Most major automakers produce and sell AFVs—cars, light- and heavy-duty trucks, shuttle buses, transit buses, off- road vehicles, and even boats. Many AFVs are sold as fleet vehicles, but some are now available to the public. In fact, you may already be driving around in an alternative fuel-capable vehicle and not even know it. Look in your owner’s manual or on the inside of the fuel compartment door for information on what fuels are appropriate for your vehicle.
There are three basic types of AFVs: flex-fuel, bifuel or dual-fuel, and dedicated vehicles.
A flex-fuel vehicle (FFV) has one tank and can accept any mixture of gasoline and either methanol or ethanol. P-Series fuel is designed to run in FFVs also.
It’s estimated that 1 to 2 million FFVs are already on American roads.
Bifuel vehicles have two tanks— one for gasoline and one for either natural gas or propane, depending on the vehicle. The vehicles can switch between the two fuels.
Dedicated vehicles are designed to be fueled only by an alternative fuel.
EVs are a special type of dedicated vehicle. EVs—like small cars and bicycles—are perfect for driving short distances and where low top speeds aren’t an issue, such as in small neighborhoods. Some EVs today though can break most highway speeds. Some large shuttle buses are also EVs.
