ICE vehicles can get much better HWY economy than City, even at 80mph because of transmissions with 7 or 8 gears now that keep rpms down. I wonder if the range on the MS wouldn't take such a dive at fast speeds if the motor could turn much slower at highway speeds with an overdrive gear? I realize it would make the transmission more complicated, but I wonder if a 2-speed transmission would change anything. Obviously wind resistance increases exponentially with speed, but with so much torque at low rpm, would the motor use less electrons at half the rpm? Any electrical engineers care to comment?
