Huh

If the body is in steady motion then neglecting friction the power
requirement would be zero, since friction varies enormously this
is clearly NOT a valid definition

Quite simply power is a measure of energy production per unit
time or put another way the rate of doing work

The velocity of the engine or the vehicle its mounted in is irrelevant.
