For fun, I fired up Gran Turismo 4 and modded a Viper to as closely approximate the ACR as possible (soft street tires, adjustable suspension, 600 HP, upgraded clutch, some downforce). It took me maybe 10 laps or so, but I got it down to 7:24, and it could go lower with a better player. Obviously one can take risks in a video game that you can't in a real car, but I made a few mistakes that cost time, too. There are always going to be inconsistencies in track and car modeling, but I thought it was pretty amazing how close the results were. If you attack the 'ring in a 600 HP Viper with downforce, you get low 7:20's, whether in real life or the game. :thumbsup:
