To those in this thread that doubt the validity of the OP's claim... I drove the Nurburgring in an E92 M3 this past Labor Day. I watched people in Aston Martins, Ferraris, Porsche GT3s, GT-R's etc. blow past me at triple digit speeds on some of those corners. They didn't flip, crash themselves or cause anyone else to. The physics needs to be fixed. Jabofu and the_kingb_ are still right in their assumption about the engine not working correctly. So since this is a game and NOT real life, I asked someone on the forum who actually drives race cars in real life for a living to chime in. Hopefully he'll reply with his feedback on Monday when his copy of GT6 arrives.
