2011 Mercedes-Benz E-Class Engines Now More Efficient

New petrol engines and an optimised powertrain make the 2011 Mercedes-Benz E-Class the standard for efficiency in its segment

New petrol engines and an optimised powertrain make the 2011 Mercedes-Benz E-Class the standard for efficiency in its segment. With a combined fuel consumption of only 6.8-7.0 litres and 8.9 litres * of premium petrol per 100 kilometres, the E 350 BlueEFFICIENCY and E 500 BlueEFFICIENCY excel as the most economical models in their respective performance classes. Following the introduction of the new BlueDIRECT V6 and V8 models, all petrol and diesel engines in the E-Class now feature direct injection. The reduction in fuel consumption by up to 20 percent is also due to the standard ECO start/stop function and the improved 7G-TRONIC PLUS automatic transmission, which is now also available for the four-cylinder variants**.

“E” for “Efficiency”: this is the well-proven success formula with which the E-Class is again raising the bar, and showing how the intelligent interaction between technical innovations throughout the powertrain can reduce fuel consumption even further. For example, in the E 350 BlueEFFICIENCY a combination of third-generation BlueDIRECT injection, the new 7G-TRONIC PLUS automatic transmission and the standard ECO start/stop function has led to a decrease in consumption by 20 percent compared to the preceding model, although peak output has increased by 10 kW/14 hp to 215 kW (306 hp). This high-tech V6 petrol engine is happy with 6.8-7.0 litres of premium petrol per 100 kilometres in the NEDC (New European Driving Cycle), which corresponds to CO2 emissions of 159-164 g/km. The new E 350 BlueEFFICIENCY sprints from 0 to 100 km/h in 6.3 seconds. Top speed is 250 km/h (electronically limited).

A comparable leap in efficiency is achieved by the new E 500 BlueEFFICIENCY. Despite a significantly smaller displacement (4633 cc, previously 5461 cc), the biturbo eight-cylinder with BlueDIRECT technology has gained in both output (300 kW/408 hp, previously 285 kW/388 hp) and torque (600 Nm, previously 530 Nm). At the same time its fuel consumption has fallen by around 17 percent from 10.8 to 8.9 l/100 kilometres * (NEDC combined). This too is the top figure in this perfor mance class – and is accompanied by superior performance: the new E 500 BlueEFFICIENCY sprints from 0 to 100 km/h in only 5.2 seconds. Top speed is 250 km/h (electronically limited).

Lower fuel consumption: ECO start/stop function and 7G-TRONIC PLUS

This leap in efficiency for the BlueDIRECT engines is assisted by the standard ECO start/stop function, which is now included ex factory in the four-cylinder petrol and diesel models as well. Thanks to direct-start technology, the Mercedes-Benz system for petrol engines operates both immediately and quietly.

The automatic transmission exclusively available for the E-Class in future is 7G-TRONIC PLUS **. This comprehensively improved 7-speed automatic transmission is standard equipment in the E 250 BlueEFFICIENCY, E 350 BlueEFFICIENCY and

E 500 BlueEFFICIENCY. The features of this latest evolutionary stage include a new torque converter with reduced slip, an ECO shift programme with an improved ratio spread and an auxiliary oil pump to maintain the operating pressure during automatic stops. Low-friction components and low-viscosity fluid help to reduce the operating pressure.

Major leap in efficiency: the four-cylinder diesel engines in the E-Class

Particularly in the four-cylinder variants of the E-Class, the ECO start/stop function and 7G-TRONIC PLUS make for a considerable increase in efficiency. The engine specialists have also optimised the oil pressure control and belt drive, and equipped the turbocharger with a self-regulating compressor.

Result: In the E 220 CDI BlueEFFICIENCY (125 kW/170 hp) and E 250 CDI BlueEFFICIENCY (150 kW/204 hp) the NEDC consumption CO2 emissions in combination with the 6-speed manual transmission are now only 5.0-5.3 l/100 km and 130-139 g/km. In the automatic version they have fallen by 16 percent to 4.9-5.3 l/100km and 129-138 g CO2/km*. This makes the E 250 CDI BlueEFFICIENCY the most efficient diesel model in its performance category in the luxury class. Both the

6-speed manual and 7G-TRONIC variants of the 100 kW (136 hp) E 200 CDI BlueEFFICIENCY entry-level diesel now have a combined NEDC fuel consumption of only 5.1-5.4 litres per 100 kilometres (134-141 g CO2/km).

Petrol engines at their finest: E 200 BlueEFFICIENCY and E 250 BlueEFFICIENCY

Updating the powertrain has also led to more fuel efficiency in the four-cylinder petrol engines. The 135 kW (184 hp) E 200 BlueEFFICIENCY with 7G-TRONIC PLUS now has an NEDC consumption of only 6.5-6.9 litres of premium petrol per 100 kilometres (152-160 g CO2/km). The figures with the manual 6-speed transmission are 7.1-7.4 l/100 km (169-176 g CO2/km).

Exclusively equipped with the 7G-TRONIC PLUS transmission, the E 250 BlueEFFICIENCY (150 kW/204 hp) has a 13 percent lower NEDC fuel consumption than before at 6.6-7.0 l/100 km. CO2 emissions have fallen to 154-162 g/km. This means that the E 250 BlueEFFICIENCY is likewise at the top of its class with respect to efficiency.

Luxury class with bivalent natural gas drive: E 200 NGT BlueEFFICIENCY

The E 200 NGT BlueEFFICIENCY with bivalent natural gas drive rounds off the comprehensive update to the engine range for the Mercedes-Benz E-Class. The 120 kW (163 hp) four-cylinder in the Saloon can be operated on both premium petrol and natural gas. In addition to the petrol tank, three natural gas tanks are safely accommodated in the only bivalent natural gas model in the luxury class – one behind the rear seat backrest and two under the boot floor.

They have a combined capacity of 121.5 litres of natural gas, corresponding to 19.5 kilograms. In natural gas operation, the combined NEDC consumption of the E 200 NGT BlueEFFICIENCY has fallen by 0.6 kilograms to 5.5 kilograms per 100 kilometres. This corresponds to CO2 emissions of 149 grams per kilometre. In petrol mode the combined consumption has been reduced to 8.1 l/100 km.

Mercedes-Benz Cars Named Value Champions

Mercedes-Benz vehicles proved to have the highest value retention in a 2010 study by the motoring magazine "Auto Bild"

The Mercedes-Benz E-Class and the SLS AMG super-sports car have the lowest value depreciation in their segment, and have accordingly been dubbed the “2014 residual value champions” by the German internet news magazine “Focus online”. Moreover, Mercedes-Benz vehicles proved to have the highest value retention in a 2010 study by the motoring magazine “Auto Bild”, an independent assessment confirming a major financial advantage.

