Yes, power required varies as the cube of the speed. But, if you go twice as fast, you will get your trip over in 1/2 the time. So the energy required for a given trip will vary as the square of the speed.
The point of maximun torque is the point of maximun efficiency? Perhaps from a thermodynamic point of view, but this real engine's torque peak is determined by a computer, not thermodynamics. Where is the post that showed the efficiency peaking at around 2600 rpm? Yes, that was for a euro engine, not a castrated unit for the north american market.
