Thanks Funkhoss, your numbers speak for themselves. Conservative driving with engine-off coasting can go a very long way, and anything to keep RPM down, vaccum low and load high is going to improve efficiency.

It depends on how the motor is wound. It might be 1000rpm, or 200rpm, it just depends on the motor. I was trying to communicate the shape of the torque curve for electric motors, that particular graph doesn't apply exactly to all electric motors. Ignore the numbers.

Anyway, the stock tires on your car have a circumference of 82.2 inches. A hypothetical hub motor that tops out at 500rpm at 24v will move your car along at 39mph, but will have a top speed of 78mph at 48v and 156mph at 96v. Electric motors play by different rules than gas engines do.