According to the residual value forecast by “Focus online”, the Mercedes-Benz E 200 CDI BlueEFFICIENCY will be the upper medium-class car with the lowest value depreciation in three years time. As a used car the saloon will still achieve 53.5 percent of its current new value, easily taking the top position in this important segment. In terms of absolute euro figures, Mercedes-Benz also has the lowest value depreciation in this vehicle segment.

In three years time, admirers of the Mercedes-Benz SLS AMG will still have to pay 59 percent of the new price for a used example. The exciting gull-wing model therefore not only offers the latest technology, outstanding performance and a thrilling driving experience, but is also an excellent financial investment as a “2014 residual value champion”. A look back at history confirms this prospect, as very high prices are nowadays paid for the legendary gull-wing of the 1950s.

The rankings for the “2014 residual value champion” tables are the result of calculations by the Saarbrücken-based market research institute Bähr & Fess Forecast. This highly respected company has regularly examined the residual values of used vehicles on the basis of numerous data for many years. On behalf of “Focus online” the institute established which vehicles could be expected to have the highest residual values if purchased new in October 2010 and resold in October 2014.

At the beginning of this year the motoring magazine “Auto Bild” already gave its “Value Champion 2010” award to the Mercedes-Benz E, C, S and R-Class for the highest value retention in their segment. This confirmed the findings of studies that have regularly shown Mercedes-Benz vehicles to be among those with the highest value retention.

The New Mercedes-Benz E-Class Cabriolet: Four Seasons, Four Passengers

The highly appealing and emotionally charged Cabriolet is the latest addition to the Mercedes-Benz E-Class line-up

The highly appealing and emotionally charged Cabriolet is the latest addition to the successful Mercedes-Benz E-Class line-up. The open-top two-door model, deliveries of which start from 27 March, features a classic fabric soft top, making for a stylistically pure cabriolet feeling. Viewed from the side, the new model is an intriguing proposition – with its clear proportions and a flawless cabriolet silhouette.

In keeping with the motto “four seasons, four passengers”, all-year-round suitability was right at the top of the developers’ list of priorities. With the new E-Class Cabriolet, the cabriolet season lasts the whole year because, while many cabriolets tend to disappear from the roads of Western Europe in the autumn, the Mercedes-Benz E-Class Cabriolet (length/breadth/height: 4698/1786/1402 mm) provides driving pleasure and comfort whether the roof is open or closed.

New features include:

  • AIRCAP® automatic draught-stop: always on board and easily controllable at the push of a button, it reduces turbulence substantially for all four seat occupants
  • Modified AIRSCARF® neck-level heating system
  • Acoustic soft top fitted as standard

The soft top can be opened and closed fully automatically within 20 seconds – even when driving at speeds of up to 40 km/h. The cabriolet roof is stowed in a special compartment behind the rear panel. A retractable cover separates the soft top compartment from the boot area; this cover must be closed in order to close the soft top. If the roof is to remain closed, the cover can be slid rearwards, in which case the boot capacity is increased by 90 litres to 390 litres. A through-loading feature is included as standard for the new Cabriolet, as is EASY-ENTRY – a manually operated entry and exit aid for the rear passengers.

The powerplants for the new E-Class Cabriolet are equally innovative: the new direct-injection diesel and petrol models combine efficiency with effortlessly superior power delivery. 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 crucial factor of outstanding aerodynamics. The Cabriolet’s cd figure of 0.28 is the best in its class, marking a continuation of the E-Class success story in the field of aerodynamics.

An overview of the engines:

  • E 220 CDI BlueEFFICIENCY Cabriolet: 125 kW (170 hp)
  • E 250 CDI BlueEFFICIENCY Cabriolet: 150 kW (204 hp)
  • E 350 CDI BlueEFFICIENCY Cabriolet: 170 kW (231 hp)
  • E 200 CGI BlueEFFICIENCY Cabriolet: 135 kW (184 hp)
  • E 250 CGI BlueEFFICIENCY Cabriolet: 150 kW (204 hp)
  • E 350 CGI BlueEFFICIENCY Cabriolet: 215 kW (292 hp)
  • E 500 Cabriolet: 285 kW (388 hp)

The entry-level E 200 CGI model is fitted with an automatic transmission as standard. From June 2010, this model will also be available with a 6-speed manual transmission and the ECO start/stop function.

Less turbulence, easier to use: AIRCAP® is a world-first

In 1989, Mercedes-Benz introduced a world premiere in the shape of a draught-stop for the SL model series, followed in 2004 by the AIRSCARF® neck-level heating system to further enhance comfort in open-top models. Now comes another world-first: the AIRCAP® automatic draught-stop, which can be activated at the push of a button, greatly reduces turbulence in the interior of the new Mercedes E-Class Cabriolet,creating a sea of warm air. It is also much easier to implement and use than conventional draught-stops: there is no tricky installation, the two individual rear seats are easily accessible and the Cabriolet’s flowing side lines remain uninterrupted. AIRCAP® is therefore a classic Mercedes innovation:

functional, comfort-enhancing, elegant and safe.

AIRCAP® consists of two components: a wind deflector that can be extended by around six centimetres with a net in the windscreen frame and a draught-stop between the rear seats.

The functions of the two components:

  • Elevation of the free flow above the interior
  • Net at the front reduces the annoying vacuum in the interior
  • Draught-stop at the rear reduces the backflow

As well as enhancing occupant comfort and wellbeing, the reduction in draught when AIRCAP® is activated (it can be activated at speeds of up to 160 km/h and can remain in use right up to the car’s top speed) reduces the interior noise level – so passengers in all seats find it much easier to communicate.

The Cabriolet Comfort package includes AIRCAP® with AIRSCARF®. This patented system functions like an invisible scarf, which warms the occupants’ head and neck areas. AIRSCARF® is integrated into the backrests of the front seats and provides warm air through outlets in the head restraints.

The Mercedes engineers have modified this unique innovation specifically for the E-Class Cabriolet: in this model, an adjustment wheel pivots the outlet nozzle upwards and downwards by a total of 36 degrees over and above the head restraint height adjustment range, meaning that the driver and front passenger can enjoy the unique neck-level heating regardless of how short or tall they are.

