Other Alternative Fuel Vehicles
Please see hybrid electric vehicle section of Electric Vehicles, bi-fuel section of Natural Gas Vehicles or bi-fuel section of Propane Gas Vehicles
Flex Fuel Vehicles
Flex Fuel vehicles may be fueled by gasoline or E85 (blend, 85% ethanol, 15% gasoline). There are millions of flex fuel vehicles on the road today and achieve comparable performance results to conventional gasoline vehicles although fuel economy is lower when running on ethanol.

Natural Gas Vehicles
Natural Gas vehicles are either fueled exclusively by natural gas, compressed (CNG) or liquefied (LNG) or by natural gas and gasoline in a bi-fuel natural gas vehicle, also considered a hybrid vehicle. While a dedicated natural gas vehicle performs better and have lower emissions than hybrids, both, with the exception of driving range, perform better and have lower emissions than conventional gasoline vehicles.

Propane Gas Vehicles
Propane Gas vehicles are most popular as fleet vehicles, taxis, police, or delivery vehicles. Propane gas vehicles may be fueled exclusively by propane or, with a dual fueling system, may be fueled by propane and gasoline as a bi-fuel propane gas vehicle, also considered a hybrid. The hybrid has comparable performance and driving range to conventional gasoline vehicles while the driving range of the dedicated propane gas vehicle is typically less; however, both dedicated and hybrids have lower emissions and they have lower maintenance costs. Additionally, engine life potential is twice that of a gasoline engine and there are no cold start issues because the fuel is gaseous. Click here for more information.
Fuel Cell Vehicles
Fuel Cell vehicles are powered by hydrogen, use a completely different propulsion system and can be two to three times more efficient than conventional internal combustion vehicles. Additionally, once the hydrogen is produced, the only emission from the tailpipe water. Still in the development phases, fuel cell vehicles are not available commercially but there are several fuel cell vehicles in fleet applications. And, while this technology has the potential to revolutionize the industry, the deployment is highly dependent on the distribution infrastructure of hydrogen to fuel these vehicles which is also in development.
