6. Toyota FCV Concept
Searching for a solution to the world’s finite fuel problems, Toyota unveiled its FCV concept. The car should be able to travel 500 kilometers (about 310 miles). It uses a pair of high-pressure hydrogen tanks mounted under the car and can carry up to four passengers.
It isn’t the most exciting car to debut in Tokyo this year, but it’s probably one of the clearest previews of what could be a practical shot at green transportation.
