BMW has come up with a relevant commercial for the cold season. Boasting the capabilities of intelligent xDrive four-wheel-drive system, they show us a BMW X6 pulling a Snowcat up a steep hill without breaking a sweat.

Being a BMW product, of course, the xDrive system is mainly designed for driving pleasure, which means it is four-wheel-drive only when it needs to be. It gets the job done, no doubt. But still, if you deal with rough terrain on daily basis, you are better off with a Range Rover.
