There are online calculators where you can enter the vehicle Cd and frontal area, and it will calculate HP required for a given speed. Find a car with an efficient aero shape, and then plug the numbers in to find the required HP. The amount of power needed at the target speed should be 35% of max horsepower, and the gearing should be such that the horsepower is achieved at 75% of peak torque.
Yes, fairly complicated.
EVs operate between 85-95% efficiency throughout the range, so they are good for just about any speed or operating condition.
