when no cooling power is required.

Fine-dust particulate filter fitted as standard

A large, hermetically sealed fine-dust combination filter, fitted as standard for the new E-Class, ensures that the air entering the interior is clean. It is 96 to 98 percent efficient at filtering out particles between five and ten micrometres in size and 100-percent efficient when it comes to removing ten-micrometre particles. Thanks to its activated-charcoal coating, the fine-dust combination filter can also filter out gaseous substances which are the cause of unpleasant odours. The filter is active on a permanent basis – even in air recirculation mode.

Up to ten electric motors and 18 air outlets for excellent climate comfort

The cleaned air flows to the centrally arranged evaporator, which cools and, therefore, also dries the air, depending on the temperature set by the car’s occupants. The temperature is then controlled with the help of the heater heat exchanger, which sets the desired outlet air temperatures. There are up to ten electric motors in total, whose job it is to control the cold and warm air flaps in the mixing zones as well as the air outlets, meaning that practically every air outlet can be regulated precisely as required. THERMATIC features 18 air outlets for effective and uniform ventilation of the interior, while THERMOTRONIC includes two additional rear outlets in the B-pillars.

As well as being more effective, the climate control systems for the new E-Class are also audibly quieter than before. Newly calculated cross-sectional areas for the air intake, the air ducts and the air-conditioning unit reduce the noise level at maximum cooling output by around three decibels (dB (A)), for example. In addition, the air ducting has been lined with acoustic absorption elements and/or sound-insulating foam.

Dashboard: technology and aesthetics in harmony

Attractive design, a pleasant feel and perfect ergonomics are the three main attributes of the dashboard and the centre console in the new E-Class – a harmonious blend that is one of the main factors behind the feeling of comfort and wellbeing experienced when riding on board the Mercedes Saloon.

As an option, the dashboard can be ordered with a two-tone design: while the upper section and the centre console are finished in a darker shade, the lighter contrasting colour used for the knee bolster, glove compartment lid and tunnel makes these areas really stand out. The surface of the dashboard is made from a polyurethane foam skin with additional padding. This sophisticated production process allows both small radii and precise edges, plus it ensures a pleasant feel. For particularly discerning motorists, Mercedes-Benz offers a dashboard trimmed in high-quality sheeting with fine topstitching for a perfect finishing touch. This item is part of the Exclusive package (optional extra), which also includes a fine Alcantara trim for the roof lining, sun visors and pillar mouldings.

The dashboard incorporates an illuminated glove compartment with a capacity of around 6.8 litres, which can be cooled by the automatic climate control system. A twelve-volt outlet and a socket for connecting an external audio device are also integrated. This is likewise the location of the optional media interface for connecting an MP3 player.

One of the main aims of the Mercedes engineers – to fuse elegant design with a pleasant feel – is reflected in the door panelling. They achieve this aim by combining high-quality materials such as fabric or leather and wood or aluminium with scratch-resistant plastic boasting a new grain-effect finish. The wide armrests on the door panelling are pleasingly soft to the touch and, therefore, exceptionally comfortable. Here the designers have integrated the control panel for the power windows, the locking/unlocking switch for the doors and the exterior mirrors so that it looks elegant and is also easy to reach and use. In addition to the expansive wood or aluminium trim strips at waistline height and the optical fibres for the ambient lighting in the ELEGANCE and AVANTGARDE models, the door panelling incorporates a second trim level, adding a further elegant touch beneath the armrests.

Centre console as command centre for the infotainment and automatic climate control systems

The centre console blends in harmoniously with the dashboard form and colour concept. This is where the controls for the infotainment system and the optionally available car phone are located, just below the air outlets. Beneath these, the buttons for the seat heating, seat ventilation, rear window blind, rear head restraints and other optional extras are demarcated by a discreet chrome strip. The lower section of the centre console houses the controls for the standard-fit automatic climate control system.

A special paint has been used to treat the visible areas of the buttons and controls, giving them a satiny shine and a soft finish. The experts call this “soft-touch paint”. Together with the sophisticated short-stroke buttons, which are easy to press and have very little travel, this paint helps ensure a pleasant yet precise feel. They buttons only need to be pressed once to activate or deactivate the function in question, and they always make a soft “clicking” sound to confirm that the desired function has been activated.

Every last detail designed for everyday practicality

A wealth of intelligently conceived details in the interior of the new E-Class highlight the fact that the Saloon has been developed with the customer and, therefore, everyday practicality in mind:

The front-passenger footwell incorporates a practical storage net suitable for holding an atlas or map. Directly above this is an adjustable plastic bottle holder.

In the ELEGANCE and AVANTGARDE models, two stowage boxes, each with a capacity of around 2.6 litres and suitable for carrying smaller items, are housed beneath the driver’s seat and front-passenger seat.

Additional coat hooks are built into the B-pillar trims.

As part of the Sun Protection package (optional extra), Mercedes-Benz supplies two-piece luxury sun visors for the driver and front passenger, an electrically operated rear window blind, guided on the C-pillars as in the S‑Class, and manually operated roller blinds for the insides of the rear side windows. They cover over 80 percent of the window area and, therefore, provide highly effective protection from the sun.

Proven concept for intuitive and reliable control

The aluminium controller on the centre console is one of the core elements of the tried-and-tested control and display concept which Mercedes-Benz first unveiled in the S-Class some years ago. It is based on the conviction that technology is only perfect if people can understand and master its use intuitively. To achieve this aim, the Mercedes experts have defined four basic principles that underpin their work:

1. Easy identification of the key control functions

2. Fast availability of the key spontaneous functions

3. Simple and intuitive control of the key functions

4. All the controls in the right place

Key features of the Mercedes control concept include special hotkey-type buttons which provide fast access to frequently used functions. This is why all the control and display elements that are necessary or important during a journey are located in the cockpit, i.e. in immediate proximity to the driver. These include the switches and stalks for the lights, windscreen wipers, indicators and cruise control (standard in models with automatic transmission).

Furthermore, in keeping with the “everything in the right place” logic, the switches and buttons for the power windows, central locking and exterior mirrors are where one would intuitively look for them: on the doors. In other words, the driver does not need to learn anything new and, when it comes to the controls too, feels at home immediately on board the new E-Class.

Multifunction steering wheel with twelve buttons

Alongside the controller on the centre console, the multifunction steering wheel is one of the main protagonists of the sophisticated control and display concept. Its buttons are linked to the central display in the instrument cluster and merely need to be tapped with a thumb to gain fast access to a wide range of information displayed right in front of the driver’s eyes. The driver uses the left-hand button in horizontal direction to mark one of the main menus on the central display and in vertical direction to select the desired submenu. Each selection or setting is accepted by pressing the “OK” button, while the “Return” button is used to return quickly to the next-highest menu level.

The buttons on the right-hand side of the multifunction steering wheel are used for adjusting the volume (vertical), activating the mute function (middle) and using the car phone (horizontal). Beneath these is an additional button for activating the LINGUATRONIC voice-operated control system.

Cockpit with five circular instruments featuring a high-quality chronometer-style design

There are five instruments in the cockpit to provide the driver with all the necessary information: speedometer (middle), rev counter (right), clock (right), coolant temperature gauge (far right) and fuel gauge (far left). Thanks to black-panel technology, the indicator and warning lights assigned to the various circular instruments are not visible during normal driving; the driver only sees these when the ignition is switched on or if a fault occurs.

In the centre of the speedometer is a two-section central display.

The lower section of the central display is used for displaying icons that provide information about the status of the driver assistance systems as well as digital readouts of the outside temperature, transmission gear and transmission mode

(if an automatic transmission is fitted). One of the new features is the fuel consumption and gearshift indicator (if the six-speed transmission is specified), which informs the driver of the current fuel consumption and at what point the next-highest gear should be selected in order to save fuel and reduce CO2 emissions (also see page 89).

Large colour display for the infotainment functions

In the centre of the dashboard – where it can be easily seen by the driver and the front passenger – a large colour display in 16:9 format provides information about all the infotainment system functions. There are two versions of this sophisticated AM-TFT(Active Matrix Thin Film Transistor) display available, depending on the equipment specified for the E-Class: a 5.8-inch version for the Audio 20 and Audio 50 APSdevices or a high-resolution 7.0-inch version for COMAND APS (also see page 82).

The controller on the centre console incorporates the main controls for the infotainment systems and allows fast and easy access to the devices’ clearly structured menus. This turn/push control can be moved in eight directions: turning the controller selects the main menu and submenus on the display, while pressing it activates or accepts the displayed function or setting. The “R” and “C” buttons in front of the controller are used to exit submenus quickly or delete entries.

As the infotainment control system has been designed redundantly, the car radio, CD/DVD changer, telephone and navigation system can be operated either using the controller or at the push of a button. This is the purpose of the function buttons on the centre console, which are positioned ergonomically so that the driver can reach them easily without having to take their eyes off the road.

Car radio, CD player and Bluetooth interface as standard

Information, communication, navigation, entertainment – these four aspects are now just as important a part of motoring as agile handling, outstanding comfort or powerful engines, for example. Motorists can no longer do without news, the telephone, navigation and music whilst driving. This is why Mercedes-Benz equips the new E-Class with sophisticated infotainment devices that deliver outstanding performance and, above all, are easy to use. These are called Audio 20 CD (standard equipment), Audio 50 APS and COMAND APS (optional extras).

All of the devices include speed-sensitive volume control, a keypad for entering telephone numbers and radio frequencies, a colour display in the centre of the dashboard and a Bluetooth interface to connect a mobile phone to the hands-free system wirelessly. Eight loudspeakers fitted as standard in the doors deliver superlative sound.

Features of the Audio 20 CDsystem, fitted as standard in the new E-Class, include a CD player (with MP3 capability), a dual tuner for FM/MW/LW/SW, automatic station search, RDS function (for FM reception) and a 4 x 20-watt amplifier.

The AUDIO 50 APS infotainment system is an all-in-one device featuring a combination of car radio, DVD player and Europe-wide DVD navigation system. The radio functions and the options for linking with other systems are the same as for the Audio 20 system. Mercedes customers who opt for the version with integral six-disc DVD changer also receive the LINGUATRONIC voice-operated control system.

COMAND APSwith even more functions

The Mercedes-Benz-developed COMAND APS multimedia system includes a DVD player for audio and video as well as a Europe-wide navigation system whose data are stored on a 40-gigabyte hard drive, allowing extremely fast access to the navigation data and, compared to DVD-based navigation, even faster route calculations. The high-resolution map appears on the 7.0-inch colour display in the centre of the dashboard and provides useful additional information. By way of example, the map shows the outlines of prominent buildings along the road to aid orientation.

In addition, COMAND APS includes a Music Register for around 1000 compressed music tracks in MP3, WMA or AAC format, which can be downloaded from PC memory cards. The system has a saved database (“Gracenote”), enabling it to recognise music tracks played from a CD, DVD or the Music Register and then display the title of the track and the artist on the display. Mercedes-Benz combines COMAND APS with LINGUATRONIC voice-operated control and a text-to-speech function as standard, allowing the driver to listen to route-specific traffic reports, SMS messages, address book entries or station names. New traffic reports relevant to the current route are read out automatically by the system.

Voice-operated control with whole-word voice input for navigation, telephone and radio

Mercedes-Benz, one of the inventors of modern voice-operated control systems, has continued to further develop the LINGUATRONIC system in recent years, meaning that the navigation system in the new E-Class can now be controlled based on the principle of whole-word voice input: the driver no longer needs to spell out the names of countries, towns or streets, but is able to speak them as whole words. It is just as easy to use the voice-operated control to select a radio station or an entry in the phone/address book: all available or stored names can be called up without the need for prior voice-input training.

As an option, Mercedes customers can combine the infotainment devices that feature in the E-Class with further systems offering even more information and entertainment:

The “Logic7” surround sound system developed by Mercedes-Benz in partnership with the audio specialist harman/kardon® provides three-dimensional audio enjoyment noticeable above all by a natural 360-degree music experience in all seats. It makes no difference if the music is played from a CD or a DVD or if the disc contains 5.1 surround or normal stereo recordings. The music signals are distributed by a 610-watt amplifier that controls 14 high-performance loudspeakers.

A media interface in the glove compartment can be used to connect an iPod, USB stick or other external audio devices to the infotainment system in the new E-Class. All that is required for this is a suitable cable from the Mercedes accessories range. The interface includes a control unit that links the external music memory to the Saloon’s on-board electronic and control systems. The advantage of this is that the titles of the tracks stored on the iPod can be shown on the colour display in the dashboard and in the instrument cluster, allowing them to be selected almost effortlessly using the controller and the buttons on the multifunction steering wheel. The battery in the audio device is charged for as long as the portable music memory is connected to the car via the media interface.

A separate DAB tuner (DAB= Digital Audio Broadcasting) and additional aerials (optional) allow passengers on board the new E-Class to receive digital radio stations in CD quality. The system switches to analogue reception automatically when the DAB signal is too weak.

A newly developed Rear Seat Entertainment System with a DVD player and two large colour displays (8.0-inch) in the rear of the front head restraints makes the ride even more entertaining for the rear passengers in the new E‑Class. The system also includes connection options for external audio or video devices and for the integration of a TV tuner. If COMAND APS is fitted, the DVD films and TV programmes (if the TV tuner is specified) played by the COMAND device can also be viewed by those passengers sitting in the rear seats.

BlueEFFICIENCY – the trademark for exceptionally economical and ecofriendly Mercedes passenger cars – is a package of measures compiled by development engineers across all disciplines, the main aims being to reduce weight, aerodynamic drag and rolling resistance, to further optimise the engine technology, and to make energy management even more efficient.

The Mercedes commitment to reducing fuel consumption and carbon-dioxide emissions targets actual driver usage profiles. As part of a large-scale field trial, the typical driving profiles of Mercedes customers were ascertained and combined in an in-house fuel-consumption test covering a total of almost two million kilometres. Hence the positive effects of the BlueEFFICIENCY concept are most noticeable during everyday use of the cars.

For the new E-Class, Mercedes-Benz has put together an extensive raft of measures, which is one of the key factors behind the reduction in fuel consumption of up to 23 percent. From the power steering to the tyres, from the fuel pump to the alternator, the development engineers scrutinised a wide range of components to determine if and how lightweight designs, new forms, more efficient control or enhanced functioning could be employed to save fuel. Although many of the individual measures only improved fuel economy by the odd percentage point or two, together they add up to a substantial saving.

Lower aerodynamic drag: fan shutter behind the radiator

The aerodynamic drag of a car rises by the square of the car’s speed and, at just 80 km/h, accounts for around 50 percent of all drag and rolling resistance. These figures show just how important aerodynamics are when it comes to fuel consumption and CO2 emissions – especially when driving at higher speeds. Reducing the drag coefficient (cd figure) by 0.01 only brings about a fuel saving of 0.04 litres per 100 kilometres in the New European Driving Cycle (NEDC) due to the low average speed of 33 km/h; however, in the real world – for example at a motorway speed of 130 km/h – this reduction in the cd figure equates to a fuel saving of up to 0.15 litres per 100 kilometres.

By performing computer calculations and meticulous work in the wind tunnel, the Mercedes engineers have succeeded in aerodynamically optimising the body of the new E-Class (also see page 49). The overall result is impressive to say the least: the cd figure for the Saloon is just 0.25 – significantly lower than the figures achieved by other saloons in this vehicle category.

One of the main reasons behind this outstandingly low drag coefficient is the new, electropneumatically controlled fan shutter. Its development is based on the knowledge that the air flowing through the radiator and the engine compartment accounts for up to ten percent of a car body’s total aerodynamic drag. The fan shutter allows the engine’s cooling air quantity to be limited in line with

requirements, thus saving fuel. In essence, this means that, when the engine is running under part load and requires relatively little cooling, the radiator grille is closed by a circular system of louvres located behind the radiator. For minimum cooling, the shutter allows just a small amount of residual air to enter the engine compartment, but opens completely when the sensors signal that more cooling air is required.

The fact that the area around the radiator is hermetically sealed ensures that the fan shutter works extremely effectively, allowing precise control of the air flowing into the engine compartment.

When the fan shutter is closed, the cd figure falls by 0.013, which is equivalent to a fuel saving of up to 0.2 litres per 100 kilometres when travelling at the motorway speed of 130 km/h. The fan shutter is fitted as standard on the four-cylinder models and on the E 350 CGI BlueEFFICIENCY model.

