Audi {link} were celebrating the debut win of the R15 on Sunday as it won the Sebring 12 hours. The new car was relatively untested making the win hugely impressive. Even more remarkable was that this year's Sebring race covered the greatest distance at the highest average speed ever, thus the Audi R15 truly had a baptism of fire. The other German car debuting at the Sebring 12 hours was far less successful. BMW's E92 M3s showed great pace in spurts but both Rahal Letterman Racing {link} cars retired before 6 hours of racing has passed.
They were not the only GT2 cars to suffer at Sebring as the expected Porsche challenge never really got started with not one of the Stuttgart marque making it into the top 3 in GT2.
