Preventing traffic accidents is at the heart of Mercedes-Benz’s commitment to safety. This is why the engineers in Sindelfingen are dedicated to advancing the development of sophisticated assistance systems which warn and assist the driver in critical driving situations and can act autonomously if there is acute danger. ABS, ESP® and BAS (Brake Assist) were the first technologies of this kind; their positive effect has since been confirmed by an analysis conducted by the Mercedes Accident Research department based on anonymous data samples from the German Federal Statistical Office.

The new or modified driver assistance systems in the E-Class Cabriolet are based on state-of-the-art radar and sensor technology. They have been developed to help reduce the number of accidents caused by being too close to the vehicle in front, drowsiness and darkness.

Preventive protection measures: PRE-SAFE® now also includes AIRCAP

In the new E-Class Cabriolet, occupant protection actually begins in the phase leading up to a possible accident thanks to the Mercedes-Benz PRE-SAFE® invention, which is specified as standard for the two-door model. In the event of critical driving situations with a high risk of an accident, the system activates protective measures as a precaution, allowing the seat belts and airbags to deploy with maximum effect in the event of any subsequent collision. This early accident detection is possible because PRE-SAFE® is an intelligent synergy of active and passive safety. It is linked to Brake Assist and the Electronic Stability Program (ESP®), for example, whose sensors can detect critical driving situations and send the relevant information to the electronic control units within a matter of milliseconds. PRE-SAFE® also uses these sensor data.

Anticipatory occupant protection can be activated in the event of emergency braking or critical lateral acceleration as well as when imminent danger is detected by the sensors of the assistance systems alone. The AIRCAP® automatic draught-stop is likewise integrated into the PRE-SAFE® system. If the system detects a risk of roll-over, AIRCAP® is retracted as a precaution.

Passive safety

First Mercedes-Benz Cabriolet with headbags
·

• Exemplary occupant protection with sophisticated restraint systems
• Robust rear roll-over bars triggered by pyrotechnic means

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 Cabriolet 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, for the first time in a Mercedes-Benz Cabriolet, headbags.

Whereas windowbags are used in cars with a conventional, fixed roof, mostly housed in the roof frame, the Mercedes-Benz safety specialists naturally had to employ a different airbag as well as choose a different installation position in the case of the E-Class Cabriolet. Here headbags are integrated into the door panelling in the beltline area. Covering a wide area – around 0.7 x 0.5 metres with a volume of 17 litres when deployed – the airbags provide extremely effective protection for occupants large and small in the event of a crash. The side protection system – comprising headbag and thoraxbag – optimises the level of protection afforded to individual parts of the body. Rear sidebags are available as an option.

Exemplary safety combined with maximum comfort is the best way to describe the restraint systems in the E-Class Cabriolet. When front passengers get into the car and close the doors, the seat belts are extended towards them by means of belt feeders – a Mercedes-Benz hallmark – making the belts extremely easy to put on. Once the rear passengers have taken their seats and belted up, the rear head restraints are raised from their recessed rest position to the driving position automatically. If only the front seats of the Cabriolet are occupied, there is always excellent rear visibility, while any rear passengers on board benefit from the protective effect of the head restraints in the event of a crash, providing they are wearing their seat belts.

What’s more, the geometry of the front seat belts has been optimised. The belt straps no longer run horizontally but, instead, are turned 35 degrees towards the occupants’ shoulders. The advantage of this modification is that the wind pressure on the outside of the belt strap prevents annoying belt flapping when driving with the roof down. This dreaded “shoulder-knocking” effect has been reduced substantially at speeds of up to 120 km/h.

Robust roll-over bars triggered by pyrotechnic means

Further safety features for the open-top two-door model include the A-pillars reinforced by two additional tubes, the plug-in B-pillars and roll-over protection. The latter consists of two robust bars, each with a diameter of 35 mm, which are housed in the rear head restraints in modules behind the rear seat backrests. If the sensors housed in the airbag control unit detect imminent danger to the occupants, pre-tensioned pressure springs are activated by pyrotechnic means, i.e. extremely quickly.

Consequently, both roll-over bars in the rear head restraints are extended. They reach their highest point and are locked automatically within a fraction of a second. In combination with the robust A-pillars, each of which is reinforced with two high-strength steel tubes, the steel bars provide highly effective roll-over protection.

Under the microscope

To be on the safe side: over three dozen different crash tests

Safety pioneer Mercedes-Benz has been conducting routine crash tests on complete vehicles since the late 1950s. Béla Barényi established systematic safety testing. The first crash tests were spectacular, with cable winches or steam rockets being used to propel the cars. Today the cars are accelerated by a hydraulic catapult.

