S400 BlueHYBRID

Mercedes-Benz is launching its first passenger car model equipped with a hybrid drive system in summer 2009 - the Mercedes-Benz S400 BlueHYBRID. The combination of a modified V6 petrol engine and a compact hybrid module makes the Mercedes-Benz S400 BlueHYBRID the world's most economical luxury saloon with a spark-ignition engine. The NEDC combined fuel consumption is a mere 7.9 litres per 100 kilometres. This makes for the world's lowest CO2 emissions in this vehicle and performance class - just 190 grams per kilometre. These exemplary figures go hand in hand with assured performance. The 3.5-litre petrol engine develops an output of 205 kW/279 hp, the electric motor generates 15 kW/20 hp and a starting torque of 160 Nm. The result is a combined output of 220 kW/299 hp and a combined maximum torque of 385 newton metres. Moreover, the new Mercedes-Benz S400 BlueHYBRID is the first series-production model to be equipped with a particularly efficient lithium-ion battery specially developed for automotive use. This is another major contribution by Mercedes-Benz to the electrification of the car.
The new Mercedes-Benz S400 BlueHYBRID is based on the S350, and features an extensively modified drive train. This encompasses a further development of the 3.5-litre V6 petrol engine, an additional magneto-electric motor, the 7G-TRONIC seven-speed automatic transmission specially configured for the hybrid module, the necessary operating and control electronics, the transformer and a high-voltage lithium-ion battery.

The compact hybrid module is a disc-shaped electric motor that also acts as a starter and generator. The system offers a double benefit, as it both helps to save fuel and increases driving enjoyment. This is partly due to the booster effect of the electric motor, as it powerfully backs up the petrol engine with a maximum additional torque of 160 newton metres during the high-consumption acceleration phase. The driver benefits from the combined action of these two units in the form of even more impressive torque characteristics and smooth, effortlessly superior acceleration.The hybrid module also has a comfortable start/stop function, which switches the engine off when the vehicle is at a standstill - for example at traffic lights. When it's time to move off again, the electric motor almost imperceptibly restarts the main power unit. This likewise makes a contribution to fuel economy and environmental protection: because the engine restarts first time, and practically instantly, emissions are also minimised during the starting phase.When the vehicle is braked the electric motor acts as a generator, and is able to recover braking energy by a process known as recuperation. Working in finely tuned partnership, the electric motor supplements the braking effect of the petrol engine and the wheel brakes to deliver a smoothly progressive braking action. The recuperated energy is stored in a compact yet highly efficient lithium-ion battery in the engine compartment, and made available when required. This complex system is managed by a high-performance control unit, which is likewise located in the engine compartment.A milestone on the road to electrification

The centrepiece of the modular, very compact and highly efficient hybrid drive system is the new high-voltage lithium-ion battery, which was specially developed for automotive use and is the first such unit worldwide to be introduced in a series-production vehicle. In this way Mercedes-Benz is making a trailblazing contribution to the electrification of the car, with the Mercedes-Benz S-Class once again playing the role of the technological trendsetter.


Major advantages over conventional nickel/metal hydride batteries include a higher energy density and better electrical efficiency, together with more compact dimensions and a lower weight. Thanks to space-saving installation in the engine compartment, where it replaces the conventional starter battery, the generous interior space and boot capacity of the S400 remain unchanged. The lithium-ion battery not only stores energy for the electric motor, but is also connected to the 12-Volt onboard network via the transformer to supply power to other standard consumers such as the headlamps and comfort features. The completely newly designed battery system consists of the cell block with its lithium-ion cells and the cell monitoring system, the battery management function, the high-strength housing, the cooling gel, the cooling plate, the coolant feed and the high-voltage connector.
Optimised thermal efficiency lowers the engine's fuel consumption
The 3.5-litre V6 petrol engine with variable valve control has been throughly re-engineered and improved. In the process the development engineers made use of the advantages offered by the Atkinson principle,where the expansion phase is longer than the compression phase. The intake valve is kept open slightly longer between the intake and compression phases, which improves the engine's thermal efficiency while reducing the specific fuel consumption and untreated emissions. A new cylinder head, different pistons and a modified camshaft with different camshaft control increase the output by 5 kW/7 hp to 205 kW/279 hp - while reducing fuel consumption at the same time.

