The FCV Plus previews Toyota's vision of the future of the car, using compressed hydrogen as its fuel source. When the car isn't in use for transport, it can be used as a generator to make electricity for the driver's home; it can also be used away from the home, and when not in use, it puts energy back into the grid.
The car's overriding ethos, according to Toyota, is "how future hydrogen cars can make a positive contribution to society".
There's a motor for each wheel on the FCV Plus, with the fuel cell stack between the front wheels and the hydrogen tank between the back wheels. Toyota says the car won't reach production for at least 15 years. By the time the FCV Plus does reach production, Toyota expects the hydrogen powertrain to be around half the size of that currently used in the Mirai FCV.