The number of different crash tests has risen dramatically over the years because, in keeping with its holistic “Real Life Safety” approach, Mercedes-Benz does not only perform crash tests using those crash configurations that are specified for rating tests and world-wide approval. It also conducts crash tests based on the in-house accident research department’s findings, whose requirements sometimes go way beyond those of the statutory requirements. New Mercedes passenger cars therefore have to pass a total of over three dozen different crash tests. Currently, some 500 crash tests per year take place at the Mercedes safety centre in Sindelfingen, plus more than 50,000 computer-simulated tests.

One of the most demanding in-house crash tests is the roof-drop test, which Mercedes-Benz uses to check the body’s roll-over protection. The new E-Class Cabriolet also had to pass the roof-drop test with extreme load on the roof frame. Here the body is dropped onto its roof at a slight angle from a height of 50 centimetres. Consequently, the vehicle lands with its full weight on one of the two A-pillars, which is only allowed to deform slightly if the vehicle is to pass the tes

What Car?, the UK’s biggest car buyer’s guide, has named Mercedes-Benz the winner of its 2010 prize for best safety innovation for the ATTENTION ASSIST feature, which is designed to combat overtiredness in drivers – one of the most frequent causes of accidents. The Mercedes-Benz S-Class also took home the Car of the Year Award for best buy in the luxury segment for the fourth time in succession.

The most important source of independent information for car buyers in the UK, found Mercedes-Benz’s ATTENTION ASSIST feature exceptionally clever and presented the Stuttgart-based carmaker with its 2010 Car of the Year Safety Award as a result. During a test, British consumer testers were shocked by how drivers almost imperceptibly have difficulty keeping the vehicle on track when they are overtired. In practical trials, the innovative ATTENTION ASSIST driver support system was found to help combat this problem.

Like in Germany, driver fatigue is one of the most common causes of accidents in the UK. Overtiredness is a factor in a quarter of all motorway accidents. ATTENTION ASSIST, which comes as standard on all new Mercedes-Benz E-Class models, monitors over 70 parameters relating to driving behaviour to recognise when a driver is tired. If the system detects signs of fatigue, it warns the driver to take a break by means of an audible signal and a message on the display in the instrument cluster.

Other active safety features on the E-Class include Adaptive Highbeam Assist, Lane Keeping Assist, Blind Spot Assist, Speed Limit Assist, the PRE-SAFE® Brake which initiates partial or emergency braking automatically if there is an acute risk of a head-to-tail collision, and DISTRONIC PLUS proximity control.

These driver assistance systems are also available on the Mercedes-Benz S-Class, setting the standard in the luxury class. This year the UK’s consumer organisation for car buyers, What Car?, acknowledged the S-Class’s special position and again awarded the top model from Stuttgart its Car of the Year award in the luxury class for the fourth time in a row.

The ESF 2009 is the first Experimental Safety Vehicle Mercedes-Benz has built since 1974. Like its historic predecessors, it attractively combines trailblazing innovations in the field of safety and makes the progress achieved visible. Integrating all the ideas and implementing them for a clear appreciation was an extraordinary challenge for the team in the test vehicle workshops.

The go-ahead for the ESF was given in October 2008, and the decision was received with great enthusiasm in the test workshop: “Making safety visible – I was quickly able to assemble a highly qualified team for this interesting project”, says Axel Wittig, the team leader for the entire workshop facility. “The complexity of this assignment was a welcome challenge, as we not only had to integrate the numerous innovations into an S 400 HYBRID, but also make them fully functioning in demonstration mode and provide a look behind the technical scenes by incorporating eight inspection windows in the bonnet, bumpers and doors.”

The core workshop team for the ESF 2009, headed by coordinator and facilitator Hans Peter Hiller, consisted of three model-builders and two electricians. The team was supported by Jürgen Arnold, who took care of the electrical engineering, and designer Matthias Rissmann, who e.g. prepared the body apertures for the inspection windows. It was only possible to keep to the ambitious time-plan because countless internal (from the upholstery specialists in Design to production engineering) and external suppliers gave rapid and unbureaucratic assistance. “The great enthusiasm for the core Mercedes expertise of safety could be felt at all times”, project manager Michael Fehring remembers: “The ‘Daimler spirit’ ensured rapid decisions without time-consuming consultation processes.” Sheer fascination for technology also played an important part. The chance to take a look into a radar sensor, which is normally only supplied as a ‘black box’ but was in this case integrated into the front bumper in a cutaway state, attracted many an engineer who was not involved in the project into the workshop bay for the ESF 2009.

