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 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 new Coupé offers all the technical innovations of the new E-Class series that one might expect to find in a sports-oriented luxury coupé. These include selective damper control, drowsiness detection, preventive occupant protection and the Active Bonnet. As a feature specific to the Coupé, the Dynamic Driving package allows different suspension setups at the touch of a button.
The seats of the 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.
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.
Mercedes-Benz has also chosen to move over to direct-injection technology for its petrol engines. 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 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.
The well-proven operating concept from the S-Class, comprising the multifunction steering wheel, Controller on the centre tunnel, colour display in the dash-board and direct selection buttons also offers the occupants of the new E-Class Coupé a 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 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.
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.
Deliveries of the E-Class Coupé will start in June 2009 and pricing is soon to be confirmed.
