In a low traction environment, non xDrive only has its electronic traction control to help get the drive to where it can be best used whereas xDrive has both the centre clutch pack and ETC. With xDrive, it's only under extreme conditions that all the drive is directed towards the rear wheels.

what is not correct , what are you trying to say ,seems like you just added more words to what i already said , none if my info is incorrect ,it says in the X3 handbook that it utilises rear wheel drive predominantly .
the xdrive vehicles feel more like a rear drive car .no big deal because the 38% 62% car is fine . the xdrive does potentially offer better traction options if you get really stuck .
i almost got stuck on a very narrow cobbled steep hill in Edinburgh whist turning car around i had to reverse uphill but one rear wheel spun on dry surface , you need to press the dsc button to make traction control work whereas the xdrive would shift more drive to front wheels in that event thus saving embarassment .
as for sport suspension , it`s not comfortable on anything less than a smooth road , not good to be pounding a baby , i know what i`m talking about . x3 sport has the worst suspension i have ever experienced , x5 sport nowhere near as bad .
