From what I understand, upgrading a 2 wheel drive EV to a 4 wheel EV isn't a horribly hard thing to do.

Driving on snow/iced doesn't require power, it requires good tires and an understanding of how to drive on snow and ice.

I do wonder if the engine in it could get up Seattle hills though, my family's old Geo Metro had problems, so something with a fraction of the power could prove problematic.
