hence why I used such an extreme example (cars these days dont even have 4 spd)No, it's like saying the extra weight of the 9spd produces enough of an efficiency gain that the range of the car is better than had you just added more fuel capacity equal to the gain in weight. The 9spd keeps the motor in it's most efficient operating range better than the 4spd, by a lot. Electric motors give up less than ICE motors across their RPM range at a given amperage input, by a lot.
I dont know why you ask a question (a dumb one at that) and then get the answer and claim the answer is wrong.
