Toyota released a data sheet on its high-tech exhibits at the upcoming Tokyo Motor Show, which include the Fine-X. This experimental vehicle uses a fuel-cell system for power and four independent hub-attached electric motors. All the wheels turn, letting the vehicle maneuver in extremely tight spaces. It has seats that adjust to let drivers and passengers exit or enter more easily, as well as gull-wing doors. Toyota will also be showing off its bB concept, tagged by Toyota as "a music player in the shape of a car that can function as a local hangout for young people." The bB is widely thought to be the basis for the next-generation Scion xB. I'll take a close look at these concepts next week, where I'll be reporting back from the auto show on Thursday.
