I don't know yet. But they showed me the Audi TT (ex DTM race car). This race car is being displayed all over Europe. The purpose is, I believe, like you said a "virtual racing" but I don't think a 24h virtual race. It's a simulator everybody can try, I think.
All will be clear june 17 and 18 at the Nürnburgring.
I know it's stupid but I'm a little proud that my (ex) pedals will be travalling around Europe in a real race simulator.
