Our 2013 Tesla S85 RWD with Nokian R2's worked well in the Ontario snow storm on Saturday, drove 35 minutes one-way to a recreation center, no worries, even plugged in to a Tesla destination charger on site, super!
Came back out to see the car embedded in a snow bank pushed into our car from a private snow plow contractor no doubt.
With traction control on, and low suspension, couldn't get out, so disabled traction control, raised suspension height to max, floored it and OUT, no worries.
Drove home with traction control on and ride height normal, did "snow plow" some deeper snow on the street, no issues for us, but did see a bus crashed into a pedestrian cross walk sign, another half dozen cars stranded, and one crazy thing, a car attempted to turn right into my lane, I let off (and regen'd), and he finally saw me coming over the snow bank and realized he should have been more cautious, so he steered his car right onto the sidewalk and high sided it in the snow bank, didn't even make the turn...strange.
For fun, I did disable traction control on a 4 lane local road near our house with no one around and did some donuts in the >10cm of snow.
My son regaled my wife with the story of the donuts and how dizzy he got ... sigh, thought we were keeping that one between the boys, but oh well (it is her car by the way!!).
Tesla makes a great winter car.
