Propane is an approved alternative fuel listed in the Clean Air Act Amendments of 1990 and the Energy Policy Act of 1992. The range of propane vehicles is almost equal to that of comparable gasoline vehicles. The power, acceleration, payload and cruise speed of propane vehicles are comparable to that of equivalent internal combustion engines. Propane vehicle users report longer engine life and low maintenance costs. The tanks are 20 times more puncture resistant than gasoline tanks.
Propane has a low flammability range.
Automakers continue to manufacture a number of factory-equipped propane vehicles. Part of the cost may be deducted from federal taxable income. The cost of building propane fueling stations is similar to, or lower than, comparable sized gasoline dispensing systems.
