If you are referring to efficiency for on-road applications, I would guess not. If you are referring to using it to move heavy object and such, I would point to a crane and say "they already have."
MORE POWER

To increase power of the motor, by increasing airflow thru the motor(higher volumetric effiecency) when needed.
rev hard and increase engine pressure.
A: No problem but don't expect the power to increase
The potential flaw in using Pascal's Wager as a basis for belief in a higher power is that it assumes belief in a higher power is a safe bet with no downside, but it overlooks the possibility of other beliefs being true or the negative consequences of believing in a specific higher power. This is known as the Pascal's Wager fallacy.
An electric car is normally powered by a motor, but can be driven with gas turbines, or jet engines, to either increase the range or feed power directly to the wheels.
Pencil lead applied to the moving parts will improve performance by reducing friction. This may or may not increase the speed of the motor for a given power supply.
Power factor reduces overload capacity increased noise reduces
The power output of a motor can be changed by the use of gears. Gears can be used to increase torque by reducing the speed of the output shaft by placing a large gear on the output shaft, coupled to a smaller gear. Conversely, by using a small gear on the output shaft, coupled to a larger gear, the speed can be increased with a reduction in torque.
When starting a shunt motor, it's essential to ensure that the motor is properly connected and that all safety measures are in place. Check that the power supply is stable and that the motor’s field winding is functioning correctly to prevent overheating. Gradually increase the voltage to avoid a sudden inrush of current, which could damage the motor or the power supply. Additionally, monitor the motor's temperature and current to ensure it operates within safe limits.
An airplane is a VEHICLE. It's power is provided by a MOTOR.
