      It’s correct though.

      ICE efficiency in a car ~ 20% for a car, gas to wheels.

      Worst case scenario :

      • diesel running to generate electricity (the engine stays at its efficient point): 45-50%
      • battery efficiency to charge 85%
      • battery to movement efficiency ~85%

      Electric cycle efficiency : ~33%

      You need to add ~15% overweight for EV, making a conservative 28% total cycle efficiency.

      It is definitely the energy density which makes the difference.
