I side with Ron. The the Audi was fast due to beign the first real race car at that level with desiel. The the restrictions were not as strict as the gas powere rivals. Audi also leveraged a chassis that had been dominante for several years were there was no real competition. I would believe it if Audi built the diesel R8 and raced it in GT2 were just about every manufacturer with a REAL history in international roadracing competes.
