BlueEFFICIENCY from Mercedes-Benz stands for pioneering efficiency technologies as well as innovative packages of measures for the optimisation of fuel consumption and emission levels.
Two BlueEFFICIENCY models available for the S-Class, equipped with environmentally friendly technologies and extensive special measures.
The environmentally compatible HYBRID drive technology combines the power of an efficient petrol engine with the strengths of an electric motor. A powerful and weight-reduced lithium-ion battery supplies the high-torque electric motor. In combustion mode, the electric motor operates as a generator and feeds energy back into the system. At the same time, brake energy recharges the lithium-ion battery using the regenerative braking system when the brakes are applied. The boost function allows the power of both engines to be used for a brief period when accelerating.
The latest-generation CDI diesel engines display compelling performance characteristics coupled with low consumption levels. Injection pressure has been increased, smoothness of operation enhanced and noise levels optimised, while reduced compression makes for lower emission levels.
Depending on the engine installed, the BlueEFFICIENCY models are equipped with a series of different measures. These are for instance:
