Which Toyota model is a hydrogen fuel-cell sedan first sold in 2014?

The Toyota model that is a hydrogen fuel-cell sedan first sold in 2014 is the Toyota Mirai. Its name comes from the Japanese word for “future,” reflecting Toyota’s effort to develop cars powered by hydrogen rather than gasoline or diesel.

Toyota unveiled the production-oriented Mirai in 2014 and began production in December of that year. It became one of the first hydrogen fuel-cell vehicles to be mass-produced and sold commercially. The car generates electricity in a fuel-cell stack by combining hydrogen with oxygen, using the electricity to power an electric motor.

Unlike a conventional internal-combustion car, the Mirai produces no tailpipe carbon dioxide during operation. Its main emission is water, although the overall environmental benefit depends on how the hydrogen is produced. Refueling can take only a few minutes, but the car’s practicality depends heavily on access to hydrogen stations.

The Mirai is sometimes confused with a battery-electric Toyota such as the Prius, but the two use different energy systems. The Avalon and Cressida are gasoline-powered Toyota sedans, while the Supra is a performance-focused sports car rather than a fuel-cell vehicle.
