Before Audi went on its astonishing run of success with the R8 and later R10 prototypes at Le Mans it built the R8R.

The car was entered in the 1999 12 Hours of Sebring and 24 Hours of Le Mans. It wasn't hugely successful, but it bettered the British-built R8C, which was a similar coupe prototype.

The open-topped philosophy was chosen, the R8C project was abandoned and the R8R eventually morphed into the now-legendary R8.
