Automotive designer Peter Stevens was directly involved in Audi’s Le Mans project before the R8R LMP1 car when the people over at Ingolstadt were analyzing the prospects of a producing a road-going supercar as well as a racecar for Le Mans. If the cars made it to production, both the road and race versions would have featured a twin-turbo mid-mounted V8 engine mated to a 6-speed sequential gearbox. Also on the agenda were OZ wheels, four-piston Brembo brakes, an aluminum & carbon monocoque chassis and double wishbone inboard coil spring dampers.
The G-TT was supposed to be Audi’s GT2 and during that time Audi was testing a first generation TT equipped with a mid-mounted V8 engine. After the car would have come to fruition, the next project to embark on was an Audi R8 GT1 Le Mans derivative which was tested in ex F1 Brabham Team’s aerodynamic facility.
The Audi R8 GT1 would have been benchmarked against reputable competitors such as the Porsche 911 GT1 as well as the Mercedes-Benz CLK GT1 but times changed and Audi had to adjust to the new situation.
Codenamed “Aurora”, the project was created to form the basis of the Audi GT1 R8 but the Le Mans Prototype (LMP) category was introduced and focus was shifted towards a LMP vehicle. The group led by Richard Lloyd eventually created the Audi R8C for the 24-hour Le Mans endurance race of 1999.
