Toyota’s third concept for Tokyo will be the FCV-R (Fuel Cell Vehicle – Reality & Revolution), which it says is a practical, family-sized vehicle fuelled by hydrogen. The 4.7 metre-long sedan features seating for four and impressive luggage space, made possible by housing the fuel-cell beneath the specially-designed bodyshell.

Minimal details about it, but Toyota says the fuel cell stack, which includes a 70 MPa high-pressure hydrogen tank, is capable of giving the FCV-R a cruising range of approximately 692 km, measured under a Japanese JC08 test cycle. The company adds it expects to commercially launch a fuel cell vehicle by 2015.
