The new E-Class will come with a choice of two engines at market launch: the E 200 with a four-cylinder petrol engine and the E 220 d with an all-new four-cylinder diesel engine.
Further model variants will be added to the range after the market launch, including the E 350 e featuring hybrid technology. The PLUG-IN HYBRID impresses with its dynamism and efficiency, allowing around 30 kilometres of purely electric and therefore locally emission-free driving. Its four-cylinder petrol engine, in conjunction with a powerful electric motor, gives it a total system output of 210 kW (286 hp) with a system torque of 550 Nm. With this set-up, the E 350 e achieves the performance of a sports car yet consumes less fuel than a small, compact-class car.
The most powerful diesel variant will boast a six-cylinder engine incorporating advanced SCR exhaust technology, with an output of 190 kW (258 hp) and a peak torque of 620 Nm.
Another variant to join the range will be the E 400 4MATIC whose six-cylinder petrol engine has an output of 245 kW (333 hp) and a maximum torque of 480 Nm.

|E 220 d||1950||143/195||400||7.3||3.9||102|
|E 350 d||2987||190/258||620||5.9||5.1||133|

Further variants will later complete the engine range, including a new four-cylinder diesel unit developing 110 kW (150 hp). The range of petrol engines will comprise four-cylinder versions with outputs ranging from 135 to 180 kW (183 to 245 hp) plus a six-cylinder variant developing 245 kW (333 hp).
All engines for the new E-Class are equipped with the ECO start/stop function. The petrol engines meet the requirements of the EU 6 emissions standard, while the new OM 654 four-cylinder diesel engine is already configured with future RDE limits in mind.
All-new four-cylinder diesel engine
The new four-cylinder diesel unit marks the birth of a new Mercedes-Benz engine family and opens up new dimensions in efficiency. What’s more, it is shorter and more compact than its predecessor thanks to reduced cylinder spacing (90 mm instead of 94 mm). Despite having a lower displacement than its predecessor, reduced to around two litres, the new diesel powerplant has an output of 143 kW/195 hp and, when installed in the E 220 d, delivers NEDC combined consumption of just 3.9 litres per 100 kilometres, which equates to CO2 emissions of 102 grams per kilometre – a figure that until now only significantly smaller vehicles have been able to deliver.
In addition to this, the four-cylinder unit is exceptionally refined. In its basic form it features single-stage turbocharging and variable turbine geometry. Both the cylinder head and the crankcase are made of aluminium. The Mercedes-Benz developed NANOSLIDE® surface coating efficiently reduces the friction between cylinder surface and steel piston.
All models available at market launch are equipped with the new 9G-TRONIC nine-speed automatic transmission as standard. It enables fast gear changes and allows low engine revs, which has a particularly beneficial effect on efficiency and noise levels.
