They epitomise all that a refined, sporty car should be, their technology, aesthetics and appointments forming a stylish and harmonious whole. They are cars for people who believe in making their dreams come true.  Mercedes coupés have always been offered in a number of different vehicle categories - and in different forms. There have been city coupés, touring coupés, combination coupés, sports coupés … For all their differences, these two-door models had one important factor in common: the Stuttgart-based firm has always made a point of creating coupés which are much more than just saloon models with a shorter rear section. In fact, Mercedes coupés have always been clearly identifiable as distinct models in their own right - as automotive personalities with their own charisma and their own character. It is this recipe for success that has made all Mercedes coupés, past and present, automotive classics which are sought-after collector’s items. Coupé version closely related to the saloon The new Mercedes two-door model, which reaches the market in May 2009, follows in the tracks of its successful predecessors and represents a technical and stylistic high point in the history of the E-Class coupés. Although the new model continues to emphasise its own, distinct identity, the genes of the Saloon stand out more prominently than ever and establish a closer relationship between the two models. This connection is underlined by the reappearance of the "E" in the model designation.  Comfort, safety and agilityThe passion people feel for a Mercedes coupé is aroused above all by the design - the lines, the colours, the choice of materials and appointments. Take the fully  The successful Mercedes coupé vehicle concept is matched by the high-specification equipment line-up which Mercedes-Benz has put together for the new two-door model and which meets the same high standards of exclusivity and individuality set for all other aspects of the E-Class Coupé. No other coupé in this vehicle category offers such a comprehensive range of equipment as standard. The line-up includes:
 Choice of two standard-fit interior design and equipment concepts ELEGANCE interior concept
AVANTGARDE interior concept
 The sporty aspect of the E-Class Coupé can be reinforced with the optional AMG sports package. This comprises additional high-specification appointments details as well as a special front and rear design treatment which gives the car a distinctive look:
High-tech systems on the options list  The E-Class Coupé sets new standards among coupés with its advanced assistance systems which represent a distinct plus in terms of safety, comfort and driving enjoyment. The selected items listed here provide an indication of the scope of the factory-fitted optional extras which can be specified:
---- DesignThe new E-Class Coupé from Mercedes-Benz aims straight at the senses – it takes only a moment to be captured by the charisma of this sports car. Its taut lines, powerful muscles and sharp, arrow-shaped front speak directly to the emotions and promise compelling driving enjoyment.  The proud tradition of Mercedes-Benz coupés continues with the latest two-door model from Stuttgart. The newcomer features styling elements which give Mercedes-Benz coupés their unmistakable identity: elements such as the side window treatment which has no B-pillar to interrupt it and features fully retractable windows, or the characteristic sports radiator grille with the large central star. At the same time, this model points the way to the future with an exciting, contemporary design idiom. The powerful styling accentuates the sleek, flowing lines Viewed from the side, the two-door model impresses with its clean proportions and its perfect coupé profile: long bonnet, wide door, high shoulderline with elongated side window treatment, lowered roof line and a short rear overhang. A powerful, muscular form which is integrated in the side wall over the rear axle and a slender, sweeping C-pillar add to the stylish appearance and embody agility and athleticism.  Arrow-shaped front and dominant radiator grilleFrom the front bumper to the radiator grille to the bonnet, the pronounced arrow shape of the front section emphasises the sporty character of the Coupé. 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 a dominant, expressive statement of the brand’s identity. 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 Coupé: the rear wings spanning the rear axle are sculpted to create a powerful, muscular form which visually enhances the vehicle’s width. The distinctive feature line - a characteristic Mercedes styling element - is continued skilfully around the back of the vehicle and into the tail lights, thereby forming a link between front and rear. New paint finishes with effect pigments The range of paint finishes comprises twelve colours, five of which are new. A high aluminium content and effect pigments provide the basis for the new stannite grey. Depending on the light incidence, it acquires a green to beige tinge and brings out the forms of the new E-Class Coupé to particularly good effect. Interior with sporty lines and high perceived valueIn 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.  The light coming through the continuous glass roof creates a special ambienceLight has an important positive effect on people’s sense of well-being. This is why the interior mirror housing contains an ambient lighting source as well as reading lights for the driver and front passenger. A particularly pleasant lighting ambience is created by the optional panoramic sliding roof featuring heat-insulating glass which forms a continuous visual element extending from the windscreen to the rear window. This feature makes the interior brighter and even more appealing but can be covered by means of an electrically operated roller blind when required. Sporty individual seats for the rear passengers, tooThe thoroughly sporty look and feel of the new E-Class Coupé is underlined by the sporty design of the seats which also take the form of individual seats for the rear passengers. Although the Coupé is deliberately designed as a four-seater, the rear backrests still offer a 1/3 to 2/3 split folding function. 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. 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 Coupé. The sporty two-door model is equipped as standard with brushed aluminium trim elements 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 elements have a thin chrome strip along their upper edge. ---- Active safetyPreventing traffic accidents is at the heart of Mercedes-Benz’s commitment to safety. This is why the engineers in Sindelfingen are dedicated to advancing the development of sophisticated assistance systems which warn and assist the driver in critical situations and can act autonomously if there is acute danger. ABS, ESP® and Brake Assist were the first technologies of this kind; their positive effect has since been confirmed by accident statistics.  