The E-Class 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 already today comply with the increasingly stringent EU 5 limit levels in terms of consumption and emissions, in spite of which they continue to produce peak torque, power output, low noise levels and, thanks to two balancer shafts, smooth operation. The E 200 CGI BlueEFFICIENCY for instance, delivers 135 kW (184 hp) and develops a maximum torque of 270 Nm, while the E 250 CGI BlueEFFICIENCY has a rated output of 150 kW (204 hp) and a maximum torque of 310 Nm.


(E 200 CGI BlueEFFICIENCY: fuel consumption combined: 7.2–7.9 l/100 km, CO2 emissions combined: 169–184 g/km; E 250 CGI BlueEFFICIENCY: fuel consumption combined: 7.6–8.0 l/100 km, CO2 emissions combined: 179–187 g/km)[2]

Concentrated power is packed into the 8-cylinder engine of the E 500. It complies with EU 5 emissions standard and deliver a powerful 285 kW (388 hp) at a maximum torque of 530 Nm. The E 500 accelerates within 5.2 seconds from 0 to 100 km/h.

The E 63 AMG boasts the most powerful engine. It is a thoroughbred sports engine, which delivers outstanding performance thanks to its high-speed concept and naturally aspirated engine design. It accelerates the E-Class from 0 to 100 km/h in just 4.5 seconds – that says just about everything.

(E 500: fuel consumption combined: 10.8–11.2 l/100 km, CO2 emissions combined: 253–261 g/km; E 63 AMG: fuel consumption combined: 12.6 l/100 km, CO2 emissions combined: 295 g/km)[2]