Quiet, warm and windproof: acoustic soft top fitted as standard

Thanks to its acoustic soft top, fitted as standard, even the closed E-Class Cabriolet has one of the quietest interiors in the segment for four-seater premium cabriolets with a fabric roof. The soft top’s exceptionally high-quality insulation brings about a clearly noticeable reduction in the interior noise level compared to conventional fabric soft tops. Exterior noise caused by other vehicles and wind noise are therefore absorbed more effectively. On the road, the difference is audible from speeds of just 80 km/h, for example when driving through a tunnel or overtaking a convoy of trucks. At higher speeds, the benefits of the acoustic soft top are even more tangible. For instance, it is possible to have a perfectly normal phone conversation in hands-free mode even when travelling at a speed of over 200 km/h.

The soft top is of course waterproof and windproof. Plus it can be put through an automatic carwash without any hesitation. With a total thickness of 23.5 mm, the fabric soft top offers excellent thermal insulation, meaning that the E-Class Cabriolet is also ideal for use in winter.

Safety: robust structure, anticipatory protection and windowbags

The new Cabriolet offers the wealth of safety innovations one would expect from a Mercedes model. Highlights of the open-top two-door model include roll-over protection, the A-pillars reinforced by two additional tubes and the plug-in B-pillars. This new model is also the first Mercedes cabriolet to feature headbags. The roll-over protection 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. The plug-in B-pillars are extremely robustly connected as they engage in the side skirts, thus offering highly effective protection in the event of a crash. A shoe made from ultra-high-strength steel braces the inside of the B-pillar against the rear seat crossmember.

With seven airbags fitted as standard, belt tensioners and belt force limiters for all seats, not to mention crash-responsive head restraints for the driver and front passenger, the new E-Class Cabriolet offers the most extensive safety equipment package in this vehicle category. The airbags, which can deploy in milliseconds in the event of an accident, include front airbags and sidebags for the driver and front passenger, a kneebag on the driver’s side, and headbags. The latter, which appear in a Mercedes cabriolet for the first time, are housed in 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.

Further exemplary safety equipment available for the E-Class Cabriolet includes ATTENTION ASSIST drowsiness detection, PRE-SAFE® anticipatory occupant protection, the sophisticated Intelligent Light System, the Active Bonnet and DISTRONIC PLUS proximity control.

First Mercedes-Benz E-Class Cabriolet Handed Over at the Bremen Customer Center

Dieter Funke was personally presented with the keys to his new Mercedes-Benz E-Class Cabriolet by Peter Schabert in Bremen

Today business owner Dieter Funke was personally presented with the keys to his new Mercedes-Benz E-Class Cabriolet by Peter Schabert, Manager of the Mercedes-Benz plant in Bremen. He is the very first customer to take delivery of the two-door convertible with its classic fabric soft top at the Customer Centre, immediately after the market launch. Dieter Funke decided in favour of an E 250 CGI BlueEFFICIENCY Cabriolet in palladium silver.

Peter Schabert, Manager of the Mercedes-Benz plant in Bremen: “The highly qualified team in Bremen produces the new Cabriolet with great commitment and enthusiasm. Mercedes-Benz is adding a particularly attractive product to the successful E-Class family with this car. It is therefore a real pleasure to hand over the keys to the first owner personally today.”

Originally from the Rhineland, businessman Dieter Funke moved to Berlin around 30 years ago. He has driven cars bearing the Mercedes star for many years, including convertibles. “I really enjoy it. I covered more than 210,000 kilometres with my CLK Cabriolet, and was always happy with it – simply a wonderful car,” says Funke. As a fan of emotionally appealing two-door cars, he was particularly looking forward to the new E-Class Cabriolet – so much that he has been driving the E-Class Coupé in recent months. The E-Class Coupé and Cabriolet are produced flexibly on a single production line at the Mercedes-Benz plant in Bremen.

With the new E-Class Cabriolet, the cabriolet season lasts the whole year because, while many cabriolets tend to disappear from the roads of Western Europe in the autumn, the Mercedes-Benz E-Class Cabriolet provides driving pleasure and comfort whether the roof is open or closed.


New features include:

  • AIRCAP® automatic draught-stop: always on board and easily controllable at the push of a button, it reduces turbulence substantially for all four seat occupants
  • Modified AIRSCARF® neck-level heating system
  • The acoustic soft top fitted as standard

The AIRCAP® automatic draught-stop, which can be activated at the push of a button, greatly reduces turbulence in the interior of the new Mercedes E-Class Cabriolet, creating a sea of warm air. Thanks to the reduction in wind turbulence, activating AIRCAP® (this is possible at speeds up to 160 km/h, and it can be used even at very high speeds) not only improves occupant comfort, but also reduces noise levels – passengers on all the seats are able to converse much more easily. AIRCAP® is therefore a classic Mercedes innovation: functional, comfort-enhancing, elegant and safe.

The New Mercedes-Benz E-Class Cabriolet: the Drive System

Mercedes-Benz has taken further strides forward to reduce fuel consumption and exhaust emissions without compromising

With its newly developed direct-injection diesel and petrol engines, Mercedes-Benz has taken further strides forward in its quest to reduce both fuel consumption and exhaust emissions – without compromising on agility and driving enjoyment. The line-up of powerful and extremely efficient drive units available at sales launch ranges from the E 220 CDI BlueEFFICIENCY developing 125 kW (170 hp) to the E 500 developing 285 kW (388 hp). All of the powerplants meet the requirements of the EU 5 standard, whose limits are up to 80 percent more stringent than those specified by previous standards.

The four-cylinder diesel engine in the E 250 CDI BlueEFFICIENCY model, for example, shows just how much progress has been made: with an output of 150 kW (204 hp), a peak torque of 500 Nm and a displacement of 2.2 litres, it delivers outstanding performance yet consumes only 5.6 litres of fuel per 100 kilometres (NEDC combined figure). What’s more, CO2 emissions are just 148 grams per kilometre. All of which means that the new CDI Cabriolet is more fuel-efficient than comparable models in this output category.

Diesel engines: new four-cylinder unit featuring state-of-the-art common-rail technology

As well as being economical and ecofriendly, the four-cylinder CDI engine impresses with its exceptional agility, as reflected in the performance figures: the new E 250 CDI BlueEFFICIENCY Cabriolet takes 7.8 seconds to accelerate from 0 to 100 km/h.

Like the E 220 CDI BlueEFFICIENCY unit, this engine is part of the new series of four-cylinder powerplants, which saw Mercedes-Benz introduce the fourth generation of its tried-and-trusted common-rail direct-injection system into series production. One of its hallmarks is a 400-bar increase in the maximum rail pressure, which now stands at 2000 bar.