The new or modified driver assistance systems in the E-Class Coupé are basedon state-of-the-art radar, camera and sensor technology. They are specially configured to help reduce the number of accidents caused by being too close to the vehicle in front, drowsiness and darkness. Drowsiness detection: steering behaviour as the key indicator Four years of development and testing work on the ATTENTION ASSIST system revealed steering behaviour to be an extremely meaningful indicator of drowsiness. In the tests involving over 670 drivers, the Mercedes scientists determined that drowsy drivers have trouble steering a precise course in their lane, making minor steering errorsthat are often corrected quickly and abruptly. This effect occurs at an early stage when drowsiness kicks in - often before the dangerous microsleep phase. ATTENTION ASSIST is active at speeds of between 80 and 180 km/h. Highbeam Assist: optimum light distribution in every driving situationDriving can be particularly dangerous at night. Although there is far less traffic on the road in the evening and at night, almost 40 percent of all fatal traffic accidents occur during the hours of darkness. One of the main causes of accidents is the driver’s lack of visibility. According to a study carried out by the TÜV (German technical inspection authorities), around 23,000 serious accidents involving 1200 deaths could be avoided if all cars were fitted with powerful bi-xenon headlamps.  Mercedes-Benz has used this headlamp technology since as far back as 1999. Now the Stuttgart-based brand is unveiling a further innovation in the shape of optionally available Adaptive Highbeam Assist. This innovative system adjusts the range of the headlamps automatically based on the distance to oncoming vehicles or moving vehicles in front of the car with their lights on. Consequently, the best possible headlamp range is always selected, allowing the driver to see the course of the road, pedestrians or danger spots more clearly and at an earlier stage. The low-beam range can therefore be increased from around 65 to up to 300 metres - without dazzling other motorists.  Adaptive Highbeam Assist additionally takes into account the steering angle in order to dim the headlamps on tight bends. If the road ahead is clear, the system performs a gradual transition to high-beam mode. Intelligent Light System: five light functions with bi-xenon headlamps The Intelligent Light System is another innovation in lighting technology available for the new E-Class Coupé. This optional extra provides five different light functions designed specifically for typical driving situations and weather conditions:
 The new E-Class Coupé is fitted with halogen headlamps as standard. For low beam, the Mercedes engineers have developed a sophisticated projection system, which is housed in the two larger lamps at the front end. The inner headlamps, based on reflection technology, provide the high beam and serve as side lights. Headlamp Assist, which switches on the headlamps automatically when it is raining, at dusk/dawn, in the dark and when entering a tunnel, is likewise specified as standard. Tail lights: LEDs for every functionMercedes-Benz also specifies LEDs as standard for the indicators, tail lights, brake lights and rear fog light in the rear light clusters. One of the advantages of LEDs is their quick response, meaning that drivers behind receive an earlier warning if the Coupé’s brakes are applied in the event of danger. What’s more, this technology allows a new and unmistakable night design.  Like many of the latest Mercedes passenger cars, the new Mercedes Coupé is fitted with adaptive brake lights, which flash four times as fast as the hazard warning lights during an emergency stop and, therefore, provide an extremely effective warning for drivers behind if a head-to-tail collision is imminent. Speed Limit Assist: speed limit displayed in the instrument clusterAs well as being used by Adaptive Highbeam Assist, the electronic camera located on the inside of the windscreen provides the image information for Speed Limit Assist (optional). This newly developed system reminds drivers of the speed limit currently in force by displaying it in the instrument cluster - a further contribution towards preventing accidents.  Thanks to the huge strides forward made in computer-based image-processing technology, Speed Limit Assist is able to work in real time, analysing the images within a fraction of a second so as to provide the driver with the required information practically instantaneously. Plus it makes no difference whether the speed-limit sign is at the side of the road or on a gantry above the road. The system is therefore able to react to variable speed limits (often indicated on gantries) as well as temporarily erected speed-limit signs, for example at road works. DISTRONIC PLUS: radar systems to help prevent head-to-tail collisionsRadar - for monitoring events in front of and behind the car as well as warning the driver in critical situations - is a tried-and-trusted technology introduced at Mercedes-Benz in 1998. It plays an important part in helping to prevent accidents, as shown by an analysis based on representative accident-research data. This technology can prevent a fifth of all head-to-tail crashes in Germany alone. On motorways, the accident rate can be reduced by as much as around 36 percent. For the new E-Class Coupé, Mercedes-Benz offers a radar-based assistance system in the shape of DISTRONIC PLUS (optional), which also incorporates Brake Assist PLUS.  DISTRONIC PLUSproximity control operates at speeds of between 0 and 200 km/h: it keeps the car a set distance behind the vehicle in front, applies the brakes as required and can even bring the car to a complete halt, depending on the traffic situation. If the gap to the vehicle in front narrows too quickly, the system gives the driver an audible warning and, as soon as this first warning signal sounds, automatically calculates the brake pressure required to prevent a collision in this situation.  PRE-SAFE® Brake: autonomous braking as "electronic crumple zone"Accident research shows that drivers do not always react as quickly as necessary at critical moments - for example because they are distracted and therefore do not recognise the immediate danger of a head-to-tail collision, or because they fail to heed the warning signals given by an assistance system. The PRE-SAFE® Brake intervenes in situations such as these by braking the car automatically. It does so in two stages: around 1.6 seconds before the calculated impact point - after three audible warning signals - the system initiates partial braking autonomously and decelerates the car with around 40 percent of the maximum braking power (approx 4 m/s²) as well as activating the reversible PRE-SAFE® occupant protection systems as a precaution.  