Front wheel drive, and a competent driver, can make it around pretty well in most conditions.
The only thing that ever stopped our old VW Rabbit (1976) or Mazda 323 (1988 ) was if the snow was deep enough that the flat underside of the unibody construction would plane up on top of the snow and lift the wheels out of decently weighted contact with the road surface...took about a foot unless it was really light dry stuff which didn't hold the car up, and which we usually don't get here on the west side of the Cascades.
The Subaru Forester (2010) is amazing...just about unstoppable, with the symmetrical AWD.
