TORRANCE, Calif. - Honda's fuel cell-powered FCX is quick off the line.
One reason: It is equipped with an ultracapacitor that stores electrical power for those occasions when bursts of energy are needed.
American Honda Motor Co. is not recommending the stodgy-looking compact as a drag racer. But the automaker is trying to prove that fuel cell-powered vehicles are capable of satisfying real-world performance. For most people, that includes getting away from a traffic light with vigor.
Although automakers usually don't say much about proprietary features of experimental or future vehicles, Honda officials have been quite open about their ultracapacitor. Most other automakers rely on batteries for electrical storage on their fuel cell vehicles.
