CAFE wouldn't be an issue if there was any way in the world an automotive V-8 could obtain 100 mpg! The car manufacturers would be all over it. The internal combustion engine is rapidly losing opportunities for big gains in fuel economy. It is pretty well engineered in the modern engines. AFM (active fuel management, ie dropping cylinders under light loads) and start/stop technology are a couple of the latest gains after going to lighter lubricants. Concentration has been on lighter and slippery cars as well as less and less displacement. We are still buying V8 vehilcles because we want/like em and gas is cheap.

You can pick up a couple thousand BTUs/gallon in the winter by storing some summer formulation gasoline.

just my 2 cents
