The fastest car in GT3 0-60 is the F094/H and the fastest car top speed is the Escudo, Ive had it going 291 mph after drafting a car in an F1 race. The Toyota GT1, although a very good car is not the best. 1350 bhp to only the rear wheels makes quite a bit of understeer. The tail will come out in any gear unless you use level one TCS. The 787b is excellent for long distance because of its handling characteristics it tears up tires very slowly. I have made it to 95% complete in the game and I must say the best car is the 787b. I must say the Zonda race car is also very good.
