The 2011 version of the world's most successful GT racer from Weissach has received some extensive modifications as it begins the new racing season. The 4.0-liter six-cylinder boxer engine now boats 455 hp at 7,800 revs, which is five hp more than its predecessor. The power increase comes from the engine management system that now adapts better to different fuel grades and a redesigned exhaust system and a modified air intake housing.
Exterior mods include a new front lip that provides higher downforce from the front axle and the front wheels are now wider with rims an extra inch longer to provide additional grip and less understeer. Both the position and shape of the rear wing were also optimized. The rear lid was redesigned for improved air ducting. The 2011 RSR also now comes equipped with LED rear lights that come directly from the latest 911 street legal cars and racing teams can order it for a price of €410,000.
