Playing a bit more jumping between each car I've noticed...
Porsche - Fastest Acceleration, lowest top speed attainable using boost. Balanced through the corners. Probably best for newcomers, but I don't think it will set as fast of a time as the others in the demo level. My fastest time is a 3:22.xx
BMW - Good Acceleration, higher top speed than the Porsche using boost. Easy to oversteer through corners, easy to drift but can cost you speed if your not paying attention. With practice very quick, good all rounder but requires some skill to get the most out of it. My fastest time is a 3:21.06
Nissan - Poor Acceleration, fastest top speed (highest I've been is 294kmph) using boost. Heaviest through the corners and shaves speed off like its nobody's business. Hardest car in the game to go quick with, although I think this car on the demo track could probably set the fastest times. Have to be ultra smooth and just maintain a high speed throughout the circuit, I don't think it could be caught, although thats much easier said than done. My fastest time is a 3:21.77
For the 3 cars, they are all fairly even, even with their differences, it would come down to the best driver on the track in the race would come out on top regardless of car. For time trial, I would have to give it to the Nissan, although I'm yet to prove it myself, I believe the Nissan will yield the best times.
