Lamborghini Diablo GTR

The Lamborghini Diablo GTR is a mid-engined GTR race car by Lamborghini. It appears in Asphalt Urban GT.

Overview
For the 2000 Diablo Supertrophy season, Lamborghini launched a completely new car, the Diablo GTR, a race-ready Diablo GT converted into a track car with an improved engine, a stripped interior, and extensive use of weight reduction.

The GTR interior was stripped down to save weight; the air conditioning, stereo, and sound and heatproofing were removed, and a single racing seat with 6-point seatbelt harness, MOMO fire suppression system and steering wheel, complete integrated roll cage, fixed Plexiglass windows with sliding sections, and fresh air intake were fitted. The GT had already featured a radically styled body, but the GTR took this a little further with features such as a very large rear wing bolted directly to the chassis like with actual race cars, 18 inch hollow magnesium Speedline centerlock wheels, pneumatic air jacks for raising the car in the pit lane, and an emergency fuel shutoff switch on the left front fender.

The Diablo GTR's engine is an optimized variant of the 6.0 L (5,992 cc) naturally aspirated V12 that had debuted on the Diablo GT, but with the inclusion of revised fuel and ignition systems, individual throttle bodies, a dynamic air intake duct system, variable valve timing, titanium connecting rods, and a lighter crankshaft. Consequently, the power was increased to and  of torque. The engine was mated to the usual rear-driving 5-speed manual transmission.

30 units were planned, but an additional 10 more were built for a total of 40.
