You never know how good, or bad, a vehicle and or tyre combination is going to be.
The best 2WD car i ever had in serious snow was an old Volvo 245 estate, ended up rescuing a mini bus of workers going home across the high ground through bad drifting when their mini bus ground to a halt, filled all the seats and the rest piled in the expansive boot, that extra weight helped, we just went for it and that old girl went through without any trouble, that extra weight in the boot did us all a favour, 195/65 x 15 barrow tyres if my memory serves.
Previous Outback on winter tyres was good, but 120 on snowflake stamped all seasons drove out of our steep drive without a slip where the Outback couldn't...but it was later in the day that i twigged i hadn't turned the Outback's TC off.
Talking of surprising vehicles, that winter about 15 or so years ago when everybody got stuck overnight on the M11 Cambs, i was in the middle of a blizzard in Lowestoft with a Volvo FL manual wagon and drag car transporter, 3 axle 5 car LWB prime mover 2 axle 5 car trailer, though i could lift the mid lift when empty, dropped the last car at the Toyota dealer and was sitting facing uphill in about 8" of snow, assumed that was me knackered, sure enough the wagon just dug in and pulled off without a slip.
Took a tortuous route home via all sorts of roads i shouldn't have been on due to M11 and A14 being blocked, passed hundreds of lorries and cars stuck and that motor never caused me a moments issue, even if it was running on 5 cyls by the time i got back about 10 at night.
Another time deep snow in the west mids, i'm in a 4x2 Merc Axor manual tractor with tandem axle double deck trailer, well worn remoulds on the drive axle, again that thing just dug in including reversing up a steep hill into a loading area.
Week later MAN (automated manual) artic, 3 axle unit (mid lift raised) 3 axle trailer, and i'm stuck on a flat road in half an inch of snow, tried rocking it as best you can with a crap gearbox, after about 10 minutes the box overheated and shut down, so had to stop in the middle of the road for half an hour to allow it to cool.
Generally with cars its wide low profiles that can't cope with snow.
Loading new MINIS out of Cowley, compound roughly 6" of snow, those new cars shod on wide tyres wouldn't move (forwards) those lower spec on sensible narrowish tyres no trouble whatsoever, could get the wide tyred models to move in reverse, yet people insist FWD is better.
Wide low profile footprint is completely wrong for snow/slush/ice grip.
Be interesting if we get any snow this year to compare the current Forester on its set of winters, with the 120 on all seasons, but this time i'll switch the Foz's TC off.
