True, and a good point to mention. A car (for instance) would have a power-plant component and a drivetrain component. However, weren't the drivetrains and engines also rated by wattage and thrust, but not horsepower? Or am I misremembering (it has been over 20-25 years, so I have no illusions that I remember this all perfectly).Just to put this into context for those not used to GURPS the power plant is a different system to the engine. But the power plant rules were written for consistency with the battery rules which were always in kilowatt-hours
