A pair of Audi RS performance cars have been caught testing and show what the German brand has planned for these ultimate examples of the TT and A5. The TT-RS was snapped in production ready form and shows off some serious design tweaks including two gaping intakes flanking the already gaping corporate Audi grille, chunky fender flares at all four corners and a pair of large oval exhaust tips embedded in the rear bumper. Powering the TT-RS is expected to be a twin-turbo 2.5L five-cylinder engine producing between 350 and 390 horsepower, which will easily make it the fastest production TT ever.

The next car is the RS5, and less is known about this model since it was snapped wearing the guise of an S5. Caught on the Nurburgring in Germany, this RS5 mule is wearing an RS-inspired front end, but confuses the camera lens with its lacked of flared fenders and quad exhaust tips where one would expect an RS model's typical dual ovals. Still, there wouldn't be much of a reason for Audi to test the current S5 on the 'Ring, so what we're looking at must be an RS5 mule. What will power the RS5 is still speculation and could be either the 4.2L V8 from the RS4, a twin-turbo V8 or the Gallardo-based V10 from the RS6.
