Drive system and suspension: Sporty and comfortable driving pleasure

Mar 10, 2017

Powerful and efficient petrol and diesel engines, all equipped with ECO start/stop and complying with the Euro 6 emissions standard, provide for lively performance and great fun behind the wheel. The available variants include a newly developed four-cylinder diesel engine.

On market launch of the E-Class Coupé there will initially be one diesel and three petrol engines available. Further engine variants and 4MATIC versions will follow.

New four-cylinder diesel engine

Designed to meet the future RDE limits, the four-cylinder diesel engine from the new family of Mercedes-Benz engines opens up a new dimension in efficiency. With a displacement of around two litres, the new diesel engine delivers 143 kW/194 hp, while the E 220 d impresses with a combined NEDC average consumption of 4.0 litres per 100 kilometres. This is equivalent to CO2 emissions of 106 grams per kilometre. In addition, the four-cylinder with single-stage turbocharger and variable turbine geometry is distinguished by a high level of refinement. Both the cylinder head and the crankcase are made of aluminium. The Mercedes-Benz-developed NANOSLIDE® surface coating efficiently reduces the friction between cylinder liner and steel piston.

Nine-speed automatic transmission

All models available at market launch are equipped as standard with the new 9G‑TRONIC nine-speed automatic transmission. It ensures fast gear changes and allows low engine revs. This has a particularly beneficial effect on efficiency and noise. From mid-2017, the range will be extended by the E 200 with a 6-speed manual transmission.

Suspension – sporty comfort

The suspension on the new E-Class Coupé offers agile driving pleasure on winding roads together with exceptional ride comfort. The Coupé comes as standard with AGILITY CONTROL suspension. In the interests of a sporty look, the suspension is 15 millimetres lower than on the Saloon and is tuned for comfort with an amplitude-dependent damping system.

The DYNAMIC BODY CONTROL suspension with adjustable damping is optionally available. It, too, is set lower. Using a switch in the centre console for the standard DYNAMIC SELECT system, the driver can vary the damping characteristics of this suspension. Three modes are available, offering a wide range of adjustment options: "Comfort", "Sport" and "Sport+".

AIR BODY CONTROL multi-chamber air suspension

Alternatively, the new E-Class Coupé can be equipped with multi-chamber air suspension, including all-round roll/pitch/heave stabilisation. Advantages of this system: three chambers of different size in the spring struts of the rear axle and two in the spring struts of the front axle make it possible to control the hardness of the suspension in three stages. In this way, the occupants enjoy soft basic suspension, along with the secure feeling of good handling stability at higher speeds.

Furthermore, the highly sensitive and fast-responding AIR BODY CONTROL multi-chamber air suspension features all-round self-levelling for excellent ride comfort even with the vehicle loaded. It controls the ride height automatically depending on the speed and reduces fuel consumption on the motorway, for example, by lowering the vehicle. When driving on rough roads or access roads, the ground clearance can also be increased at the push of a button using the ride height adjustment switch.

The multi-chamber air suspension is augmented by a continuous, electronically controlled adaptive damping system. The damping at each individual wheel is adjusted fully automatically to suit the current driving situation and condition of the road – such as in the case of evasive manoeuvres or on rough tracks. The system therefore delivers good ride comfort along with excellent driving dynamics.

Using the DYNAMIC SELECT switch, the driver can also select different suspension characteristics in combination with the AIR BODY CONTROL system: "Comfort", ECO, "Sport", "Sport +" and Individual.

DYNAMIC SELECT – choose your own driving characteristics

However, the DYNAMIC SELECT system not only makes it possible to select the suspension characteristics in combination with DYNAMIC BODY CONTROL and AIR BODY CONTROL, it also enables the driver to influence other vehicle settings – such as the throttle response, ECO start/stop function, shift points of the automatic transmission and more. Depending on the equipment level, DYNAMIC SELECT provides the following transmission modes: Comfort, ECO, Sport, Sport + and Individual. "Individual" allows drivers to configure their own preferred vehicle settings.

Independent multilink suspension at front and rear

The agile handling is due in large part to the 4-link front axle, which releases the spring strut from wheel control duties. In addition, the four-link principle offers favourable axle kinematics. For example, it allows an improved camber change for higher cornering forces. As a result, the suspension responds more sensitively to steering movements and allows a sporty, agile driving style. As components of the new front axle are made of aluminium, they weigh about two kilograms less than a corresponding steel design. This reduction in weight supports a sensitive response and contributes to the efficiency of the new E-Class Coupé.

An optimised multi-link independent rear suspension with 5 links ensures excellent wheel control qualities and supreme straight-line stability. The rear axle carrier and the spring control arms are made of forged aluminium. A large rear axle bearing contributes to improved isolation of vibrations and thus to the good NVH characteristics and ride quality.

Sporty steering feel

All models of the E-Class family are equipped as standard with a sporty, electromechanical Direct-Steer system. It combines speed-sensitive power assistance for the speed-sensitive steering with a steering ratio that varies according to the given steering angle. The power assistance for the rack-and-pinion steering gear is controlled on demand.

STEER CONTROL – steering assistance in critical situations

The E-Class Coupé is equipped with the STEER CONTROL steering assistance function as standard. It can help the driver to stabilise the vehicle in difficult handling situations. To this end, the electronics determine in which direction the driver has to steer to defuse a critical situation, and introduces a corresponding electric steering torque into the steering that the driver clearly perceives. In this way STEER CONTROL provides the driver with prompts in which direction to steer in order to stabilise the vehicle. If the vehicle oversteers, the steering wheel provides the driver with the prompt for correct countersteering until the vehicle is safely back on course.

Fade-resistant brakes for short stopping distances

The ADAPTIVE BRAKE braking system with internally ventilated compound brake discs meets high standards in terms of stopping distance, response, fade resistance, directional stability and service life of the brake pads. Single or 4-piston sliding callipers on the front and rear axles with brake discs the size of which depend on the engine provide for rapid deceleration.
