If all the alternative-fuel vehicles at the Detroit auto show make it to the showroom, your local filling station could become the automotive equivalent of a soda fountain. There could be many flavors of fuel on tap.
The usual three grades of gasoline would be joined by:
Honda showed the next generation of its FCX fuel cell vehicle, which uses gaseous hydrogen to generate electricity. Honda will start producing the swoopy car by the end of the decade.
Ford's Super Chief concept truck is the king of flexible fueling. It can run on three fuels: gasoline, E85 or hydrogen.
A few of the powertrains in the concepts already have been produced: for example, Honda's compressed natural gas Civics; early versions of Honda's FCX; and General Motors' gasoline-E85 engines used in trucks.
