Alternative Fuel Vehicles

GSA offers a great selection of alternative fuel vehicles for purchase or lease, with more than 1,500 models available and operating on a variety of fueling systems. GSA has been providing quality Alternative Fuel Vehicles (AFVs) to the federal community since 1991. Please refer to AFV guides and helpful links for additional information.

E85 (Ethanol) capable vehicles are able to operate on a blended fuel mixture of 85 percent ethanol and 15 percent gasoline. E85 is an alternative fuel per EPAct 2005. A Flexible Fuel Vehicle (FFV) operates on any combination of E85 and gasoline.

Natural Gas is a clean burning fossil fuel stored in a gaseous state as Compressed Natural Gas (CNG), or in a liquid state as Liquefied Natural Gas (LNG). Natural gas-capable vehicles are available as either dedicated natural gas or bi-fuel natural gas and gasoline. 

LPG (Liquefied Petroleum Gas), often referred to as propane, is a clean burning fossil fuel that produces fewer toxic and smog-forming air pollutants than gasoline. 

Bio Diesel is a form of diesel fuel manufactured from vegetable oils, animal fats, or recycled restaurant greases. It is safe, biodegradable, and produces less air pollutants than petroleum-based diesel. B20 is a mixture of 20 percent bio diesel and petroleum diesel. It can be used in most diesel engines. 

Electric Vehicles (EV) operate on electricity provided by a battery storage system and require the use of a charging station. 

Hybrid Electric Vehicles (HEV) combine electricity and a gasoline, diesel, E85, or FFV fueled engine. The engine is assisted by electrical power provided by a battery storage system. The engine is used to charge the batteries. Most models also use regenerative braking. 

Low-Greenhouse Gas Emitting Vehicles may be considered AFV's if no alternative fuel is available, and EPA provides a Grams of CO2 Per Mile score as follows:

  • Passenger cars operating on gasoline, diesel or CNG – 305;
  • Passenger cars that operate on E85 – 350; 
  • Light Duty Trucks and Medium Duty Passenger Vehicles operating on gasoline, diesel, or CNG – 380; and
  • Light Duty Trucks and Medium Duty Passenger Vehicles that operate on E85 – 425.
