I have an xDrive with manual (N54 tho). xDrive and winter tires in PA is like cheat codes. Very fun to lay into the throttle and just put power down. One thing I noticed is that with TC off, there's no post shift bog. The few times I've gotten it right it scared me.
Full disclosure: I just have a "stage 1" Cobb OTS tune so my HP is relatively low compared to most others out there.
