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 ECO start/stop function reduces fuel consumption and emissions by switching off the engine automatically when the car comes to a stop (e.g. in traffic jams or at traffic lights). If a vehicle is equipped with the ECO start/stop function, a starter/generator is installed in place of the starter. Intelligent control electronics allow the starter/generator to supply the electrical energy for the vehicle's electrical system and, in starter mode, the torque required to start the engine.
Significant savings can also come from a series of small contributions. With the aim of making the E-Class Cabriolet more fuel efficient, the Mercedes-Benz engineers examined all the main components with regard to their energy usage and found ways of getting them to work more economically. Overview of efficient energy management measures:
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.
