Rolling losses get more important than drag losses around cities with low speed and traffic jam. The weight of cars did increase a lot in the last 50 years, but the tendency is down again. The consumption of auxiliaries did increase also but LEDs, improved fans, could reverse the tendency. Knowing the details of rolling, drag, acceleration, altitude change and auxiliaries, the mechanical needs get predictable for electric cars. Knowing all this, with a conventional car, while using 19 tricks, the NEDC listed consumption can be reached in practice. Electric vehicles of less than 150 kg for two persons may be the solution for the future.
