What you're looking at is the concept version of a future production car that may turn out to be something of a game changer. Yesterday, Toyota revealed its 300-mile range hydrogen fuel cell Mirai, a car that'll go on sale in the US in 2016. Today it's Honda's turn. Presenting the Honda FCV Concept, a vehicle scheduled to go on sale in Japan by the end of March 2016 and subsequently in the US and Europe. Consider the FCV Concept as the successor to the FC Clarity.

Honda claims the FCV will be the world's first fuel cell vehicle sedan with the entire powertrain, including the downsized fuel-cell stack, consolidated under the hood, thus enabling a full cabin package that seats five adults comfortably. What's more, this architecture can be evolved into multiple models in the future. The FCV Concept is equipped with a 70 MPa high-pressure hydrogen storage tank that provides a cruising range of more than 435 miles. The tank itself can be refilled in about three minutes. Yes, that's about how long it typically takes to refuel any gasoline and or diesel-powered vehicle. The fast refuel timing is not a coincidence.

In addition, there's also an external power feeding function which, when combined with an external power feeding device, allows the vehicle to function as a small-sized mobile powerplant that generates and even provides electricity in an emergency or disaster situation. Yep, it's literally a miniature power station on four wheels.