Newly developed piezo injectors are key components in the latest CDI engine generation. They use piezoceramic properties to change their crystal structure – and therefore their thickness – in a matter of nanoseconds when electrical voltage is applied. The new 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 even 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.

The new diesel engine in the E 250 CDI BlueEFFICIENCY model marks the debut of two-stage turbocharging in a series-production diesel engine for Mercedes-Benz passenger cars. The aim is to achieve a further improvement in start-up performance and peak output.

Six-cylinder CDI: increased output and fuel consumption of 7.0 litres per 100 kilometres

The V6 diesel engine for the E 350 CDI BlueEFFICIENCY is one of the most sophisticated compression-ignition units on the world market. It offers 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: the car accelerates from 0 to 100 km/h in 6.9 seconds. The six-cylinder unit has an output of 170 kW (231 hp).

Despite the high output and torque, fuel consumption is just 7.0 litres per 100 kilometres, equivalent to 185 grams of CO2 per kilometre. The 7G-TRONIC seven-speed automatic transmission is specified as standard for the E 350 CDI BlueEFFICIENCY.
The Mercedes engineers have gone to great lengths to optimise the technology at the heart of the V6 diesel engine, reducing the compression ratio from 17.7 to 15.5, combined with an enhanced turbocharger, ceramic glow system, modified injection nozzles and optimised air ducting.

Petrol engines: new four-cylinder unit with direct injection

CGI appears at the end of the model designation of the four- and six-cylinder petrol engines for the new E-Class Cabriolet, signifying that Mercedes-Benz uses direct petrol injection for all of these powerplants. The entry-level model is the E 200 CGI BlueEFFICIENCY developing 135 kW (184 hp), with an automatic transmission fitted as standard. This model will also be available with a 6-speed manual transmission and standard-fit ECO start/stop function from June 2010.

Compared to conventional port injection, direct fuel injection allows higher compression and, therefore, improved thermodynamic efficiency, saving motorists money at the pump: the four-cylinder direct-injection engine in the second most powerful CGI model, the E 250 CGI BlueEFFICIENCY, consumes just 7.9-8.2 litres per 100 kilometres, with an output of 150 kW (204 hp) and a peak torque of 310 Nm. Mercedes-Benz equips the Cabriolet featuring this engine with a five-speed automatic transmission as standard.

Six-cylinder engine: CGI technology with spray-guided combustion

The E 350 CGI BlueEFFICIENCY Cabriolet is powered by the world’s first petrol engine to feature spray-guided combustion. 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, fuel consumption is reduced to 8.8 litres per 100 kilometres (NEDC combined figure). The seven-speed automatic transmission comes as standard. What’s more, the highly economical and environmentally compatible CGI powerplant provides a unique driving experience: it takes the V6 Cabriolet 6.8 seconds to accelerate from 0 to 100 km/h.

Precision-modified eight-cylinder engine

The eight-cylinder unit in the E 500 Cabriolet is the flagship powerplant, providing 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 top-of-the-range model, which is equipped with the 7G-TRONIC seven-speed automatic transmission as standard: 0 to 100 km/h in 5.3 seconds.

The New Mercedes-Benz E-Class Cabriolet: Design

The E-Class Cabriolet, which combines an elegant appearance with a high awareness of tradition, had to have a soft top

From the very first drawings onwards, the Mercedes designers were sure of one thing: only a classic fabric soft top can convey a stylistically pure cabriolet feeling. Consequently, the new E-Class Cabriolet, which combines an elegant appearance with a high awareness of tradition, had to have a soft top. Viewed from the side, the two-door model therefore offers an enticing mix of clear proportions and a flawless cabriolet silhouette, including a long bonnet, wide doors, a high beltline with elongated side windows, a lowered soft top contour, and a short rear overhang. This look is complemented by the powerfully muscular section in the side wall at the rear axle and a slender C-pillar.

As well as sharing family traits with the other E-Class models, the new Cabriolet has its own, distinct identity characterised by a greater sense of passion. The arrow shape of the entire front section from front bumper to radiator grille to bonnet, the more extreme interpretation of the twin headlamp face and its more sinewy build give it a racier and more dynamic presence than the Saloon. At the same time, the close family ties with the E-Class Coupé are clearly apparent.

Powerful styling accentuates the sleek, flowing lines

A special characteristic of the contemporary Mercedes design idiom is the creative interplay of edges and surfaces. Taut, sharply defined lines, which grow out of surfaces organically and disappear into them again equally gently, structure the sides of the Cabriolet. The high shoulderline, a prominent, downward-pointing feature line (another contemporary Mercedes styling element) and a second structuring line delimit the sensitively sculpted surfaces. Alternately concave and convex, these create a sleek yet sharply defined flow of lines which creates a fascinating interplay of reflected incident light.

Arrow-shaped front and dominant radiator grille

From the front bumper to the radiator grille to the bonnet, the pronounced arrow shape of the front section emphasises the sporty character of the Cabriolet. A central crease in the bonnet picks up this shape and trails back towards the windscreen. A wide, upright radiator grille with two louvres, striking chrome strips, a powerful chrome surround and the central star testifies to status and self-assurance in time-honoured Mercedes style. The grille makes an effortlessly superior, expressive statement of the brand’s identity.

The traditional twin headlamp face is based on that of the new E-Class Saloon, but has its own distinct identity. Longer, more sharply inclined and flatter, the headlamps have a more dynamic look which is unmistakable. With their elaborate, high-tech interior and quadrant-shaped indicators, they add a sparkling finishing touch to the front of the car.

A distinctive front apron with large air intakes gives the vehicle a strong, powerful presence. Two vertical struts in the front apron provide visual support for the radiator grille and give it a substantial formal base. Depending on the model version, the bumper houses either the fog lamps or the daytime driving lights and fog lamps side by side. In the versions with bi-xenon headlamps, L-shaped daytime driving lights based on LED technology give the car an expressive look.

Powerful rear with innovative lights

“Powerful and not afraid to show it” could be the motto for the rear section of the new E-Class Cabriolet: the rear wings spanning the rear axle are sculpted to create a powerful, muscular form which visually enhances the car’s width. The distinctive feature line – a characteristic Mercedes styling element – is continued masterfully around the back of the vehicle and into the tail lights, thereby forming a link between front and rear.

