Built in May 1993 by Audi Sport

In 1994 the car served as a spare for Philippe Adams in Belgian Procar - he would use RT03 as his race car.

During 1995 the car was driven by Vincent Vosse in Belgian Procar, except for the July Spa-Francorchamps meeting where he would drive the spare car (RT03) and the August Spa Francorchamps where he would drive Philippe Adams' later car (RT13)

Driven in 1997 by Jiří Zbožínek in the FIA Central European Supertouring Championship as well in a number of European Hillclimb events. During 1997 it was also rented by Niko Pulić for use in the Croatian Touring Car Championship

Sold in 1998 to Michael Endress who drove it in European Hillclimb events.

In early 2000, the car was sold to Sweden and later to Norway minus it's engine and gearbox. Since then the car has been heavily modified and fitted with a turbo engine.

In 2019 the car was purchased by Paal André Fylling, who began restoring it to original STW specification.
