Current Alternative Fuel Vehicle Models: DoE guide to hybrid, CNG, and ethanol vehicles, including information on prior year models and links to used car sales.  Many flexible fuel vehicles taking any mix of gas an ethanol up to 85% ("FFV E85"), at no extra cost:  22 sedans, wagons, coupes, and and light trucks from Ford, GM, Chrysler, Mercedes and Nissan.  Industrial vehicles, including buses, garbage trucks, and construction vehicles also listed.  Biodiesel covered separately: "Fleets looking to comply with the Energy Policy Act of 1992 (EPAct) must use fuel blends that contain at least 20% biodiesel.  .. Using biodiesel blends requires little or no engine modification .. In older vehicles, high-percentage blends of biodiesel (greater than 20%) can affect fuel hoses and pump seals made from certain elastomers. The effect is lessened with lower percentage blends. Elastomers (found in hoses and gaskets) that are biodiesel-compatible are required for use with B100 and high-percentage biodiesel blends. "  8:45:30 AM
