Koenigsegg CCX is fastest on that big oval track, just a little faster than Zonda R, and thats it. its slower on every other track.
for Drift, its personal preference and tuning matter, so i wont comment here. any car with Drift ability should be able to win in Career Drift Events.
Also, it seems like no matter the cars you use in each tier, you can win the game, beat NFS LIVE championship etc.
you can beat single player with just any cars, excluding American / Japan / European car requiring events
