I’m not using my Prius as plow, but even when I had a Honda Ridgeline AWD, as long as I had clearance underneath the car and snow and ice, I would drive my Prius on my hundred mile round-trip to work. Yesterday I was trying to get my daughter and other college kids unstuck from snow and ice in a parking lot with a pretty steep incline. I laid down about 400 pounds for traction and my Prius never got stuck, but and trying to show my daughter how to drive and get out of the parking lot uphill, the 2010 Camry always struggled. I was surprised because it has new tires with better tread. It even weighs probably 200-500 more, and it thought that might help- but not at all. Maybe it depends on the displacement of the weight. Just to add to the “Prius instead of a truck” discussion that some have had, I am actively looking for a new to me Ridgeline after mine was wrecked, but my Prius has been unstoppable in this snow over the years .
