On an unplowed road with nannies off the audi will tend to drift if I crank the steering wheel and stomp the gas while the bmw will want to turn the tail around. That being said both cars driven sensibly are very safe and get you through pretty much anything.

xDrive powers all four wheels all the time. It splits power/torque 40:60 in normal operating conditions.

I did have a mercedes 4Matic from 2004-5 a few years back, that was significantly better and more balanced than my current X-drive. Much more neutral handling, felt like much more even torque distribution all the time, much closer to Subaru.

Fine. Regardless, as stated above, xDrive powers all four wheels all of the time with a 40:60 power split until xDrive senses the need to shift the power around, based on road conditions.
