Those of us in snow prone areas needing xDrive may have an advantage with the 0-60 runs. BMW claims the best times are with AWD coupled with 8AT get you 4.7s....w/o ppk. Hooking up with the extra torque is tough with RWD, hence the 5.0s getting all squirrly with wheel spin as you state. Thanks for the in-depth additional review!
