Tesla Model S P85D
As one would expect, the Tesla Model S P85D, thanks to its all-wheel drive, performs very well in the snow.
Here is sample video uploaded by one of the first owners of the P85D, who not only drives it through snow, but also up a 16% grade starting from standstill.
The video uploader states that he wouldn't even consider doing this from a standstill in a P85, so we assume that differences between the RWD Model S and the P85D must be significant.
"6" of fresh, wet snow and a 16% grade are no problem for the P85D with Nokian Hakka R2 Snow tires."
