As a rough rule the fewer revs the better.
This helps with reducing friction as well as with the volume of air and fuel being pushed through the engine.
The max power measurement is with the throttle at wide open on a dynomometer and has little relevance to the real world where most driving is done at lower throttle openings. It does help to sell cars though which is why car makers keep talking about it.
Efficiency is , as you say , not a priority at this point only getting the maximum power level matters. Engine life is also not a priority either.