Especially on rural journeys and on motorways, the Mercedes-Benz S400 BlueHYBRID achieves a further efficiency improvement by moving the so-called operating point of the petrol engine to produce a lower specific fuel consumption. The extremely high start-off torque made possible by the boost effect of the electric motor gives the driver a particularly exhilarating feeling of powerful acceleration, while fuel consumption and emissions are reduced.
The electric motor improves efficiency
The compact, disc-shaped electric motor, which is space-savingly installed in the torque converter housing between the engine and the 7G-TRONIC seven-speed automatic transmission, improves efficiency even further. This is a 3-phase AC external rotor magneto motor, which develops a peak output of 15 kW/20 hp and a starting torque of 160 newton metres with an operating voltage of 120 Volts.
This compact motor also acts as a starter and generator, adopting the functions of both these conventional ancillary units.


Sophisticated interaction with the internal combustion engine makes numerous additional functions possible that positively influence the emissions and agility of the Mercedes-Benz S400 BlueHYBRID in equal measure. Moreover, this disc-shaped motor effectively dampens torsional vibrations in the drive train, thereby further reducing noise and vibrations in the interior. The result is even more ride comfort for both driver and passengers.
"Boost" effect for even more driving pleasure
The overall system offers extensive benefits: firstly by helping to save fuel, and secondly by increasing driving pleasure with the help of the "boost" effect, where the electric motor gives powerful assistance to the petrol engine with its maximum torque of 160 newton metres right from the beginning of the fuel-intensive acceleration phase. This means that the hybrid drive system of the Mercedes-Benz S400 BlueHYBRID moves off powerfully even from very low engine speeds, as the torque curve impressively confirms. The additional torque of the hybrid module also has a consistently positive effect during subsequent acceleration phases. In all driving situations, the driver therefore benefits from the interaction between the two units in the form of powerful responsiveness and muscular torque - but without an increased fuel consumption.
The Mercedes-Benz S400 BlueHYBRID accelerates from zero to 100 km/h in 7.2 seconds, and reaches an electronically governed top speed of 250 km/h. The Mercedes-Benz S400 BlueHYBRID betters the already very favourable NEDC fuel consumption of the conventionally powered S350 by up to 2.2 litres per 100 kilometres. CO2 emissions are reduced by 21 percent.
The start/stop function already saves fuel when rolling to a stop
In addition the hybrid module features an extremely comfortable and efficient start/stop function, which already switches the engine off when the vehicle is rolling to a stop at less than 15 km/h, for example before stopping at traffic lights. When it's time to move off again, the electric motor immediately and imperceptibly restarts the main engine as soon as the driver releases the brake pedal or operates the accelerator. This likewise contributes to fuel economy and environmental conservation: as the engine restarts practically instantly, emissions are also minimised during the starting phase. The vibrations and jolts that are unavoidable when starting with a conventional starter are also reduced to a minimum.
Steering and climatic comfort remain unchanged, as both the steering servo pump and the refrigerant compressor are electrically powered. Both systems therefore continue to operate even when the vehicle is at a standstill with the engine automatically switched off. The intelligent control logic is able to detect whether the driver is executing a turning or parking manoeuvre. In this case the automatic start/stop function is temporarily deactivated, so that these manoeuvres can be carried out in comfort.
Every braking action generates electric power for the battery
When the vehicle is braked, the electric motor acts as a generator and uses a process known as recuperation to convert the kinetic energy into electrical energy. This energy is stored in the compact yet highly efficient lithium-ion battery, and made available when required.