The complexity of this project, which involved the integration of 13 safety innovations into the hybrid version of the S-Class that only existed as a prototype when the work started, is already shown by the fact that a completely new wiring harness had to be designed and produced. At the heart of the demonstration technology is a divided compressed air tank in the boot, with a compressor and external power supply, which provides the airbags and the air chambers for PRE-SAFE Pulse and Interseat Protection with air. The finishing touch for the ESF 2009 is a central remote control system for all the functioning demonstrations.

The result of all this work was two experimental vehicles in the special ESF paint finish, which includes black-painted chrome trim and reflective strips on the door seals and tyres: the actual ESF 2009 and its externally identical brother, which can be used for driving and photographic purposes.

Interview with Prof. Dr. Ing. Rodolfo Schöneburg, Head of Safety Development, Mercedes-Benz Cars.

Prof. Dr. Ing. Rodolfo Schöneburg was born on 30 October 1959, studied aerospace engineering and obtained his doctorate at the Technical University of Berlin. He holds an honorary professorship at the College of Technologyand Business Economics (HTW) in Dresden. He has been active as the head of the centre for safety/vehicle functions at Mercedes-Benz since April 1999. It was under his aegis that the preventive occupant protection system PRE-SAFE®entered series production in 2002, with which Mercedes-Benz started a new era in vehicle safety. Here are some of Prof. Schöneburg’s comments on the ESF 2009 experimental safety vehicle.

Question: Prof. Schöneburg, during the period from 1971 to 1974 Mercedes-Benz presented four Experimental Safety Vehicles (ESFs) to the public. Then there was silence. Why?

Prof. Schöneburg: At the end of the 60s, vehicle safety suddenly became a focus of public attention. In 1969 the Mercedes-Benz Safety Centerwas founded in Sindelfingen. Numerous developments were initiated, ranging from active safety with ABS and ESP® to fundamental improvements in vehicle structures and innovative restraint systems such as the airbag. All of these were tested and presented in our ESFs, and from the mid-70s more and more of these innovations reached series production maturity. Accordingly they were subsequently presented with the launch of new series production models.

Question: So why are you presenting another research vehicle now, the ESF 2009?

Prof. Schöneburg: Both in-house and externally, the large number of safety features that we already have in our series production cars has created the impression that we do not have much more to offer in this respect. This impression is quite wrong – we have a wealth of ideas on how safety might be improved still further. Some of these can be realised within a relatively short time, for example PRE-SAFE® for rear-end collisions. Other concepts like the inflatable metal sections in PRE-SAFE Structure lie well in the future. And with Interactive Vehicle Communication we are only just starting to develop a completely new field. The ESF 2009 comprehensively offers up all these perspectives. Moreover, our intention was to send out certain signals for the ESV Conference, which is being held in Stuttgart for the first time since 1971.

Question: What is particularly special about the ESF 2009?

Prof. Schöneburg: As with the ESFs of the 1970s, this is a comprehensive embodiment of our safety philosophy. The primary aim is to prevent accidents in the first place. Where this is not possible, the aim is to mitigate their effects. Moreover, we want to approach both of these goals without increasing the vehicle’s weight, restricting its practicality or compromising the autonomy of the driver. He or she bears the final responsibility – and the car should provide support in the process.

Question: What new ideas have been incorporated into the ESF 2009 to prevent accidents where possible?

Prof. Schöneburg: These start with the concept of “seeing and being seen”. The LED headlamps of the ESF2009 not only illuminate the road further and more efficiently, but also ensure that other detected road users are not dazzled in the process. The Spotlight function is something quite new: it precisely pinpoints obstacles or objects that have been recognised by the infrared Nightvision camera. Thanks to new reflective strips on the sides, which leave the body design unaffected during daytime, the ESF 2009 is also much more easily visible to other road users in the dark. One technology which we think has tremendous potential for the next few years and decades is car-to-car communication. This makes it possible to warn drivers of hazards on their route as the situation requires.

Question: In addition to highly developed restraint systems, Mercedes cars with PRE-SAFE ® have a preventive safety system that can recognise an impending accident and mitigate its effects with numerous actions right up to automatic emergency braking. Is it still possible to make significant improvements to this already high standard?

Prof. Schöneburg: Yes indeed. The basis for PRE-SAFE®is a network of onboard sensors and systems, and this is where we still have plenty of ideas for further developments. Take side impacts as an example: with the help of air chambers in the seats, it would be possible to move the passengers away from the danger zone to some extent. We have already spoken about improvements where rear-end collisions are concerned. And the Braking Bag is a completely new approach to scrubbing off energy before an impact occurs.

Question: At first glance this is a crazy idea – using an airbag under the car to force a high-friction coating against the road surface as an auxiliary brake…

Prof. Schöneburg: …certainly unusual, but by no means crazy. Initial trials of the principle have shown this idea to have considerable potential. In the next few years we intend to research and develop this potential further.

