I suspect the answer has something to do with amp hours. this verys with speed and thats one of the things that makes EV driving so much fun .

Most EV'r estamate there range conservatively (unlike gas car ) I'd bet that if pressed to the wall most could go twice as far as they say .And then there's the Littlefield delorian re ok...:) > > Again, thanks in advance. > > > Bruce > Chapel Hill, NC > > "Dead fish go with the flow..."
