Mercedes-Benz' in-house tuning arm, AMG, has announced the horsepower wars are over, and the automaker is gearing up to implement a new range of technologies that will help reduce fuel consumption by 2012.

According to AutoTelegraaf, M-B will introduce start-stop technology on AMG models as early as next year, along with launching a direct-injection system based of the second-generation currently employed on the C350 CGI BlueEfficiency. The automaker has set an internal goal of reducing fuel consumption across its line-up by 30% in the next three years. While diesels and new engine technologies will go a long way to achieving that goal, Mercedes plans to begin reducing the weight of its vehicles through the use of more composite materials and other weight-saving assembly procedures.