The LED tail lights are split and extend from the boot lid far into the side wall. In so doing, they emphasise the width and dynamism of the vehicle. Their innovative lighting technology is particularly noteworthy. An LED background lighting system provides indirect illumination of the three-dimensional back cavity in both light units and in this way sets the basic background lighting tone. Twin light arrays with twin LED light guides stand out against the background lighting. These light arrays accommodate the tail lights and the brake lights, while the reversing lights and the LED‑fog lamp are integrated in the boot lid light clusters.

The narrowness of the gap between the light unit on the boot lid and that on the side wall, as well as the extremely precise bevelling of the adjacent light lenses allows light transmission between the two sections. As a result, the night design of the new Cabriolet maintains the perceived width and harmonious appearance of the rear section.

Interior with sporty lines and high perceived value

In the interior, the designers have continued the taut, sporty design idiom of the exterior. The compelling interplay of surfaces and clearly defined lines creates an interior whose elegance and high perceived value are evocative of modern architecture. The cockpit is structured horizontally with a dark upper section in order to avoid unwanted reflections. Interior appointments in two colours – in keeping with the logic of the two-level structure – create intriguing contrasts.

With its sporty look and feel, the cockpit design is clearly in keeping with the agile character of the new Cabriolet. The instrument cluster with five tubes for the dials and a central display has a slender look, while the dials themselves are clearly laid out and have high-quality chrome surrounds as well as a silver backing for the scales. The background colour of the dashboard is silver or black, depending on the choice of trim parts. The three-spoke steering wheel with multifunction buttons is available in a number of different versions and colours in order to match the interior appointments.

Next to the instrument cluster – and therefore in the primary field of vision of the driver and front passenger – is the display area for the control and display system for the radio, navigation system and other functions. The system is operated by means of a rotary and push-action Controller, which falls conveniently to hand in front of the asymmetrically split armrest between the front seats. This armrest also serves as a handrest when operating the Controller. Beneath this are the control buttons for the soft top and AIRCAP®. The horizontally divided dashboard merges into a dynamic, arrow-shaped centre console in which the air-conditioning controls, for example, are integrated.

Sporty individual seats for the rear passengers, too

The new E-Class Cabriolet is an out-and-out four-seater and also has sportily designed individual seats in the rear. The front integral seats with pronounced, faceted side bolsters and transverse piping on the seat cushion have a light, contemporary look and immediately create a distinctly sporty impression, while offering excellent seating comfort. Another notable characteristic of the seats is the high-quality, hand-stitched workmanship featuring discreet flat-felled seams. Further highlights include the audio system’s loudspeakers housed in the soft top compartment cover, which add an extra visual touch, especially when the roof is open.

Fine materials

The whole interior is dominated by pleasing surface finishes. Trim elements made from valuable, authentic materials emphasise the high-quality of the new Cabriolet. The sporty two-door model is equipped as standard with brushed aluminium trim parts with a sporty spin finish. Customers can also choose from fine woods: burr walnut, high-gloss black ash or the graphic linearity of pine. In all cases, the trim parts have a thin chrome strip along their upper edge.

Mercedes-Benz at the Geneva International Automobile Salon 2010

Premium automobiles that combine environmental responsibility with the pure fascination of Mercedes-Benz

“We’re driving for victory not only in Formula 1, but also in ‘Formula Green’ – with premium automobiles that combine environmental responsibility with the pure fascination of Mercedes-Benz.” These were the words of Dr. Dieter Zetsche, Chairman of the Board of Management of Daimler AG and Head of Mercedes-Benz Cars, speaking today at the press conference marking the opening of the 2010 Geneva Salon. The brand with the three-pointed star is demonstrating here that the lowest consumption and CO2 figures can also be achieved with large, comfortable vehicles equipped with refined engines.

Star of the Premium Class in Geneva: F 800 Style with “green” technology and avant-garde design

One particularly impressive example of this is the F 800 Style which, here in Geneva, Mercedes-Benz is presenting under the title “efficiency meets elegance”. The new research vehicle delivers a comprehensive glimpse into the future of the premium automobile. The five-seat luxury class saloon, which offers a generously proportioned interior with intelligent seating, operating and display concepts, combines highly efficient drive technologies with innovative comfort and safety functions, as well as an emotional design language that interprets modern Mercedes design in line with the brand’s hallmark cultivated sporting character. A global first for large saloons is the all-new variable drive architecture. It is suitable for both fuel-cell electric drive, for a range of around 600 kilometres, and for use as a plug-in hybrid, with an overall range of around 700 kilometres and an electric-only range of 30 kilometres. Both variants of the F 800 Style enable premium mobility with zero local emissions combined with complete everyday usability.

“With the F 800 Style, we are underscoring our drive to bring together responsibility for the environment with practical customer benefits and automotive fascination”, said Dr. Thomas Weber, Member of the Board of Management of Daimler AG responsible for Group Research and Development Mercedes-Benz Cars. “Our new research vehicle combines this leadership role in innovative drive concepts with classic Mercedes strengths in the fields of design, safety, comfort and superb performance.”

With an exterior vehicle length of 4.75 metres (wheelbase 2,924 mm, width 1,938 mm), all the components of the efficient and environmentally-friendly drive are packaged for optimum space usage in the engine bay of the F 800 Style and in cavities within the vehicle chassis. In terms of compact construction, both the plug-in hybrid and fuel cell systems require comparatively little packaging space. Thus, the interior of the F 800 Style is completely unencumbered.

F 800 Style with plug-in-hybrid – refined performance with 68 grams of CO2

In developing the F 800 Style with plug-in hybrid, Mercedes engineers paid particular attention to the further development of all-electric driving in urban traffic. Its drive unit consists of a V6 petrol engine with next-generation direct injection developing around 220 kW (300 hp) and a hybrid module with around 80 kW (109 hp) fully integrated into the casing of the 7G-TRONIC seven-speed automatic transmission, as in the Mercedes-Benz S 400 HYBRID launched in mid-2009. Its substantial power reserves facilitate a top speed in electric mode of 120 km/h. This means that the F 800 Style can also handle out-of-town traffic conditions. The overall output of the hybrid drive stands at around 300 kW (409 hp).

The efficient drive and a CO2 bonus for battery-electric operation enable the F 800 Style to attain a certified consumption figure of 2.9 litres of petrol per 100 kilometres. This results in CO2 emissions of 68 grams per kilometre. With its efficient drive, the F 800 Style marks another step towards market readiness for the plug-in hybrid, which Mercedes-Benz will put into series production with the next-generation S-Class.

