Regardless of theorical efficiency or not of the energy, in practice the ICE gets the torque needed by the vehicle for driving on all types of slopes (and speed, by transforming part of that high torque with the gearbox). This is why electric and combustion vehicles have such different ranges at even the same weight. Nowadays. Such high torque is needed at the same moment the vehicle doesn't circulate on a flat terrain, or when have to reach highway speeds. For to get at least the same ranges, the electric vehicle must reduce the energy consumption for the generation of the required torque (and speed), or needs to increase the energy density of the battery in companion of increasing the recharge cycles. will be possible to achieve this? of course. (The losses cooling or heating the battery and avoid the self-discharge should get the same advances, as it's counted as stored energy but it's not used for motion)
