I don't think they are trying to say that 55 is a magic number. They are just trying to get people to slow down. Force balance at a car moving at a constant speed. If it's not accelerating then the forceput to the ground at the wheels is equivalent to the sum of te wind resistance and the rolling resistance of the wheels. You are absolutely correct in saying that the motor has certain RPMs that it will operate more efficiently based on its own parameters, but this is a secondary order effect when compared to the energy required to make up for the resistance losses.

I would take you up on the offer to see if te ga mileage is better at 55, but I have a hard enough time keeping it at 75.

I will try it in my dodge 1500 that thing takes forever to get going.
