Also bear in mind that in the winter the real range is more like 150 miles (100 to 0) and 20-80 range is about 100 miles if you don't want to tax your battery every day. My round trip commute is about 45 miles and I can probably do 2 days before topping it off this time of year. Short trips are the worst for efficiency, you can easily use 10 rated miles on a 1 mile trip due to cold battery and car. Takes about 10 miles to of driving warm up the battery fully.
