The range is stated to be 100 miles but with braking, coasting and hyper miling that range can increase. The rep we had said that in CA one owner had his up to 138 miles.
Also they said that the average daily driver is under the 100 mile range. I have to admit I am very close to being near 100 miles per day.

I see people out there spending money on the car to improve it … If you spend half that effort just working on your driving skills, making you and the car work together as a team, then you’ll go faster – period. To make the car go a second faster on the track takes a lot more energy and money than making yourself drive it one second faster.
