Those efficiency numbers are in line with how gas cars vs trucks compare.
My Tesla model 3 typically does 300 Wh/mi (that’s the old way of displaying it) which translates to 3.3 mi/kWh.
My gas F-150 gets about 16 mpg, and my gas car gets about 25 mpg.
So there is a 1.5x factor between “car” and “truck” no matter what your propulsion system is. I assume it all comes down to aerodynamics.
I don’t think the mi/kWh figures will improve dramatically in the future. What will certainly improve is battery density. So we’ll be able to carry a much higher charge as batteries improve. But that will start hitting the limitations of the grid, house circuitry, as well as the utility bill. Solar is going to become more widespread.
