Audi has teamed up with Raeder Motorsport to produce this extreme-looking TT RS endurance racer.
The car is already undergoing testing and will compete in the SP 4T class of the Endurance Championship Nürburgring in the races on 16 and 30 October when it will be raced by Marc Hennerici and Christopher Mies.
The engine it uses has not yet been confirmed. The standard car uses a 2.5-litre, turbocharged 5-cylinder TFSI engine. Improvements to the car's chassis and aerodynamics have been made using components from the Audi R8 LMS that competes in the Le Mans Series.
The TT model was used by privateer squad Abt Sportsline when it competed in the DTM championship between 2000 and 2003.
