The Audi R18 is a Le Mans Prototype (LMP) racing car constructed by the German car manufacturer Audi AG. It is the successor to the Audi R15 TDI. Like its predecessor, the R18 uses a TDI turbocharged diesel engine but with a reduced capacity of 3.7 litres and in a V6 configuration. For the first time since the 1999 R8C, Audi's Le Mans prototype uses a closed cockpit design. The R18 is also the first racing car from Audi to feature hybrid power.
