I already posted this on some other ALMS threads, but here's Audi's audi R8 LMS GTE announcement. The car can ONLY race in the ALMS, because of a special rule-exception granted to the IMSA. the car is basically the Grand-Am version with a slightly different restrictor.
Now I'm very curious as to how this thing will perform compared to the existing GTEs. Maybe we should take a look at the Grand-Am test sessions for clues?
