Haven't been through a winter yet but it's pretty good actually. Went on a 190 mile trip and it estimated I'd have 10% when I arrived but as I was on the highway on cruise it kept rising and when I got there it was at 29%. It does have a heat pump so I think it'll be decent in winter. Really don't even want to sell it, I'm loving this thing. It's fast, roomy and beautiful. I may just keep it.