Energy management: intelligent detail solutions beneath the bonnet

The most important aspect when trying to save fuel and reduce CO2 emissions is to avoid unnecessary energy losses – both internal losses caused by friction in the powertrain and losses due to drag and rolling resistance.

By way of example, the use of a turbocharger in place of the previous mechanical supercharger in the new models with direct petrol injection allows more efficient energy management, since the mechanical drive power from the belt drive required to operate the supercharger is no longer needed. The biggest plus point in favour of the new four-cylinder engines is the homogeneously operated direct injection system, which brings about a major increase in thermodynamic efficiency compared to the previous port injection system. The fuel vaporising in the cylinders lowers the temperature in the combustion chambers, thereby reducing the engine’s tendency to knock and allowing higher compression. The engine developers have succeeded in cutting fuel consumption further still by incorporating an intelligent thermal management system which prevents coolant from being pumped through the cylinders when the engine is cold, meaning that the combustion chambers heat up more quickly.

Part of the BlueEFFICIENCY concept involved optimising the automatic transmissions for the new E-Class: the newly developed converter for the five-speed automatic transmission reduces hydraulic losses and, therefore, uses up less fuel. For the 7G-TRONIC seven-speed automatic transmission in the E 350 CDI BlueEFFICIENCY model, Mercedes-Benz has developed a standstill decoupling function: when the car is stationary at traffic lights or in a traffic jam, for example, the transmission switches to “N” position so as to reduce the engine load.

The standard-fit power steering system is based on an intelligent solution designed to prevent energy losses and, therefore, cut fuel consumption. Unlike conventional steering systems, in which the power steering pumps operate at full power on a permanent basis, the power steering pump in the new E-Class features an additional valve for on-demand control. This means that, when the driver does not require steering assistance – when driving straight ahead, for example – an electronic control unit minimises the operating power of the power steering pump. The advantage of this system is that the engine does not need to provide energy (or only needs to supply very little energy) to drive the pump. However, the delivery rate of the power steering pump is increased again spontaneously when the driver moves the steering wheel. In this instance too, the system operates on-demand, adjusting itself in line with the current steering angle, engine speed and vehicle speed.

The same basic principle applies to the automatic climate control system in the new E 200 CDI BlueEFFICIENCY model: if the air conditioning system does not require any cooling power, the air-conditioning compressor is disengaged from the engine’s belt drive.

In order to ensure on-demand energy management, Mercedes-Benz uses controlled fuel pumps in the petrol engines for the E-Class (the diesel engines will also incorporate this feature from autumn 2009 onwards). In this setup, the engine control unit only calls for the maximum pump output during full-load operation. In other driving situations, the pump adapts the delivery volume and pressure in line with requirements, resulting in a fuel saving of 0.15 litres per 100 kilometres (NEDC).

Energy recuperation: power from braking energy

Each time the car is braked, kinetic energy is converted into heat and therefore goes to waste. This is why the E-Class incorporates efficient alternator management. This means that, whenever the engine is coasting and whenever the vehicle is braked, the voltage level in the vehicle electrical system is increased and the battery is charged. This increased alternator load assists the driver with braking and also helps to recuperate part of the braking energy, which is converted into electrical energy. This is why the experts refer to recuperation. Conversely, the alternator switches to no-load operation in certain situations – for example when accelerating or when the battery charge level is high – thus relieving the strain on the drive system. This process saves fuel to the tune of around 0.1 litres per 100 kilometres on paper (NEDC) and up to 0.2 litres per 100 kilometres when on the road in city traffic, where coasting and braking are more frequent than in the NEDC test cycle.

Energy saving: engine switched off at traffic lights and tips for economical driving displayed in the cockpit

To reduce fuel consumption when the engine is idling, Mercedes-Benz has developed the ECO start/stop function for the new E 200 CGIBlueEFFICIENCY model: the direct-injection petrol engine is switched off as soon as the driver applies the brakes, shifts the manual transmission to neutral and releases the clutch; however, the engine is restarted as soon as the driver depresses the clutch. What’s more, thanks to direct-start technology, the Mercedes-Benz-developed system operates spontaneously and with little noise: fuel is injected directly and ignited during the piston’s compression stroke, allowing the engine to be started with only very little assistance from the starter. The E 200 CGI BlueEFFICIENCY model is only started conventionally – with longer starter assistance and fuel injection during the suction stroke – in operating ranges that do not allow an automatic start function to be used, for example when the engine is cold.

The tyres also help to minimise fuel consumption. The E-Class is fitted with newly developed tyres whose rolling resistance has been reduced by up to 17 percent without impairing their outstanding handling and braking characteristics.

Finally, drivers can also help to save fuel, aided in the new E-Class by a display in the centre of the speedometer, which indicates the current fuel consumption – in litres per 100 kilometres. Drivers are therefore aware of whether they are driving fuel-efficiently or not. In addition to showing this information, the display also advises the driver when to change up a gear. Mercedes-Benz “ECO driver training” courses have shown that adopting an economical and energy-efficient driving style alone can cut fuel consumption by up to 15 percent on average.

“Less is more”. This slogan certainly proves true when looking under the bonnet of the E‑Class. That’s because the newly developed and modified four-cylinder powerplants have a higher output than the previous six-cylinder units, despite the reduction in displacement. Plus they return impressive fuel-consumption figures that were previously only achievable in the compact-car class. The Mercedes strategy is to use turbocharged engines with lower displacement in place of high-displacement, non-turbocharged engines. Key benefits of the concept include lighter weight, reduced internal friction and a more economical fuel-consumption map.

The new four-cylinder diesel engine in the E 250 CDI BlueEFFICIENCY model, for example, is proof that the plans have worked out successfully: with an output of 150 kW/204 hp, a peak torque of 500 Nm and a displacement of 2.1 litres, it develops around seven percent more power and delivers 25 percent more torque than the previous V6 diesel engine with a displacement of three litres whilst consuming around 23 percent less fuel: just 5.3 litres per 100 kilometres (NEDC combined figure), making it far more fuel-efficient than comparable saloons in this performance class. The CO2 emissions figure for the new four-cylinder diesel models is 139 grams per kilometre – up to 24 percent lower than the figures achieved by the previous CDI models.

In the case of the petrol models too, “more power and more driving pleasure with even lower fuel consumption” proves to be the perfect formula: the E 200 CGI BlueEFFICIENCYmodel with direct petrol injection has a displacement of 1.8 litres and an output of 135 kW/184 hp yet consumes a mere 6.8 litres of premium unleaded petrol per 100 kilometres (provisional NEDC combined figure). Plus the CO2 emissions figures for the four-cylinder petrol models are more than a fifth lower than those for the outgoing models.

As with carbon dioxide emissions, the engines for the new E-Class have also taken a further major step towards the future when it comes to exhaust gas emissions: all of the powerplants meet the requirements of the EU 5 standard, whose limits are up to 80 percent more stringent than those in previous standards. And with the new E 350 BlueTEC, Mercedes-Benz offers the world’s cleanest diesel, undercutting the limits of the EU 6 standard, which is not even due to come into force until 2014.

Diesel engines: newly developed four-cylinder model with a choice of three power outputs

The newly developed diesel engine extends the range of four-cylinder CDI units for the E-Class to three. These engines span the power output range from 100 kW/136 hp to 150 kW/204 hp; fuel consumption and CO2 emissions in all the new four-cylinder diesel engines have been reduced to just 5.3 litres per 100 kilometres and 139 grams per kilometre respectively (NEDC combined fuel consumption).

The technical advances made by the Mercedes-Benz engine designers responsible for this new four-cylinder diesel unit can also be seen in the performance figures: the most powerful variant, with an output of 150 kW/204 hp, outperforms its predecessor by 20 percent yet has the same displacement. Plus the peak torque has been increased by 25 percent from 400 to 500 N m. When it comes to speci fic output too, the powerplant posts a new record: 70 kW/95 hp and 233 Nm per litre of displacement.

The new engines are characterised by high output, agile response and exceptional pulling power. Plus they are exceptionally refined for four-cylinder units. Then there is the highly impressive agility, reflected in the performance figures, for example: the E 250 CDI BlueEFFICIENCY accelerates from zero to 100 km/h in just 8.2 seconds, while the sprint from 80 to 120 km/h takes the Saloon a mere 9.7 seconds. The E 220 CDI BlueEFFICIENCY developing 125 kW/170 PS takes 9.1 seconds to reach 100 km/h from a standing start and accelerates from 80 to 120 km/h in 11.3 seconds, while the E 200 CDI BlueEFFICIENCY completes the burst from zero to 100 km/h in 10.7 seconds and from 80 to 120 km/h in 13.2 seconds.

A wealth of innovative technologies has been implemented to enable the four-cylinder diesel engines to achieve their exceptional power and torque characteristics, economy, emissions performance and refinement, including new developments that do not currently feature in any other standard-production diesel engine for passenger cars.

Fourth-generation common-rail technology with piezo injectors

This series of four-cylinder engines sees Mercedes-Benz introducing fourth-generation common-rail direct injection into series production. One of its hallmarks is a 400-bar increase in the maximum rail pressure, which now stands at 2000 bar for the E 220 CDI BlueEFFICIENCY and the E 250 CDIBlueEFFICIENCY models. This increased pressure potential was a key factor in raising the engine output to up to 150 kW/204 hp and the peak torque to 500 Nm whilst also achieving a significant cut in untreated emissions.

Newly developed piezo injectors are key components in the latest CDIgeneration. They use their piezoceramic properties to change their crystal structure – and therefore their thickness – in a matter of nanoseconds when electrical voltage is applied. The injectors are equipped with a stack of thin piezoceramic layers (called the “piezo stack”) to enable them to achieve a sufficient overall lift from the very small lift per layer. In contrast to the systems commonly used to date, this lift activates the nozzle needle directly, so that the fuel injection can be adjusted more precisely in line with the current load and engine-speed situation – for example by means of precise multiple injections, which have a favourable effect on emissions, fuel consumption and combustion noise. What’s more, the engine is far quieter when idling than its predecessor.

Another key factor behind the impressive output and fuel consumption at full load with respect to emissions is the maximum ignition pressure. And, with 200 bar, the new four-cylinder diesel unit from Mercedes-Benz is among the leading contenders in the field of passenger-car diesel engines.

Impressive torque yield thanks to two-stage turbocharging

The new diesel engine in the E 220 CDI BlueEFFICIENCY and E 250 CDI BlueEFFICIENCY models marks the debut of two-stage turbocharging in a standard-production diesel engine for passenger cars at Mercedes-Benz. The aim is to achieve further advantages compared to a single-stage turbocharger, for example a further improvement in start-up performance and peak output. A single-stage turbocharger with variable nozzle turbines is used in the E 200 CDIBlueEFFICIENCY model. The lower engine power allows a smaller turbocharger to be used and, therefore, ensures likewise excellent start-up performance.

The compact module for the new two-stage turbocharger consists of a small high-pressure (HP) turbocharger and a large low-pressure (LP) turbocharger. These are connected in series, and each has a turbine and a compressor driven by this turbine. The HP turbine is located directly at the exhaust manifold and initially allows exhaust gas to flow through it; it then rotates at up to 215,000 revolutions per minute. The HP turbine housing features an integral bypass duct, which can be opened or closed by means of a charge-pressure control flap triggered by a vacuum cell. If the flap is closed, the whole exhaust stream flows through the HP turbine, meaning that the exhaust-gas energy is available solely for the HP turbine drive. This means that the optimum charge pressure can be built up at low engine revs.

As the engine speed increases, the charge-pressure control flap opens, primarily to prevent the HP turbocharger from becoming overloaded. A portion of the exhaust stream then flows through the bypass duct to relieve the HP section. Downstream of the HP turbine, the two exhaust gas streams join up again, and any remaining exhaust gas energy drives the HP turbine at a maximum speed of up to 185,000 revolutions per minute.To protect against overloading, the LP turbine is also equipped with a bypass, which is opened or closed by means of a wastegate. Once the engine reaches medium revs, the HP turbine’s charge-pressure control flap is opened so wide that the HP turbine ceases to perform any appreciable work. This allows the full exhaust gas energy to be directed with low losses into the LP turbine, which then does all of the turbine work.

The two compressors are likewise connected in series and are in addition connected to a bypass duct. The combustion air from the air cleaner first flows through the low-pressure compressor, where it is compressed as a function of the LP turbine’s operating energy input. This pre-compressed air then passes into the high-pressure compressor, which is coupled to the HP turbine, where it undergoes further compression – the result is a genuine two-stage turbocharging process.

The key benefit of this sophisticated, on-demand control of the combustion air supply by means of two turbochargers is the improved cylinder charging and, consequently, a high torque even at low revs. What’s more, fuel consumption is reduced. During normal operation, the advantages of this concept can be seen in the harmoni ous driving characteristics without turbo lag, a good torque curve across the entire engine speed range, spontaneous throttle response and noticeably improved performance.

As a logical addition to the turbocharger system, Mercedes-Benz installs a larger intercooler than the one seen in the previous models, which reduces the temperature of the compressed and heated air by around 140 degrees Celsius so that a larger volume of air can enter the combustion chambers.

Lower NOx emissions thanks to cooled exhaust gas recirculation

The newly developed EGRvalve works like a rotary disc valve and ensures precise control of the fresh air and recirculated exhaust gas. So as to optimise the quantity of exhaust gas recirculated and thereby achieve high recirculation rates, the exhaust gases are cooled down as required in a highly efficient heat exchanger with a large cross-sectional area. Together with the HFM (hot-film air-mass sensor) module integrated in the fresh-air ducting, which provides the engine control unit with precise information about the current fresh-air mass, this setup brings about a significant reduction in nitrogen oxide emissions.

The combustion air subsequently flows into the charge-air distributor module, which supplies air to each cylinder in a uniform manner. Built into the distributor module is an electrically controlled intake port shutoff, which allows the cross-sectional area of each cylinder’s intake port to be smoothly reduced in size. This alters the swirl of the combustion air in such a way as to ensure that the charge movement in the cylinders is set for optimum combustion and exhaust emissions across the full range of engine loads and speeds.

The advantages of a rear-mounted camshaft drive

Another of the highlights of the new four-cylinder diesel engine is the rear-mounted camshaft drive, which allows statutory pedestrian protection requirements to be met when the engine is installed longitudinally and the bonnet rises from front to rear. The valve timing mechanism is another new development and reduces friction at the 16 intake and exhaust valves, which are controlled by one overhead intake camshaft and one overhead exhaust camshaft acting via cam followers featuring hydraulic valve clearance compensation. The camshaft, Lanchester balancer and the ancillary assemblies are driven by a combination of gearwheels and just a short drive chain.

The switchable water pump, another highlight of the new Mercedes diesel engine, helps to quickly heat up the combustion chambers and the friction partners as well as reducing fuel consumption and untreated emissions. The pistons are cooled by an oil pump with a central control valve for all four piston-cooling sprayer units with large oil-spray nozzles. It creates identical, thermal boundary conditions for all cylinders. The generous dimensions ensure optimum piston cooling, even at full load, and make for a long service life. What’s more, the controlled oil pump reduces the oil flow rate and, therefore, consumption.

Six-cylinder CDI engine: higher output and torque but lower fuel consumption

In a similar vein, the V6 diesel engine for the new E-Class is one of the most sophisticated compression-ignition units on the world market. It offers substantially greater output, comfort and driving enjoyment than other engines thanks to the immense torque of 540 Nm alone, which is available between 1600 and 2400 rpm, ensuring outstanding agility when accelerating from rest and exemplary flexibility when accelerating in any gear. To put this into figures, the E 350 CDI BlueEFFICIENCY model (170 kW/231 hp) accelerates from 0 to 100 km/h in 6.9 seconds and from 80 to 120 km/h in 5.1 seconds.

Despite the higher output and torque, fuel consumption has been reduced by 0.5 litres to 6.8 litres per 100 kilometres (NEDC combined figure), equivalent to 179 grams of CO2 per kilometre. The 7G-TRONIC seven-speed automatic transmission is specified as standard for the E 350 CDI BlueEFFICIENCY model.

The Mercedes engineers have gone to great lengths to optimise the technology at the heart of the V6 diesel engine, reducing the compression from 17.7 to 15.5, enhancing the turbocharger with a more efficient EGR cooling zone, switchable bypass duct, ceramic glow system, modified injection nozzles and optimised air ducting.

