Default RE: What will get better MPG?

No one is disputing that smaller engines can help with mileage, but engine size Is not the biggest part of the equation. Other factors, such as weight, size, and drag are larger factors. The most efficient cars in the world are going to maximize all these factors, but that doesn't tell you what one is the most important. A large engine can be offset by other criteria and produce an efficient auto. And yes, mashing the throttle on a small engine IS NOT efficient.
Indeed, it's amazing how people forget that the only real relationship between your car and your fuel economy is the weight of your right foot.
