Why do internal combustion vehicle engines require transmission gears to optimize power output but electrical vehicle motors (i.e. cars, locomotives) don't?
Ah, that explains it. Do electric vehicles have any kind of gears or transmissions at all?
Some electric vehicles actually do use a single-speed gearbox, but this is simply to allow the electric motor to operate more efficiently within its optimal RPM range. However, many electric vehicles don't have any transmission gears at all, since their motors are capable of generating a highly usable torque output across a wide range of speeds.