E 350 BlueTEC meets the requirements of the EU6 emission standard

BlueTEC is a key concept for the future of the diesel engine. Thanks to the highly efficient emission control system developed by Mercedes-Benz, the compression-ignition models meet the strictest of emission requirements, making them the world’s cleanest diesel cars. This technology will be available for the E-Class in the new E 350 BlueTEC model with V6 diesel engine from autumn 2009 onwards. In this model variant, the powerplant has an output of 155 kW/211 hp and provides its maximum torque of 540 Nm from 1600 rpm. Fuel consumption in the E 350 BlueTEC model with seven-speed automatic transmission is 7.0 litres per 100 kilometres (provisional NEDC combined figure), while the CO2 emissions figure is 183 grams per kilometre.

For its installation in the BlueTEC model, the V6 engine has been modified in detail, among other things to further reduce in-engine untreated emissions and to meet the statutory requirements with respect to on-board diagnostics (OBD). The emission control system features a close-coupled oxidation catalytic converter and a diesel particulate filter which is located in the firewall area. Regeneration times are reduced as a result.

At the heart of the BlueTEC system are two SCR catalytic converters (SCR= Selective Catalytic Reduction) and an upstream “AdBlue®” injector. “AdBlue®” is an aqueous urea solution which converts the nitrogen oxides (NOx) in the SCRcatalytic converters into harmless nitrogen through a process of reduction. The complex exhaust gas aftertreatment process is monitored and diagnosed by several sensors, including a differential pressure sensor and an oxygen sensor as well as NOX and temperature sensors.

For the “AdBlue®” additive, the E 350 BlueTEC is installed with an additional 25‑litre tank equipped with a diaphragm pump, valve, pressure and temperature sensor, and an electric heater. The latter prevents the 33-percent urea solution from freezing at low temperatures. The tank is refilled as part of the scheduled maintenance programme.

Petrol engines: new four-cylinder units with direct injection

CGI appears at the end of the model designation of the four- and six-cylinder engines for the new E-Class, signifying that Mercedes-Benz uses direct petrol injection for these powerplants – a technology which allows further advances when it comes to reducing petrol consumption.

Compared to conventional port injection, direct fuel injection allows higher compression and, therefore, improved thermodynamic efficiency, saving motorists money at the pump: the new four-cylinder direct-injection powerplants for the E‑Class consume up to 21 percent less fuel than the comparable engines installed in the outgoing model. In the E 250 CGI BlueEFFICIENCY model (150 kW/ 204 hp), Mercedes-Benz has replaced the previous V6 2.5-litre engine with a four-cylinder 1.8-litre unit yet still manages to increase torque by over 26 percent. This result reveals a further Mercedes strategy for the future: the use of turbochargers in small-displacement engines.

The new four-cylinder petrol engines combine excellent economy with outstanding power delivery and agility, as highlighted by the performance figures for the E 200 CGI BlueEFFICIENCY and E 250 CGI BlueEFFICIENCY models:

E 200 CGI BlueEFFICIENCY:

0 to 100 km/h: 8.7 seconds

80 to 120 km/h: 13.9 seconds

E 250 CGI BlueEFFICIENCY:

0 to 100 km/h: 7.7 seconds

80 to 120 km/h: 6.0 seconds (in 3rd gear)

Mercedes-Benz equips the E 250 CGI BlueEFFICIENCY model with a five-speed automatic transmission, while the E 200 CGI BlueEFFICIENCY model features a six-speed manual transmission and the ECO start/stop function (also see page 90), which shuts off the engine automatically when it is idling, thus making a significant contribution towards saving fuel.

Variable camshaft adjustment and intelligent thermal management

The four-cylinder engines are made almost entirely of aluminium: the crankcase is made of cast aluminium, while a special, high-strength aluminium alloy is used for the cylinder head. Two forged overhead camshafts with variable adjustment are used to control the 16 valves. A vane-type adjuster with integrated control valve allows fast and smooth adjustment of the timing, ensuring that it is always at the optimum setting. This setup has two advantages: firstly, the variable camshaft adjustment enables a high torque yield even at low revs; secondly, this technology allows high specific outputs. The valves are controlled by means of cam followers and feature maintenance-free, hydraulic valve clearance compensation.

The Mercedes engineers have paid special attention to the engine’s warm-up governor because it affects fuel consumption. This is why the new direct-injection petrol model features an electronically controlled thermostat to ensure that circulation of the coolant is stopped when the engine is cold. This setup allows the engine oil to heat up quickly and, therefore, minimises in-engine friction. This intelligent thermal management system is logic-controlled. In other words, it is based on driving style, ambient temperatures and other parameters.

The turbocharger module is welded to the exhaust manifold on the engine’s exhaust side and features a wastegate valve and a deceleration air function for controlling the pressure characteristics. There were very good reasons for using a turbocharger in place of the previously installed mechanical supercharger – not least the higher efficiency as the engine does not need to provide the extra drive power required for the mechanical supercharger. What’s more, the turbocharger takes up far less space than the supercharger, weighs around four kilograms lighter and, in addition, also offers better noise and vibration characteristics. The Mercedes engineers brought about a noticeable improvement in the turbocharger’s bottom-end response by incorporating newly developed turbine geometry and a cylinder-flushing process.

Injection pressure of up to 140 bar and new multi-hole injectors

Mercedes-Benz has a long tradition in the field of direct petrol injection. As early as the mid-1950s, the Stuttgartmanufacturer unveiled this technology in the 300 SL, the legendary “Gullwing” model. This classic sports car was the first series-produced automobile to feature a four-stroke engine with direct injection – a sensational development that boosted the six-cylinder powerpack’s output significantly.

In the direct-injection system, the air and fuel are not mixed until they reach the combustion chambers. With the help of an injector, the fuel is injected into the cylinders at an angle of 30 degrees and, depending on the engine operating characteristics, at a pressure of up to 140 bar. Here the fuel droplets and the air particles form a mixture which is guided to the spark plugs via specially shaped recesses in the pistons. By way of comparison, the fuel pressure in a four-cylinder engine incorporating conventional injection technology is approximately 3.8 bar.

In order to ensure optimum swirl in the mixture, thus making combustion fast and as complete as possible, the CGI engines have intake ports with specially calculated flow characteristics. An adjustable swirl flap is also used so as to produce high turbulence in certain operating ranges and thus improve the combustion process. The high-pressure fuel pump is driven by the intake camshaft, while a quantity control valve integrated in the pump module ensures on-demand metering of the fuel supply. A pressure regulator with its own sensor, monitored by the engine control unit, controls the pressure in the fuel line (rail), which is directly connected to the multi-hole solenoid injectors. The four-cylinder direct-injection units operate in the homogeneous range, in other words with a stoichiometric air-to-fuel ratio of 14.6 : 1 (Lambda = 1), which is important for emission control by means of three-way catalytic converter. The new four-cylinder direct-injection engines meet the requirements of the EU5 emission standard.

Balancer in the crankcase and controlled oil pump

In addition to exemplary power delivery, low fuel consumption and low exhaust emissions, the new Mercedes four-cylinder engines have a further advantage, namely outstanding refinement thanks in no small part to the newly developed Lanchester balancer: two forged shafts supported in three bearings, which are arranged below the crank mechanism and counter-rotate at twice the crankshaft speed. In so doing, they compensate for the inertia forces which are caused by the motion of the pistons, for example, and can lead to irritating vibrations. The aluminium housing that contains the bearing-mounted balancer shafts is located in the oil sump, where it is bolted to the crankcase from below. The crankcase also contains the controlled engine oil pump, which is driven by one of the two shafts by means of a gear pair.

CGI six-cylinder engine with spray-guided direct petrol injection

The E 350 CGIBlueEFFICIENCY model is equipped with the world’s first petrol engine to feature spray-guided direct injection. The six-cylinder powerplant develops 215 kW/292 hp and provides a peak torque of 365 Nm from 3000 rpm. Thanks to the state-of-the-art engine technology, which Mercedes-Benz has modified right down to the last detail, fuel consumption is reduced to between 8.5 and 8.8 litres per 100 kilometres (NEDC combined figure), which is 0.5 litres per 100 kilometres less than the figure achieved by the outgoing model. These exemplary performance and fuel-consumption figures are achieved using cost-efficient premium unleaded petrol (RON 95).

What’s more, the highly economical and environmentally compatible CGIpowerplant provides a unique driving experience: it takes the E 350 CGIBlueEFFICIENCY model just 6.3 seconds to accelerate from 0 to 100 km/h and a mere 4.2 seconds to complete the sprint from 80 to 120 km/h (in third gear).

Stratified-charge mode, even at higher engine speeds, thanks to multiple injection

Mercedes-Benz was the first car manufacturer to introduce spray-guided direct petrol injection into series production in 2006. Thanks to higher thermodynamic efficiency, this technology allows better use of the fuel and, therefore, lower fuel consumption and lower exhaust gas emissions. The key benefit of the six-cylinder engine is delivered in stratified-charge mode, when the powerplant operates with a high degree of excess air and, therefore, extremely fuel-efficiently. This advantageous “lean-burn operation” is now also possible when the Mercedes direct-injection unit is running in higher engine speed and load ranges because the combustion chambers are supplied with fuel several times in succession within a fraction of a second in every combustion cycle, thus improving mixture formation, combustion and consumption.

Fast and precise piezo injectors are among the key components of the second-generation direct petrol injection system. They open their nozzle points outwards, forming an annular gap that is mere micrometres in size, shaping the jet of fuel and ensuring its even, hollow-cone-shaped dispersion. Thanks to their ability to switch within milliseconds, the piezo injectors also allow the multiple injection that is also of benefit for lean-burn operation, thus playing a crucial role in achieving the engine’s exemplary consumption figures. A high-pressure pump with downstream distributor and pressure valve supplies the fuel and ensures on-demand flow control. With a level of up to 200 bar, the system’s fuel pressure is several times higher than that in a conventional port injection system.

The combustion process with several injections in succession per combustion cycle developed by Mercedes engineers also enhances the refinement and emission characteristics of the V6 engine. Tests show that untreated emissions (hydrocarbons) are reduced by more than half in the warm-up phase. Plus the specifically targeted injection and combustion control allows higher temperatures in the exhaust manifold, ensuring faster heating of the catalytic converters.

Emissions are controlled by two close-coupled three-way catalytic converters with linear lambda control, which are activated immediately after a cold start. Mercedes-Benz reduces nitrogen-oxide emissions by means of two-pipe electrically controlled exhaust gas recirculation, which directs up to 40 percent of the exhaust gases back into the cylinders, depending on the engine’s operation, and by means of two NOx storage catalytic converters on the underbody. During lean-burn operation, these catalytic converters absorb the nitrogen oxides and re-release them in short regeneration phases so that they react chemically to form harmless nitrogen.

Four valves per cylinder, variable intake and exhaust camshaft adjustment, a two-stage intake manifold, a balancer shaft and intelligent thermal management are further highlights of the V6 engine with direct injection. The crankcase and cylinder head are made of aluminium; the cylinders are equipped with liners that have a low-friction aluminium-silicon coating.

Precision-modified eight-cylinder engine

The eight-cylinder unit in the E 500 model – the flagship powerplant in the new generation of Mercedes-Benz V engines – incorporates an extensive technology package to create a blend of high output and torque yield with exemplary refinement and effortlessly superior agility. The extent of the powerplant’s capability is highlighted by the performance figures for the new top-of-the-range E-Class model, which is equipped with the 7G-TRONIC 7-speed automatic transmission as standard:

0 to 100 km/h: 5.3 seconds

80 to 120 km/h: 3.6 seconds (in 3rd gear)

By incorporating an intelligent valve-timing concept, the Mercedes engineers achieve advances that are a major factor behind the excellent torque and output characteristics. An optimum supply of fresh gas for the cylinders is assured thanks to four-valve technology and, above all, continuously variable and continuous intake and exhaust camshaft adjustment. The valves always open at the just the right time, in line with the current driving situation, thus substantially improving the gas cycle in the combustion chambers and reducing the amount of lost energy.

The “quadruple” continuously variable camshaft adjustment process is further enhanced by shifting camshafts, which are used to enable opening of the exhaust valves and, therefore, further improve the engine’s gas cycle. The exhaust cams are designed so that the valves open at different times during the exhaust process, depending on the firing order. As a consequence, the pressure fluctuations inherent in a V8 engine’s exhaust train are reduced. Thanks to a more constant residual-gas content, a higher knock limit and improved bottom-end and mid-range cylinder charging, the shifting camshafts increase the V8 engine’s torque and refinement. The effective mean pressure at 2000 rpm, for example, is around six percent (10.3 : 11.0 bar) higher than in a comparable engine not fitted with shifting camshafts.

Modified manual transmission and consumption-optimised automatic

The Mercedes engineers have adapted the tried-and-tested six-speed manual transmission to suit the high torques of the four-cylinder engines. For instance, they equip the new E 250 CDI BlueEFFICIENCY model with a modified transmission which, thanks to more effective gearing, a dual-mass flywheel and a larger clutch, is capable of transmitting the peak torque of 500 Nm. On account of the larger gears, the transmission is around 78 millimetres longer than its counterpart for the other four-cylinder models.

The five-speed automatic transmission, available as an option for the petrol models and four-cylinder diesel models (standard for the E 250 CGI BlueEFFICIENCY) has likewise been precision-modified and features a newly developed converter that reduces the hydraulic losses and, therefore, operates even more fuel-efficiently than previously.

Standard equipment for the new V6 and V8 E-Class models includes a seven-speed automatic transmission. In “C” mode, the 7G-TRONIC offers a consumption-optimised transmission mode that is always active after the engine is started. Earlier upshifts mean the powerplant operates at a lower engine speed level and, therefore, consumes less fuel. A further new development is the standstill decoupling function: if the car is stopped at traffic lights or stuck in traffic, for example, the transmission shifts to “N” position and thus reduces the engine load.

4MATIC: new all-wheel-drive technology saves up to 0.9 litres of fuel per 100 kilometres

For the E-Class, Mercedes-Benz offers a new generation of the 4MATIC all-wheel-drive system, which is even more efficient, even lighter and even more compact than the previously installed all-wheel-drive technology. These advantages over the outgoing model are evident in the improved traction and lower fuel consumption.

Three of the models are available with all-wheel drive: the E 350 4MATIC with a six-cylinder engine developing 200 kW/272 hp consumes 9.7 litres of premium unleaded petrol per 100 kilometres (provisional NEDC combined figure), making it 0.7 litres per 100 kilometres more economical than before.

In the case of the E 350 CDI 4MATIC BlueEFFICIENCY model (170 kW/231 hp), the fuel saving compared to the comparable predecessor model amounts to 0.6 litres per 100 kilometres. The V6 direct-injection diesel engine posts a fuel consumption figure of 7.3 litres per 100 kilometres (provisional NEDC combined figures). With the E 500 4MATIC model, meanwhile, the Mercedes engineers have succeeded in reducing the fuel consumption by 0.9 litres per 100 kilometres compared to the outgoing model.

The new E-Class 4MATIC models at a glance:

*provisional figures; **NEDC combined fuel consumption; ***NEDC

The latest-generation 4MATIC is a Mercedes development that only adds 50 to 70 kilograms of extra weight (depending on model) and boasts a compact design that takes up very little space in the transfer case area. It can therefore be installed without any modifications to the body and without impeding the front-passenger footwell. What’s more, the compact design makes for lower noise and vibration levels.

The permanent all-wheel-drive system, which works in tandem with the standard-fit Electronic Stability Program (ESP®), really comes into its own in poor weather conditions such as rain, snow or black ice as well as when starting off, accelerating, cornering at speed or driving on poor road surfaces. In these situations, the electronically controlled 4MATIC system greatly enhances traction, directional stability and road adhesion.

These exemplary handling qualities go hand in hand with hallmark Mercedes comfort thanks on the one hand to the selected damper control and on the other hand to the meticulous spring and damper tuning for the all-wheel-drive models, which largely replicates that for the rear-wheel-drive models. The modified AIRMATIC air suspension system is fitted as standard for the E 500 4MATIC model or as an optional extra for the two other all-wheel-drive Saloons. A further comfort-related aspect of the 4MATIC is the omission of conventional differential locks which, as other all-wheel-drive passenger cars show, affect steerability and handling.