Yesterday we brought word of a new concept vehicle based on the new Mercedes S400 Hybrid, and today, Daimler has officially unveiled the model along with a lengthy description.  It’s called the Mercedes-Benz ESF 2009 Experimental Safety Vehicle, and it’s the first safety vehicle to be built by the company since 1974.  In total, the Mercedes ESF 2009 features more than twelve safety systems, the majority of which are fully functioning.

According to Dr. Dieter Zetsche, Chairman of Daimler AG and CEO of Mercedes-Benz Cars:  “Safety is a central element of the Mercedes-Benz brand. In this respect we have been setting the pace in the market for almost 70 years. For the benefit of our customers and for road users in general. The ESF 2009 shows that we still have plenty of ideas and the absolute will, to lead the automobile industry in this field even in future.”

To detail the model, Daimler has published a numerous part press kit and roughly 60 photos, so rather than attempt to paraphrase the exceptionally lengthy content, I’m going to let the press material take it from here.  It’s truly a fascinating concept, so stay tuned to see where the future of Mercedes-Benz vehicle safety is headed.

PRE-SAFE Structure: It sounds like science-fiction – concealed metallic structures that wait patiently in a collapsed, space-saving state until they are required to go into action. Daimler researchers working together with the gas generator specialists at Autoliv spent two years actively researching such active metal support systems, and tested a variety of applications. For the very first time, inflatable metal side impact protection can be seen in the ESF 2009.

Imagine an inflatable mattress. When it is not needed, it is rolled up flat and e.g. consigned to a shelf in the attic. When inflated, however, it has a highly resistant structure that can easily carry a man weighing 100 kilograms. Inflatable metallic structures work in the same way: when not in use, the metal section is folded together to save space. Once its protective effect is needed, a gas generator just like those used to inflate airbags builds up an internal pressure of 10 to 20 bar within fractions of a second, the metal section is unfolded and the structure has significantly greater stability.

The advantages are obvious, and mainly involve packaging and weight: more stable structures can be accommodated within the increasingly tight installation spaces of an automobile, or weight can be greatly reduced while maintaining the same stability. Using the example of the side impact protection member in the doors of the S-Class, the researchers have calculated that around 500 grams less weight per door would be feasible.

Daimler safety researchers examined various applications for these innovative, crash-responsive metal structures, among them side impact protection, the side skirts and the seat cross-members. These have the advantage of being several centimetres away from the impact zone. The gas generator therefore only needs to be activated when a crash has definitely taken place.

One of the still unsolved problems of these protective members is that unlike the PRE-SAFE® measures already in series production, their active deformation is not reversible. Moreover, the activation of protective members installed well to the outside of the bodyshell that can be inflated by internal pressure requires their deployment before the crash. The pre-crash sensor system must therefore provide highly reliable signals.

Another hurdle is the currently still uncompetitive cost level of the required gas generators in relation to the cost requirements for weight-saving measures. These crash-responsive metal structures are therefore still a thing of the future – but the same was also once true of standard safety features like the airbag, ABS or ESP®.

Braking Bag: a braking parachute for the car

Airbags in cars have previously only been used as a restraint system for the occupants. In the future they might also be a PRE-CRASH- component, activating an auxiliary brake in the vehicle floor and improving both deceleration and compatibility with the other vehicle involved in the accident.

Energy is not only reducible by braking the road wheels: jet fighters and dragsters use braking parachutes, for example. And as early as 1952, Mercedes-Benz was already experimenting with an air-brake at the Le Mans race: when decelerating, the driver was able to move a metal panel on the roof of his racing SL to a vertical position. Even earlier, coachmen used special wheel chocks. These were placed in front of one of both rear wheels on long downhill gradients, and their iron-clad base helped to brake the vehicle during the descent.

This is an old idea that Mercedes safety researchers have revitalised on a similar principle with the Braking Bag, an airbag installed between the front axle carrier and the underbody panelling. If the sensor system concludes that an impact is inevitable, the PRE-SAFE® system not only initiates automatic emergency braking. At the same time the Braking Bag is deployed just before the crash, supporting the car against the road surface by means of a friction coating. The vehicle’s vertical acceleration increases the friction and has an additional braking effect before the impact. The Braking Bag uses the PRE-CRASH sensors in Mercedes-Benz cars, which are already able to initiate preventive occupant protection measures in critical driving situations.

