Mercedes Benz launched the 2012 S350 Bluetec at the 2011 Detroit Auto Show. It's a diesel-powered S-Class destined for consumption only in United States. Audi, BMW and Jaguar don't provide an oil-burning version in U.S. The technical specifications of the 2012 S350 Bluetec has not been revealed but it would be powered by the same 3.5-liter Bluetec V6 found in the E-, ML- and GL-Class vehicles.
