Ye, different engine (32v 302hp versus 16V 260ish), bigger brakes, different suspension tunning.
My experience with the Ave has been good in the snow. While driving along it is very predictable and handles well. Braking is tougher because of the weight, but the tranction control turns on and helps. I was however dissapointed with it's ability to get out of a few tough situations after being snowed in heavily. I don't think many other vehicles would have gotten out either though. The scenario: parked on a decline on grass, with about a foot of snow. The ave would not get traction and could not climb out, my guess because of the grass. It was digging itself in, but I doubt other vehicles would have had much luck. I think in the '05 (my year) you can lock the AWD into 4WD mode. I rarely use it, even in the snow, but I thought I'd throw it in. So all and all I am happy, and my last 4x4 vehicle was a 2001 Jeep Wrangler Sahara.
