No better or worse than any other front wheel drive car I've owned. It can be unstable when driving through snow that's suddenly deeper than the front bumper.
But overall, I'm satisfied with its winter performance. Just get some good tires for it and keep a cup of non-clumping cat litter just in case you get stuck.

Here's what you get with no snow tires and bald all seasons:

And in case you're wondering, no, you can't push a high centered 4100 lb sedan free in a Nissan LEAF. If I had cat litter under my wheels, maybe. It definitely has the torque, just not the traction.
