The drive system of the E 220 BlueTEC BlueEFFICIENCY Edition uses the Mercedes-Benz four-cylinder diesel engine with direct injection. It is extremely fuel-efficient, but still manages to generate 125 kW (170 hp) with an engine displacement of 2143 cubic centimetres.
 
It also provides staggering torque of 400 Nm. Among other things, these qualities can be attributed to the high-tech compression-ignition engine’s fourth-generation common-rail technology. The special model’s drive package also features a 7G-TRONIC PLUS automatic transmission that has been optimised with respect to driving comfort and consumption, as well as an ECO start/stop function.

Other fine tuning includes low-resistance tyres on 16 or 17-inch wheels, the lowering of the chassis by up to 15 millimetres and a radiator blind that directs the flow of air as required and thus improves aerodynamics. The upshot of these measures: 4.4 litres of diesel per 100 kilometres (NEDC combined). That corresponds to CO2 emissions of 114 grams per kilometre, beating all other cars in its segment. As a result, the new special model of the Mercedes-Benz E?Class (which already meets the future Euro 6 emissions standard) has been assigned to the best efficiency class (A+).

The E 220 BlueTEC BlueEFFICIENCY Edition proves that ecology and temperament can go hand-in-hand, accelerating from 0 to 100 km/h in 8.4 seconds and reaching a top speed of 227 km/h.

The new special model is available in all of the equipment lines provided for the E-Class, and can also be combined with any equipment package.
