Audi R10 TDI (2006)

Power and efficiency: The Audi R10 TDI was the first racing car with TDI engine – and an extremely successful one at that. Its V12 delivered around 480 kW (over 650 hp) and more than 1,100 Nm (811.32 lb-ft) of torque, good for a top speed of over 330 km/h (205 mph). The sports prototype was also impressive for its efficiency and durability. By the end of its three-year career, the
R10 TDI had notched up 22 overall wins in 38 races.