Transfer case integrated in 7G-TRONIC automatic transmission

Unlike before, the transfer case is now integrated directly in the 7G-TRONIC transmission. The transfer case consists of a planetary centre differential and two bevel gears, which form the side output to the front axle. The centre differential produces the newly defined torque distribution between the front and rear axles – 45 to 55 percent (previously 40 to 60 percent) – which is noticeable above all in the improved directional stability, road adhesion and traction compared to the outgoing models.

A further highlight of the new powertrain concept is the compact side output to the front axle gear, which is based on a one-stage concept, meaning that a complete gear stage can be omitted compared to the previous 4MATIC drive system. Furthermore, the rear universal joint on the propshaft is integrated in the power take-off output gear. This space-saving design allows the propshaft to the front axle to be routed very close to the transmission without having to make modifications to the bodyshell.

The significantly higher efficiency of the 4MATIC drive system and the resulting lower fuel consumption compared to the predecessor models is largely down to the omission of the gear stage for the transfer case power take-off and an improved oil supply, since the integral design means that the transmission and the transfer case share the same oil circuit.

Multiple-disc clutch with lock between the front and rear axles

The new double-disc clutch located on the centre differential produces a basic locking torque of around 50 Nm between the front and rear axles. In this system, a cup spring preloads the clutch pack with a permanent force. If the wheels on one of the two axles start to spin, the relative movement of the discs causes a friction torque to be transmitted from the faster-turning axle to its slower-turning counterpart.

This principle of variable torque displacement between the front and rear axles improves the traction, directional stability and road adhesion of the 4MATIC models. The traction assistance provided by the double-disc clutch is especially noticeable when the friction ratio between the tyres and the road is low, since the clutch locks the powertrain mechanically during moderate starting if the friction coefficient between the tyres and the road is less than µ = 0.3 (more or less equivalent to snow). The wheels are prevented from spinning in such a way as to avoid what is known as the “polishing effect”, which leads to a reduction in the friction coefficient. Another advantage of the double-disc clutch is the improved load-change characteristics of the 4MATIC models.

Electronic traction system in place of differential locks

4MATIC uses the Electronic Traction System (4ETS), an additional component of the Electronic Stability Program (ESP®), in place of conventional differential locks. It has been modified and now provides a even higher level of comfort and even better traction. 4ETS is activated automatically when one or more wheels lose grip on the road. In this event, 4ETS brakes these wheels automatically and individually, thus increasing the drive torque at the wheels offering sufficient traction at the same time. These millisecond-fast braking pulses achieve the same effect as three differential locks. In addition, the 4ETS automatic braking pulses are based on the speed of the car.

The newly developed DIRECT CONTROL suspension with standard-fit amplitude-dependent damping system is one of the major factors behind the high degree of long-distance comfort provided by the E-Class. The shock absorbers adapt to the current driving situation, reducing the damping forces automatically when driving normally with low shock-absorber impulses and increasing the forces up to the maximum as required when cornering at speed or performing evasive manoeuvres. In this way, the chassis and suspension meet driver requirements in terms of road roar, tyre vibration and agility – without ever compromising on active safety.

The shock absorber system works by purely hydromechanical means without the need for sensors or electronics. Its core components are a bypass duct in the shock absorber’s piston pin and a control piston which moves in a separate oil chamber. When the shock-absorber bounce is low, the control piston moves oil through the bypass duct so that a lower damping force is produced at the actual shock-absorber valve. The result is “softer” shock-absorber characteristics and, consequently, a high level of ride comfort. If the excitation of the shock absorber is greater, the control piston moves to its limit position so that oil ceases flowing through the bypass duct, meaning that the full damping force is available.

Mercedes-Benz has modified several aspects of the three-link front suspension with McPherson struts and, as a result, has achieved excellent results in terms of ride comfort. In the interests of optimal axle kinematics, more favourable vibration characteristics and enhanced safety, the lower link level consists of two individual elements that serve as torque and cross struts. As well as offering more precise wheel location, the main benefit of these struts is that they allow better compensation for vibrations caused by tyre imbalance and fluctuations in braking forces than rigid wishbones. In addition, more crumple space is available in the event of a frontal crash. The third front-axle link is the track rod which connects the transversely installed steering gear to the wheels.

The spring struts consist of cylindrical, transverse force-compensating coil springs, double-tube shock absorbers and newly developed three-phase head bearings. In order to further optimise ride comfort, the Mercedes experts have chosen a starkly upright position for the spring strut so as to reduce the forces acting on the torque strut bearing. As a consequence, it was possible to reduce the bearing rigidity, which has a positive effect on the chassis’ tyre/road contact characteristics and rolling characteristics – for example when driving over expansion joints running across the road. The front anti-roll bar is connected to the spring strut, which is likewise actively involved in locating the front wheels.

Intelligent use of aluminium and steel reduces the weight of the front axle by twelve percent compared to the outgoing model. The forwards-slanting torque struts and the cross struts are made of aluminium.

High-strength subframes for axle, steering, engine and transmission

The front-axle components, steering gear, engine and transmission are pre-mounted on a high-strength-steel subframe which is bolted securely to the body’s side members, making it a key component in the front crash structure of the new E-Class: in the event of a frontal impact, the subframe forms a separate load-bearing path along which the impact energy is absorbed at specific points (see page 56). The stiffness at the connecting points between the subframe and the body where load is transferred as a result of the forces and vibrations produced by the chassis and suspension has been increased substantially, all of which translates into more agile and more precise handling.

Steering: variable ratio for exceptional safety and agile handling

As well as modifying the chassis and suspension, the Mercedes experts have newly developed the steering for the new E-Class, thus further enhancing steering precision, response and steering comfort. Standard equipment for the new E‑Class includes rack-and-pinion power steering with a variable ratio, which is more indirect in the central position compared to the outgoing model and, therefore, helps to improve directional stability and road adhesion at high speed. When the steering wheel angle exceeds around 100 degrees, the ratio becomes more direct to reduce the number of steering wheel turns required to park or manoeuvre.

Mercedes-Benz offers the Direct-Steer system that has proven such a resounding success in the SL-Class as an optional extra (standard for the V6 and V8 models). It fully lives up to its name by providing the driver with more direct response when cornering and, therefore, even more agile handling. In short, it delivers even more driving enjoyment. Hence the Direct-Steer system offers all the benefits of the previously installed speed-sensitive power steering system – less steering effort is required at low speed, when manoeuvring or parking, for example – whilst also enhancing handling dynamics.

The variable rack ratio, which adjusts in line with the steering angle, increases sharply as soon as the angle reaches five degrees, meaning that the driver does not have to move the steering wheel a great deal when cornering. The E-Class responds more spontaneously, and the driver has even more control over the car when greater manoeuvrability and agility are required, such as when driving on twisting country roads, i.e. at medium speed and with medium steering angles.

In other driving situations, meanwhile, the system offers the same advantages as the proven speed-sensitive power steering system and even goes one step further in some cases. For instance, the new Mercedes steering can be even more indirectly configured in the central position than previous steering systems, giving the driver an exceptionally assured steering feel when driving at high speed as well as improving straight-ahead driving and directional stability. When driving slowly or parking, the new technology combines with the speed-sensitive power steering to provide even more comfort than before because the direct ratio further reduces the steering effort required.

A further highlight is the power steering pump featuring an electrically controlled solenoid valve which controls a bypass opening and, as a result, allows metering of the oil quantity in line with requirements. This setup reduces the pressure and oil quantity when driving straight ahead – the power steering pump operates with a substantially reduced output and, consequently, helps to save fuel.

As previously, the E-Class is equipped with an individually adjustable steering column with a height adjustment range of +/- 25 millimetres and a reach adjustment range of 25 millimetres – meaning that, in this regard, the new E‑Class offers far more adjustability than other saloons in this market segment. A fully electrically adjustable steering wheel is included if the optional Memory package is ordered. To greatly enhance occupant safety, the steering column has been designed to collapse telescopically when hit by the driver with a certain degree of force in the event of a frontal collision. The extended deformation path, which is up to 100 millimetres longer, reduces the forces exerted on the driver’s upper body if a collision occurs.

Rear axle: multi-link independent suspension modified in several key areas

Mercedes’ multi-link independent suspension, which has proven itself time and again over a period spanning more than 25 years, has been further modified for use in the new E-Class in order to meet more stringent requirements in terms of comfort and agility. Modifications include the axle carrier’s front cross-bar, which now has a larger support base at the connecting points with the car’s body. As a consequence, the forces that can be transferred into the passenger cell are reduced: a comfort benefit that is particularly noticeable when driving over expansion joints running across the road, for example.

In keeping with the lightweight-design concept at the heart of the new E-Class, wheel location components such as struts, hub carriers and the metal sections of the elastomer bearings are largely made of aluminium. The rear-axle subframe is made of high-strength steel.

AVANTGARDE chassis with lowered body

As well as the standard-fit DIRECT CONTROL suspension with steel springs and amplitude-dependent damping system, Mercedes-Benz offers sports-tuned suspension with reinforced anti-roll bars and 17-inch light-alloy wheels for the AVANTGARDE line. If this suspension system, also available as an optional extra for the other model variants, is specified, the body is lowered by 15 millimetres.

If the AMG Sports package is ordered, the AVANTGARDE chassis is also equipped with 18-inch wheels, larger brakes and perforated front brake discs.

Air suspension: available in combination with continuously adaptive damping system for the first time

The new E-Class is the first Mercedes-Benz model to feature a combination of AIRMATIC air suspension and an electronically controlled damping system that adapts the damper characteristics with continuously variable control – individually for each wheel. This air suspension setup is available as an option for the V6‑powered E 350 CGI BlueEFFICIENCY and E 350 CDI BlueEFFICIENCY models and for the E 350 CDI BlueEFFICIENCY 4MATIC and E 350 4MATIC models; it is fitted as standard for the E 500/E 500 4MATIC models.

A total of seven sensors monitor the driving situation and the position of the body, sending their information to an electronic control unit, which also processes information concerning road speed, steering wheel angle, braking torque and engine torque, using this data to calculate the optimum shock-absorber characteristics. The system adjusts the damping force for each wheel individually, depending on the current road conditions and driving situation. When driving normally, soft damping settings are also selected if the road surface is poor. This mode offers the E-Class occupants maximum comfort without impairing the outstanding directional stability, road adhesion or handling safety. As the driving style becomes more dynamic, the shock-absorber settings are adapted continuously and therefore meet the driver’s need for enhanced agility.

The driver can pre-program the principal vehicle characteristics at the push of a button on the dashboard. There are two modes to choose from: “Comfort” or “Sport”. In Sport mode, the hydraulic forces of the shock absorbers are increased so as to allow even better directional stability and road adhesion at high speeds as well as reduce understeer at speeds of up to 120 km/h.

Newly developed McPherson struts

The Mercedes engineers have newly developed or modified many key aspects of the air suspension system. One particular highlight is the wheel-locating McPherson air suspension strut on the front axle, which combines the shock absorber, air bellows and air reservoir. The air bellows is much larger than on the outgoing model and has been further optimised using a new material. The special shape of the air bellows made it possible to use a McPherson air suspension strut in a luxury saloon for the first time.

Likewise, the experts paid special attention to the head bearings for the new air suspension struts, which have to transfer all the forces and, therefore, need to be capable of withstanding extremely high loads in both the compression and rebound stages. These requirements are fulfilled by an extremely rigid, diecast-aluminium flange that supports the bearing. It is the result of painstaking computer simulations and calculations of the complex interplay between the spring strut and the body. Its special design ensures ten times greater stiffness at the point where forces are applied in the air suspension strut area compared to the outgoing model. As a consequence, the newly developed spring strut bearings are one of the main reasons behind the exemplary vibration characteristics at the front of the car. Incidentally, the same benefits are achieved even if steel suspension is fitted.

Brakes: with Hill-Start assist and brake drying function

With the ADAPTIVE BRAKE, the new E-Class offers an innovative braking system incorporating additional assistance functions for even greater comfort and safety. One example of this is the practical HOLD function: after the E-Class has been braked to a standstill, briefly pressing the brake pedal a little further is all that is required to activate this function. The car is then held by the brakes, even if the driver’s foot comes off the brake pedal. In this way, the ADAPTIVE BRAKE prevents the car from rolling forwards when stopped at traffic lights or stuck in stop‑and-go traffic and from rolling backwards when facing up a slope. The HOLD function is deactivated automatically when the car moves off.

If the driver’s foot moves abruptly from the accelerator to the brake pedal before an emergency stop, the brake system increases the pressure in the brake lines and brings the pads into contact with the brake discs so that maximum braking power is available as soon as the driver hits the brake pedal. This priming of the brakes allows the system to assist the standard-fit Brake Assist system.

The ADAPTIVE BRAKE enhances safety in the wet by sending brief braking pulses at regular intervals to remove the film of moisture from the brake discs, allowing the brakes to work to full effect. This automatic brake drying function is always activated when the windscreen wipers on the E-Class have been operating for a certain time; the driver never even notices these precisely metered brake pulses.

Finally, the ADAPTIVE BRAKE assists the driver with hill starts. If the sensors detect that the Saloon is stopped on an uphill slope, a hill-start-assist function is activated automatically, maintaining a constant brake pressure for a brief period to prevent the E-Class from rolling backwards. The driver therefore has enough time to move their foot from the brake pedal to the accelerator without having to use the foot-operated parking brake.

Even more effective brake discs and brake booster

Large front and rear brake discsprovide an ideal technical basis for ensuring safe and reliable deceleration in any driving situation. The front and rear discs measure up to 344 millimetres and 320 millimetres in diameter respectively, depending on the engine version.

For brake cooling, the Mercedes engineers have developed two-section aluminium cover plates which have been tested in the wind tunnel and ensure that, whilst driving, the cool air flows from the underbody into the wheel arches and, ultimately, to the brake discs.

Further technical highlights in the new E-Class include the pedals. For the first time, Mercedes-Benz has used a steel and plastic hybrid design for the pedal support, which reduces weight and takes up less space than the previously used technology. The brake pedal, made from two shells that are welded together, is attached in this support. The shell design likewise helps to reduce weight and also ensures high torsional stiffness and bending strength.

Control systems: electronics for safe motorin

When it comes to active safety systems too, the E-Class features an array of state-of-the-art technology as standard, including anti-lock brakes, acceleration skid control, Brake Assist and the Electronic Stability Program. For ESP®, Mercedes‑Benz has developed control logicthat offers the driver even more effective assistance in critical cornering situations: precisely measured brake pulses sent to up to three wheels cause a moderate reduction in the car’s speed and help it to turn into the bend.

ESP® vehicle/trailer stabilisation, which is activated if the E-Class is equipped with a trailer coupling, detects dangerous oscillating movements of the trailer and restabilises it automatically by sending precisely measured brake pulses to the front wheels of the towing vehicle. If the danger is even more acute, the system applies the brakes to reduce the car’s speed automatically as well as reducing the engine torque before the precisely measured brake pulses are sent to the wheels to stabilise the trailer.

As an option, Mercedes-Benz can equip the new E-Class with a swivelling trailer coupling featuring a ball head that does not need to be fitted and removed every time it is used. Together with the socket, it swivels forwards underneath the body and cannot be seen when not in use. The E-Class has a maximum towing capacity of up to 2100 kilograms (braked) – a new record in this vehicle category.

The Electronic Stability Program also monitors the tyre inflation pressure and, if one of the tyres loses pressure suddenly, warns the driver. To do this, the system continuously compares the wheel speeds, which are dependent on the road speed, the vehicle load and the tyre inflation pressure. In addition, the control unit also analyses other dynamic handling-related ESP®sensor signals such as lateral acceleration, yaw rate and wheel torques in order to diagnose pressure loss in a tyre. Hence the system can detect discrepancies and indicate the information on a central display for the driver.

In order to ensure continued mobility in the event of a flat tyre, Mercedes-Benz offers the option of run-flat tyres. These are available in 245/45 R 17 format and feature self-supporting sidewalls, enabling Mercedes customers to continue driving for up to 50 kilometres at 80 km/h, depending on the vehicle load.

Wheels and tyres: 16-inch light-alloy wheels as standard

The range of wheels and tyres for the new E-Class offers a wealth of personalisation options for the Saloon. Mercedes customers have a choice of twelve wheel and tyre combinations in 16-, 17- or 18-inch format. The four-cylinder E 200 CDIBlueEFFICIENCY, E 220 CDIBlueEFFICIENCY and E 200 CGIBlueEFFICIENCY models are equipped with 16-inch nine-spoke light-alloy wheels and low-rolling-resistance 205/60 R 16 tyres as standard. Thanks to a special forging technique, the weight of the wheels has been reduced by a total of 9.6 kilograms.

