From second-hand-but-reliable sources, what drags down the RAV4 Prime are the compromises necessary for it to be built as a FWD ICE, AWD ICE, FWD hybrid, AWD hybrid and Prime versions. The engineers I've spoken with say if Toyota had designed the Prime from a clean sheet, it would be lighter, roomier and drive/handle better. Of course, with the lower volume production, it probably would also cost more.
FWIW, a family member has a Tesla M3 AWD. With snow tires, it's OK on plowed roads, but the low-slung sedan will high center when drifts are more than 6".

We've lived in the frozen-ass-end-of-nowhere for almost fifty years and have snow tires on our Bolt. And yes, FWD with snow tires is OK until it isn't. Last night and today we've gotten almost a foot of snow. It's doubtful the Bolt will be able to negotiate the unplowed side streets. When the winter trip is going to be through the mountains and hundreds of miles from the nearest tow truck, AWD and higher ground clearance is a must if one is to have any chance of making it.
