Of the concepts shown, the FT-EV III (Future Toyota Electric Vehicle III) is the closest to production. Based on the iQ, it’s a lightweight four-seat city car offering a range of 65 miles from a full battery charge, and previews a short-distance electric vehicle due next year.

Looking further ahead, Toyota is planning to launch its first hydrogen fuel cell vehicle in 2015. The FCV-R (Fuel Cell Vehicle – Reality and Revolution) concept is roughly the same size as an Avensis, with space for four passengers and a large luggage space. Its high-pressure hydrogen fuel tank gives a range of 430 miles with zero CO2 emissions.

The final concept, named Fun-Vii (Fun-Vehicle interactive internet) is further from production, but previews Toyota’s connected technology which, the manufacturer said, links “people, cars and society.”

Alongside the concept vehicles, the Tokyo Motor Show marks the Japanese premiere of the Prius Plug-In Hybrid and compact Aqua hybrid, which launches in Japan in December before being rolled out worldwide. Toyota’s compact sports car, developed with Subaru, will also be unveiled in production-ready form at the show.
