The new E-Class Coupé offers a very special combination of two attributes for which the Mercedes brand is known: fascination and efficiency. With its classic coupé side aspect – no B-pillars and fully retractable side windows – the new two-door car is a particularly sporty interpretation of the E-Class’s dynamic design. At the same time the most aerodynamic variant of the Coupés achieves a new world best in terms of drag coefficient: with a Cd‑figure of just 0.24, this model is the world’s most aerodynamically efficient series-production car. The model programme includes two new 4‑cylinder engines, which consume up to 17% less fuel whilst offering a significant increase in performance and torque. The new E-Class Coupé’s standard-fit AGILITY CONTROL suspension adjusts automatically to the current driving situation. It combines driving enjoyment and excellent handling with the maximum comfort.
The new Coupé offers all the technical innovations of the new E-Class series that one might expect to find in a sports-oriented luxury coupé. These include selective damper control, drowsiness detection, preventive occupant protection and the Active Bonnet. As a feature specific to the Coupé, the Dynamic Driving package allows different suspension setups at the touch of a button. Adaptive Main Beam Assist, road sign recognition and an automatic emergency braking system are other features with which the new series sets standards in this vehicle category.
The E-Class also takes on a pioneering role in the drive sector. The new diesels and direct-injection petrol engines combine efficiency with an effortless power delivery. The engine line-up includes two new four-cylinder models which deliver significantly more power and torque while consuming up to 17 percent less fuel. The best example is the E 250 CDI BlueEFFICIENCY Coupé, which consumes 5.1 l/100 km (46.12 mpg/US, 19.60 km/l) diesel and emits 135 grams of CO2 per kilometre, making it one of the most economical vehicles in its class.
The exemplary, low fuel consumption has not only been achieved because of the new engines, but also with a number of practical measures. These include on-demand activation of the steering and fuel pumps, the use of tyres with low rolling resistance and an alternator control system which takes account of the current driving situation and the vehicle’s electrical power requirements, plus the very decisive factor of outstanding aerodynamics .
The design of the new two-door model includes traditional styling elements which give Mercedes-Benz Coupés their unmistakable identity: for example the side windows, which are not interrupted by a B-pillar and are fully retractable. Another hallmark of Mercedes Coupé design is the sports radiator grille with the large central star. At the same time, however, the new model points the way to the future with an exciting, contemporary design idiom.
At the same time the Coupé shows its close family resemblance to the E-Class Saloon. This is shown by the ‘twin-headlamp face’, with rhomboid contours but somewhat sportier, sharper treatment for a more dynamic and incisive look.
Although it shares family traits with the Saloon, the Coupé has its own, distinct identity characterised by effortless superiority and a greater sense of passion. The arrow shape of the entire front section from front bumper to radiator to bonnet, the more extreme interpretation of the twin headlamp face and its more sinewy build give it a racier and more dynamic presence.
The seats of the E-Class Coupé are new developments whose design and techno-logy reflect the sporty nature of this two-door Mercedes. They are electrically adjustable for seat height and backrest angle as standard. The high, sports car-like seat backrests have a practical Easy-Entry function to make access and egress easier for rear-seat passengers. In conjunction with electric seat adjustment with memory (an optional extra), the front seats are equipped with electropneumatically adjustable four-way lumbar supports; these are able to provide anatomically favourable support for the lower spine, which further improves seating comfort.
Luxury seats with leather upholstery and active ventilation are available as optional extras, as are newly developed multicontour seats with inflatable air chambers in the front seat cushions as well as in the centre and side bolsters of the backrests. Two comfortable individual seats are available for the rear passengers. These feature backrests which can be folded down individually or together to increase the capacity of the luggage compartment.
Engines: fuel consumption down by 17 percent
The diesel in the E 250 CDI BlueEFFICIENCY Coupé is the top-of-the-range unit in the new generation of Mercedes-Benz four-cylinder engines, which are notable for features such as two-stage turbocharging, precise piezo injectors and the latest common-rail technology. The engine has an output of 150 kW/204 hp and develops a maximum torque of 500 Nm (368 lb-ft) which is available from just 1600 rpm. This means that it is some 36 percent more powerful than the four-cylinder diesel in the preceding model yet consumes 17 percent less fuel: 5.1 l/100 km (46.12 mpg/US, 19.60 km/l) NEDC (New European Driving Cycle). This corresponds to a carbon dioxide emission level of 135 gramsper kilometre.
The turbocharged V6 diesel engine with common-rail direct injection remains in the line-up. Fitted in the E 350 CDI BlueEFFICIENCY Coupé, it develops 170 kW/231 hp (previously: 165 kW/224 hp) and consumes 6.8 l/100 km (34.59 mpg/US, 14.70 km/l) (combined) in the NEDC cycle. Its carbon-dioxide emissions are 179 grams per kilometre.
Two new petrol engines with direct injection
Mercedes-Benz has also chosen to move over to direct-injection technology for its petrol engines. Once again, the E-Class Coupé points the way: the powerplant at work under the bonnet of the E 250 CGI BlueEFFICIENCY Coupé is a newly developed four-cylinder direct-injection unit with 150 kW/204 hp and a five-speed automatic transmission as standard. This engine makes do with 7.2 l/100 km (32.66 mpg/US, 13.88 km/l) combined NEDC. CO2 emissions are 167 grams per kilometre. This is some 13 percent less than the figure for the previous four-cylinder engine (135 kW/184 hp) with conventional fuel injection.
Mercedes-Benz has replaced the previous V6 petrol engine with the world’s first six-cylinder unit featuring spray-guided direct petrol injection in the new E 350 CGI BlueEFFICIENCY Coupé. This engine develops 215 kW/292 hp – an extra 15 kW/20 hp – and consumes about 14 percent less fuel than the previous V6 engine: its combined NEDC consumption is just 8.5 l/100 km (27.67 mpg/US, 11.76 km/l). This corresponds to 199 grams of CO2per kilometre.
In the top-of-the-range model, the E 500 Coupé, the muscular V8 engine with 285 kW/388 hp and 530 Nm (391 lb-ft) of torque offers the performance characteristics of a sports car. Mercedes engineers have enhanced details of the eight-cylinder unit, reducing the fuel consumption (compared to the preceding model) by 0.5 litres to 10.9 l/100 km (21.57 mpg/US, 9.17 km/l) NEDC. All the engines in the new E-Class Coupés meet the EU5 exhaust emission standard.
