Flex fuel, or E85, has been developed as an alternative fuel, with a composition of 85% ethanol (primarily made from grains) and 15% gasoline. Automobile makers, such as General Motors, are manufacturing vehicles that will run on E85 in addition to gasoline. They remain committed to E85 as an alternative fuel, which will continue to become more prevalent as General Motors makes more flex fuel cars and more stations offer E85.
