I'm way leary of the whole website. I spect it to be a pile of bogosity. Frinstance the size they give for their 100 plus horsepower 'lectric motator is less'n one foot by one foot by one foot. That there is the size for a normal 5-10 horse motor. And if it went 0-60 in four seconds I think that there'd be all the charge available. Maybe they think it's gonna coast the 250 miles so they be countin' on a followin' wind.
