At the same time that the DTM competes at Hockenheim the customer sport program of AUDI AG that was launched with the Audi R8 LMS will probably feature an additional vehicle: at the last two rounds of the Endurance Championship Nürburgring on October 16 and 30, Team Raeder Motorsport will contest the SP 4T class with the prototype of an Audi TT RS that is jointly developed by the Technical Development (TE) and Production divisions of AUDI AG and quattro GmbH. In the test races the vehicle, which spearheads a potential modular customer sport concept based on the TT, will be driven by Marc Hennerici and Christopher Mies. Audi thereby responds to the high demand by customers wishing to use the TT and other vehicles of the brand in motorsport.

 
The prototype uses a five-cylinder TFSI engine and features racing-specific new developments in the areas of the body, suspension and aerodynamics. In addition, the team was able to adopt some components from the R8 LMS in order to make maximum use of synergies.