If the driver fails to react, however, even after automatic partial braking, the PRE‑SAFE®Brake activates the maximum braking power around 0.6 seconds before the now unavoidable collision. This emergency braking can reduce the severity of the impact by a substantial margin. Effect: impact speed reduced by 16 km/h on averageRealistic tests carried out by the Mercedes engineers have revealed that autonomous PRE-SAFE® braking reduces the impact speed by 16 km/h on average. The system therefore acts like an "electronic crumple zone", offering the car occupants an even higher level of protection. Parking aid: ultrasonic measurement of parking spacesA newly developed system that can help drivers to park safely works on the basis of ultrasonic technology: sideways inclined sensors on the front bumper record the length of a parking space as the car drives past it (at a speed of up to 35 km/h), and indicate on the cockpit display whether the space is large enough to park in. After reverse gear has been engaged, instructions for safe parking appear on the display in the instrument cluster. The tried-and-trusted Mercedes PARKTRONIC system (optional extra), which uses LEDs and audible signals to indicate the distance between the Coupé and an obstacle or another vehicle when parking, is integrated in the Parking Guidance system. Aerodynamics: best cd figure of all series-production carsLike its Saloon counterpart, the new E-Class Coupé is exceptionally aerodynamic – one of the main reasons behind the high level of active safety and the low fuel consumption. The drag coefficient (cd figure) is as low as 0.24, depending on model, which is around eleven percent lower than the figure for the previous model, making the new E-Class Coupé the world’s most aerodynamic series-production car.  Further aerodynamically effective details displayed by the new E-Class include:
 The exterior mirrors also play a crucial role in enhancing perceptual safety as they improve the driver’s visibility in the rain. The mirror housings are designed so that any rainwater hitting them flows outwards in a narrow groove running around the outside so that it can drip off at a precisely defined point. As a consequence, the side windows remain largely clean, affording the driver an unimpeded view of the exterior mirror and the outside. The A-pillars likewise help to keep dirt away from the side windows as they feature special water guides where the rainwater hitting the windscreen is collected before being blown downwards as well as rearwards across the roof by the airflow. ---- Passive safetyIn the new E-Class Coupé, occupant protection actually begins in the phase leading up to a possible accident thanks to the Mercedes PRE-SAFE® invention, which is specified as standard for the two-door model. If there is a risk of an accident, the system activates protective measures as a precaution, allowing the seat belts and airbags to deploy with maximum effect in the event of a collision. This early accident detection is possible because PRE-SAFE® is an intelligent synergy of active and passive safety. It is linked to Brake Assist and the Electronic Stability Program (ESP®), whose sensors detect critical driving situations and send the relevant information to the electronic control units within a matter of milliseconds. PRE-SAFE® also uses these sensor data.  All PRE-SAFE®protective measures are reversible: if the accident is averted, the advance tensioning of the seat belts is halted automatically, and the occupants are able to reset the positions of the seats and the sunroof. The anticipatory occupant protection system is then ready for action again straightaway.  Analyses performed during crash tests show just how important and effective this safety system can be. In the case of precautionary belt tensioning, for example, the measures mean that the driver and front passenger are held in their seats in the best possible position and so do not move forwards as much before the impact, thus reducing the load exerted on the head and neck area. These tests showed that the head was subjected to around 30 per cent less stress, while the Mercedes engineers recorded a reduction of around 40 per cent in the neck area. Front-end structure: further enlarged crumple zone on four levelsCompared to the previous model series, the Mercedes engineers have enlarged the deformation zones substantially in the front and rear sections of the new E‑Class Coupé as well as improving the energy flows. The front crumple zone has four independently-acting impact levels, meaning that the forces can be distributed over a wide area while bypassing the passenger cell.  3) The subframe to which the engine, steering and front axle are attached also serves as an impact level in the event of a frontal collision. It is made of high-strength steel and, depending on the engine variant, can be connected to the newly developed floor side members by means of special supporting tubes. As a consequence, the subframe can deform in a predetermined manner and absorb energy in the event of a crash on the one hand and channel high impact forces straight into the vehicle floor on the other.  Side wall: two-shell construction with reinforcementsLike the designers, the body specialists and safety engineers at the Mercedes-Benz Technology Centre (MTC) in Sindelfingen played a major part in creating one of the new E-Class Coupé’s most attractive design features: the elegant side lines, along with the continuous strip of the side windows and the filigree roof pillars were only made possible thanks to a series of complex body manufacturing processes. All of which enables the Coupé to meet the most stringent of test requirements with respect to torsional stiffness and occupant protection, even though it has no upper B-pillars.  Likewise, high-strength panelling is welded into the (non-visible) B-pillars which, together with numerous other reinforcement measures, provides effective resistance in the event of a side impact. Below the dashboard, there is also a solid square section which is bolted to both the A-pillars. Materials: around 60 percent of all panels are made from high-strength steelThese examples show that, more so than ever before, Mercedes-Benz has given preference to ultra-high-strength steel alloys for the body construction because they offer maximum strength whilst minimising weight and, therefore, are essential for meeting the strict safety and durability requirements. Around two thirds of all the bodyshell panels for the new E-Class Coupé are made from these grades of steel. These ultra-high-strength alloys, which boast three to four times the tensile strength of conventional high-strength steel grades, account for around 20 percent of the weight (previous model: one percent). They are used in those areas where the material can be subjected to extreme stresses during an accident.  Mercedes-Benz’s intelligent material concept also involves the specifically targeted use of aluminium and plastic, both of which help to save weight above all. Hence the front end, bonnet, front wings and boot lid of the new Coupé are made from aluminium, while the front end is a hybrid constructionmade from sheet aluminium and fibreglass-reinforced plastic. The front single-section aluminium crash boxes are inserted into the side members and bolted to them at the side. The other front-end components are likewise bolted together and can therefore be replaced cost-effectively following an accident. Glass fibre matting-reinforced plastic has been used to produce the spare-wheel well. Passenger cell: custom-designed floor panels and robust load-bearing sectionsThe passenger cell of the new two-door model is a robust structure which is virtually immune to deformation and keeps the passengers’ survival space intact, even at high impact speeds, regardless of whether the collision is head-on, from the rear or from the side, or whether the vehicle rolls over. The use of high-strength steel and thicker panels plays as important a role here as the installation of additional load-bearing members.  