Considerable efficiency improvements in the new C and E-Class models

The brand with the three-pointed star is demonstrating its consistent approach to efficiency at the Geneva Salon with two new series production models – the new E 250 CDI BlueEFFICIENCY consumes only 4.9 instead of 5.8 l/100 km, while its CO2 emissions are down from 154 to 129 g/km (preliminary combined figures). The C 220 CDI BlueEFFICIENCY gets by on 4.5 l/100 km or 119 g CO2/km. Both models now have a special automatic start/stop system – combined in the E-Class for the first time with the further developed 7-speed automatic transmission.

Zetsche: “We have significantly reduced consumption and emissions with our BlueEFFICIENCY offensive. Our new models boast an excellent ratio of performance to CO2 emissions, thereby achieving an outstanding degree of efficiency.”

E 300 BlueTEC HYBRID – first diesel hybrid from Mercedes-Benz delivers amazing efficiency

Another particularly impressive example of this is the E 300 BlueTEC HYBRID. The first diesel hybrid from Mercedes-Benz has already successfully entered everyday testing and is scheduled for market launch next year. Its 15 kW electric motor facilitates electric-only driving and supports the 150 kW (204 hp) four-cylinder diesel engine under acceleration (boost effect). With a combined output of 165 kW (224 hp), the E 300 BlueTEC HYBRID consumes 4.1 l/100 km. That equates to CO2 emissions of 109 g/km. This sets the comfortable, safe and smooth-running luxury saloon apart not only from its direct competitors, but also from smaller vehicles with considerably less power. When it comes to efficiency, this differential is even greater – with CO2 emissions of 0.48 grams per hp, the E 300 BlueTEC HYBRID achieves an outstanding result.

“The E 300 BlueTEC HYBRID is yet another impressive demonstration of our ability to build the most efficient vehicles in the world,” said Dr. Thomas Weber. “Efficiency is a core element of our development strategy that we are implementing consistently in line with the formula – refined performance with simultaneously low consumption. And this enables us to fulfil the high expectations of our customers – exceptional environmental sustainability without sacrificing safety, comfort and dynamics.”

The new E-Class Cabriolet – “four seasons, four passengers”

The new E-Class Cabriolet, which celebrates its European premiere in Geneva, offers refined open-air driving fun from 5.4 l/100 km. “With the open-top four-seater, our successful E-Class family is complete,” said Dr. Joachim Schmidt, Head of Sales and Marketing Mercedes-Benz Cars. “The E-Class is very well received on the market; the saloon is currently the world’s best-selling car in its segment. In Western Europe, it has achieved a market share of 31 percent, and in Germany, as much as 56 percent.”

Thanks to its classic soft top, the open four-seater delivers that pure convertible feeling. True to the motto “four seasons, four passengers”, it combines comfort, elegance and year-round usability. This comes courtesy of features such as the unique automatic AIRCAP® wind deflector that deploys at the touch of a button and significantly reduces turbulence in the vehicle interior. It dispenses with the assembly usually associated with conventional wind deflectors and doesn’t interfere with the side profile of the cabriolet. Additional equipment also includes a redeveloped version of the AIRSCARF® neck-level heating system integrated into the front seat backrests, which blows warm air from adjustable air vents in the head restraints and warms occupants around the neck area like an invisible scarf.

For comfortable travel with the roof closed, there is the production standard sound-dampening roof. With this, the E-Class Cabriolet boasts one of the quietest interiors in the segment of four-seat premium soft-top cabriolets. The roof can be opened and closed at the touch of a button in just 20 seconds – even while driving at speeds of up to 40 km/h. Like all E-Class models, the Cabriolet, too, offers an outstanding level of safety. Standard equipment includes the “ATTENTION ASSIST” drowsiness detection system, “PRE-SAFE®” anticipatory occupant protection, the “Intelligent Light System” and the “DISTRONIC PLUS” adaptive cruise control.

Mercedes-Benz SLS AMG – Official F1™ Safety Car

A further highlight of the 2010 Geneva Automobile Salon comes from the motorsport sector. When the new Formula 1 season starts in Manama, Bahrain (12 – 14 March 2010), it will do so with the most spectacular and highest-performing Official F1™ Safety Car of all time. The Mercedes-Benz SLS AMG, celebrating its launch on 27th March 2010, is responsible for ensuring maximum safety in Formula 1. The Gullwing takes over from the SL 63 AMG, which served as the Official F1™ Safety Car in 2008 and 2009.

Mercedes-Benz at the 2010 Geneva International Motor Show: Mercedes-Benz E-Class Cabriolet

The highly appealing and emotionally charged Cabriolet is the latest addition to the successful Mercedes-Benz E-Class line-up.

The highly appealing and emotionally charged Cabriolet is the latest addition to the successful Mercedes-Benz E-Class line-up. The open-top two-door model features a classic fabric soft top, making for a stylistically pure cabriolet feeling. Viewed from the side, the new model is an intriguing proposition – with clear proportions and a flawless cabriolet silhouette.

In keeping with the motto “four seasons, four passengers”, all-year-round suitability was right at the top of the developers’ list of priorities. With the new E‑Class Cabriolet, the open-top season lasts the whole year because, while many cabriolets tend to disappear from the roads of Western Europe in the autumn, the Mercedes-Benz E-Class Cabriolet (length/width/height: 4698/1786/1402 mm) continues to provide driving pleasure and comfort at this time of year.

New features include:

  • AIRCAP® automatic draught-stop: always on board and easily controllable at the push of a button, it reduces turbulence substantially for all four seat occupants
  • Modified AIRSCARF® neck-level heating system
  • Acoustic soft top fitted as standard

The soft top can be opened and closed fully automatically within 20 seconds – even when driving at speeds of up to 40 km/h. The cabriolet roof is stowed in a special compartment behind the rear panel. A retractable cover separates the soft-top compartment from the boot area; it must be closed in order to close the soft top. If the roof is to remain closed, the cover can be slid rearwards, in which case the boot capacity is increased by 90 litres to 390 litres. A through-loading feature is included as standard for the new Cabriolet, as is EASY-ENTRY – a manually operated entry and exit aid for the rear passengers.

The powerplants for the new E-Class Cabriolet are equally innovative: the new direct-injection diesel and petrol models combine efficiency with effortlessly superior power delivery. The exemplary, low fuel consumption is not only down to the new engines, but also thanks to 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 crucial factor of outstanding aerodynamics. The Cabriolet’s cd figure of 0.28 is the best in its class, marking a continuation of the E-Class success story in the field of aerodynamics.

