My old 5spd AWD Suzuki sx4 had a clutch based center diff for the AWD. It had a 2wd/auto and 4WD lock for sticky situations that would disengage at 30kmh or so.
That thing was a tank for what it was when you had good winter rubber on it. I plowed through snow that was at license plate level just below the headlights and it took it like a champ.
This car is no wear near as capable but beyond crazy snow storms of that caliber I managed just fine every day last season except for one.
The car dragged it self out of this mess with out much fuss. Some revs in reverse and about 20-30 seconds. Compared to a coworker with a genesis which spent 40 minutes to do the same.
