Alistor...Did you perform the test I described? Forget your reasoning, go try it in practice.

Can we agree that a constant acceleration is achievable with an engine that features a flat torque curve throughout a normal operational range?

Then can we agree that the acceleration in the lower half of the rev range uses less fuel than the top half of the rev range due to lower RPMs and swept volume per minute?

Can we also agree that we are producing less power in the lower RPM range.

Can we now agree that with a flat torque curve it is more economical to drive in the lower range if torque is constant?

Can we also agree that using an engine with higher torque down low provides enough pulling power to select a taller gear earlier and/or a taller final drive ratio, which then reduces engine RPMs and thus reduces fuel consumption.

And finally can we agree that higher torque in the lower RPM range provides good acceleration and performance, and we are able to use a taller gear ratio which reduces RPMs and fuel consumption.
