Thanks for your article. The electric equivalent of MPG values, or eMPG, has probably some mileage, as people can relate this unit. On the other hand, as European and supporter of SI units, I would have hoped that the world could move on to those and its derivatives, e.g. kJ/m, the energy spent in kJ for moving a vehicle by one meter.
