Toyota is one of the major players in the automotive industry working to implement hybrid technology on production cars. It believes the Fuel Cell Hybrid Vehicles offer "the best solution to the challenges of energy sources and emissions, with hydrogen as an ideal, ultra-clean fuel".

They will showing off a more production ready version of the hydrogen powered 2011 FCV-R study at the Tokyo Motor Show this November with actual production model to go on sale in 2015.

We'll also be getting a sneak peak of it at the 2013 Frankfurt Motor Show a week from now saying it "is closing in on its goal of achieving a driving range and performance comparable to conventional petrol and diesel engines, but with no harmful tailpipe emissions".

The concept is 4,745mm long and 1,1510mm high and 1,790mm wide and uses a modified version of the Toyota Prius' Hybrid Synergy Drive system. It uses the same electrical components as well as a 21kW battery to store energy recovered by its regenerative braking system.

The Japanese carmaker stated that it expects "FCHVs to reach full mass-market commercialisation during the 2020s, by when it aims to be selling tens of thousands of vehicles annually".
