I am sure you have all seen the test of the 3 modes of ESC, but here is my review on the total car when being used in winter conditions. I had a good 3 weeks of constant heavy snow to really learn how the ST reacts. Living along Lake Michigan, we get around 120" of snow a season, and this year the snow has been falling constantly with some totals being 7" per day. Temps have been way below average as well. The few weeks I had with the car are a good representation of a normal winter season.