For the E 250 CDI, E 350 CDI, E 350 BlueTEC, E 250 CGIand E 350 CGI BlueEFFICIENCY models, Mercedes fits 225/55 R 16 tyres and 7.5 J x 16 light-alloy wheels as standard. The top-of-the-range E 500 model is shod with 18-inch light-alloy wheels and 245/45 R 17 tyres ex factory.

For the ELEGANCE and AVANTGARDE lines, and for the AMGSports package, the Mercedes designers have selected special wheels and tyre sizes as standard equipment:

ELEGANCE:

ten-twin-spoke light-alloy wheels in

7.5 J x 16 format, tyre size 225/55 R 16

AVANTGARDE

five-twin-spoke light-alloy wheels in

8 J x 17 format, tyre size 245/45 R 17

AMG Sports package:

five-twin-spoke light-alloy wheels

front: 8.5 J x 18 format with 245/40 R 18 tyres

rear: 9 J x 18 format with 265/35 R 18 tyres

Mercedes-Benz USA (MBUSA) has reported February sales of 14,199 vehicles. While sales for the month were down from last year, the company’s February volume put it ahead of its mainstream competitors for the month.

A key contributor to February performance was the all-new 2010 GLK350, MBUSA’s versatile, compact SUV, which made a strong showing during its first full month on the market with sales of 1,918. The GLK’s February sales made it one of the company’s top-selling models behind the C-Class (3,990) and E-Class (2,104).

Sales gains were made by the iconic Mercedes-Benz SL and popular CLK models. Sales for the SL-Class increased 26.6 percent for the month with sales of 462 new vehicles (versus 365 vehicles in February 2008). The CLK-Class recorded sales of 1,134 new vehicles, a 15.4 percent increase over the same period last year (983 new vehicles).

Separately, through the Mercedes-Benz Certified Pre-Owned (MBCPO) program, MBUSA sold 5,795 vehicles in February; a 28.3 percent increase compared to February 2008 sales of 4,517 vehicles. Year-to-date sales for the MBCPO program are 12,548, a 54.1 percent increase over 2008 year-to-date sales (8,141 vehicles) during the same timeframe.

Mercedes-Benz USA February 2009 Sales Overview

Due to the ongoing downturn on almost all markets and the upcoming model changeover for the high-volume E-Class series, Mercedes-Benz Cars sold a total of 72,200 vehicles (February 2008: 96,800) worldwide in February (minus 25 percent ). The division has sold 134,500 (January-February 2008: 187,200) Mercedes-Benz, AMG, smart, and Maybach brand vehicles to date this year (minus 28 percent). Mercedes-Benz sold 63,600 vehicles in February 2009 (February 2008: 88,000 units). This represents a 28-percent decline from the February 2008 mark, which was the brand’s all-time sales record for the month of February.

smart delivered 8,600 vehicles (February 2008: 8,800 units) to customers worldwide last month (minus two percent). smart is now in the third year of its lifecycle. The smart fortwo has been available in the U.S.since one year now, and in February customers purchased 1,400 (February 2008: 1,100) of the innovative two-seater which is an increase of 29 percent.

Dr. Klaus Maier, Executive Vice President Sales and Marketing Mercedes-Benz Cars: “In recent weeks we’ve been observing a growing interest among German customers in our new passenger cars and our one year old pre-owned vehicles. In February, sales of the smart fortwo in Germany increased by 28 percent. What’s more, there was a substantial increase in orders for the A- and B-Class. The demand for our one year old pre-owned vehicles has also been developing very positively since the beginning of the year, with double-digit growth rates.”

In the U.S., despite the difficult market conditions, Mercedes-Benz sold 14,200 passenger cars in February (February 2008: 18,600, minus 24 percent), more than any other premium brand. Contributing to the result was the fact that the GLK got off to a good start. Sales of pre-owned vehicles also developed positively in the US, with 5,800 units sold (February 2008: 4,500), amounting to an increase of 28 percent.

In China, Mercedes-Benz is maintaining its position as the fastest-growing premium brand. In February, sales in China increased by 17 percent to 3,000 units (February 2008: 2,500). The B-Class has been available in China since January, and the smart fortwo will celebrate its market launch there this year.

The new E-Class coupé celebrates its world premiere at the Geneva Motor Show these days. Sales of the new model began on February 19, and the market launch is scheduled for May 9. “With this new coupé, Mercedes-Benz is continuing a tradition that has repeatedly thrilled E-Class customers throughout the model’s history,” said Dr. Klaus Maier. “The coupé’s dynamic design and its new engine generation combine emotion and efficiency in a very special way.”

The new E-Class coupé will be available shortly after market launch with Mercedes-Benz’ new fuel efficient four-cylinder diesel engine in the E 250 CDI BlueEFFICIENCY. With fuel consumption of only 5.3 liters per 100 kilometers and emissions of just 139 grams of CO2 per kilometer, the E 250 CDI BlueEFFICIENCY is one of the most economical vehicles in its class.

Mercedes-Benz presented the new E-Class sedan at the beginning of the year at the Detroit Auto Show. The model went on sale on January 12, and about 40,000 orders had been placed for it by the end of February, although the official market launch will not take place until March 28, 2009.

Welcome back ladies and gentlemen; I hope you all had a fantastic weekend. If you’re one of three people that have actually taken the time to read Mercedes-Benz’ Mercedesmagazine online, then we’ve got some news that will surely quicken your pulses this beautiful Monday morning. Mercedes has updated the website for their Mercedesmagazine service with a new design – one that offers “emotionally appealing photos, typography with a light touch and high-quality.”

Cutting through the marketing fluff, it’s the same writing as before – highly sterile, press release-styled content – wrapped in a newly animated and surprisingly annoying shell. As an example, the first issue is dedicated to the new 2010 Mercedes E-Class. I’ll let Mercedesmagazine take it from here:

“Another fast and furious day at the office – finally you call it a day: You climb into your car, the door slips into its lock. Already you’re in another world. Welcome home – to the new E-Class. The engine starts. It was a fine choice to choose the 150 kW/204 hp turbocharged direct injection diesel engine of the E 250 CDI. It is Mercedes-Benz’ new generation of 4-cylinder CDI units with cutting-edge common-rail technology, two-stage turbocharging and precise piezo injection. The new E 250 CDI burns just 5.3 liters of fuel per 100 kilometers (44 mpg), a figure only a compact car could previously have hoped to achieve. The new sedan is therefore 23 percent more frugal than its comparable predecessor model, the E 280 CDI.”

I think you get the idea. Will I be frequenting the new Mercedesmagazine? Probably not. But if you’ve been a fan of Mercedesmagazine in the past and love Flash-based webspecials, you’ll likely dig the new version of the site.

To view the Mercedesmagazine, head over to mercedes-magazine.com where you can check out the new design, or keep reading for the press release detailing the new service.

“Welcome home. The new E-Class.” That is the marketing campaign that has been chosen to represent the launch of the 2010 Mercedes-Benz E-Class. If you haven’t already guessed, it’s meant to highlight the fact that when inside the 2010 E-Class, one feels a sense of comfort and safety comparable to that of his own home. Accenting the “Welcome home” message will be other will be other witty catchphrases, including “Arrive as though you’ve never been away” and “The new Efficiency-Class: 204 hp, from 5.3 litres/100 km.”

According to Anders Sundt Jensen, Vice President Brand Communications Mercedes-Benz Cars: “The communicative focus is on design, safety and comfort of the new E-Class. These are addressed by the claim ‘ Welcome home’, which communicates this feeling across all channels. The highest standards with respect to design, safety, comfort and efficiency are aspects that have high importance all over the world. This enables us to use the campaign in more than 100 countries, ensuring that the new model will be uniformly positioned and communicated.”

As for where you can expect to see the new E-Class campaign, planned media outlets that will display the “Welcome home” theme include television, newspapers, magazines, billboards and websites, while a series of official Mercedes webspecials complete the advertising blitzkrieg.

For those of you looking to spruce up your Mercedes S-Class, Wald just sent us a few pics of their Black Bison kit for the model paired with their new Mahora M13 three-piece wheels. The Black Bison kit isn’t new – we told you about it last March – but in case you missed it, it consists of a new front and rear apron, sports fender ducts, side skirts and a few new spoilers.

As for the wheels, their design speaks for itself, but personally I find them to be a better match with the Black Bison kit than the black Portofino forged wheels originally featured on the model. To see more photos and judge for yourself, keep scrolling for a trio of pictures highlighting Wald’s latest creation (click any photo to enlarge).

The Geneva Motor Show will see the comeback of an intriguing product idea when Mercedes-Benz presents the Coupé range in the new E‑Class. Just three months after the presentation of the Saloon, the brand is therefore launching a new highlight in the new model series while continuing a tradition that has repeatedly met with great enthusiasm throughout the history of the E-Class.

The new E-Class Coupé offers a very special combination of two attributes for which the Mercedes brand is known: fascination and efficiency. With its classic coupé side aspect – no B-pillars and fully retractable side windows – the new two-door car is a particularly sporty interpretation of the E-Class’s dynamic design. At the same time the most aerodynamic variant of the Coupés achieves a new world best in terms of drag coefficient: with a Cd-figure of just 0.24, this model is the world’s most aerodynamically efficient series-production car. The model programme includes two new 4-cylinder engines, which consume up to 17% less fuel whilst offering a significant increase in performance and torque. The new E-Class Coupé’s standard-fit AGILITY CONTROL suspension adjusts automatically to the current driving situation. It combines driving enjoyment and excellent handling with the maximum comfort. The new E-Class Coupé will be in the showrooms of the European Mercedes-Benz dealerships and company-owned sales outlets at the beginning of May 2009.

The new Coupé offers all the technical innovations of the new E-Class series that one might expect to find in a sports-oriented luxury coupé. These include selective damper control, drowsiness detection, preventive occupant protection and the Active Bonnet. As a feature specific to the Coupé, the Dynamic Driving package allows different suspension setups at the touch of a button. Adaptive Main Beam Assist, road sign recognition and an automatic emergency braking system are other features with which the new series sets standards in this vehicle category.

The E-Class also takes on a pioneering role in the drive sector. The new diesels and direct-injection petrol engines combine efficiency with an effortless power delivery. The engine line-up includes two new four-cylinder models which deliver significantly more power and torque while consuming up to 17 percent less fuel. The best example is the E 250 CDI BlueEFFICIENCY Coupé, which consumes 5.3 litres of diesel per 100 kilometres and emits 139 grams of CO2 per kilometre, making it one of the most economical vehicles in its class.

The exemplary, low fuel consumption has not only been achieved because of the new engines, but also with a number of practical measures. These include on-demand activation of the steering and fuel pumps, the use of tyres with low rolling resistance and an alternator control system which takes account of the current driving situation and the vehicle’s electrical power requirements, plus the very decisive factor of outstanding aerodynamics .

Design which expresses passion and effortless superiority

The design of the new two-door model includes traditional styling elements which give Mercedes-Benz Coupés their unmistakable identity: for example the side windows, which are not interrupted by a B-pillar and are fully retractable. Another hallmark of Mercedes Coupé design is the sports radiator grille with the large central star. At the same time, however, the new model points the way to the future with an exciting, contemporary design idiom.

At the same time the Coupé shows its close family resemblance to the E-Class Saloon. This is shown by the ‘twin-headlamp face’, with rhomboid contours but somewhat sportier, sharper treatment for a more dynamic and incisive look. Another design feature which the Coupé shares with the Saloon is the powerful contour of the rear wing – a styling cue which also gave the S 220 “Ponton” Coupé of 1955 its athletic appearance.

Although it shares family traits with the Saloon, the Coupé has its own, distinct identity characterised by effortless superiority and a greater sense of passion. The arrow shape of the entire front section from front bumper to radiator to bonnet, the more extreme interpretation of the twin headlamp face and its more sinewy build give it a racier and more dynamic presence.

Newly developed seats with a sporty design

The seats of the E-Class Coupé are new developments whose design and techno-logy reflect the sporty nature of this two-door Mercedes. They are electrically adjustable for seat height and backrest angle as standard. The high, sports car-like seat backrests have a practical Easy-Entry function to make access and egress easier for rear-seat passengers. In conjunction with electric seat adjustment with memory (an optional extra), the front seats are equipped with electropneumatically adjustable four-way lumbar supports; these are able to provide anatomically favourable support for the lower spine, which further improves seating comfort.

Luxury seats with leather upholstery and active ventilation are available as optional extras, as are newly developed multicontour seats with inflatable air chambers in the front seat cushions as well as in the centre and side bolsters of the backrests. Two comfortable individual seats are available for the rear passengers. These feature backrests which can be folded down individually or together to increase the capacity of the luggage compartment.

Engines: fuel consumption down by 17 percent

The diesel in the E 250 CDI BlueEFFICIENCY Coupé is the top-of-the-range unit in the new generation of Mercedes-Benz four-cylinder engines, which are notable for features such as two-stage turbocharging, precise piezo injectors and the latest common-rail technology. The engine has an output of 150 kW/204 hp and develops a maximum torque of 500 newtonmetres which is available from just 1600 rpm. This means that it is some 36 percent more powerful than the four-cylinder diesel in the preceding model yet consumes 17 percent less fuel: 5.3 litres per 100 kilometres (combined NEDC consumption, provisional figure). This corresponds to a carbon dioxide emission level of 138 grams per kilometre.

The turbocharged V6 diesel engine with common-rail direct injection remains in the line-up. Fitted in the E 350 CDI BlueEFFICIENCY Coupé, it develops 170 kW/231 hp (previously: 165 kW/224 hp) and consumes 6.8 litres per 100 kilometres (combined) in the NEDC cycle. Its carbon-dioxide emissions are 179 grams per kilometre.

Two new petrol engines with direct injection

Mercedes-Benz has also chosen to move over to direct-injection technology for its petrol engines. Once again, the E-Class Coupé points the way: the powerplant at work under the bonnet of the E 250 CGI BlueEFFICIENCY Coupé is a newly developed four-cylinder direct-injection unit with 150 kW/204 hp and a five-speed automatic transmission as standard. This engine makes do with 7.0 litres of fuel per 100 kilometres (combined NEDC consumption, provisional figure). CO2 emissions are 164 grams per kilometre. This is some 13 percent less than the figure for the previous four-cylinder engine (135 kW/184 hp) with conventional fuel injection.

Mercedes-Benz has replaced the previous V6 petrol engine with the world’s first six-cylinder unit featuring spray-guided direct petrol injection in the new E 350 CGI BlueEFFICIENCY Coupé. This engine develops 215 kW/292 hp – an extra 15 kW/20 hp – and consumes about 14 percent less fuel than the previous V6 engine: its combined NEDC consumption per 100 kilometres is just 8.5 litres. This corresponds to 199 grams of CO2 per kilometre.

In the top-of-the-range model, the E 500 Coupé, the muscular V8 engine with 285 kW/388 hp and 530 newtonmetres of torque offers the performance characteristics of a sports car. Mercedes engineers have enhanced details of the eight-cylinder unit, reducing the fuel consumption (compared to the preceding model) by 0.5 litres to 10.9 litres per 100 kilometres (combined NEDC consumption). All the engines in the new E-Class Coupés meet the EU5 exhaust emission standard.

Safety: sensors, radar and cameras for safe driving

The safety systems newly developed for the E-Class are based on accident research findings; they can make a valuable contribution to enabling safe, accident-free driving, improving vehicle occupant protection and, moreover, helping to increase the safety of other road users. These trend-setting developments are also available for the new E-Class Coupé, or are included in its standard equipment. Based on highly sensitive sensors, cameras and radar systems, they turn this two-door model into an “intelligent partner” able to see, feel and react reflexively in critical situations and, if necessary, act independently if the danger of an accident is acute.

Drowsinessis one of the most common causes of accidents on motorways. This is why Mercedes experts have developed the ATTENTION ASSIST system which forms part of the standard equipment of the new E-Class Coupé. As the vehicle is being driven, the system continuously evaluates more than 70 different parameters in order to identify driver drowsiness and provide a warning before the dangerous microsleep phase begins. Observing the driver’s steering behaviour has proved to be a particularly strong indicator: several years of practical research by Mercedes engineers have shown that drowsy drivers make minor steering errors which they often correct very rapidly in a characteristic way. This steering behaviour is recognised by a special steering angle sensor.