An overview of the engines :

  • E 220 CDI BlueEFFICIENCY Cabriolet: 125 kW (170 hp)

Less turbulence, easier to use: AIRCAP® is a world-first

In 1989, Mercedes-Benz introduced a world premiere in the shape of a draught-stop for the SL model series, followed in 2004 by the AIRSCARF® neck-level heating system to further enhance comfort in open-top models. Now comes another world-first: the AIRCAP® automatic draught-stop, which can be activated at the push of a button, greatly reduces turbulence in the interior of the new Mercedes E-Class Cabriolet, creating a “sea of warm air”. It is also much easier to implement and use than conventional draught-stops: there is no tricky installation, the two individual rear seats are easily accessible and the Cabriolet’s flowing side lines remain uninterrupted. AIRCAP® is therefore a classic Mercedes innovation: functional, comfort-enhancing, elegant and safe .

AIRCAP® consists of two components: a wind deflector that can be extended by around six centimetres with a net in the windscreen frame and a draught-stop between the rear seats.

The functions of the two components:

  • Elevation of the free flow above the interior
  • Net at the front reduces the annoying vacuum in the interior
  • Draught-stop at the rear reduces the backflow

As well as enhancing occupant comfort and wellbeing, the reduction in draught when AIRCAP® is activated (it can be activated at speeds of up to 160 km/h and can remain in use right up to the car’s top speed) reduces the interior noise level – so passengers in all seats find it much easier to communicate with each other.

The Cabriolet Comfort package includes AIRCAP® with AIRSCARF®. This patented system functions like an invisible scarf, which warms the occupants’ head and neck areas. AIRSCARF® is integrated into the backrests of the front seats and provides warm air through outlets in the head restraints.

The Mercedes engineers have modified this unique innovation specifically for

the E-Class Cabriolet: in this model, an adjustment wheel pivots the outlet nozzle upwards and downwards by a total of 36 degrees over and above the head restraint height-adjustment range, meaning that the driver and front passenger can enjoy the unique neck-level heating regardless of how short or tall they are.

Quiet, warm and windproof: acoustic soft top fitted as standard

Thanks to its acoustic soft top fitted as standard, when closed the E-Class Cabriolet has one of the quietest interiors in the segment for four-seater premium cabriolets with a fabric roof. The soft top’s exceptionally high-quality insulation brings about a clearly noticeable reduction in the interior noise level compared to conventional fabric soft tops. Exterior noise caused by other vehicles and wind noise are therefore absorbed more effectively. On the road, the difference is audible from speeds of just 80 km/h, for example when driving through a tunnel or overtaking a convoy of trucks. At higher speeds, the benefits of the acoustic soft top are even more tangible. For instance, it is possible to have a perfectly normal phone conversation in hands-free mode even when travelling at a speed of over 200 km/h.

The soft top is of course waterproof and windproof. Plus it can be put through an automatic carwash without any hesitation. With a total thickness of 23.5 mm, the fabric soft top offers excellent thermal insulation, meaning that the E‑Class Cabriolet is also ideal for use in winter.

Safety: robust structure, anticipatory protection and windowbags

The new Cabriolet offers the wealth of safety innovations one would expect from a Mercedes model. Highlights of the open-top two-door model include roll-over protection, the A-pillars reinforced by two additional tubes and the plug-in B‑pillars. This new model is also the first Mercedes cabriolet to feature headbags.

The roll-over protection 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. A tilting cone sensor detects imminent danger to the occupants based on extreme skidding movements or acceleration caused by impact. If this sensor then sends a corresponding signal, 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, the steel bars provide highly effective roll-over protection. The plug-in B-pillars are extremely robustly connected as they engage in the side skirts, thus offering highly effective protection in the event of a crash. A shoe made from ultra-high-strength steel braces the inside of the B-pillar against the rear seat crossmember.

With seven airbags fitted as standard, belt tensioners and belt force limiters for all seats, not to mention crash-responsive head restraints for the driver and front passenger, the new E-Class Cabriolet offers the most extensive safety equipment package in this vehicle category. The airbags, which can deploy in milliseconds in the event of an accident, include front airbags and sidebags for the driver and front passenger, a kneebag on the driver’s side, and headbags. The latter, which appear in a Mercedes cabriolet for the first time, are housed in 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 large and small occupants 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.

Further exemplary safety equipment available for the E-Class Cabriolet includes ATTENTION ASSIST drowsiness detection, PRE-SAFE® anticipatory occupant protection, the sophisticated Intelligent Light System, the Active Bonnet and DISTRONIC PLUS proximity control.

Mercedes-Benz E-Class Awarded Best Power-to-Economy Ratio by Diners Club Magazine

Mercedes E 250 CDI BlueEFFICIENCY voted "Car of the year with the best power-to-economy ratio" by Diner's Club

The readers of the Diners Club Magazine have elected the Mercedes E 250 CDI BlueEFFICIENCY as the “Car of the year with the best power-to-economy ratio”. Thanks to its state-of-the-art diesel technology, the 150-kW/204-hp engine burns just 5.3 litres of diesel per 100 kilometres on the combined NEDC cycle. This equates to 139 grams of CO2 per kilometre.

Andreas Friedrich, chief engineer for the new Mercedes E-Class, was on hand to accept the Diners Club Magazine award at a gala ceremony held on 12 November in Munich’s GOP Varieté Theatre. “The E 250 CDI BlueEFFICIENCY is the proof that ecology and driving pleasure do not have to be mutually exclusive. The engine summons up more power from a smaller displacement while achieving the sort of fuel consumption figures previously only associated with the compact class,” remarked Friedrich. “The model’s exemplary efficiency is further enhanced by its exceptional aerodynamics, which make the E-Class the world’s most streamlined saloon.”

It is not just the readers of the Diners Club Magazine who are impressed by the new E-Class: it is highly popular with customers around the world and the market leader in its segment. Following the launch of the Saloon and Coupé, the third body variant – the Estate – is just arriving in dealer showrooms. All three are available in the E 250 CDI BlueEFFICIENCY version.

Mercedes-Benz Adds Two New Four-Cylinder Models to the 2010 E-Class Lineup

Mercedes is adding two four-cylinder's to the 2010 E-Class lineup: the E200 CDI BlueEFFICIENCY and the E200 CGI BlueEFFICIENCY

Mercedes has announced today that they’re adding two new four-cylinder models to the 2010 E-Class lineup:  the E200 CDI BlueEFFICIENCY and the E200 CGI BlueEFFICIENCY.  Key highlights of the E200 CDI include a displacement of 2143 cc, output of 100 kW/136 hp and fuel consumption of 5.2-5.5 liters per 100 kilometers (about 44 mpg). As for performance, the E200 CDI can accelerate from 0-62mph in 10.2 seconds and reach a top speed of 130 mph.

