Really? You are asking for IRB approval just to fill a random survey on Google forms? You are definitely being too difficult.

Besides the constant power requirement you have, which basically doesn’t change no matter what you put around there, motor systems used in EVs are quite “sophisticated” in terms of how much you can control them, which doesn’t exist at all for combustion engines. Depending the power demand you have from the car at any given instant, the controller can set the motor to provide the torque and the speed at the highest efficiency point, which is super interesting.
