I'll be replacing my car within the next year and the Rav4 Hybrid is back on the top of the list. I live in Northern Illinois and don't have a garage, so my car sits in a driveway or on the street year round. I've seen posts about how the hybrid drives in the snow or how gas efficiency is down during the winter, but not about the effect of the hybrid sitting in cold and snowy weather. I'm assuming it's better for the battery than brutal heat, but I'm just wondering about the long term effect. All the hybrid owners I know here are able to keep them in garages, so I have no one to ask.
