A mysterious Audi R8 has been spied undergoing testing on the Nürburgring Nordschleife.

Reportedly a facelifted version of the R8 GT, the model is equipped with a prominent rear wing and a sporty rear diffuser.

There's no word on performance specifications but the previous R8 GT had a 5.2-liter FSI V10 engine with 560 HP (412 kW) and 540 Nm (398 lb-ft) of torque. It was connected to an R tronic transmission but the new model should adopt a seven-speed S tronic gearbox for faster gear changes and improved acceleration.

There's no word on when the model will be introduced but Audi has already confirmed the next-generation R8 will go into production in mid-2014.
