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 technology refers to comprehensive vehicle optimisations which save fuel and ease the burden on the environment. The CLS Coupé combines the most efficient engines with thoroughly thought-out aerodynamic features and energy management measures to keep fuel consumption to a minimum.
There are six BlueEFFICIENCY models available for the CLS, equipped with environment-friendly technologies or extensive range of measures.
ECO start/stop function
The ECO start/stop function reduces fuel consumption and vehicle emissions by switching off the engine when the vehicle is at a standstill.
Intelligent energy management
Significant savings can also come from a series of small contributions. With the aim of reducing the fuel consumption of the CLS Coupé, 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:
Efficient alternator management: the kinetic energy from braking and coasting is used to charge the battery.
More efficient fuel management: the pumping pressure of the fuel pump is based on the precise amount of fuel needed at the time.
Air conditioning only as required: if not required, the compressor is automatically decoupled from the engine’s belt drive.
Efficiency technologies in the CLS Coupé
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 an entirely new air intake and exhaust system in the BlueDIRECT V6 and V8 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 only automotive brand in the world to have received an ISO-standard Environmental Certificate. For this certification, the vehicle models have to meet strict requirements and undergo stringent controls in their development, production and recycling. Our goal is to make environmental protection objectively measurable and to make it possible for you as the driver to experience it concretely.
