Have Foci changed a lot? My mk1 estate was ace in snow... Helped that it had the TDDI engine, it made no power but the low-rev delivery was just beautiful, so easy to get its few horsepower down. And the feeble rear drums made braking easier, very little chance of the rears locking up
My Mondeo's a bit of good and bad- 300lb/ft doesn't play so well with snow, it takes very little revs to spin it up in any usable gear. On the other hand, it'll pull along at idle and trundle up some really implausible slopes. And it's a wee bit short on ground clearance so ends up pushing a lot of snow along in front of itself
It has snowproxes on but they're ludicrously wide, 250s (they were very cheap!) So they don't bite too well on some snow compared to a narrower snow tyre. But on the other hand they can get a lot done while spinning, which is extremely satisfying, if not good form.
So all in all... It's kinda rewarding, but kinda hard work. Almost wish I could switch to the standard map sometimes and get back the weak bottom end.
