If I were in your shoes, I would be shopping for a car instead of an SUV. They are harder to roll. I would also get something with VSA (or its equivalent ASM- automatic stability management).
At the risk of offending you…I think you are wrong. Acceleration is not a safety feature. If you find yourself in icy/snowy conditions, trying to get ahead of everyone else is a good way to cause a pileup.
Tires are 98% of winter driving. Four REAL WINTER TIRES (e.g. Blizzaks) NOT all-season tires are the key to winter driving and more important than AWD or 4WD. I’d drive my RWD BMW with four good winter tires over a Subaru with all-season tires any winter.