There are several advantages to this unusual auxiliary brake:

• The rate of deceleration is briefly increased to over 20 m/sec/sec. This scrubs additional energy beyond the potentials of a wheel brake, thereby reducing accident severity.
• Because the car is raised upwards by up to eight centimetres within a short time, the dive effect that occurs with conventional brakes is substantially compensated. This improves geometrical compatibility with the other party in an accident.
• This vertical movement also improves the effects of the restraint systems: the seats move towards the occupants by around three centimetres, which enables the belt tensioners to take up more slack. The high deceleration rate before the impact has a “pretensioning” effect on the occupants, so to speak.
• Downward support for the vehicle during the crash reduces the typical diving motion during a collision.

All in all, the braking airbag has the effect of an additional crumple zone. Mercedes engineers have calculated that even at a low 50 km/h, the additional deceleration has the same effect as lengthening the front end by 180 mm. Initial driving tests in a C-Class have already shown the effectiveness of this new auxiliary brake – though it will still be some time before the Braking Bag becomes another component of the PRE-SAFE® system.

Interactive Vehicle Communication: cars report what their sensors have detected

Cars sometimes know more about their surroundings than their drivers. With the help of intelligent communication systems, vehicles themselves are able to contribute to improved road safety and mobility.

A patch of black ice on the next bend? A bank of fog three kilometres down the road? A new traffic tailback where roadworks are being carried out? What used to come as an unpleasant surprise is far less frightening if the approaching driver receives an up-to-date is warning beforehand. This is a task that will in future be carried out by the other vehicles on the roads at the time – automatically, by radio. This is the basic idea behind Interactive Vehicle Communication.

Cars are nowadays able to collect a great deal of information about the current driving situation, as the numerous sensors, cameras and control units for the dynamic and assistance systems can register e.g. poor weather conditions just as well as sudden braking and avoiding manoeuvres, or broken-down vehicles on the road. There are also other sources of information, for example local police reports. This information can be passed on via additional relay stations (“car-to-x”) such as radio masts at the roadside, stationary nodal points (e.g. traffic centres and overhead gantries) or via the internet. The onboard computer classifies all the reports according to plausibility and relevance. Tailback reports on the radio which are out-of-date or irrelevant to the individual driver will then be a thing of the past.

Mercedes engineers have been working on “Interactive Vehicle Communication” as a technology of the future for more than seven years. The ESF 2009 safety concept vehicle demonstrates the current status of this research: this Mercedes can automatically recognise an approaching police car, for example, and warn its driver by showing a symbol in the display. It is also possible to send and receive warnings of bad weather or obstacles in the road.

The exchange of data between vehicles is via so-called “ad hoc” networks, connections that are spontaneously formed between the vehicles over short distances. These wireless local area networks (WLANs) are self-organising, and require no external infrastructure. Transmission and reception is at a frequency of 5.9 gigahertz, over a distance of up to 500 metres. In fact the achievable communication range is much greater, as oncoming vehicles pass the messages on.

Cars that communicate with each other can do more than just pass on information: linked to modern proximity control systems such as DISTRONIC Plus from Mercedes-Benz, they can help to harmonise the traffic flow and avoid tailbacks by automatically selecting the most suitable vehicle speed when joining a motorway. And collisions can be avoided if onboard sensors recognise an impending accident and automatically regulate the distance.

This technology is currently demonstrating its practicality in the “Safe Intelligent Mobility – Test area Germany” project (simTD), in which Mercedes-Benz and other German manufacturers and suppliers are taking part. Up to 400 vehicles communicate with each other in these, the world’s largest field trials for Interactive Vehicle Communication. simTD is being conducted in the densely populated Frankfurt/Rhine-Main area from autumn 2008 to 2012. Experts expect usable mobile information networks with full coverage to become a possibility when around ten percent of all vehicles have this communications capability.

With the multiple award-winning PRE-SAFE® system, Mercedes-Benz has once again been underlining its role as a pioneer in the safety field since 2002: once the system recognises certain critical driving situations, PRE-SAFE® activates occupant protection measures as a precaution. As a further development, PRE-SAFE Pulse is able to reduce the loads acting on the torsos of the occupants by around one third during a side impact by preventively moving them towards the centre of the vehicle.

Out of harm’s way – every millimetre counts during an accident. When an impending lateral collision is recognised, PRE-SAFE Pulse as an active restraint system moves the driver and front passenger towards the centre of the vehicle, using air chambers in the side bolsters of the seat backrests. If the onboard sensors report that a side impact is inevitable, these are inflated within fractions of a second and give the seat occupants a slight nudge in the ribs. This impulse is enough to move them out of the danger zone by up to 50 millimetres. Even before the accident, it also accelerates the seat occupant in the direction he/she will later take during the accident. This reduces the loads acting on the occupant during the impact. The seat does not need to be replaced or repaired when this preventive safety system has been activated, as PRE-SAFE Pulse is reversible.

