The Mirai is the first hydrogen-powered fuel-cell vehicle available for consumers to own.
It has a range of almost 275 miles on a single fill-up of 5 kg of hydrogen (the energy equivalent of 5 gallons of gasoline).
It takes only a few minutes to fill the tank, as opposed to hours of charging an electric car.
The Mirai is sold only in areas near existing hydrogen fueling stations in California, but even so, these stations are few and far between.
Acceleration from the 153-hp electric motor feels sluggish, but otherwise it is like driving any other electric car.
It's about the size of a Camry and seats four people.
Handling is rather clumsy but still feels secure; the ride is comfortable, and the cabin is quiet.
Toyota is offering free fuel for three years, capped at $15,000 in value.
