I’ve owned two EVs, and that instant torque is much more of a pro than a con, even in the snow. Think about traction control: when the computer detects a loss of traction, it cuts power to the motor until it detects traction has been regained. In a gas powered car, you can really only change the flow of gas a couple times per second, because there’s some delay between applying throttle, waiting for ignition, etc. But in an EV, you can modulate the power upwards of a thousand times per second, and it gets applied to the wheels practically instantly. So when you slip in the snow, the traction control can react far faster.
My first EV was RWD and I would say that winter performance was comparable to my FWD sedans that I drove before, because the weight is distributed much more evenly, and that traction control is amazing.
My current EV is AWD and even on all season tires, it’s insane. Obviously no powertrain helps you stop if you don’t have snow tires, but for starting off in rough traction, it’s insane. Comparing my car to our Honda CRV, it’s wildly different. I can basically drive the car like there’s no snow on the ground (except I leave a massive gap in front in case I need to stop). The CRV slides all over the place
Sorry for rambling, I’m just a bit of an EV evangelist, and snow is somewhere that they really shine
My experience has been that on steep, snowy roads heavy EVs struggle. It could have been that they all had the wrong tires but going up Berthoud pass I’ve seen a handful of Tesla Ys and Xs doing their best Tokyo drift impressions trying to just get up the hill - virtually zero traction and sideways struggling to even stay moving much less staying in their lane
I will say my FWD EV isn’t as good in snow as my old AWD/4×4 Jeep, or even my old Ford Taurus. I do notice the extra weight in snow, and the centre of gravity is closer to the battery pack, not the “engine”, at least middle not front. I think a RWD EV might be a little better.
Still, just drive to the conditions. I’m not going to cross the Coquihalla or the Malahat in winter conditions either.
Yeah, heavy cars definitely do worse in general, especially if they’re on shitty tires. I’d love to get snow tires but we only get two or three days a year where the weather is bad enough to justify them, and they’re too damn expensive, so we just stay home when the roads are bad
That’s only half of what traction control is. The other half is applying the brake to the slipping wheel to divert power back through the differential to the stuck wheel. That braking control is electric, and while I don’t think it operates with PWM, it can be applied many times per second.

Weight is good on snowy roads in some circumstances, but not for going up hills.
