With the upcoming American Le Mans Series also providing a stage for the US market, Audi announced plans in 1998 to compete in 1999, with the Audi R8R powered by a V8 turbo. As it was considered the better choice for a whole race due to less weight and wider tires, Audi ordered an open-top roadster from Dallara, to be developed and run by Joest Racing.
