BlueEFFICIENCY from Mercedes-Benz stands for pioneering efficiency technologies as well as innovative packages of measures based on optimising fuel consumption and emission levels.

BlueEFFICIENCY measures are comprehensive vehicle optimisations that can help to save fuel and ease the burden on the environment. In the new E-Class Cabriolet, too, the most efficient engines are matched with the optimum aerodynamics and energy management measures to keep fuel consumption to a minimum.

The current generation of CDI diesel engines combine irresistible performance characteristics with low consumption. Injection pressure has been increased to up to 2000 bar, operation smoothness enhanced and noise levels optimised, while reduced compression makes for lower emissions.<br/><br/>In the new petrol engines, direct injection, increased compression and – in many cases – turbocharging generate outstanding torque, output and noise reduction figures.
Innovative engine technology has significantly reduced emissions and fuel consumption compared with earlier models.<br />
