The Mirai offers something unique in the marketplace to get the best of all worlds between hybrids and pure electric vehicles. While hybrids are easy to refuel, they still pollute when they burn gasoline. And while electric vehicles do away with this pollution, they are time consuming to refuel - often taking several hours. The Mirai, on the other hand, takes about five minutes to refuel and the hydrogen drivetrain's only waste product is water vapor.
