​

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 car manufacturer Audi AG in 2006. The car is exclusively designed, developed, and manufactured by Audi AG's private subsidiary company manufacturing high performance automotive parts, It is based on the Lamborghini Gallardo and the fundamental construction of the R8 is based on the Audi Space Frame,[2] and uses an aluminium monocoque which is built using space frame principles. 

The Audi R8 was initially equipped with a 4.2 litre V8 engine. Specifically, it is an all-aluminium alloy 32-valve (four valves per cylinder) petrol engine, utilising Fuel Stratified Injection (FSI), and has a displacement of 4,163 cubic centimetres. It develops a motive power output of 414 bhp and generates 317 lbf⋅ft of torque, on 98 RON 'Super Unleaded' petrol. It is basically the same engine used in the Audi B7 RS4, but is modified to use a dry sump lubrication system. It uses two chain-driven double overhead camshafts per cylinder bank, and utilises variable valve timing for both inlet and exhaust camshafts. The 4 wheel drive system is biased towards the rear; it sends 30% of its power to the front wheels and 70% to the rear.​
