We're not sure what to make of this R8 GT-based test mule spotted at the Nurburgring yesterday. Clearly the car is a factory mule and clearly it's been upgraded. Here's a quick rundown of the changes we spot.
•*Bigger racing-style front chin spoiler
•*Front and rear fender flaps indicating a likely wider track
•*Small Gurney flaps on rear to each side of spoiler
