Is pretty damm impressive. I've had my new to me P85 for just under 2 weeks now, and we've been hit with a few snow falls since. The car is as sure footed as a mountain goat in snow and icy conditions despite being back wheel drive. It is pretty difficult to make the car loose control even with the traction control off. I can only imagine how much better the D cars are. The only thing I found I had to do was to put the car on low re-gen or the back end wiggles just a little while slowing down on super slippery roads on which I should be driving slower anyways. I look forward to driving the car everyday and look for any excuse to get behind the wheel.
