Dual fuel vehicles are designed to run on two fuels - where the driver can alternate using the flick of a switch. The most common duel fuel vehicle currently in use runs on regular gasoline and natural gas. However, there are those that run on gas and methanol or ethanol as well, and experiements are being done on many other fuels like liquid nitrogen.
There are several reasons for "dual fuel" vehicles: First, they provide a bridge to true alternative fuel cars because the infrastructure for alternative fueling is not in place. In other words, it may be better to run on natural gas, but if you run out of natural gas and are away from home, it may be hard to find a natural gas filling station! However, even if there was an infrastructure, dual fuel vehicles would still be important if a vehicle runs differently on the two different fuels - e.g. if natural gas was more efficient for city driving, but tradational gas was better for higher speeds on the highway. In addition, dual fuel vehicles allow the driver to choose the fuel that is cheaper at that time.