Also fitted as standard is the PRE-SAFE® anticipatory occupant protection system – a Mercedes invention which has received a number of awards and which is not offered by any other vehicle in this class. If there is an immediate danger of an accident occurring, the system activates protective measures for the driver and front passenger as a precaution so that the seat belts and airbags can provide their full protective effect on impact. This warning of an impending accident is possible because PRE-SAFE® uses the sensors of the Brake Assist system and the Electronic Stability Program (ESP®) to identify potentially critical dynamic handling situations.

Adaptive Main Beam Assist for the best possible road illumination

Like the Saloon, the new E-Class Coupé also offers the latest lighting technology. The headlamps adjust continuously to the current driving situation and react automatically to offer the driver the best possible degree of road illumination at all times. This task is taken care of by the Adaptive Main Beam Assist function: a camera fitted on the inside of the windscreen allows the system to detect oncoming vehicles/vehicles in front and automatically controls the headlamps to prevent the other road users from being dazzled. As a result, the range of the dipped-beam headlamps can increase from the current norm of 65 metres to as much as 300 metres. If the road ahead is clear, the system performs a gradual transition to high-beam mode.

Adaptive Main Beam Assist is based on the bi-xenon headlamps, which Mercedes-Benz offers in combination with LED daytime driving lights.

Automatic emergency braking when a collision is imminent

The well-proven assistance systems from the S-Class which help to prevent rear-end collisions are now available for the E-Class Coupé, too. They use long and short-range radar sensors to monitor the traffic situation ahead of the vehicle and warn the driver if there is a risk of an accident. Mercedes-Benz combines these technologies in the DISTRONIC PLUSsystem; along with the proximity control system – which automatically maintains the Coupé at a set distance from the vehicle in front and can brake it to a standstill if required by the traffic situation – this comprises Brake Assist PLUS and the PRE-SAFE® Brake.

Brake Assist PLUS intervenes if there is suddenly a very rapid reduction in the distance. In this situation, the system warns the driver and almost instantaneously calculates the degree of braking assistance necessary to prevent a collision. This brake force is available immediately the driver depresses the brake pedal. Depending on the speed and distance, it allows controlled braking to a defined point or – if necessary – emergency braking.

The PRE-SAFE® Brake goes a step further and automatically brakes the E-Class if there is imminent danger of a collision and the driver does not react to the warnings. This can reduce the severity of an impact considerably, as the system can be regarded as something like an “electronic crumple zone” which offers the occupants an even greater degree of safety.

Most comprehensive array of safety features in this vehicle category

With seven standard-fit airbags, belt tensioners and belt force limiters on all seats, as well as crash-responsive head restraints for the driver and front passenger, the new E-Class Coupé offers the most comprehensive array of safety features in this vehicle category. The range of airbags, which can deploy in thousandths of a second in an accident, comprises front and side airbags for the driver and front passenger, a kneebag for the driver and windowbags. Rear sidebags are available as an optional extra.

The front crumple zone has four independent impact planes which allow the forces to be distributed over a wide area while bypassing the passenger cell. Furthermore, increased use of extra-high-strength steel alloys helps the vehicle body to withstand high impact loads. In fact, particularly strong grades of steel like this account for about two thirds of all the sheet metal used in the bodyshell of the E-Class Coupé.

An Active Bonnet, which forms part of the standard equipment, is the latest development to result from Mercedes-Benz’s long-standing and successful commitment to pedestrian protection. In the event of an impact, a system of springs raises the rear section of the bonnet by 50 millimetres within a fraction of a second, thereby increasing the available deformation space. A special feature of the Mercedes system is its reversible mechanism which allows the driver to reset the Active Bonnet without having to visit a workshop.

Comfort: advanced technology for a new driving experience

Along with safety, comfort has always been one of the outstanding qualities of the E-Class. Here, too, the Coupé lives up to the high standard set by the Saloon and demonstrates further noticeable progress, especially with regard to ride, seating and climate comfort. Another important comfort factor is the generous interior space, which Mercedes engineers created by increasing both the length and width of the vehicle body by 46 millimetres. This resulted in the distance between the front and rear seat reference points – an important dimension for the occupants’ freedom of movement – increasing by ten millimetres to 789 mm while the elbow width improved by up to 49 millimetres, compared to the preceding model.

High standard of ride comfort through selective damper control

The new E-Class Coupé’s standard-fit AGILITY CONTROL suspension adjusts automatically to the current driving situation. In order to provide the best possible ride comfort, this system reduces the damping during normal driving but immediately applies the maximum damping force during dynamic cornering or sudden evasive manoeuvres. This ensures optimum stabilisation of the Coupé.

As an alternative to the standard-fit AGILITY CONTROL suspension which is set up for comfort, a variant with a sportier damper response and more direct steering – the AGILITY CONTROL sports suspension – is available as an optional extra. To meet the requirements of even more demanding drivers, Mercedes-Benz has developed a dynamic handling package with an electronically controlled damping system. This processes sensor data about the current driving situation and adjusts the shock absorbers separately for each wheel. Furthermore, the driver can switch between two drive modes – Comfort and Sport – which make corresponding adjustments to the suspension set-up, accelerator response and the shift points of the automatic transmission. A newly developed speed-sensitive sports steering system with a more direct ratio and variable centring is also included in the dynamic handling package.

In order to allow a comparison of suspension characteristics, Mercedes engineers have developed the body index – a composite formula which is calculated from the readings for various typical driving manoeuvres. The body index is an indi-cation of how well the suspension is linked to the body, how closely the car hugs the road and how nimble the handling is through fast bends. The higher the figure, the sportier – i.e. the firmer – the suspension characteristics.

The body index shows how the dynamic handling package is able to meet customers’ requirements for dynamism and comfort in equal measure: the index figure of 2.06 attained in Sport mode is reduced to 1.89 – a typical level for a saloon – when Comfort mode is selected.

Individual climatic comfort at the touch of button

The newly developed luxury automatic climate control system regulates the temperature, volume and distribution of the air in three zones to meet the requirements of the driver, front passenger and rear passengers. What’s more, for the first time, this optional THERMOTRONIC system allows the selection of different climatisation modes: the occupants can choose “Diffuse”, “Medium” or “Focus” modes at the touch of a button in order to adapt the air volume and distribution to their personal preferences while still benefiting from the convenience and comfort of automatically regulated climate control. Fitted as standard in the E-Class Coupé, the THERMATIC two-zone automatic climate control has been enhanced to offer five percent more heating and cooling power than the version fitted in the predecessor model.

Infotainment system with colour display in the dashboard

The well-proven operating concept from the S-Class, comprising the multifunction steering wheel, Controller on the centre tunnel, colour display in the dash-board and direct selection buttons also offers the occupants of the new E-Class Coupé a very high standard of operating comfort.

The Controller puts all the functions of the advanced infotainment system – such as the radio, CD/DVDplayer, telephone and navigation system – at the fingertips of the driver and front passenger. The Audio 20 CD radio with eight loudspeakers, a CD player and a Bluetooth interface for a mobile phone is fitted as standard. Customers who specify the optional COMAND APS multimedia system benefit from additional functions: a Europe-wide hard-disc navigation system, a DVDchanger, the Music Register (storage for about 1000 music tracks) and voice control with whole-word recognition. Further options for even greater listening pleasure are available in the form of a 500-watt surround sound system, a media interface for connecting external MP3 players and a tuner for digital radio reception.

Model range: individuality through variety

With an initial line-up of five engines, three suspension variants, a wide choice of colours, six different wheel/tyre combinations and many optional extras, the new E-Class Coupé offers plenty of scope for customers to turn their individual automotive dreams into reality. The basis for configuring the look and feel of the Coupé is provided by the ELEGANCE and AVANTGARDE interior concepts.

These not only offer different upholsteries and items of trim, but are complete configuration packages designed to create a harmonious atmosphere. Depending on the choice, the interior differs in its colour scheme and mix of materials to emphasise the elegant or progressive character of the Coupé.

The AMG Sports package, on the other hand, clearly focusses on agility and performance potential. AMG bodystyling includes the unmistakable contours of the AMG front apron with large air intakes, AMG side skirts and the expressive AMG rear apron with a black insert. High-sheen 18-inch AMG light-alloy wheels in a 6 twin-spoke design with wide-base tyres in size 235/40 R 18 at the front and 255/35 R 18 at the rear provide further highlights. The AGILITY CONTROL sports suspension with a stiffer spring, shock absorber and stabiliser setup is combined with large, perforated brake discs at the front, plus brake callipers with Mercedes-Benz lettering. Perfect road contact is ensured by the sports speed-sensitive steering with a more direct ratio.

Striking interior features include upholstery in black ARTICO man-made leather. Leather or the particularly exclusive nappa leather is also available in a wide range of colours. Multicontour seats for the driver and front passenger provide the best possible adjustment to personal comfort preferences, thereby ensuring outstanding long-distance comfort.

With production limited to the first few months, the E-Class Coupé is also available as a Prime Edition series which particularly emphasises the new model’s character with selected, high-grade features. Among the most eye-catching are the palladium silver metallic paint finish, a panoramic glass sliding roof and 18-inch AMG high-sheen light-alloy wheels painted in titanium grey. Inside, a designo-interior with two-tone designo leather upholstery, matching designo floor mats and a sports pedal cluster of brushed stainless steel rounds off the exclusive overall impression.

With the new E-Class, Mercedes-Benz is presenting the pacemaker when it comes to safety, comfort and environmental compatibility in this market segment. With more than 20 new or further technical developments, this saloon further consolidates the leading position of Mercedes-Benz in the luxury class. They include trailblazing innovations for safe driving that are available from no other manufacturer worldwide in this combination. Examples include the standard Attention Assist, Adaptive Main Beam Assist and automatic emergency braking, which is activated when there is acute danger of a collision.

Mercedes-Benz has improved the already exemplary long-distance comfort of the E-Class even further in the new saloon, including intelligent bodyshell technology with up to 30 percent greater rigidity, further improved seats and a newly developed suspension whose shock absorbers automatically adjust to the current driving situation. The optional air suspension now works together with an electronic damping system.

The outstanding safety and comfort of the E-Class are matched by its environmental compatibility and economy: the four- and six-cylinder engines are direct-injection units, and consume up to 23 percent less fuel than before. The combined NEDC consumption of the new four-cylinder diesel engines is just 5.3 litres per 100 kilometres, which corresponds to 139 grams of CO2 per kilometre. All the engines for the new E-Cass meet the EU5 emission standard, and in the case of the E 350 BlueTEC the emissions are already below the EU6 limits planned for 2014.

Apart from the engines, the BlueEFFICIENCY package for the E-Class is in large part responsible for a considerable fuel saving. Engineers from every development department have worked together to optimise assemblies and components, to save fuel by means of reduced weight, a new form, improved functioning or efficient energy management.

The work done in the wind tunnel was particularly successful, for with a drag coefficient of only 0.25, the new E-Class is the world’s most aerodynamically efficient luxury saloon. It betters the already good Cd figure of the preceding model by another four percent, which represents a fuel saving of around 0.25 litres per 100 kilometres when driving at a motorway speed of 130 km/h. The aerodynamics are for example improved by variable fan louvres, which control the airflow to the engine compartment in line with requirements.

Other BlueEFFICIENCY measures include newly developed tyres with up to 17 percent lower rolling resistance, energy-saving control of the generator, fuel pump, air conditioning compressor and power steering, and the ECO start/stop functionwhich switches the engine of the new E 200 CGI off when idling. Displays in the speedometer inform the driver how much fuel is being consumed (per 100 kilometres), and when he should shift to the next higher gear in the interests of an economical and environmentally conscious style of driving.

The range of engines available for the new E-Class comprises four, six and eight-cylinder units with outputs from 100 kW/136 hp to 386 kW/525 hp. The four-cylinder engines are newly developed direct-injection units, which develop a higher output and torque than the comparable V6-engines of the preceding series despite a smaller displacement. The strategy is to replace to replace large, naturally aspirated engines with turbocharged units which excel with advantages such as lower weight, reduced internal friction and more economical operating characteristics.

Engines: new CDI-four-cylinder units with a fuel consumption of just 5.3 litres and 139 grams of CO2 per kilometre

With three completely newly developed four-cylinder engines, the E-Class also remains one generation ahead where diesel technology is concerned. These engines feature latest-generation common-rail direct injection, fast piezo-electric injectors, improved exhaust gas recirculation and an innovative twin turbocharger, making for fast responsiveness and good performance characteristics. To express this in figures, the E 250 CDI with 150 kW/204 hp and 500 newton metres develops a 25 percent higher torque than the previous V6 diesel engine, but uses around 23 percent less fuel at only 5.3 litres per 100 kilometres (combined NEDC consumption). This corresponds to 139 grams of CO2per kilometre.

The new four-cylinder diesel engine also powers the E 220 CDI with 125 kW/ 170 hp and the E 200 CDI with 100 kW/136 hp, also with a fuel consumption of only 5.3 litres per 100 kilometres.

The top model in the new E-Class diesel range is the six-cylinder E 350 CDI with an output of 170 kW/231 hp, which uses 0.5 litres per 100 kilometres less fuel than the previous E 320 CDI. From autumn 2009 the V6 diesel will also be available as a BlueTEC model with the world’s best emission control technology. The E 350 BlueTEC develops 155 kW/211 hp and meets the EU6 exhaust emission standards planned for 2014. All the other engine variants in the new E-Class meet the EU5 limits.

Petrol engines: 20 percent fuel saving thanks to direct injection

The E 200 CGI and E 250 CGI are equipped with the newly developed four-cylinder direct-injection engine with a displacement of 1.8 litres, turbocharging and variable intake and exhaust camshafts. The E 200 CGI (135 kW/184 hp) is equipped with a six-speed manual transmission and the ECOstart/stop function as standard, and consumes only 6.8 litres of premium petrol per 100 kilometres (combined NEDC consumption, provisional figure). This equates to 159 grams of CO2per kilometre.

In the E 250 CGI (150 kW/204 hp), which has a five-speed automatic transmission as standard, maximum torque is now 310 newton metres, which represents an increase of more than 26 percent over the previous V6-engine. At the same time the NEDC fuel consumption is reduced by over 20 percent to 7.4 litres per 100 kilometres, equating to 175 grams of CO2per kilometre (provisional figures).

As before, the E 350 CGI with direct petrol injection (215 kW/292 hp) and the top-of-the-line E 500 (285 kW/388 hp) are included in the range of engine variants in the new E-Class. Detailed improvements have reduced the fuel consumption of these V6/V8 models by up to 0.6 litres per 100 kilometres. As a product from Mercedes-AMG, the new high-performance E 63 AMG develops 386 kW/525 hp.

The V6 and V8-models are equipped with a seven-speed automatic transmission and steering wheel selector lever as standard.

On request the V6 models E 350 CDI and E 350, as well as the eight-cylinder E 500, are available with latest-generation Mercedes all-wheel drive. This system distinguishes itself from previous all-wheel drive technology with greater efficiency, lower weight and more compact construction. These advantages produce noticeably better traction and fuel savings.

Safety: “Intelligent” partner thanks to unique combination of assistance and protection systems

For more than 50 years, the saloons in the E-Class and their predecessors have been acknowledged as trendsetters in the safety field. The new saloon continues this tradition with an unrivalled combination of the very latest assistance and protection system whose concept and development are based on what actually happens during accidents. These technologies make the E-Class an “intelligent partner”who can see, feel, react reflexively in critical situations and if necessary act independently to prevent accidents or mitigate their consequences. With this concept the new Mercedes model not only protects its own occupants, but also contributes decisively to the greater safety of other road users.

The new E-Class is the first automobile in the world whose headlamps adapt to the traffic situation and respond automatically to avoid dazzling other drivers. The optional Adaptive Main Beam Assist uses a camera on the windscreen to recognise oncoming traffic and vehicles moving ahead, and controls the headlamps so that their beams do not reach the other vehicle. This achieves the best possible road illumination in a given situation. The range of the dipped headlamp beams can be extended from 65 to up to 300 metres. If the road ahead is clear, the system performs a gentle transition to high beam.

Mercedes-Benz offers this new system as a light & sight package that includes bi-xenon headlamps, the Intelligent Light System and LED daytime driving lights.

The Lane Safety package for the new E-Class includes Blind Spot Assist familiar from the S-Class, and as a new development, Lane Keeping Assist which seeks to prevent the vehicle from leaving the road unintentionally. When the system recognises that the car is drifting from its lane, the driver is prompted to take countersteering action by brief but unmistakable vibrations of the steering wheel. The images from the windscreen camera are also used by the new, optionally available Speed Limit Assist , which recognises speed limit signs as the car passes them, then displays the relevant speed limit in the speedometer.

Night View Assist from the S-Class is now also available as an optional extra for the new E-Class. Mercedes-Benz has improved this system with a special pedestrian detection function: as soon as Night View Assist Plus recognises pedestrians ahead of the car, they are highlighted in the onboard display to provide a greatly enhanced warning effect.

Detection of drowsiness based on 70 parameters as standard

Thanks to an innovative technology, the new E-Class has developed a highly sensitive means of monitoring its driver’s attention level, and warns him of drowsiness in good time. This new ATTENTION ASSIST drowsiness detection system, which is standard equipment, is equipped with highly sensitive sensors that continuously monitor more than 70 different parameters. Observing the driver’s steering behaviour has proved to be a particularly strong indicator: several years of practical research by Mercedes engineers have shown that drowsy drivers make minor steering errors that can often be rapidly corrected in characteristic ways. These corrections are recognised by a highly sensitive steering angle sensor.

Automatic emergency braking when a collision is imminent

The well-proven, radar based assistance systems from the S-Class are now also optionally available to E-Class customers. A further development of the long-range radar sensor now has a range of 200 metres (previously 150 metres), and is able to monitor the mid-distance so that dynamic events such as a vehicle ahead suddenly pulling out to overtake can be detected even more effectively. The two wide-angle short-range radar sensors, which have a range of around 30 metres, continue to be included in the system.

The radar-supported systems are able to assist the driver with emergency braking. Their sensors are linked to the Brake Assist PLUS system, which automatically calculates the braking pressure to prevent a collision in critical situations. The driver is given an acoustic and visual warning at the same time. When the brake pedal is depressed, the system immediately activates the calculated level of braking assistance.

If the driver fails to respond to the warnings, the radar system first initiates partial braking action. As a second stage, if there is still no driver response and a collision is unavoidable, emergency braking is initiated. This can considerably lessen the severity of an accident, i.e. the system acts as something like an “electronic crumple zone”.

Active bonnet, seven airbags and PRE-SAFE® as standard

During the course of its development, the new E-Class was subjected to more than 150 high-speed crash tests and a total of more than 17,000 realistic crash simulations. The crumple zone principle invented by the Mercedes safety pioneer Béla Barényi has been continuously improved by the engineers in Sindelfingen. The front-end deformation zone of the E-Class acts on four independent levels, and is even more effective than before. The increased use of highest-strength steel alloys also helps to ensure that the bodyshell is able to withstand high impact forces. Around 72 percent of all the body panels are made from these high-tech steels – yet another unrivalled figure in passenger car development.

With seven airbags as standard, belt tensioners, belt force limiters, crash-responsive head restraints and ISOFIX child seat attachments, the new E-Class has even more extensive safety features than the preceding model. Another new feature is the active bonnet, which is a continuation of many years of commitment to pedestrian protection on the part of Mercedes-Benz. It is standard equipment in the new E-Class. In the event of an impact, a system of springs raises the rear section of the bonnet by 50 millimetres within fractions of a second, thereby increasing the available deformation space. Thanks to the cleverly conceived mechanism, the driver is able to reset the active bonnet to its normal position himself, without visiting a workshop.

Another standard feature is the preventive occupant protection system PRE-SAFE®. In potentially hazardous situations this reflexively activates precautionary protective measures for the vehicle occupants, so that the seat belts and airbags are able to fulfil their protective function to the full during an impact.

Comfort: Further progresses with adaptive shock absorbers and improved air suspension

As in the safety field, the E-Class has been setting the standards for long-distance comfort in this vehicle class for several decades. Bettering the already high level of the preceding series, Mercedes engineers have achieved further advances with the new saloon – especially where ride, seating and climatic comfort are concerned.

Standard equipment includes a further improved suspension with adaptive shock absorbers. These automatically adapt to the current driving situation by reducing the damping forces when driving normally, thereby noticeably improving ride comfort. When taking bends at speed or during rapid evasive action, the system switches to the maximum damping effect so that the saloon is stabilised to best effect.

A version with dynamic damping characteristics and a lowered suspension is available as an optional alternative to the standard suspension (standard for the AVANTGARDE line).

The air suspension system optionally available for the V6 models (standard in the E 500/E 500 4MATIC) has for the first time been combined with an electronically controlled damping system, which processes various sensor signals and controls each wheel independently. In this way Mercedes specialists have achieved significantly better ride comfort while improving handling safety and agility at the same time. The driver is able to select either comfort or sport mode at the touch of a button.

Well-proven seat technology with a new design

Where seat development is concerned, Mercedes-Benz had added a new quality to a well established Mercedes concept, namely padded seat piping – a sophisticated and demanding upholstery technique that is only used by Mercedes-Benz. This involves the insertion of an additional foam filling under the fabric or leather cover, and gives an immediate feeling of comfort and wellbeing when sitting in the car. There are different versions of this padded seat piping: in the basic model and AVANTGARDE line the upholstery is transversely contoured, while the ELEGANCE line has longitudinal piping and is reminiscent of the well-known and highly effective Mercedes seat design from the 1960s and 70s.

Active multicontour seats with massage function from the S-Class

The active multicontour seat package (optional) includes newly developed multicontour seats with comfort head restraints and a two-stage massage function in the backrest that has proven highly successful in the S-Class. Depending on the steering angle, lateral acceleration and vehicle speed, fast-acting piezo-electric valves on the air chambers in the backrests vary their pressure and volume to give the driver and front passenger even better lateral support.

On request the E-Class is also available with a rear seat unit consisting of two comfortable, single seats. This rear-seat comfort package includes seat heating, leather upholstery, a centre console, comfort head restraints, roller blinds in the rear doors, an electrically operated roller blind for the rear window, comfort sun visors and a through-loading facility to the boot.

Individual climatisation modes at the touch of a button

Mercedes-Benz has developed a climate control system for the E-Class which not only allows individual temperatures to be set in three zones – for the driver, front passenger and rear passengers – but also offers different “climatisation modes”. If this optional THERMOTRONIC system is specified, the occupants of the new E‑Class are able to select “Diffuse”, “Medium”or “Focus”at the touch of a button, and adapt the air volume and distribution to their personal preferences without sacrificing the convenience of automatic mode. In standard trim the new E-Class is equipped with the two-zone THERMATIC automatic climate control system.

Design: Distinctive lines flow as an expression of effortless grace and status

In 1995 the E-Class was the first Mercedes model to appear with the highly acclaimed twin-headlamp face – a highly symbolic design feature that still characterises the identity of the E-Class. Nonetheless, the design idiom has remained fluent even for this characteristic styling feature, and has been adapted to suit the self-assured, masculine overall appearance of the saloon. The designers have now reinterpreted these four “eyes”as rectangles, with a direct reference to the interesting geometrical shapes found in cubism. They have the effect of precious gems that have been precisely set into the wings. In the same way, the radiator grille with its three-dimensional chromed surround, dynamic arrow-shape and more upright position underlines the status of the car as the epitome of a business saloon.

A sophisticated interplay between lines and surfaces is one of the hallmarks of today’s Mercedes design. Large concave or convex surface areas are structured by taut, clearly defined lines. This design concept has been perfected down to the last detail in the new E-Class. The flank contours become connecting features that influence the entire body design, i.e. not just the side aspects but also the front and rear-end styling.

At the rear this harmonious flow culminates in a new feature, namely a graceful line that follows the rear wheel arches and lends a clear shape to the imposing, muscular contours of the rear wings. Here Mercedes aficionados will recognise styling features reminiscent of the famous “Ponton Mercedes” introduced in 1953, which already emphasised its sovereign character with these striking contours at the time — a symbolic feature, and at the same time a hallmark of the E-Class that well illustrates how tradition is made to harmonise with the future in this model series.

With typical Mercedes attention to detail, the designers have also given great attention to the interior of the new E-Class, ensuring that every feature appeals in both emotional and functional terms with its form, colour or material. The result is a harmonious whole – an atmosphere in which the car’s occupants immediately feel safe and protected, and long journeys can be taken without any feeling of effort or stress. In short: Typically E-Class, welcome home.

Model range: High level of standard appointments and individual variants

Individuality and variety have always been two of the outstanding attributes of the E-Class. The new saloon not only provides Mercedes customers with a choice of ten engines and three suspension variants, but also two design and equipment lines, 12 wheel/tyre combinations in 16, 17, 18 or 19-inch size, twelve exterior paint finishes and six different seat upholstery materials in up to five colour combinations to suit their individual preferences. The choice of interior trim has been doubled versus the preceding series, with the range now including high-gloss exotic wood, open-pored wood and aluminium trim.

Standard specifications already include 16-inch light-alloy wheels in a nine-spoke design, eucalyptus or embossed aluminium trim (optional) and a four-spoke multifunction steering wheel lined in fine nappa leather with chrome inserts. Also included in the standard equipment is the Audio 20 CD infotainment system with a twin receiver, CD-player, eight loudspeakers and a Bluetooth interface for a mobile phone. The colour display in the centre of the dashboard can be operated by the driver or front passenger, using the Controller on the centre console.

The individualisation programme for the E-Class is based on two design and equipment lines. The ELEGANCE line lives up to its name with a decidedly elegant, classic appearance. This is in part due to additional features such as a chrome-plated radiator grille with four silver-painted louvres, 16-inch light-alloy wheels in a ten twin-spoke design, burr walnut trim and stylish ambient lighting with fibre optics that frame the dashboard and door panels.

In contrast the AVANTGARDE line shows the E-Class in a decidedly modern and innovative light. This is ensured by additional standard features such as bi-xenon headlamps with the Intelligent Light System and LED daytime driving lights, LED technology for all the rear lights, 17-inch light-alloy wheels in a five twin-spoke design, a special, lowered suspension setup, ambient lighting and the instrument cluster in a sporty tubular design. This model variant is also distinguishable by its different bumper design and a chrome-plated radiator grille with three glossy, black louvres.

Equipment packages: extras for the discerning customer

In addition to the design and equipment lines, the AMGsports package and the Exclusive package offer more scope for equipping the new E-Class to personal taste. These packages contain high-quality features that are mostly not available in isolation.

In the AMG sports packagethey include bumpers and side skirts in an AMGdesign, sport seats with enhanced lateral support, contrasting decorative seams in the seats and armrests, a three-spoke sports steering wheel with shift paddles, a black roof lining, a lowered sports suspension , perforated disc brakes with the Mercedes logo and 18-inch light-alloy wheels in an AMGdesign.

The Exclusive package includes a wood/leather steering wheel, the roof lining, pillar claddings and sun visors in Alcantara, the seat upholstery, armrest and door panels in nappa leather, an attractively lined dashboard with decorative seams and velours floor mats.

Market position: With ten million models since 60 years the world’s most successful business saloon

The new E-Class saloon is the successor to a Mercedes model that has been successful throughout the world, and of which more than 1.3 million examples have been sold since 2002. In Germany more than 40 percent of all saloons in this market segment have an “E”in their model plate, and in many western European countries this Mercedes model series is the number one in the luxury class.Since 1947, when the Model 170 V was introduced as the direct ancestor to the E-Class, Mercedes-Benz has produced more than ten million saloons belonging to this series. This makes the E-Class easily the world’s most successful business saloon.

The new E-Class will appear in the showrooms of the European Mercedes sales and service outlets and dealerships in March 2009.

At the 2009 Geneva Motor Show, Mercedes-Benz is presenting a new, eye-catching special model in the successful SLK series with the model suffix “2LOOK Edition”. This new model variant, which is specifically aimed at a younger target group, is only available in glossy black or lustrous white. This styling touch is harmoniously complemented by a two-tone interior with high-grade materials in dramatic black-and-white contrasts.

The attraction of opposites – this is the concept with which the new Mercedes-Benz SLK “2LOOK Edition” special model will enter the new open-top season. The intentional limitation to a black-and-white colour scheme both inside and out lends this successful two-seater with a vario-roof an exclusive, dramatic appearance and ensures a decidedly eye-catching presence.

The SLK 2LOOKEdition is painted in a choice of either calcite white or black as standard. On request the SLK 2LOOKEdition is also available in exclusive obsidian black metallic or the special finish designo mystic white, which is limited to 300 vehicles worldwide. Headlamps with black surrounds send an additional stylish message, ensuring that the SLK 2LOOKEdition is easily recognisable from a distance.

The sporty and striking appearance of the special model is emphasised by 18‑inch 5-twin-spoke light-alloy wheels with mixed tyre sizes (front: 225/40 R18, rear: 245/35 R18). In line with the colour philosophy of the 2LOOKEdition, these are available in two surface variants: a lustrous high-sheen finish in titanium silver or dark, striking chrome shadow. Discreet emblems on the wings and a draught-stop of transparent acrylic glass from the range of high-quality Mercedes accessories bearing the 2LOOKEdition logo also distinguish the special model.

Attractive antithesis – interior in black and white

A contrasting black-and-white colour scheme also characterises the interior of the new SLK 2LOOK Edition. The sports seats are upholstered in nappa leather – with the seat centre panels in white and the contoured bolsters in black. The doors and centre armrest are also in a contrasting black-and-white scheme in high-grade leather. Eye-catching, carefully finished decorative seams on all leather surfaces accentuate the dramatic character of this special edition.

Black-and-white features throughout the vehicle underline its dynamic potential: the multifunction steering wheel in black nappa leather with a white decorative seam, the white-painted trim in the black dashboard and – when the roof is closed – the black roof lining. The white-edged floor mats have an embroidered Edition label.

The SLK 2LOOK Edition can be ordered with immediate effect in the engine variants SLK 200 KOMPRESSOR, SLK 300 and SLK 350 Sports Engine. The extra cost of this special model is 2100 euros. The special paint finishes cost an additional 580 euros for obsidian black metallic and 1990 euros for the limited edition in designo mystic white (German list prices incl. VAT).

As the Geneva Motor Show gets set to open its doors to the press tomorrow, Mercedes has taken a moment to reveal details a model that won’t be in attendance – one that’s being officially called the Mercedes-Benz SLS AMG. Strangely enough, it sounds a little like a Cadillac model… oh wait, it is a Cadillac model. Nevertheless, that is the name of the vehicle that up until now has been known as the Mercedes SLC, or less formally, the new Mercedes Gullwing.

So what can we expect from the new Caddy Mercedes? Pretty much exactly what was already rumored to be in place. Power comes from a revised version of AMG’s 6.2-Liter V8, with output coming in at 563 hp at 6800 rpm and 479 lb-ft of torque at 4750 rpm. Revisions to the engine include a new magnesium intake with eight separate velocity stacks, two electronically controlled throttle plates to feed the new intake, a new dry-sump system to lubricate the engine, and a lowered position behind the front axle allowing a claimed 48 percent/52 percent front/rear weight distribution.

Also in place will be a new seven-speed transaxle gearbox, as opposed to the one currently utilized on the SL63 AMG. Mounted at the rear axle and encompassing the differential, the new gearbox is a dual-clutch automated manual transmission – one that that will shift gears by itself or at the driver’s command. Connecting the engine to the rear-mounted transaxle is a torque tube housing a lightweight carbon-fiber composite driveshaft, just one of the various components that help the SLS achieve a curb weight of 3,571 lbs (that’s nearly 300 lbs lighter than the SLR McLaren). The end result when mated with the AMG 6.3-Liter V8 is a 0-62 mph time of 3.8 seconds, while top speed comes in at 196 mph.

There’s no word yet on pricing for the model, although early reports indicate the Mercedes SLS AMG will likely be in the $250,000 range. We’ll keep you posted as new details are revealed; in the meantime, keep scrolling to see a few additional photos and diagrams outlining the Mercedes SLS AMG Gullwing (click any to enlarge), then head over to Car and Driver for their full report and photo gallery.

When the 79th Geneva Motor Show opens its doors in a little over a week from now, another model making its debut will be a special edition of the lovable smart fortwo micro hybrid drive (mhd) – one the company is calling the smart fortwo “edition limited three.” A picture of spring, the fortwo limited edition three is based on the passion equipment line, and comes standard with melon green metallic paintwork and a host of practical options. Highlights include 15-inch alloy wheels in a six-spoke design, softouch automatic gear program, electric windows, air conditioning with automatic temperature control, dashboard instruments and the radio 9.

