YOUR NEXT CAR WILL BE A VOLT:

What strikes you first when driving a hydrogen vehicle is the quiet and the acceleration -- it puts out lots of torque. These cars also have far fewer moving parts than other cars -- no engine, fancy transmission, or drivetrain -- so it will be much simpler and cheaper to maintain. The retrofitted Highlander I drove can travel 300 miles on a tank of hydrogen and takes less than four minutes to fill. The production version of Toyota's new hydrogen car will be unveiled at the Tokyo auto show in November.
