Audi AG unveiled the Audi R8 V10 on December 8, 2008. It uses a FSI V10 engine, based on the unit in the Lamborghini Gallardo LP560-4 (which in turn was based on the 5.2 FSI V10 as used in the C6 S6 and D3 S8), but is re-tuned to have a power output of 532 PS (391 kW; 525 hp), and 530 N⋅m (391 lbf⋅ft) of torque. Compared to the V8 variant, the R8 V10's performance numbers are enhanced. Audi states the new 0 to 100 km/h (0 to 62 mph) acceleration time as 3.9 seconds, 97 to 200 km/h (60 to 124 mph) in 8.1 seconds, and a top speed of 316 km/h (196 mph). Other changes to the V10 version of the R8 include some aesthetic differences: such as all- LED headlights (a world-first), "V10" badging on the front fenders, interior enhancements such as Bang & Olufsen 465 watt sound system, a more aggressive body styling, larger rear brakes, a dual outlet exhaust system and different wheels.