The Mercedes engineers have also incorporated sturdy aluminium transverse sections - known as transmission tunnel braces - into the floor assembly. One is located beneath the transmission, and is designed to direct forces to the side of the vehicle facing away from the impact in the event of a side-on collision. The second forms a connection between the two side members. It likewise braces the floor assembly and is able to channel impact forces into the floor structure at an early stage following a side-on collision. Rear-end structure has successfully passed the toughest of crash testsMulti-piece side members and a robust crossmember made from ultra-high-strength steel form the key components of the rear-end structure. The rear side members are continuous, closed box sections with carefully graduated material thicknesses. These are able to absorb high forces, thereby making a decisive contribution to occupant safety in the event of a rear impact. The bolt-on flexible crossmember is manufactured using a flexible rolling process which likewise allows the material thickness to be varied as required. Accordingly, the material thickness on the outside of the crossmember - where impact loads are highest - is greater than on the inside. The new Coupé therefore also meets the world’s most stringent crash regulations where rear impact protection is concerned, for example the 80-km/h test in the US.  Typically for a Mercedes-Benz car, the fuel tank is located in a protected position beneath the rear seats, in other words ahead of the rear axle and, therefore, outside of the impact zone. Body torsional stiffness increased by around 24 percentAs well as being a major reason behind the high level of impact resistance, this intelligently designed bodyshell enhances ride comfort or, to be more precise, Restraint systems: seven airbags as standardWith seven airbags fitted as standard, not to mention four seat-belt tensioners and belt-force limiters as well as NECK-PRO crash-responsive head restraints for the driver and front passenger, the new E-Class Coupé offers an even more extensive package of safety equipment than its predecessor. The airbags, which can deploy in a matter of milliseconds in the event of an accident, include two adaptive airbags (for the driver and front passenger), a kneebag for the driver, two sidebags in the front-seat backrests and two large windowbags which extend from the A-pillar to the C‑pillar during a side impact. Plus the E-Class Coupé is the only coupé in this vehicle category to also offer the option of sidebags for the rear passengers. Crash-responsive head restraints for driver and front passenger NECK-PROis the name Mercedes-Benz has given to a crash-responsive head restraint whose development, like that of PRE-SAFE® and other Mercedes innovations, is based on analyses of real accidents. NECK-PRO is an effective means of reducing the risk of whiplash injuries during a rear-end collision. If the sensor system detects a rear-end collision with a defined impact severity, it releases pre-tensioned springs inside the head restraints, causing the head restraints to move forward by about 40 millimetres and upwards by 30 millimetres within a matter of milliseconds. Pedestrian protection: extensive raft of measures including Active BonnetThe protection of those road users who are most at risk has always been a top priority during the development of Mercedes passenger cars. Smooth-surfaced bodies, energy-absorbing bumpers, flush-mounted door handles, laminated-glass windscreens, folding exterior mirrors and recessed windscreen wipers are pedestrian-protection measures that have been features of Mercedes models for many years. But, as ever, another top priority for the safety engineers is accident prevention. So systems such as Brake Assist and the cornering light function play crucial roles. Fitting Brake Assist as standard alone has reduced the rate of serious accidents involving collisions between pedestrians and Mercedes passenger cars by 13 percent. The additional protective measures Mercedes-Benz has introduced for the E‑Class, including the new Coupé model, are based on these high standards. Top of the bill is an Active Bonnet, which enlarges the deformation area, reducing the risk of injury to pedestrians. This system, fitted as standard, includes three impact sensors in the front section as well as special bonnet hinges pretensioned and arrested by powerful springs. Upon impact with a pedestrian, the sensors send information to the electronic control unit which, in turn, activates two solenoids in the hinges instantaneously. These solenoids release the arresters so that the rear section of the bonnet is pushed upwards by 50 millimetres by means of spring force. It all takes just a fraction of a second. ---- InteriorAesthetics and ergonomic design - two of the main aims when Mercedes-Benz designs and develops car interiors. And the new E-Class Coupé is proof that the Sindelfingen designers and engineers are also masters of these disciplines. The team of designers has created an attractive, appealing interior by using sophisticated styling, fine materials and pleasant colours, while the engineers implemented new comfort- and enjoyment-enhancing ideas and concepts to perfect this "atmosphere of wellbeing". The end result is a unique symbiosis of aesthetics and technology.  Key factors that enable man and machine to exist in perfect harmony include the dimensions which determine spaciousness for the occupants: seat spacing, headroom, kneeroom, elbow width and shoulder width. In all of these areas, the new Mercedes Coupé is substantially larger than the preceding model: the body is 46 millimetres longer and 46 millimetres wider than previously, while the wheelbase has been increased by 45 millimetres to 2760 millimetres.  The overall boot capacity of 450 litres (as per the VDA measuring method) has been increased by 15 litres despite the far more extensive basic equipment package for the new E-Class Coupé. There are 25 litres of stowage space available in the compartment beneath the luggage-compartment floor. And the folding rear-seat backrests allow Mercedes customers to increase the load-carrying capacity depending on the transport task in hand as well as producing a practically flat load bay. Standard-fit load-securing rings enable items of luggage to be secured in place. Seats: sporty design and maximum comfortNewly developed seats, which reflect the sporty character of the Coupé in terms of both design and technology, offer the driver and front passenger hallmark Mercedes comfort. The standard-fit NECK PRO head restraints are integrated in the raised backrests.  The seats in the new E-Class Coupé have the largest fore/aft adjustment range in this market segment: 273 millimetres. The individual seat position can be adjusted in very small 4.5-millimetre stages and, therefore, is almost continuously variable, whereas the backrest inclination is fully continuously variable.
