A/F = A/F. The only way to get better mileage is to use less of both which means less power. Displacement, and forced induction use more of both.

Not true. Every year (well, with every new engine) the manufacturers get better and better at extracting more power from each mole of air-fuel mixture. why do you think we now have so many 250+ horsepower cars that get 25-30 mpg? Remember when 250hp was an unthinkable number for a "normal" car without a V8? Subaru went from turbocharged 1.8s that made 115hp to NA 1.8 that makes 118, 2.2 that makes 142, and 2.5 that makes 165+. Then there's the turbo EJ25 of the current generation. Combustion technology is definitely venturing into the land of diminishing returns as far as power and efficiency gains, but we haven't perfected it yet.
