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 E-Class Estate combines the most efficient engines with optimum aerodynamics and energy management features to keep fuel consumption to a minimum.

The latest-generation CDI diesel engines combine irresistible performance characteristics with low consumption. Injection pressure has been increased, smoothness of operation enhanced and noise levels optimised – while reduced compression makes for lower emission levels.

Direct injection, increased compression and turbocharging (for V8 engines) in petrol engines deliver outstanding torque, output and noise reduction figures. Innovative engine technology has significantly reduced emissions and fuel consumption compared with previous models.

Mercedes-Benz is the world's only automotive brand to have been awarded Environmental Certificates in accordance with ISO standards. Certified vehicle models are subjected to strict statutory requirements and monitoring during development, production and recycling. Our aim is to make environmental protection objectively quantifiable and tangible to you, the driver.