PRE-SAFE Pulse is being developed on the basis of the dynamic multicontour seat in the new Mercedes E-Class. Depending on the steering angle, lateral acceleration and speed, the inflation pressure and volume of the air chambers in the side bolsters of the seat backrests are already varied to give the driver and front passenger even better lateral support.

Partial main beam: full beam ahead at all times

Whether as brake lights and indicators in many Mercedes models, or as daytime driving lights in the new E and S-Class, LED lighting technology is seeing increasing use at Mercedes-Benz. And things will be brightening up at night as well in future: Mercedes lighting specialists are working on an adaptive LED main beam system that automatically excludes oncoming traffic from the cone of light. A special spotlight function also allows potential hazards to receive additional illumination.

Main beam, low beam, main beam… anybody travelling on country roads in western Europe at night is seldom able to drive with the main beams on for very long. The frequency of oncoming traffic dictates that the driver is soon obliged to switch to low beam, either manually or more conveniently using the Main Beam Assist in the new Mercedes E-Class. This is not enough to satisfy the researchers at Mercedes-Benz, however. Because during the phases when the driver switches to low beam – with its shorter range – to avoid dazzling others, it is possible to overlook other road users or potential hazards.

The lighting specialists at Mercedes-Benz are therefore working on an LED-based adaptive main beam system. This enables the driver to leave the main beams switched on constantly. As soon as the system detects oncoming traffic with the help of a camera, it automatically adjusts the light distribution accordingly. The Mercedes ESF 2009 experimental safety vehicle shows precisely how this works. A headlamp is made up of 100 LEDs. These semiconductor elements can be individually activated, so that when there is oncoming traffic, the precise beam area in which other road users are located can be darkened down. The system recognises these using an infrared camera. The purely electronic module is also able to respond much faster than present electro-mechanical shutter/roller assemblies.

The light distribution can also be refined in the opposite direction: a special spotlight function in the LED array of the research vehicle also enables potential hazards to be highlighted. If the infrared camera detects pedestrians in the road ahead, for example, they can be briefly lit up beyond the normal main beam illumination, as if by an aimed spotlight. The driver is thus alerted to the potential danger.

Side Reflect: not all Mercedes are grey at night

Reflective material on the body and tyres could further improve the lateral visibility of vehicles, and help to avoid accidents at road junctions.

Reflective materials have long been commonplace in children’s clothing, and in the case of bicycles it is even mandatory to have reflectors in the wheel spokes. So the engineers at Mercedes-Benz asked themselves why the perceptual safety of cars could not be improved in the same way. Accordingly the ESF 2009 research car features appropriate reflective elements when viewed from the side. These modifications are not visible during the daytime, but the additional benefit shows up when dusk and darkness fall.

Together with the manufacturer Continental, Mercedes specialists have developed a reflective strip on the tyres which visually enlarges the wheels in daylight and creates an easily visible band of light when illuminated at night. As a further safety feature there are reflective seals between the doors and the roof, a joint development with the adhesive foil specialist 3M. The aim is to make the vehicle’s silhouette more easily visible in the dark. This enables potential accident situations on junctions or in the form of unlit, parked vehicles to be defused.

Reflective foils consist if a reflective base layer with tiny balls of glass. When a ray of light hits the foil, it is refracted by the glass balls, reflected by the base layer and refracted again on exiting. As a result, most of the light is reflected back in its original direction.

Belt Bag: a clever combination of a seat belt and airbag

The seat belt is regarded as one of the most important inventions of the 20th Century, and has saved countless lives. It has been further improved with belt tensioners and belt force limiters, but that is not the end of its development: an innovative extension to the width of the belt, known as a Belt Bag, is able to reduce the risk of injury even further in an accident.

When a seat belt limits the movement of its wearer’s torso as intended during a collision, it subjects the body to considerable forces. The Belt Bag, on whose development Mercedes-Benz is working intensively with the seat belt specialist Autoliv, practically doubles its width within fractions of a second during an accident. This increase in the width of the belt spreads the pressure over a wider area, thereby reducing the risk of injury. This is particularly beneficial for older passengers, whose ribcage is no longer so flexible.

As the name suggests, the Belt Bag is a combination of a seat belt and airbag. When the crash sensors detect a serious impact, the airbag control unit activates the Belt Bag. A generator at the belt armature inflates the double-layered belt, which has Velcro seams. The volume of the Belt Bag is around four litres. The developers consider the Belt Bag to deliver the greatest benefits in the rear of the car, where conventional airbags cannot be installed. It is therefore conceivable that the Belt Bag could be used here by Mercedes-Benz in the foreseeable future.

