The E-Class Estate with its new-generation 4-cylinder engines is particularly efficient. The development theme – higher performance and lower consumption – has been continued undeterred and, thanks to the BlueEFFICIENCY concept, it has been possible to reduce fuel consumption by more than 20 per cent compared with the previous models.

With the exhaust-gas turbocharger, it was possible to increase the efficiency of the 4-cylinder petrol engines considerably. As a result, the optimised 1.8 litre Otto-cycle engines with direct petrol injection and variable valve timing burn fuel particularly efficiently and, thanks to factors including homogeneous direct injection and increased compression, boast a higher output potential than the previous models. They comply with the increasingly stringent EU 5 limit levels in terms of consumption and emissions, while continuing to produce peak torque, power output, low noise levels and, thanks to two balancer shafts, smooth operation. The E 200 CGI BlueEFFICIENCY[1] for instance, delivers 135 kW (184 hp) and develops a maximum torque of 270 Nm, while the E 250 CGI BlueEFFICIENCY[1] has a rated output of 150 kW (204 hp) and a maximum torque of 310 Nm.


(E 200 CGI BlueEFFICIENCY[1]: fuel consumption combined: 7.7–8.1 l/100 km, CO2 emissions combined: 179–189 g/km; E 250 CGI BlueEFFICIENCY[1]: fuel consumption combined: 8.8–8.2 l/100 km, CO2 emissions combined: 185–191 g/km)[2], [3]

The 3.5-litre V6 engine which powers the E 350 CGI BlueEFFICIENCY[4] complies with the EU5 exhaust gas emissions standard. The features of this engine include direct injection and 4-valve technology. The energy efficiency of the auxiliary units has been improved. The new radiator blind optimises the vehicle’s aerodynamics, and the fuel pump, ECO power steering pump and air-conditioning compressor operate in line with requirements.

The rated torque of the E 350 CGI BlueEFFICIENCY is 365 Nm and the engine output is 215 kW (292 hp). This engine combines smooth operation and efficiency with the highest level of agility and handling dynamism. The 6-cylinder engine accelerates from 0 to 100 km/h in 7.0 seconds.[2]

The E 350 4MATIC is available in an all-wheel variant[5]. This engine is equipped with port injection and 4MATIC permanent all-wheel drive, delivers 200 kW (272 hp) and achieves a maximum torque of 350 Nm at 2400 to 5000 rpm.
