Really! I went there a couple of times at Christmas and it hit 30 below both times. What do electric vehicles use for heat?
Like everything, their batteries or maybe the itty bitty engines that the hybrids have. Electric only cars that promise to get you 90 miles will get you 10-15 in northern climates in the winter. And it will take twice as long to recharge.....16 hours or so.
Hot and cold weather SEVERELY diminish battery performance (and life).
