F30 / F31 / F32 / F33 / F34 / F36 (2012 - current)
My son and I will be driving my 435ix, 2015, 35k miles (with performance exhaust package) at Watkins Glen later in June. The car has a couple sport settings, and traction can be disabled.
I'm not certain what the speed limits will be but I think the limits will be higher than those imposed on...
