After being at Indy and listening to Andy's and Teuton's 512's go down the track?...It'd take a good part of the day just to get use to that V10 sound. lol Sounded to me like the Red Barron's bi plane during a nose dive. Very similar to a SL/6 with open headers. Joking aside, funny how the 512 V10, 6.1 and 5.7 Hemi's are all natural AA cars. The 2009 AA 5.7 is the only one that can drop to an A. I think the 2010 6.1's with a heavier ship weight are still a natural AA, but are within a 1 hp hit of being a AA only car.
