Automobili Lamborghini S.p.A.is a brand and manufacturer of luxury sports cars and SUVs based in Sant'Agata Bolognese, Italy. The company is owned by the Volkswagen Group through its subsidiary Audi.
The GTR utilized the same basic 6.0 liter V12 engine that had made its debut on the street-legal GT, but with revised fuel and ignition systems, individual throttle bodies, a dynamic air intake duct system, variable valve timing, titanium connecting rods, and a lightened crankshaft. These improvements allowed the engine to produce 598 PS (440 kW; 590 hp) and 640 N·m (472 lb·ft) of torque.
The engine was bolted to the usual 5-speed transmission in a rear-wheel drive layout. Extra heat exhangers were added for the differential and transmission oil to prevent overheating under extreme racing conditions. A fast-filling racing fuel cell replaced the standard gasoline tank. The suspension was stiffened and lowered, and racing brake calipers were installed.
