Bi-fuel vehicles are unique in that they can run on more than one fuel, and may seamlessly switch between them, like Alliance’s gasoline and propane autogas technology. The Prins system has been used for years in Europe, and bi-fuel technology has already been proven with propane autogas and natural gas vehicles in other countries.

Light- and medium-duty vehicles running on autogas typically achieve 85-90 percent of the miles per gallon they would on gasoline, while CNG vehicles might have around 60 percent of a gasoline vehicle’s range. This is due to the very high pressure involved in storing natural gas (see: Autogas for America’s white paper). Since autogas fleets are currently experiencing cost savings of $1.25 or more per gallon while not using up all their payload capacity with heavy storage tanks like natural gas vehicles have, it’s a win-win situation all around.