Standard equipment for the new Coupé includes a mechanical entry and exit aid for the rear passengers, called the Easy-Entry system. It is operated using a lever next to the head restraint, which initially tilts the seat backrest forwards. The seat can then be pushed forwards. Memory function: comfort-enhancing four-way lumbar supportThe fully electrically adjustable seats for the driver and front passenger, which Mercedes-Benz supplies as optional extras, are even easier to use. In this case, the fore/aft position, seat cushion angle, head restraint, steering column and exterior mirrors can be adjusted by electric motors in addition to the seat height and backrest angle. In addition to this, the Easy-Entry system is operated with the assistance of the electric motors.  If the Memory package (optional) is specified, three individual positions can be stored for the fully electrically adjustable front seats as well as for the steering wheel and the exterior mirrors. In this case, a touch of a button on the inner door lining is all it takes to move the seats, steering wheel and exterior mirrors to their programmed positions automatically. When the driver removes the electronic ignition key, the steering wheel can be moved upwards to make it even easier to get out of the car. The steering wheel then remains in this position until the ignition key is re-inserted, providing the driver with more legroom when getting back into the car as well. Seat climate: four ventilators for active ventilation When developing seats, the Mercedes specialists look not only at the classic comfort features like springing and damping but also at occupant wellbeing as a whole, including what is referred to as seat climate. The materials used in a Mercedes seat, and its internal structure, must be designed to ensure comfort under all weather and temperature conditions. In the case of the new Coupé seats, this is achieved by using breathable composite seat materials and high-quality fabric or leather surface upholstery. Multicontour seats: air chambers in the backrests and seat cushionsThe newly developed multicontour seats allow the driver and front passenger to adapt the contours of the seat to suit their anatomy or personal preferences thanks to inflatable air chambers in the side bolsters of the backrest, in the lumbar region and at the front edge of the seat cushion. One special attribute of the new multicontour seat is the function for pneumatically adjusting the seat cushion length. The front air cushion increases the seat cushion length at the push of a button, allowing occupants to relax their legs and ensuring good blood circulation.  Rear: comfortable individual seats with folding backrestsFor the rear passengers, there are two comfortable individual seats with integral head restraints whose distinctively contoured foam upholstery ensures a high level of comfort and excellent lateral support. The asymmetrically divided rear-seat backrests can be folded forwards individually or together to increase the boot capacity. Between the individual rear seats is a spacious stowage compartment incorporating two cup holders under a retractable cover – suitable for various cup, can and bottle formats. Climate control: THERMOTRONIC with three individual climate modesComfort is all about highly individual preferences. Which is why it is important for cars to offer their occupants a wide range of personalisation options. The new Coupé meets this requirement, not only in terms of suspension tuning and seat adjustability, but also when it comes to climate comfort. In "Diffuse"mode, for example, the THERMOTRONIC system operates with a low air speed and distributes the air over a wide area so that there are fewer draughts. This is the purpose of the automatically controlled, upwards inclined diffuse nozzle in the centre of the dashboard. In "Focus" mode, meanwhile, the air outlets in the centre area of the dashboard are used for the most part, meeting the need for a direct flow of a larger quantity of air.  Finally, the THERMOTRONIC system is equipped with a separate control panel at the rear of the tunnel console, allowing the rear passengers to select their ideal temperature. Another highlight of the THERMOTRONIC system is the residual heat function: pressing the "Rest" button heats or ventilates the interior for around 30 minutes when the engine is switched off. Heating and cooling output increased by five percentThe THERMATIC and THERMOTRONIC systems have received a boost in both heating and cooling output. The heating output has been increased by around five percent to eleven kilowatts, equivalent to the capacity of the central heating system in a modern family home. In the diesel models, a heat exchanger with six integral PTC heating elements (PTC = Positive Temperature Coefficient) is also activated when the outside temperature falls below a certain level in order to boost the effect of the main heat exchanger with an electrical output of around 1200 watts. The assistance from the PTC heater is necessary due to the high thermal efficiency of today’s CDI engines, which is precisely what makes them so economical and means that they release considerably less heat to the coolant under partial load conditions than conventional engines.  The interior is cooled rapidly by an air-conditioning unit with an output of around 8.4 kilowatts - some five percent more than the unit used in the predecessor model. Its compressor is variable in operation, allowing on-demand, i.e. economical, operation of the air conditioning. The compressor is controlled by a solenoid valve which varies the swept volume. Air cleaning: fine-dust particulate filter fitted as standardA large, hermetically sealed fine-dust combination filter, fitted as standard, ensures that the air entering the interior is clean. It is 96 to 98 percent efficient at filtering out particles between five and ten micrometres in size and 100-percent efficient when it comes to removing ten-micrometre particles. Thanks to the activated-charcoal lining, gaseous substances, which are the cause of unpleasant odours, can also be filtered out. This filter is active on a permanent basis - even in air recirculation mode. Dashboard: form and function in perfect harmony As an option, the horizontally divided dashboard specially designed for the E‑Class Coupé can be ordered with a two-tone design: while the upper section and the centre console are finished in a darker shade, the lighter contrasting colour used for the knee bolster, glove compartment lid and tunnel console makes these areas really stand out. The surface of the dashboard is made from a polyurethane skin with additional padding. This sophisticated production process allows both small radii and precise edges, plus it ensures a pleasant feel.  