I have a FWD 2005 FEH and it did great in the Denver winter to remember of '06-'07. I've even been off road on Jeep trails with mud and slush and it did fine. The scariest part for me was the different feel of going downhill on steep wet / snowy / muddy trails, since the car always tries to use regenerative brakes first. I felt a little out of control going downhill ( at 20 MPH ) but it was great going up.

Only one time have I used tire chains up front, and that was in a Wyoming ice storm that was blowing cars off the road sideways! But that was like an ice skating rink that day, and the road did close about 1 hour after I got onto it!
