Why don’t electric cars have transmissions?
"Electric motors do not have the same limitations as internal combustion engines. They produce the same amount of torque at near zero as they do at high rpm. Turning slower does not use less battery power. The load is what determines how much power the car uses. Eliminating a gearbox also has the advantage of eliminating weight and gearbox losses, which makes the load smaller. And finally, doing so conforms to a long standing wisdom that engineers often forget. It called the KISS principle."