Inside, the smart fortwo limited edition three’s spring design theme continues, as the seats and door trim feature exclusive fabric in varying shades of brown – a color that matches perfectly the outward melon green paintwork. Further adding to the model’s unique style, the instrument panel features dark brown leather-effect details as does the 3-spoke steering wheel and gearshift (the latter two of which feature real leather), while completing the interior are matte silver trim parts throughout.

If you’re interested, the smart fortwo limited edition three will be available as both coupe and cabrio versions with the 52kW /71 hp powerplant you’ve all come to know and love. Pricing for the coupe fortwo comes in at €15,470, while the cabrio will set you back €18,510 (both German list prices incl. VAT).

Welcome back ladies and gentlemen; I hope you all had a fantastic weekend. We didn’t quite find the time you bring this article last week, but we felt this article was worth a mention even late, because let’s be honest: who doesn’t love reading about a 228,500 euro two-tone GL-Class? I know I do, so here for your viewing pleasure is the Carlsson Aigner CK55 RS Rascasse, a limited edition Mercedes GL500 developed by Mercedes tuning firm Carlsson and the luxury leather brand Etienne Aigner AG.

According to Carlsson, “the star qualities of this car are obvious at a glance.” First and foremost, there’s the paintwork, consisting of several coats of hand-rubbed wine-red metallic paint applied below the window line accented by black on the upper half of the model. Furthermore, there’s a complete Carlsson body kit present, ranging from wider wheel arches, new side skirts and a new front and rear apron all the up to a new bonnet with integrated power domes. And the grille – let’s not forget that big mesh, Chevy-looking grille.

So what else does 228,500 euros get you? More power, courtesy of Carlsson’s engine conversion system for Mercedes’ 5,461cc, 48-valve, DOHC V8. As a result, the Carlsson Aigner CK55 RS Rascasse boasts a total output of 456 hp (335 kW) with 640Nm of torque, enough to propel the model from 0-62 mph in 5.9 seconds (compared to 6.5 seconds for a traditional GL500).

And last but not least, being a collaboration between Carlsson and a luxury leather brand, there’s bound to be a fantastically ostentatious interior, and judging by its description, it sounds like the Aigner CK55 RS Rascasse will fail to disappoint. According to Carlsson, the SUV uses only the finest hides and Alcantara to cover the seats, dashtop, door panels and center console, all of which feature the dark shade of red found on the model’s exterior. Ensuring the optimum in drinking while backseat driving, an integrated fridge has been added, while the removal of three of the model’s rear seats (leaving two individual passenger seats) ensures you’ll have plenty of space to get your swerve on.

If you’re interested, as already noted, flamboyance isn’t cheap, as the Carlsson Aigner CK55 RS Rascasse will set you back EUR 228,000 and change. Only 20 are set for production, however, so if you want one, you better act quick.

After seemingly countless spy photos showcasing the model nearly undisguised, today Mercedes has finally taken the wraps off their new E-Class Coupe, and it looks pretty much exactly as we expected it to. From a design standpoint, if you’re a fan of the new E-Class saloon, chances are you’re going to be a fan of the coupe range as well. Featuring similar styling traits to that of the sedan, the two are clearly members of the same family, although the Coupe offers customers a more contemporary take on the same elements. In the front, for example, the twin-headlamp face with rhomboid headlamps is still present, but with a sharper, somewhat sportier look. Also present is a twin-louvre grille with a larger center Mercedes star. In the back, the contour of the rear wing reminiscent of the Ponton Mercedes of yesteryear is still a prominent feature, while the elongated taillights again bear a similar appearance to the taillights found on the sedan.

Under the hood, initially there will be five variants of the Mercedes E-Class Coupe:

the E250 CDI BlueEFFICIENCY (150 kW/204 hp)

the E350 CDI BlueEFFICIENCY (170 kW/231 hp)

the E250 CGI BlueEFFICIENCY (150 kW/204 hp)

the E350 CGI BlueEFFICIENCY (215 kW/292 hp)

the E500 (285 kW/388 hp)

In addition to consuming up to 17 percent less fuel than prior comparable variants thanks to the use of new engine technology, the BlueEFFICIENCY models also boast a number of further practical fuel saving measures, including on-demand steering and fuel pumps; tires with low rolling resistance; an alternator control system that varies vehicle power based on demand; and last but not least, improved aerodynamics.

And finally, what new Mercedes would be complete without a raft of new safety features and driver assistance systems, and the E-Class Coupe is no exception to the rule. Selective damper control, ATTENTION ASSIST, PRE-SAFE, Adaptive Main Beam Assist, Brake Assist Plus and PRE-SAFE Brake can all be had on the Coupe, easily placing it atop its segment in the safety category.

As for when you can get your hands on one, the Mercedes E-Class Coupe will debut at the Geneva Motor Show next month, and can be ordered from February 19th onward. Deliveries in Europe will commence in May 2009, with pricing in Germany (including 19% VAT) ranging from EUR 44,684.50 for the E250 CDI and E250 CGI models up to EUR 66,045.00 for the E500.

It is now 30 years since production of the Mercedes-Benz G-Class began. The Stuttgart-based car maker first unveiled this robust off-roader to the public in 1979, since when it has delivered a total of some 200,000 units of the G-Class to customers around the world. Its still striking appearance, which has remained substantially unchanged throughout its 30-year career, plus outstanding engineering, has secured this Mercedes-Benz off-roader cult status in the automotive world, and made it one of the most coveted vehicles of its type on the market.

This model family, which is acknowledged to be the best in the off-road sector, bears the succinct “G” prefix in addition to the Mercedes star, has won the Paris-Dakar Rally, is a means of transport considered fitting for the Holy Father, has become an automotive styling icon, continues to emerge victorious in reader votes and represents the gene pool for the Mercedes-Benz SUV family, which has meanwhile grown to five model series. And that is not all: with a production life of 30 years, the “G” is easily the longest-serving passenger car series in the more than 120-year history of Mercedes-Benz. Continuous model updates keep the G-Class up to the latest technological development status and guarantee a superior drive system, but without diluting its essential character. Thanks to a combination of permanent all-wheel drive, the electronically controlled traction system 4ETS, ESP®, a “low-range” gearbox and three selectable differential locks, the G-Class is equal to any off-road challenge while ensuring the handling safety expected of a Mercedes on the road.

Last year too, both the comfort-oriented 463 series and the utility-oriented 461 series of the G-Class held their own outstandingly throughout the world. There are currently no plans to bring this success story spanning three decades to an end.

Dr. Dieter Zetsche, Chairman of Daimler AG: “We have sold 200,000 examples of the “G” to date. The vehicle is now more successful than ever, and the customers are more enthusiastic than ever. Perhaps we will be celebrating yet another major anniversary in ten years time.”

The unending story begins in 1972

The development of an off-road vehicle began in 1972, with a cooperation agreement between Daimler-Benz and Steyr-Daimler-Puch in Graz, Austria. In 1975 the decision was taken to commence series production and construct new production facilities in Graz, where the G-Class is still mainly hand-assembled to this day. When the series was premiered in spring 1979, four engine variants were available with outputs from 53 kW/72 hp to 110 kW/150 hp, either as a Convertible with a short wheelbase or a Station Wagon with a short or long wheelbase. After continuous model facelifts and further development during the first ten years, a major development step was taken in 1989, when the G-family had offspring. As an addition to the revised original model with the in-house series designation 460, which was in future to be destined mainly for utility-oriented users, the range was extended with the 463-series models. With new, permanent all-wheel drive, differential locks at the front and rear axles, which now became standard equipment, and a fully lockable inter-axle differential, these marked a new technical departure. ABS also became available as an optional extra. The completely redesigned interior impressed with new comfort features such as new seats, interior body panels, a centre console, a new dashboard and exotic wood trim.

Since September 2001 the G-Class has also featured the trailblazing handling stability, traction and braking control systems ESP®, 4ETS and Brake Assist.

A full range: the current G-Class

The current model family is available in three body variants (short-wheelbase Station Wagon, long-wheelbase Station Wagon, Convertible), which can be combined with either the economical V6 CDI engine developing 165 kW/224 hp and 540 newton metres, or a powerful 5.5-litre V8 petrol engine with 285 kW/ 388 hp and 530 newton metres. The top-of-the-range G 55 AMG, which is available only as a four-door, long-wheelbase Station Wagon, has a supercharged V8-engine generating an output of 373 kW/507 hp and an impressive maximum torque of 700 newton metres. The result is shattering performance that goes together with an incomparable sound to characterise this particularly sporty version.

Another important model in the range is the G-Guard, which is based on the long-wheelbase G 500 Station Wagon. This fully-armoured special protection G-Class is certificated to protection class B6 or B7 against attacks with handguns, longarms and explosive charges of defined size.

G-Class EDITION30 and G-Class EDITION30.PUR: Spectacular special models to mark the anniversary

The fact that the G-Class was designed for operations in the most difficult terrain right from the start is made particularly clear by the special EDITION30. PUR model based on the G 280 CDIfrom the G 461 series. This long-wheelbase Station Wagon pays homage to the first-generation G-Model, has been optimised specifically for the toughest assignments off the beaten track and is therefore the future dream car for world travellers, expedition leaders, confirmed fans of the “G” and customers who are in search of an automotive rarity with uncompromising reliability and the ability to go anywhere. With the optional “Off-road package 1” or “Off-road package 2”, the G EDITION30.PUR can e.g. be equipped for any eventuality with all-terrain tyres in size 265/75 R 16 on aluminium wheels, flexible wheel arch flaring, protective grilles for the headlamps and lights, a walk-on bonnet for easier access to the optional roofrack, a towing lug at the front and a two-section rear door. In the interior there are four individual seats upholstered in hard-wearing fabric or man-made leather, rubber floor coverings in the passenger compartment, spray-protected controls and drainage apertures in the footwells. A load compartment with a wooden floor, load lashing lugs and rails is standard, as are an auxiliary heater and manually operated air conditioning to cope with any climatic zone encountered.

With the special EDITION30 model based on the G 463 series, Mercedes-Benz is once again demonstrating the possibilities of the G-Class with respect to comfort and prestige. Externally, this long-wheelbase G 500 Station Wagon is distinguished by a designo platinum black paint finish, specially designed light-alloy wheels and EDITION30 lettering on the wings. The interior of this G 500 impresses with designo leather in the colour “chablis” and designo trim in anthracite poplar wood.

The two special models can be ordered from mid-February 2009. The “EDITION30.PUR” from the 461 series costs from 59,381 Euro incl. VAT, while the “EDITION30” based on the long-wheelbase G 500 Station Wagon is priced from 97,461 Euro incl. VAT.

For the fifth time in succession, the Mercedes-Benz Unimog has been voted the best off-road vehicle of the year in the “special-purpose vehicles” category by readers of the special-interest magazine OFF ROAD. The “Off-roader of the Year 2009 – Special-purpose vehicles category” award was made on the basis of a vote covering vehicles in eight categories in the December edition of this venerable Munich-based off-roader magazine. The OFF ROAD obelisk was recently presented during a ceremonial gala evening at the Munich theatre pavilion “Das Schloss”. More than 44,000 readers took part in the vote between the 92 vehicles concerned. The Unimog won first place in the special-purpose category with an outstanding 42.3 % of the votes.

The categories for the readers’ vote were “Off-road vehicles”, “Luxury off-road vehicles”, “Sports Utility Vehicles (SUVs)”, “Luxury SUVs”, “Classics”, “Pick-ups”, “Special-purpose vehicles” and “Crossovers”. The Unimog was clearly ahead of the field among the special-purpose vehicles – off-road capable vehicles used to carry loads and goods to remote areas, or as a platform for special-purpose bodies such as firefighting, expedition and military vehicles. Characteristic product attributes such as outstanding off-road capabilities with portal axles, and enormous torsional flexibility combined with great robustness and solidity, were particularly praised.

The all-terrain Unimog series U 3000 to U 5000, which has been produced in Wörth since autumn 2002, is ideal for difficult off-road assignments well away from the beaten track and road. Its main areas of application are with the firefighting services – especially for forest fires – disaster relief services, expedi tions and servicing/maintenance work in areas where access is difficult. Accordingly the Unimog models U 3000, U 4000 and U 5000 ideally complement the vehicles in the U 300 to U 500 series – off-road-capable implement carriers which are mainly encountered working in the municipal services, with municipal contractors, in the construction and energy sectors, in in-company transport and in dual (road/rail) operations. The youngest addition to the Unimog family is the compact Unimog U 20, launched in 2008.

The magazine OFF-ROADhas held its Off-roader of the Year readers’ vote since 1982.

If you’re a resident of Canada considering the purchase of a new Mercedes GLK, Mercedes-Benz Canada has just launched a new microsite dedicated to the model aimed at making your purchasing decision a little easier. As is the case with other GLK microsites, features at your disposal include photos, videos, various technical specifications and an eBrochure, all presented in a highly stylized package.

Commenting on the new GLK microsite, Mark Forsyth, Manager of Interactive Marketing and CRM at Mercedes-Benz Canada, notes: “A key objective of the site was to provide prospective customers with an emotional connection to the GLK, as well as to celebrate the style and uniqueness that the vehicle clearly possesses. This is one of our hippest and edgiest vehicles to date and we wanted to offer an experience that echoes the values of this demographic.”

To see Mercedes-Benz Canada’s GLK microsite for yourself, you can do so by visiting Mercedes-Benz.ca/GLK.

While as of late, some of you may spend your time worrying about trivial things, such as the fact that the value of what you once considered to be a well diversified portfolio has since evaporated into seemingly thin air, the truth of the matter is that for some, the word recession simply isn’t part of their vocabulary. Of course, it may have something to do with the fact that the money that you thought you once had somehow managed to migrate into their pockets, but let’s forget about that, shall we? For this group of recession-proof individuals, it’s time to shop, because let’s be honest – what else is there to do after running your multi-billion dollar corporation into the ground and taking a lucrative compensation package?

To you, my greedy elitist friends, may I present the Maybach Zeppelin – a reincarnation of the classic Maybach Zeppelin that’s set to debut at the Geneva Motor Show this March. It’s features are abundant. Built on either the Maybach 57 S or the long-wheelbase 62 S, the Maybach Zeppelin is the most powerful Maybach built. In both lengths, the Zeppelin is powered by a 6.0 litre V12 biturbo engine, which now delivers 471 kW/640 hp (an additional 28 hp) and a peak torque of 1000 Newton metres.

Outside, features include a unique two-tone paint scheme in “Rocky Mountains light brown” and “Taiga black” (other colors are available as well), while inside, a “California beige” leather interior is present accented by “Stromboli black” elements and piano lacquer finish on the trim. But what makes the Maybach Zeppelin truly revolutionary is the addition of something that up until now we’ve only seen in the finest of restrooms – an air freshener. Wait a second, let me take that back. It’s not an air freshener, it’s a “perfume atomiser.” Yes, ladies and gentlemen, a perfume atomiser. I’ll let the press release take it from here:

“Customers are also able to opt for an especially refined equipment detail that is exclusive to the Maybach Zeppelin – an imaginatively designed, extremely high-quality perfume atomiser, the only one of its kind in the world. It easily eclipses all previous efforts to produce something similar, both in terms of its visual appeal and its operation. Its sophisticated technology and premium fragrances, which can be individually chosen, create a unique aromatic experience in the Maybach Zeppelin’s interior at the push of a button – stimulating the senses of the occupants not with an overpowering perfume but with a soft, delicate scent.

The system’s core component is an internally illuminated Plexiglass sphere on the rear centre console, into which Maybach Zeppelin owners can insert a vial of their preferred fragrance. A regulator pump then directs a gentle flow of air into the Plexiglass sphere, fanning the vial’s perfume molecules into the vehicle interior.”

If that’s not the pinnacle of pure frivolity, I don’t know what is.

Thankfully, the Maybach Zeppelin is a relative bargain in relation to the tens of millions shelled out in compensation to the various ex-executives across this great land of ours. Coming in at €406,000 for the Maybach 57 Zeppelin and €473,200 for the Maybach 62 Zeppelin, each of these former CEO’s can still rest easy knowing there’s still plenty of cash left over for 20,000 sq. ft. beach cottages, NY penthouses overlooking Central Park and high priced hookers.

For more info regarding the Maybach Zeppelin, keep reading for photos (click to enlarge) and the official press release.
