After launching the V10-powered R8 Audi is working on a Clubsport version, which was spotted doing a few laps around the track at the Nürburgring in Germany.
Though there is no official indication of such a derivative for the R8 range, the large, fixed rear wing and some other body tweaks hint at an even racier R8. Also the diffusor down between the pipes has grown a little bit.
Rumours have that such a model will be about 50kg lighter and be rear-wheel drive with a bit more power.
It could be presented on the Essen Motor Show in late November 2009 and be on sale in the first quarter of 2010.