The new petrol four-cylinder E-Class – the E200 CGI – boasts a displacement of 1796 cc, output of 135 kW/184 hp and fuel consumption of 7.2 liters per 100 kilometers (about 32.5 mpg). Acceleration from 0-62 mph comes in at 8.5 seconds, while top speed is a suitable 144 mph.

Pricing for the four-cylinder E-Class variants starts at € 38,734.50 for the 2010 E200 CDI BlueEFFICIENCY and € 39,508 for the 2010 E200 CGI BlueEFFICIENCY, with the market launch of both expected to be in September 2009.

Mercedes-Benz at the New York International Auto Show: the Mercedes E250 BlueTEC

Thanks to the effective exhaust treatment system Mercedes-Benz developed, BlueTEC vehicles fulfil the global emissions standards

BlueTEC is the keyword for the future of diesel engine technology. Thanks to the highly effective exhaust treatment system developed by Mercedes-Benz, BlueTEC vehicles fulfil the strictest global emissions standards to make them the cleanest diesels in the world. With the E 250 BlueTEC concept, which was created specifically for the North American market, Mercedes-Benz is now demonstrating how BlueTEC technology in the E-Class can be combined with a four-cylinder engine with optimised fuel consumption. When fitted to the 7G-TRONIC seven-speed automatic transmission, the E 250 BlueTEC boasts fuel economy of 28 mpg U.S. in city traffic and 39 mpg U.S.on the motorway (U.S. FE standards). The E 250 BlueTEC concept fulfils the strictest emissions standards, including Bin 5 in the U.S., and would even meet the considerably toughened limits laid down in EU6 legislation not due for implementation until 1 September 2014.

The EU6 standard specifies maximum nitrogen oxide emissions that are less than half of those permitted by the current EU5 standard. The following is an overview of the current and future limits for diesel vehicles in the EU*:

For the E 250 BlueTEC, the modern 2.2 litre four-cylinder CDI engine underwent a detailed redevelopment program in order to reduce further the internal raw emissions generated by the engine and to fulfil the legislative requirements for on-board diagnostics (OBD), as well as other factors. The power unit hardware incorporates features from the series production engines, such as four-valve technology, fourth-generation common-rail piezo direct injection, 2-stage turbocharger and exhaust gas recirculation. A highly sensitive electronic engine control system reacts precisely across the full range of operating conditions to optimise the combustion process. The exhaust gas treatment system incorporates an oxidation catalytic converter mounted close to the engine, as well as a diesel particulate filter, which is located at the rear bulkhead in order to shorten its regeneration time.

At the heart of the BlueTEC system are two SCR catalytic converters (Selective Catalytic Reduction) with an “AdBlue®” injector positioned upstream. “AdBlue®” is a synthetic, aqueous urea solution that enables the nitrogen oxide (NOx) to be converted into harmless nitrogen gas in the SCR catalytic converters.

The monitoring and diagnosis of the sophisticated exhaust gas treatment process is handled by several sensors, including a differential pressure sensor, a Lambda probe plus NOx and temperature sensors.

For on-board storage of the “AdBlue®” solution, the E 250 BlueTEC has a 25 litre tank equipped with a membrane pump, valve, pressure and temperature sensors and an electrical heating unit, which prevents the 33-percent urea solution from freezing at extremely low temperatures. The tank volume is sufficient for the duration of a full service interval and is refilled as part of the regular maintenance schedule. The “AdBlue®” tank is integrated into the spare wheel well in the boot.

E 250 BlueTEC combines environmental awareness, driving fun and comfort

The combination of the powerful four-cylinder engine with SCR technology makes a convincing argument not only in terms of fuel economy and emissions, but also with impressive performance and the associated fun factor. Thanks to a pair of Lanchester balancing shafts, the concept vehicle’s powertrain boasts the exceptionally smooth characteristics expected of a Mercedes-Benz.

The 2010 Mercedes-Benz E-Class: BlueEFFICIENCY Technology

The Mercedes commitment to reducing fuel consumption and carbon-dioxide emissions targets actual driver usage profiles

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.

The 2010 Mercedes-Benz E-Class: Drive System

The Mercedes strategy is to use turbocharged engines with lower displacement in place of high-displacement, non-turbocharged

“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 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.

Mercedes-Benz at the Geneva Motor Show: The New Mercedes E-Class Coupé

The Geneva Motor Show will see the comeback of an intriguing idea when Mercedes-Benz presents the new E-Class Coupé

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.

The Mercedes-Benz E-Class Coupe Makes its World Debut

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 also

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.

2010 Mercedes-Benz E-Class Brochure Makes its Way Onto the Web

The new 2010 Mercedes-Benz E-Class prior to its debut at the Geneva Motor Show, the model's brochure made its way onto the Web

Just when you thought you couldn’t see any more of the new 2010 Mercedes-Benz E-Class prior to its upcoming debut at the Geneva Motor Show, a healthy portion of the model’s brochure has made its way onto the Web, revealing completely both the model’s exterior and interior styling as well as key technical specifications. This, of course, comes after a prior series of leaked official photos, meaning Mercedes’ viral marketing team has either been working overtime or the new E-Class is one of the worst kept secrets in automotive history.

Either way, the European market now knows exactly what to expect from the model, starting with the fact that there will be by our count a total of ten engine variants (not including an AMG model). There’s three CGI BlueEFFICIENCY variants – the E 200 CGI BlueEFFICIENCY, the E 250 CGI BlueEFFICIENCY and the E 350 CGI BlueEFFICIENCY – and there’s four CDI BlueEFFICIENCY variants – the E 200 CDI BlueEFFICIENCY, the E 220 CDI BlueEFFICIENCY, the E 250 CDI BlueEFFICIENCY and the E 350 CDI BlueEFFICIENCY. Rounding out the lot, an E350 BlueTEC, a traditional E 350 4MATIC, and the stalwart E 500 will all be available as well.

As for the rest of the model details, I’d tell you more, but to honest, it’ll be far easier to simply view the tech specs in the brochure for yourself. To see a small portion of the 2010 Mercedes E-Class brochure, keep scrolling for an excerpt (click any photo to enlarge), then head over to WorldCarFans where you can find the vastly extended leaked brochure pages.
