The Audi R8 is a mid-engine, 2-seater sports car, which uses Audi's trademark quattro permanent all-wheel drive system. It was introduced by the German automaker Audi AG in 2006.
The car was exclusively designed, developed, and manufactured by Audi AG's high performance private subsidiary company, quattro GmbH, and is based on the Lamborghini Gallardo platform. The fundamental construction of the R8 is based on the Audi Space Frame, and uses an aluminum monocoque which is built using space frame principles. The car is built by quattro GmbH in a newly renovated factory at Audi's "aluminum site" at Neckarsulm in Germany.
Audi AG unveiled the Audi R8 V10 on 9 December 2008. It boasts a 5.2 litre FSI engine, based on the unit in the Lamborghini Gallardo LP560-4 (which in turn was based on the 5.2 FSI V10 used in the Audi C6 S6 and Audi D3 S8), but is re-tuned to produce a power output of 532 metric horsepower (391 kW; 525 bhp), and generate 530 newton metres (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 kilometres per hour (0 to 62.1 mph) time as only 3.9 seconds, 60 to 124 miles per hour (97 to 200 km/h) in 8.1 seconds, and a top speed of 316 kilometres per hour (196.4 mph). Other changes to the V10 version of the R8 include some aesthetic differences: such as all-LED headlights (a world-first), interior enhancements such as Bang & Olufsen 465 watt sound system, a more aggressive body styling, larger rear brakes, and unique roadwheels.