Centre console: command centre for the infotainment and automatic climate control systemsThe centre console blends in harmoniously with the dashboard form and colour concept. This is where the controls for the infotainment system and the optionally available car phone are located, just below the air outlets. Beneath these, the buttons for the seat heating, seat ventilation, rear window blind and other optional extras are demarcated by a discreet chrome strip. The lower section of the centre console houses the controls for the standard-fit automatic climate control system. Controls: proven concept from the S-Class Fewer switches but more functions. A simple way of expressing the credo of sophisticated automotive controls at Mercedes-Benz, which are based on four basic principles: Multifunction steering wheel: twelve buttons for key functions The buttons on the multicontour steering wheel are linked to the central display in the instrument cluster and merely need to be tapped with the thumbs to gain fast access to a wide range of information displayed right in front of the driver’s eyes. The driver uses the buttons on the left-hand side to mark one of the main menus on the central display (in horizontal direction) and to activate the desired submenu (in vertical direction). Each selection or setting is accepted by pressing the "OK" button, while the "Return" button is used to return quickly to the next-highest menu level. In the centre of the speedometer, there is a two-section central display (4.5-inch) with white backlighting, whose upper section can be used to show a variety of information such as mileage, range, oil level, route distance, driving time, current fuel consumption, average fuel consumption and average car speed. If a navigation system is installed (optional), this area of the display also provides information about the current route. This display can also be used in conjunction with the buttons on the multifunction steering wheel to select radio stations, phone numbers and around 50 individual settings. Colour display: view of all the infotainment functions In the centre of the dashboard - where it can be easily seen by the driver and the front passenger - a large colour display in 16:9 format provides information about all the infotainment system functions. There are two versions of this sophisticated AM-TFT(Active Matrix Thin Film Transistor) display available, depending on the equipment specified: a 5.8-inch version for the Audio 20 and Audio 50 APS devices or a high-resolution 7.0-inch version for COMAND APS.  The AUDIO 50 APS infotainment system, available as an option, is an all-in-one device featuring a combination of car radio, DVD player and Europe-wide navigation system. The radio functions and the options for linking with other systems are the same as for the Audio 20 system. Mercedes customers who opt for the version with integral six-disc DVDchanger also receive the LINGUATRONIC voice-operated control system. COMAND APS: multimedia system with even more functionsThe COMAND APS multimedia system includes a DVDplayer for audio and video as well as a Europe-wide navigation system whose data are stored on a 40‑gigabyte hard drive, allowing extremely fast access to the navigation data and, compared to DVD-based navigation, even faster route calculations. The high-resolution map appears on the 7.0-inch colour display in the centre of the dashboard and provides useful additional information. By way of example, the map shows the outlines of prominent buildings along the route to aid orientation. Voice-operated control: whole-word voice input for navigation, telephone and radioMercedes-Benz is acknowledged as one of the inventors of modern voice-operated control systems. And the LINGUATRONIC voice-operated control system has benefitted from continuous further development in recent years. The navigation system in the E-Class Coupé can be operated by entering whole words, for example: the driver no longer needs to spell out the names of countries, towns or roads, but is able to speak them as whole words. The voice control system is just as convenient when selecting radio stations or entries in the telephone directory: all the stored names can be called up without any prior voice input training.
---- Drive systemWith its newly developed direct-injection diesel and petrol engines, Mercedes-Benz has taken further major strides forward in its quest to reduce both fuel consumption and exhaust emissions - without compromising on agility and driving enjoyment.  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 likewise new E 250 CGI BlueEFFICIENCY Coupé model with direct petrol injection has a displacement of 1.8 litres and an output of 150 kW/204 hp yet consumes a mere 7.2 litres of premium unleaded petrol per 100 kilometres (provisional NEDC combined figure) - around one litre per 100 kilometres (12 percent) less than the previous four-cylinder engine (135 kW/184 hp) with conventional fuel injection and a supercharger. The CO2 emissions of the direct-injection model have been cut to 167 grams per kilometre. Diesel engines: new four-cylinder unit featuring state-of-the-art common-rail technologyAs well as being economical and ecofriendly, the four-cylinder CDI engine impresses with its exceptional agility, effortlessly superior power delivery and exemplary refinement. The former is reflected in the performance figures: the new E 250 CDI BlueEFFICIENCY Coupé needs 7.4 seconds to accelerate from 0 to 100 km/h.  The engine is part of a new series of four-cylinder powerplants, which sees Mercedes-Benz introducing the fourth generation of its tried-and-trusted common-rail direct-injection units into series production. One of its hallmarks is a 400-bar increase in the maximum rail pressure, which now stands at 2000 bar. 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 reduction in untreated emissions.  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. Torque: two-stage turbocharging for exceptional pulling powerThe new diesel engine in the E 250 CDIBlueEFFICIENCY Coupé model marks the debut of two-stage turbocharging in a series-production diesel engine for Mercedes-Benz passenger cars. 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.  As the engine speed increases, the charge-pressure control flap opens. 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.  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 up to 140 degrees Kelvin so that a larger volume of air can enter the combustion chambers. Cooled exhaust gas recirculation to reduce NOx emissionsThe 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. Pedestrian protection: 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 chain drive.  