Well other than rear wheel drive supercars, I can't think of any car that is crap in the snow. I drove my Focus ST in the snow we had in the NE of Scotland last year without incident.
Depends on the severity of the conditions. There were few cars out on the roads we were using this year. I watched one have to be pushed/gritted/fed branches as I drove around it and towed another two out.
You can drive a lot slower in a 4×4 too. Snow driving in a 2wd relies a lot on momentum.
I wasn't talking about tackling hills, I was talking about being able to slow down and stop.
Yes, you confused me. Driving in snow is about controlling your speed. A 4×4 allows you to control your speed a lot better than a 2wd. If you don't know this and drive fast you won't be able to stop. You are correct, if you can't drive in the snow to start with a 4×4 will just let you crash faster.
None of this is very relevent of course. Chances are we won't see snow again in a generation. But back to my wife's criteria, she does like a car that works in the snow. Kind of like why people wear helmets. Chances are you'll never need it.
