The Murcielago R-GT is a race-only version of the Murciélago, developed jointly with renowned race car engineering company Reiter Engineering in Germany, and parent company Audi's sports division Audi Sport, will offer Lamborghini clients a car with which to compete in global professional motor sport... The car retains the standard Murciélago V12, but has air restrictors to manage power. Its acceleration and top speed are highly dependent on the gearing selected for a particular race track.
In March 2006 at the Super GT Suzuka, a Murcielago R-GT specifically built for Super GT (and rebadged RG-1) for the Japanese Lamborghini Owners Club (JLOC) recorded the first win ever for a Murcielago when they earned a win in the GT300 class. In March 25th 2007 in the FIA GT Championship, the All-Inkl.com Racing Murciélago won the Zhuhai 2 Hours.
