I haven't unlocked all of the upgrade parts yet, but for right now this seems to be the fastest car in the game on the Loop. It's really twitchy and tough to drive compared to the other cars in the game, however it's very fast. I'm surprised that it's faster than the NSX Type-R, but it is. The 4WD cars like the R24 GTR, the Lancer Evo VI, and the Subaru Impreza B22 are way easier to drive but much slower lap times. The RX7 and the Supra don't have the speed to match the NSX either. I haven't unlocked the Viper or the Devil Z yet. I'll try this again once I've unlocked everything. Also I made a lot of mistakes in this run, could probably get it down to 3:20 or even just under if I didn't make any mistakes. What's your fastest time on the Inner Loop?
