  • Yeah, friction losses scale with angular velocity and not torque, and moving a ton of metal takes torque. Don’t forget the braking losses, though, unless it’s a hybrid of some kind. There’s no turning movement back into fuel the way you can turn it back into electricity.

    The point is if you’re looking good range, there’s several dials that can be adjusted on an ICE car, related to the prime mover. On an EV, drag is the start and finish of the considerations (unless you’re going to move it onto rails, maybe). And of course range is a huge deal, because a liter of secondary cell can’t come close to the energy density of a liter of petrol and 38 liters of ambient air.
