Audi->ke14 is already offering the public the R8 GT packed with 560 HP, but we know the company can do better than that and, today, they proved it! Spy shots have revealed that an even more powerful R8 is already testing. It is rumored to be called the RS and will deliver 600 HP.

The car caught testing features motorsport-style stripes, an new front splitter and side skirts that sit dramatically close to the ground, a plastic engine cover, and huge side air intakes lifted directly from the R8 LMS racing car. At the same time the exhaust is placed just below tail-lamp height in the center of the rear bumper.

The interior of the car gets Recaro racing seats, a roll cage, and a large downforce-generating rear wing. Next to the engine upgrade, the future R8 RS will also weigh less than the GT and could potentially be rear wheel drive only. This will make the future sports car a serious competitor for the Porsche GT2 RS.