In the process the electric motor assists the engine braking effect of the internal combustion engine in two smooth, seamless stages: In stage one, on the overrun with no braking action, the electric motor acts as a generator and begins to recuperate energy. Stage two commences as soon as the driver lightly operates the brake pedal: the generator output is then increased proportionally, and perceived as heavier deceleration by the driver. Only when more brake pedal pressure is applied are the wheel brakes activated in addition to recuperation. In this way more electrical energy can be generated, while saving wear and tear on the hydraulic braking system at the same time. To make the best possible use of this double benefit, Mercedes engineers also developed a new braking system with a new brake pedal module for the Mercedes-Benz S400 BlueHYBRID.
Cleverly located control electronics
Dedicated control electronics are required to operate the 3-phase AC electric motor in the 120-Volt high-voltage DC network. The current converter is accommodated in the space formerly occupied by the starter. As the control electronics heat up as a result of electric currents measuring up to 150 amps, the system is equipped with its own, additional low-temperature cooling circuit.
Mercedes-Benz engineers have accommodated the transformer in the right front wheel arch, where it facilitates the exchange of energy between the 120-Volt high-voltage network and the 12-Volt onboard network - and also allows the option of emergency starting with jump leads if the standard battery should lose its charge. To ensure a consistently high level of electrical efficiency, the transformer is likewise cooled by a low-temperature circuit. The 12-Volt lead/acid battery is installed in the boot, and not only supplies the standard consumers but also the monitoring system for the high-voltage components with energy. Thanks to its interaction with the lithium-ion battery, it is considerably smaller in size and lighter than usual.
Tried-and-tested automatic transmission with a new configuration


Mercedes-Benz developers also adapted the well-proven 7G-TRONIC automatic transmission to suit the hybrid drive, with newly programmed software for the transmission management system. A newly developed auxiliary oil pump ensures reliable lubrication of the transmission even during phases when the internal combustion engine is switched off.
This complex system is managed by the modified high-performance engine control unit. This incorporates extensive functions, and distinguishes between operating conditions such as city traffic, rural journeys, motorway driving or slow manoeuvring.
Hybrid status is shown in the instrument cluster
The driver is also able to monitor the status of the hybrid drive system visually. The instrument cluster has a separate, centrally positioned, display showing the energy flow during boost and recuperation phases, as well as the battery charge status.
Seven-stage safety concept in addition to the Mercedes-Benz standard
As is usual at Mercedes-Benz, the development engineers gave safety aspects their very special attention. Know-how incorporated into the series-production car included long years of Daimler research experience with fuel-cell technology. The challenge lay in not only complying with all the worldwide and in-house legal crash test requirements, but also in ensuring the greatest possible safety for the electrical components. This safety system already applies in production, includes workshop personnel during servicing and maintenance, and also takes the emergency services into account when passengers need to be recovered following an accident.
Accordingly the hybrid technology of the Mercedes-Benz S400 BlueHYBRID is equipped with an extensive 7-stage safety concept.
In the first stage all the wiring is colour-coded to eliminate confusion, and marked with safety instructions. This prevents assembly errors in production, and makes the regular quality checks easier to carry out.The second stage comprises comprehensive contact protection for the entire system by means of generous insulation and newly developed, dedicated connectors.As part of the third stage, the world's first lithium-ion battery to be used in a series-production model has been given a whole package of carefully coordinated safety measures. This innovative battery is accommodated in a high-strength steel housing, and also secured in place. Bedding the battery cells in a special gel effectively dampens any jolts and knocks. There is also a blow-off vent with a rupture disc and a separate cooling circuit. An internal electronic controller continuously monitors the safety requirements and immediately signals any malfunctions.The fourth stage of the safety concept includes separation of the battery terminals, individual safety-wiring for all high-voltage components and continuous monitoring by multiple interlock switches. This means that all high-voltage components are connected by an electric loop. In the event of a malfunction the high-voltage system is automatically switched off.Active discharging of the high-voltage system as soon as the ignition is switched to "Off", or in the event of a malfunction, is part of the fifth stage.During an accident, the high-voltage system is completely switched off within fractions of a second (stage six).As the seventh and last stage, the system is continuously monitored for short circuits.Thanks to its compact dimensions and modular design, the additional weight of the overall system is only 75 kilograms - including the comprehensive safety systems. The superior driving experience for which a Mercedes is known is therefore ensured by this trailblazing and very versatile technology, which can be used for practically all Mercedes-Benz model series. Moreover, the payload remains unchanged at 595 kilograms.

