BlueEFFICIENCY from Mercedes-Benz stands for pioneering efficiency technology as well as innovative packages of measures based on optimising fuel consumption and emission levels.
BlueEFFICIENCY measures are comprehensive vehicle optimisations that help to save fuel and ease the burden on the environment. In the SLK, too, the most efficient engines are combined with the best matching aerodynamics and energy management measures, to keep fuel consumption to a minimum.
Direct injection, downsizing, increased compression and turbocharging in the new engine generation enable top torque, output and noise reduction figures. Innovative engine technology makes it possible to reduce emissions and fuel consumption significantly 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.
 Available for the SLK 250 CDI BlueEFFICIENCY and SLK 200 BlueEFFICIENCY
