I'm in New England and I'm seeing 100 miles with a full charge in the summer, down to 85 in the winter. Mine is in a garage at night, which may make a difference.

That said, that's just what the car estimates. I can get close to that number if I stay off the highway, but I do think it's a bit optimistic. I typically come in between 5-10 miles less then the estimate.

I live in Vitoria, BC. It doesn't get that cold here, but it was below freezing I lost maybe 10% of range. It takes maybe 3 hours to change with my level 2 charger.
