compared to a regular car
Do you mean 'full size' or 'compact' car ?
Since the Tesla is a full size car then we have to compare it to a full size petro burner.
The Tesla has about the same range as a petro burner of the same size. (550 kilometers)
And the electric vehicle actually has much more energy then a petro vehicle as we saw when they hooked up a Tesla pick up truck to Ford pick up truck (same size) back bumper to back bumper and the electric Tesla truck pulled the Ford truck down the road with the Ford truck helpless to the Tesla over powering torque.
