The futuristic van focuses on a plush rider experience, with rotating seats to promote interaction between all occupants when the car is driving itself.

Toyota has previewed a bold vision for a luxurious fuel-cell vehicle, the Fine-Comfort Ride concept.Billed as "a new form of the premium saloon," the concept is arguably a closer fit to current minivans. In any case, the cabin is large enough to fit four plush captain's chairs that can rotate inward for enhanced interaction between passengers when the car is driving itself.

The van's exterior is distinguished by its aerodynamic features around the wheels, each driven by an in-wheel motor and positioned to the far corners. Toyota says the design maximizes efficiency and helps achieve better stability and quietness.

A hydrogen fuel-cell powertrain is said to be capable of driving for up to 621 miles (JC08 test cycle) between fill-ups, potentially alleviating the current problems FCV owners face with just a few hundred miles of range and sparsely located filling stations.

The Fine-Comfort Ride will be on display next week at the Tokyo Motor Show.
