As the first of our vehicles to receive the new 4.6 liter bi-turbo V8 engine with direct injection, the 2011 CL550 4MATIC Coupe is also the first non-hybrid, non-diesel to receive the BlueEFFICIENCY badge.

BlueEFFICIENCY is the guiding principle for the environmentally responsible development of passenger and commercial vehicles offered under the brands of Daimler AG. BlueEFFICIENCY is not one type of engine or technology but rather a comprehensive approach to improving efficiency while reducing environmental impact.

The new 4.6 liter bi-turbo V8 offers a reduction in fuel consumption and carbon emissions while providing increased horsepower and torque. It is the best of both worlds! Going forward, all of our direct injected vehicles will get the BlueEFFICIENCY badge.
