anything with a short wheelbase sucks in the snow.
audis and subis are better in the snow at over 50mph than a smaller, lighter truck like a tacoma because they are lower and have less body roll. in reality that extra speed from 50 to 60mph in the snow can get you in a lot of trouble. going as fast as you can in the snow is usually not the best way to get there all in one piece. i could go 60 on packed snow all day in my truck if i wanted to..... its just not really worth it
the best vehicle on tires for the snow hands down is a huge, long diesel pickup. dodge, ford, whatever - not a huge lift, maybe a small one. the weight of a bigger truck will help you stick to the snow, the clearance will get you anywhere thru whatever, the long wheelbase will keep you from sliding/make it easy to control sliding.
