The Mirai uses the Toyota Fuel Cell System (TFCS), which features both fuel cell technology and hybrid technology, and includes Toyota’s new proprietary FC Stack and high-pressure hydrogen tanks. The TFCS is more energy efficient than internal combustion engines and emits no CO2 or pollutants when driven. Drivers can also expect the same level of convenience as offered by gasoline engine vehicles, with a generous cruising range and a hydrogen refuelling time of about three minutes.