The intelligent high-performance engine management system responds very sensitively to different driving conditions, and optimally configures the drive system for the relevant application, ensuring that both fuel consumption and emissions are kept to the lowest possible level.
At standstill the petrol engine is usually switched off, and therefore consumes no fuel. The electric drive of the refrigerant compressor and steering servo pump allows uninterrupted operation of the air conditioning and power steering. Comfort is in no way compromised, and is at the same high level as in all S-Class models.
Moving off and acceleratingaway gently remains a smooth and comfortable procedure. A driver who kicks down the accelerator for a brisk start benefits from the boost function of the electric motor, which produces considerably more dynamic acceleration.
At constant speedsthe intelligent electronics recognise situations such as relaxed motorway stretches, and automatically adjust the load point of the internal combustion engine to achieve a lower specific fuel consumption, thereby helping to save fuel and reduce emissions.
When rolling to a stopthe recuperation function is activated as soon as the drive is interrupted in any way (foot off the accelerator, engine braking). Once the vehicle speed falls below 15 km/h, the petrol engine is automatically switched off.

If the driver brakes using the brake pedal, the electric motor initially begins to convert the vehicle's kinetic energy into electrical energy. In this case the electric motor acts as a generator, storing the kinetic energy as electrical energy in the lithium-ion battery. This process feels like a stronger engine braking effect to the driver. The conventional disc brakes at the wheels are not yet employed, saving wear and tear. The disc brakes are only activated if the driver applies heavy pressure to the brake pedal, braking the car together with the engine brake and recuperation.
Once the driver selects "R" (reverse) in the 7G-TRONIC automatic transmission when manoeuvring, this automatically activates the Manoeuvring mode and prevents the start/stop function from switching off the engine at short, frequent intervals.
The advantages of the hybrid drive system really come into their own in city traffic, with frequent stops at red traffic lights. Already switching off the petrol engine as the car frequently coasts to a stop significantly lowers the fuel consumption and emissions, while the long recuperation phases increase the battery charge. The electric motor ensures particularly comfortable and rapid restarting when the start/stop function is active.
On rural roadsthere are frequent changes between boost, constant speed and recuperation phases. Depending on the nature of the route, large quantities of recuperation energy are available to reduce fuel consumption and emissions. The more braking and acceleration phases there are, the better: uphill and downhill gradients, as well as winding, dynamic stretches, make for the largest savings.
The hybrid effect is inherently less important on motorways, however thanks to specific modifications to the V6 petrol engine and the 7G-TRONIC automatic transmission, the driver is also able to achieve significant fuel savings and correspondingly lower emissions on fast road stretches like these.
The Mercedes-Benz S400 BlueHYBRID is produced at the Sindelfingenplant, together with the other S-Class models. The petrol engine, 7G-TRONIC automatic transmission and electric motor are first put together to form a hybrid module, then delivered to the production line as a unit. The market launch in western Europe is planned for June 2009; China is expected to follow in August 2009 and the USA in September 2009.

Modular technologies for the environmentally friendly future of the premium car
The new S400 BlueHYBRID exemplifies the strategy of Mercedes-Benz, whose declared aim is to offer the brand's customers economical and environmentally compatible premium cars - without compromising in terms of typical brand attributes such as safety, comfort and a superior driving experience.
Major areas of development focus include modular drive technologies, which are used on a stand-alone basis or in combination depending on the vehicle class, operating profile and customer requirements - Mercedes-Benz has already described how this applies to the product portfolio in its "Road to the Future". In this context Mercedes-Benz also provides an outlook on the future of the internal combustion engine, with the innovative DIESOTTO engine in the Mercedes-Benz F700 research car.

E-Class Coupe

The 2009 Geneva Motor Show sees the comeback of an intriguing product idea with the Mercedes-Benz E-Class Coupé. Just three months after the presentation of the E-Class Saloon, the brand is launching a 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 Mercedes-Benz 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 Coupé 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 Mercedes-Benz E-Class Coupé's standard-fit AGILITY CONTROL suspension adjusts automatically to the current driving situation. It combines driving enjoyment and excellent handling with maximum comfort.The new Mercedes-Benz E-Class Coupé will be in UK showrooms from June 2009.

The new Coupé offers all the technical innovations of the new Mercedes-Benz 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 and an automatic emergency braking system are also 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 53.3 mpg emits 139 grams of CO2 per kilometre, making it one of the most economical vehicles in its class.

The exemplary, 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 Mercedes-Benz E-Class 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 lean build give it a racier and more dynamic presence.

Newly developed seats with a sporty design

The seats of the Mercedes-Benz E-Class Coupé are new developments whose design and technology 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 electro pneumatically 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 are standard on the SE, and active ventilation available is available as an optional extra. The 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 are standard on the Sport model. 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 improved 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 turbo charging, precise piezo injectors and the latest common-rail technology. The engine has an output of 204 hp and develops a maximum torque of 500 Nm 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 returning 53.3 mpg (combined NEDC consumption, provisional figure). This corresponds to a carbon dioxide emission level of 139 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 231 hp (previously: 224 hp) and returns 41.5 mpg (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 Mercedes-Benz E-Class Coupé points the way: the power plant at work under the bonnet of the E 250 CGI BlueEFFICIENCY Coupé is a newly developed four-cylinder direct-injection unit with 204 hp and a five-speed automatic transmission as standard. This engine returns 40.4 mpg (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 (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 292 hp - an extra 20 hp - and consumes about 14 percent less fuel than the previous V6 engine: its combined fuel economy is 32.5 mpg. This corresponds to 203 grams of CO2 per kilometre.

In the top-of-the-range model, the E 500 Coupé, the muscular V8 engine with 388 hp and 530 Nm of torque offers the performance characteristics of a sports car. Mercedes engineers have enhanced details of the eight-cylinder unit, to returns 25.9 mpg (combined NEDC consumption). All the engines in the new E-Class Coupés meet the EU5 exhaust emission standard.

Safety: sensors, radar and cameras for safer 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 Mercedes-Benz 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.

Drowsiness is 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 Mercedes 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 has 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 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 Mercedes-Benz 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. This is standard on the Sport and optional on the SE.

Automatic emergency braking when a collision is imminent

The well-proven assistance systems from the Mercedes-Benz S-Class which help to prevent rear-end collisions are now available for the Mercedes-Benz 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 PLUS system; 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 thePRE-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 Mercedes-Benz 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 knee bag for the driver and window bags. 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 alloy 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 body shell of the Mercedes-Benz 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 Mercedes-Benz 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 (Standard on the E500 Coupé and optional on the Sport model line) 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 standard on the Sport model line.

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 indication 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 inthree 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 Mercedes-Benz 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 conceptfrom 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 Mercedes 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/DVD player, 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 multimedia system benefit from additional functions: a Europe-wide hard-disc navigation system, a DVD changer, the Music Register (storage for about 1000 music tracks), a media interface for connecting external MP3 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, players and a tuner for digital radio reception. Navigation 50 will also be optional on the Mercedes-Benz E-Class Coupé providing a compromise between Audio 20 and COMAND offering a head unit with full colour mapping as well as the media interface.

Model range: individuality through variety

With a line-up of five engines in the UK, three suspension variants, a wide choice of colours, five different wheel/tyre combinations and many optional extras, the new Mercedes-Benz 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 SE and SPORT model lines.

These not only offer different upholsteries and items of trim, but are complete configuration packages designed to create a completely different 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 Sport model line clearly focuses on agility and performance potential. AMG body styling 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.