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 and enhancing the turbocharger with a more efficient EGR cooling zone, switchable bypass duct, ceramic glow system, modified injection nozzles and optimised air ducting. Petrol engines: new four-cylinder unit with direct injectionCGIappears at the end of the model designation of the four- and six-cylinder petrol engines for the new E-Class Coupé, signifying that Mercedes-Benz uses  The four-cylinder engine is made almost entirely of aluminium: the crankcase is made of diecast 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. Thermal management: coolant circulation based on engine temperatureThe Mercedes engineers have paid special attention to the engine’s warm-up governor because also has a major effect on 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. Direct injection: pressure of up to 140 bar and new multi-hole injectors 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. Comfort-enhancing measure: balancer in the crankcase 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 that are caused by the motion of the pistons, for example, which 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. Six-cylinder engine: CGItechnology with spray-guided direct petrol injectionThe new E 350 CGIBlueEFFICIENCY Coupé is powered by the world’s first petrol engine with 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 8.5 litres per 100 kilo-metres (NEDC combined figure), which is 14 percent lower than the figure for the previous model, whose V6 engine featured port injection. These exemplary performance and fuel-consumption figures are achieved using cost-efficient premium unleaded petrol (RON 95). The seven-speed automatic transmission is fitted as standard. Mode of operation: stratified-charge mode, even at higher engine speeds 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 vastly improving mixture formation, combustion and consumption.  The combustion process with several injections in succession per combustion cycle developed by Mercedes-Benz 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. Precision-modified eight-cylinder engine The eight-cylinder unit in the E 500 Coupé - the flagship powerplant in the new generation of Mercedes-Benz V engines - provides 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 Coupé, which is equipped with the 7G-TRONIC 7-speed automatic transmission as standard: 0 to 100 km/h: 5.2 seconds Modified manual transmission and consumption-optimised automaticThe 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 Coupé with a modified transmission which, thanks to more effective gearing and a newly developed dual-mass flywheel, is capable of transmitting the peak torque of 500 Nm with the utmost reliability. 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 four-cylinder CDI Coupé (standard for the E 250 CGI) has likewise been precision-modified by the Mercedes engineers and features a newly developed converter that reduces the hydraulic losses and, therefore, operates even more fuel-efficiently than previously. In "C" mode, the transmission meets the most stringent of requirements in terms of fuel consumption, comfort and output, while "S" mode offers a more sportier configuration with an appropriately adapted gear-change strategy and accelerator pedal characteristic. Optional extras for the AMG Sports package include "M" mode, which has been specially configured for the keenest of drivers. ---- Chassis and suspensionThe newly developed AGILITY CONTROL suspension with standard-fit amplitude-dependent damping system forms the basis for the further enhanced ride comfort and agile handling of the E-Class Coupé. The shock absorbers adapt to the current driving situation, reducing the damping forces automatically when driving normally with low shock-absorber impulses and increasing the forces up to the maximum as required when cornering at speed or performing evasive manoeuvres. In this way, the chassis and suspension meet stringent requirements in terms of road roar, tyre vibration and agility - without ever compro-mising on active safety. What’s more, the longer wheelbase (an extra 45 millimetres), wider track (an extra 33 and 70 millimetres respectively) as well as the positioning of the engine low down and far towards the rear make a fundamental contribution to the new, agile driving experience by producing a favourable centre of gravity. The even axle load distribution ensures an almost perfect balance between the front and rear axles, as well as improved traction and handling stability. Shock absorbers: adjustment of the damping forces in line with the current driving situationThe AGILITY CONTROL shock absorber system - fitted as standard - is purely hydromechanical and requires no sensors or electronics. The core components are a bypass channel in the shock absorber’s piston pin and a control piston moving within a separate oil chamber. When linear travel of the shock absorber is low, the control piston forces oil through the bypass channel to produce a significantly smaller damping force at the actual damper valve. The resulting, "softer" shock absorber characteristic translates into a high level of ride comfort. If the excitation of the shock absorber is greater, the control piston moves to its limit position so that oil ceases flowing through the bypass duct, meaning that the full damping force is available.  Mercedes-Benz has enhanced the three-link front suspension with McPherson struts in a number of different respects, achieving excellent results in terms of ride comfort in particular. In the interests of favourable axle kinematics, superior vibration characteristics and enhanced safety, the lower link level consists of two separate elements which act as torque and cross struts. As well as offering more precise wheel location, this design has the particular advantage of compensating vibrations caused by tyre imbalance and fluctuating braking forces better than rigid wishbones. It also provides longer deformation paths in the event of a frontal collision. The third front-axle link is the track rod which connects the transversely installed steering gear to the wheels. Subframe: robust high-strength-steel construction The front-axle components, steering gear, engine and transmission are pre-mounted on a high-strength-steel subframe which is bolted securely to the bodyshell’s side members, making it a key component in the front crash structure of the new Coupé: in the event of a frontal impact, the subframe forms a separate load-bearing path along which the impact energy is absorbed at specific points. The stiffness at the connecting points between the subframe and the body where load is transferred as a result of the forces and vibrations produced by the chassis and suspension has been increased substantially, all of which translates into more agile and more precise handling. Steering: more direct for agile handlingThe Mercedes Coupé’s AGILITY CONTROL suspension is complemented by a likewise newly developed rack-and-pinion steering system. This operates with a ratio of 14.5, and is therefore around seven per cent more direct than on the outgoing model. Positioning the steering gear 80 millimetres in front of the wheel centre makes for predictable self-steering characteristics with a slight tendency to understeer.  