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.

The BlueEFFICIENCY measures are comprehensive vehicle optimisations which help save fuel and ease the burden on the environment. The new M-Class also combines the most efficient engines with the optimum aerodynamics and energy management features available to keep fuel consumption to a minimum.

These include:

The newest-generation diesel engines have won much acclaim thanks to their outstanding performance together with their low consumption. Injection pressure has been increased, operating smoothness enhanced and noise levels optimised, while reduced compression makes for lower emissions. Thanks to the systematic deployment of extensive BlueEFFICIENCY technologies, the ML 250 BlueTEC 4MATIC is seen as the paragon of its vehicle class with regard to emissions and fuel consumption.

The new petrol engine’s direct injection and increased compression give outstanding ratings for torque, output and noise reduction. Through the use of innovative engine technology it has been possible to reduce emissions and fuel consumption significantly in comparison to its predecessor.

In addition the 7G-TRONIC PLUS automatic transmission provides optimum fuel consumption by permanently adjusting the engine speed.

(ML 250 BlueTEC 4MATIC: fuel consumption combined: petrol: 6.5–6.0 l/100 km, CO2 emissions combined: 170–158; ML 350 BlueTEC 4MATIC: fuel consumption combined: petrol: 7.4–6.8 l/100 km, CO2 emissions combined: 194–179)[1]
