R-GT was developed in cooperation with Audi Sport and motorsports experts Reiter Engineering. Built to the requirements for FIA and ACO, this Murcielago was converted from all-wheel drive to rear-wheel drive, with a sequential gearbox. Total weight will be under 2425 lbs. to satisfy regulations. Power will come from a 6.0-liter V-12, though specific output was not released. Priced over $500,000, the production Murcielago R-GT will be ready for events like the FIA GT Championship and American Le Mans Series.