To greatly enhance occupant safety, the steering column has been designed to collapse telescopically by up to 100 millimetres when hit by the driver with a certain degree of force in the event of a frontal collision. This extended deformation path reduces the forces exerted on the driver’s head and chest area. Rear axle: further developed multi-link independent suspension Mercedes-Benz’s multi-link independent suspension, which has proven itself time and again over a period spanning more than 25 years, has been further modified for use in the new E-Class Coupé in order to meet more stringent requirements in terms of comfort and agility. Modified components include the subframe, subframe carrier, struts and hub carriers/steering knuckles. In keeping with the lightweight design concept, wheel location components such as struts, hub carriers and the metal sections of the elastomer bearings are largely made of aluminium. The rear-axle subframe is made of high-strength steel. Optional equipment: sports suspension and dynamic handling packageAlongside the standard-fit AGILITY CONTROL suspension with adaptive damping system, the new E-Class Coupé offers two further options for adapting the suspension to the driver’s individual requirements. One of these optional extras is the AGILITY CONTROL sports suspension with sports-tuned speed-sensitive power steering, stiffer springs, tauter shock absorbers and stronger torsion bars. When cornering or performing evasive manoeuvres at speed, this sporty suspension tuning translates into noticeably lower body roll. The system adjusts the damping force for each wheel individually and fully automatically, depending on the current road conditions and driving situation. When driving normally on poor road surfaces, a soft damper setting is selected to give the occupants maximum comfort while maintaining excellent handling stability and safety. If the driver decides that more brisk progress is called for, however, the shock absorber settings are continuously adapted to meet the need for more dynamic performance. Body Index: outstanding agility without compromising on ride comfortIn order to allow comparison of the suspension characteristics, Mercedes engineers have developed the "Body Index" concept - a composite formula for handling dynamics, 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. In other words, how taut the suspension settings are. The higher the figure, the sportier, i.e. firmer, the suspension characteristics.  The Body Index for the E-Class Coupé with AGILITY CONTROL suspension fitted as standard is 2.0; this figure is around ten percent higher than that for the out-going model and, thanks to adaptive shock absorber control, is achieved without compromising on ride comfort. If the Coupé is equipped with the dynamic handling package, the Body Index is between 1.89 (Comfort) and 2.06 (Sport). Brakes: with Hill-Start Assist, Hold function and brake drying functionWith the ADAPTIVE BRAKE, the E-Class Coupé offers an innovative braking system incorporating additional assistance functions for enhanced comfort and safety. One example of this is the practical HOLD function: after the two-door model has been braked to a standstill, briefly pressing the brake pedal a little further is all that is required to activate this function. The car is then held by the brakes, even if the driver’s foot comes off the brake pedal. In this way, the ADAPTIVE BRAKE prevents the car from rolling forwards inadvertently when stopped at traffic lights or stuck in stop-and-go traffic and from rolling backwards when facing up a slope. The HOLD function is deactivated automatically when the car moves off. The ADAPTIVE BRAKE enhances safety in the wet by sending brief braking pulses at regular intervals to remove the film of moisture from the brake discs, allowing the brakes to work to full effect. This automatic brake drying function is always activated when the windscreen wipers have been operating for a certain time; the driver never even notices these precisely metered brake pulses. Finally, the ADAPTIVE BRAKE assists the driver with hill starts. If the sensors detect that the car is stopped on an uphill slope, a hill-start-assist function is activated automatically, maintaining a constant brake pressure for a brief period to prevent the car from rolling backwards. The driver therefore has enough time to move their foot from the brake pedal to the accelerator without having to use the foot-operated parking brake. Brake discs: larger and even more effective than beforeLarge front and rear brake discs provide an ideal technical basis for ensuring safe and reliable deceleration in any driving situation. The front and rear discs measure up to 344 millimetres and 300 millimetres in diameter respectively, depending on the engine version. Control systems: electronics for safe motoringWhen it comes to active safety systems too, the E-Class Coupé features an array of state-of-the-art technology as standard, including anti-lock brakes, acceleration skid control, Brake Assist and the Electronic Stability Program. For ESP®, Mercedes-Benz has developed control logic that offers the driver even more effective assistance in critical cornering situations: precisely measured brake pulses sent to up to three wheels cause a moderate reduction in the car’s speed and help it to turn safely into bends.  ESP® Trailer Stabilisation, which is activated if the Coupé is equipped with a trailer coupling, detects dangerous oscillating movements of the trailer and restabilises it automatically by sending precisely measured brake pulses to the front wheels of the towing vehicle. If the danger is even more acute, the system applies the brakes to reduce the car’s speed automatically whilst reducing the engine torque before the precisely measured brake pulses are sent to the wheels to stabilise the trailer. Wheels and tyres: 16-inch wheels as standardThe range of wheels and tyres for the new E-Class Coupé offers a wealth of personalisation options. Mercedes customers have a choice of wheel and tyre combinations in 17- or 18-inch format. The four-cylinder models are equipped with 16-inch nine-spoke light-alloy wheels and 215/55 R 16 tyres as standard. As a no-cost option, Mercedes-Benz can also supply 205/55 R 16 tyres with extremely low rolling resistance and special light-alloy wheels whose weight has been reduced by a total of 9.6 kilograms thanks to sophisticated forging technology. &nbs |
