Audi R18 TDI
The R 18 TDI marked the beginning of a new era for Audi in 2011 – it was the brand’s first closed-top sports prototype. Its TDI engine produced approximately 400 kW (over 540 hp) of power and more than 900 Nm (663.80 lb ft) of torque from just a 3.7 liter capacity. The R 18 TDI achieved a narrow victory in a dramatic Le Mans race. Its successor, the R 18 TDI e tron quattro, combining the V6 TDI with a motor-transmission unit on the front axle, became the first hybrid car to win Le Mans, triumphing in both 2012 and 2013.
