The U.S. Environmental Protection Agency could soon issue a final ruling that aims to force oil companies to replace E10, gasoline mixed with 10 percent ethanol, with E15.

This move could come just as widespread support for ethanol, which is made from corn, appears to be eroding.

Mike Mitchell was once a true believer in ethanol as a homegrown solution to foreign oil imports. He owns gas stations, and he went further than most, installing expensive blender pumps that let customers choose E15, E20 and all the way up to E85.

More than 20 state governors are taking an unusual step to boost the natural gas vehicle industry. Independent of the federal government, they're asking Detroit carmakers to build them a new kind of car: a midsize sedan that runs on compressed natural gas instead of gasoline.

The governors are hoping to boost demand for natural gas cars with their collective buying power. Combined, the states say they could ultimately buy thousands of CNG vehicles to replace their current vehicle fleets — if those cars were available.

Ford Motor Co. intends to prove that good things come in small packages — really small packages. The company has taken engine downsizing to a new level with its new three-cylinder EcoBoost engine, which has been introduced in Europe and is set to hit the U.S. market next year.

The EcoBoost offers more power than many conventional four-cylinder engines, with fuel economy numbers a hybrid could envy. Early fans are calling it a modern "little engine that could," and Ford is betting that American customers are ready to embrace a three-cylinder engine.