Mercedes engineers have thought about how children might travel even more safely in a car. The two major advantages of the Mercedes concept study “Child Protect” over conventional child safety seats are an improved protective effect and greater comfort for the child. This is accompanied by a high level of quality and attractive visual integration of the seat into the interior of Mercedes models. This system jointly designed with the restraint system specialist Takata is suitable for children aged between three and 12 years (weight categories II and III). One special feature is its modular construction, as the height and width can be individually adapted to the child’s physical proportions.

“Child Protect” has a tubular frame construction. This design offers better support and greater rigidity than versions of moulded plastic during a side impact. The prominent side bolsters in the shoulder and head area keep the child in place and minimise body movement during an accident. At the same time they prevent the child from coming into contact with vehicle components penetrating into the interior, or with the passenger in the adjacent seat. This seat study, which is approved according to the ECE R44.04 standard, is also equipped with automatic, sensor-controlled airbag deactivation on the front passenger seat.

As an additional benefit, Mercedes engineers are considering the addition of a buggy subframe to the child seat. This would also ensure that children travel in comfort, style and safety outside the car.

Child Cam: keeping an eye on the kids

With the help of a small camera, drivers will in future be able to keep children travelling in the rear under control without taking their eyes off the road.

“Mum, Vanessa keeps pulling my hair!” “John’s seat belt isn’t properly fastened.” – Parents know that when the kids are on board, there is usually no shortage of action on the rear seats. But if the driver looks back to see what is going on, there is a risk of an accident. Accordingly Mercedes safety experts have developed “Child Cam”, a simple camera system that enables the kids to be observed without taking one’s eyes off the road.

A small camera is mounted on the roof lining behind the front seats. If required its images can be transferred to the dashboard display – not in video form, but as sequences of stills to avoid distraction. The camera position provides a slight bird’s-eye view, which allows children in rear-facing child seats to be observed more easily.

“Child Cam” also shows rear areas that are not easy for the driver to observe, e.g. the seat directly behind. And in the case of an estate car, SUV or van, it is also possible to monitor the luggage compartment. This is very useful if domestic pets are on board, for example.

PRE-SAFE 360°: full emergency braking before an impact

With the multiple award-winning PRE-SAFE® system, Mercedes-Benz has once again been underlining its role as a pioneer in the safety field since 2002: once the system recognises certain critical driving situations, PRE-SAFE® activates occupant protection measures as a precaution. As a further development, PRE-SAFE 360° monitors not only the areas to the side, but also to the rear of the vehicle.

PRE-SAFE 360° uses short-range or multi-mode sensors to monitor the area behind the vehicle to a range of up to 60 metres. If the accident early-warning system registers that a collision is unavoidable, the brakes are applied around 600 milliseconds before the impact. If the already stationary car is braked during a rear-end collision, this not only prevents secondary accidents where the car is e.g. uncontrollably shunted into a road junction or onto a pedestrian crossing. The severity of possible whiplash injuries to the occupants can also be reduced by application of the brakes, as the vehicle and therefore its occupants have less forward acceleration. The driver always has the final decision with PRE-SAFE 360°, however: if he accelerates because he is able to prevent the rear-end collision by moving forward, for example, the brakes are instantly released.

Contrary to the widely held opinion among drivers, it does not make sense to take one’s foot off the brake pedal before an impending rear-end collision. The correct action would be to apply the brakes as hard as possible, however accident research findings show that the driver of a stationary vehicle impacted from the rear is moved backwards by up to 20 centimetres. This inevitably causes his feet to slip from the pedals.

The protective effect of PRE-SAFE 360° supports that of the NECK-PRO crash-responsive head restraints, which are already standard equipment in many Mercedes model series. If the sensor system detects a rear-end collision with a defined impact severity, it releases pre-tensioned springs inside the head restraints, causing the head restraints to move forward by about 40 millimetres and upwards by 30 millimetres within a matter of milliseconds. This means that the heads of the driver and front passenger are supported at an early stage than with conventional head restraints.

Size Adaptive Airbags: tailor-made airbags

The 1980 Mercedes S-Class (W 126) was the first series production car equipped with an airbag. In the meantime airbags have firmly established themselves across all vehicle segments. Airbags have saved many human lives and reduced the severity of injuries. Mercedes safety specialists are now working on a further improvement to their protective effect by developing airbags with a variable volume.

There are already adaptive airbags at Mercedes-Benz today, for in many model series the airbags are activated in two stages depending on the assessed severity of the impact. Future generations of this restraint system will not only take accident severity into account, but adapt themselves to the individual vehicle occupants: “Size Adaptive Airbags” automatically adjust their volume to the seating position and stature of the front passenger as recognised by the sensors. For whether a small front passenger is hunched up close to the dashboard or a tall front passenger has his seat moved well back is certainly a factor in the protective effect of the airbag. The weight of the front passenger, and therefore the forces acting on the airbag during an accident, are also important.

