Announcing the FCV Toyota Mirai

The Toyota Mirai features the unique Toyota Fuel Cell System, which combines fuel cell technology with hybrid technology.
The system is more energy efficient than internal combustion engines, and offers excellent environmental performance without emitting CO2 or other harmful substances during driving. At the same time, the system gives vehicles convenience on a par with conventional gasoline engine vehicles, thanks to a cruising range of roughly 300 miles and a refueling time of about three minutes.
