Also there is a very confusing case described where on glaze ice, when the rears both have zero traction and the fronts have some, BMW says xDrive sends almost all TQ to the front, which is impossible unless you write science fiction for a living. Or write politcal speeches.

Haven't heard about the low speed thing...not doubting you though.
I've heard the front disengages around 70mph.....again can't confirm either.
I don't know about your last statement lol....I do agree though. How can 100% of the power go to the front if the rear is always engaged?
