This made me chuckle.

Faster response times, same torque split. The xDrive in these SAVs are more electrical and "take some time" to engage in bad climates. I exclude the X5/6 Ms because they have a torque vectoring rear diff like Audi sport-diff cars.
I'm really looking forward to putting xDrive to the test this winter to compare to my old Q7's Torsen system. It just needs to snow soon
