Alternative Fuel Vehicles

Alternative Fuel Vehicles are designed to improve air quality and the environment by lowering or eliminating ozone-forming tailpipe emissions. GSA owns more AFVs than any single organization in the United States. We anticipate selling approximately 4,000 AFVs in the coming year, including sedans, pickups, buses, vans, delivery trucks and specialty vehicles.

Alternative fuels include compressed natural gas, propane, hydrogen, and gasoline blends containing up to 85% alcohol (methanol or denatured ethanol). Currently, three main types
of vehicles operating on alternative fuels are available:

• Flexible Fuel Vehicles contain a single fuel tank capable of operating on alcohol, gasoline or a combination of both (gasohol).
• Bi-Fuel Vehicles have two fuel systems, allowing the driver to switch between gasoline and compressed natural gas or propane.
• Dedicated Fuel Vehicles can only run on a single alternative fuel source.

In addition to environmental benefits, Alternative Fuel Vehicles offer owners numerous advantages. Many states permit AFVs to drive in HOV lanes and offer tax rebates on AFV purchases. GSA also provides matching funds to agencies participating in the
Federal Government's AFV User Program.
