For the Tokyo-bound concept, Toyota has placed a fuel cell stack between its front wheels. This generates electricity by combining oxygen drawn from the atmosphere with hydrogen stored in a tank behind the rear seats.
The electricity can be used to power compact in-wheel electric motors located in each of the car's four wheels.
When the car isn't being driven, the fuel cell stack can be used as a power source with hydrogen supplied from either the car's on-board tank or an external source.
With a layout that concentrates the largest drivetrain components at the front and rear of the car, Toyota claims that the FCV Plus has ample interior space, while the interior's frame structure allows for light weight and high rigidity.
As with the other concept car debutants on the Toyota's Tokyo stage this year, the S-FR coupe and Kikai hot rod, the FCV Plus will have no problems winding and wending its way through the country's narrow streets.
The FCV Plus measures 3.8 metres long, is 1.75m wide, stands 1.54m tall and rides on a three metre wheelbase.
Unlike the controversially styled Mirai sedan, there's no suggestion the the FCV Plus will go into production.