“Size Adaptive Airbags” enable occupant contact with the airbag to be optimally timed, whatever his weight and seating position. The restraint system can therefore dampen the impact to optimum effect. This Mercedes development varies the volume on the front passenger side between 90 and 150 litres. For purposes of comparison, conventional front passenger airbags have a volume of around 120 litres.

The system uses three retaining bands with which the airbag contours are adjusted to limit the volume. The retaining bands are fitted on electrically driven spools. When the airbag is activated, only as much band length is released as the control unit has calculated on the basis of sensor data for the seating position and weight of the occupant.

Interseat Protection: don’t get too close to me

Danger not only comes from outside during an accident. In unfortunate cases even passengers wearing their seat belts can come into contact and injure each other. Interseat Protection in both seat rows helps to prevent this.

Mercedes safety specialists are presenting two proposed solutions in one with Interseat Protection: a protective system for the driver/front passenger and one for the rear-seat passengers. As a common feature of both, the occupants are physically separated from each other if the PRE-SAFE® system registers an accident. Within fractions of a second, a lattice-like airbag support structure extends from between the front seats to keep the driver and front passenger apart. A seat-mounted solution like this has the advantage that the protective barrier adapts itself to the position of the front seats.

The seat position does not need to be taken into account in the rear, therefore a protective pad located above the centre armrest is used when an accident is detected. This pad helps to prevent the two passengers in the rear from impacting each other. When the pad is at rest it can be activated as part of PRE-SAFE®. Within fractions of a second, the seat divider emerges and the two head supports are deployed.

Mercedes accident research has shown that during a side impact, and also during a rollover, the heads of the passengers move along different paths: around 50 milliseconds after the accident, the head of the person facing the impact changes the direction of its evasive movement towards the centre of the vehicle – impelled by the sidebag and head airbag. A second important finding from these analyses is that a collision between the passengers can only be avoided if the torso is supported. The protective pad of the Interseat Protection system is dimensioned accordingly.

In normal cases the protective pad in the rear is more of an innovative comfort feature: the pad is designed to be extended by the passengers at the touch of a button, when it can be used as a head and shoulder support for a comfortable sleeping position. It would also be conceivable to use the space for stowage or a cooler box, or an entertainment console.

Hybrid Battery Shield: seven-stage safety system

A drive train with hybrid technology lowers fuel consumption and CO2 emissions. At the same time this introduces high-voltage electricity and sophisticated battery systems into passenger car engineering, however. Thanks to their long experience with fuel cell technology, Mercedes development engineers are extremely well prepared for the new challenges this presents. A comprehensive, seven-stage safety concept is the result.

The challenge lay in not only complying with all the worldwide and in-house crash test requirements, but also in ensuring the greatest possible safety for the electrical components. This safety system already applies in production, includes workshop personnel during servicing and maintenance, and also takes the emergency services into account when passengers need to be recovered following an accident. The seven-stage concept in detail:

1. In the first stage all the wiring is colour-coded to eliminate confusion, and all components are marked with safety instructions. This makes the regular technical inspections easier to carry out.

2. The second stage comprises comprehensive contact protection for the entire system by means of generous insulation and newly developed, dedicated connectors.

3. As part of the third stage, the lithium-ion battery has been given a whole package of carefully coordinated safety measures. This innovative battery is accommodated in a high-strength steel housing, and also secured in place. Bedding the battery cells in a special gel effectively dampens any jolts and knocks. There is also a blow-off vent with a rupture disc and a separate cooling circuit. An internal electronic controller continuously monitors the safety requirements and immediately signals any malfunctions.

4. The fourth stage of the safety concept includes separation of the battery terminals, individual safety-wiring for all high-voltage components and continuous monitoring by multiple interlock switches. This means that all high-voltage components are connected by an electric loop. In the event of a malfunction the high-voltage system is automatically switched off.

5. Active discharging of the high-voltage system as soon as the ignition is switched to “Off”, or in the event of a malfunction, is part of the fifth stage.

6. During an accident, the high-voltage system is completely switched off within fractions of a second.

7. As the seventh and last stage, the system is continuously monitored for short circuits.

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 CGIoff 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 CGIand E 250 CGIare 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 CDIand 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.

In their latest assessments, the Insurance Institute for Highway Safety (IIHS) has named the new Mercedes-Benz C-Class one of their Top Safety Picks for 2009.  The news comes after the IIHS examined the C-Class in three categories – frontal offset, side impact and rear crash protection/head restraint – after which the sedan achieved top marks  of “Good” in each.

In addition to the IIHS award, the Mercedes C-Class was also awarded five stars in the Euro NCAP (the European New Car Assessment Programme), making it one of the safest cars on the market.
