BlueEFFICIENCY from Mercedes-Benz stands for pioneering efficiency technologies as well as innovative packages of measures based on optimising 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 E-Class Cabriolet also features the most efficient engines, combined with optimum aerodynamics and energy management measures, to keep fuel consumption to a minimum.

The current generation of CDI diesel engines display compelling performance characteristics coupled with low consumption levels. Injection pressure has been increased to up to 2000 bar, smoothness of operation enhanced and noise levels optimised, while reduced compression makes for lower emission levels.

Direct injection, increased compression and turbocharging in the new petrol engines generate outstanding torque, output and noise reduction figures. Innovative engine technology has significantly reduced emissions and fuel consumption compared with previous models.
