Mysterious Audi R8 LMS tests at Monza

A few weeks ago Audi Sport was testing at Monza what it could be the next-gen of the Audi R8 GT3 (2015-2016?). Hearing the sound the engine is for sure the V10 engine used on the current R8 LMS but with a different exhaust position (now the two tailpipes are still in a central position of the rear but they are away from each other, like a Ferrari 430 Scuderia). The gear changes seem much faster than the actual R8. The camouflaged body is very rich of air vents on the rear and it has a quite big rear diffuser.
