If one orders adaptive drive, then as far as I can tell with the exception of shadowline trim, the headliner, and the sport wheels they are the same. Changing the limiter (increasing max speed from 130-150) I don't think kicks in until you get the 20 inch wheels with performance tires. (I believe the tires are same on the sport/non-sport and only the rims change until you get to the 20 inchers.)
