Recently, at the Aspen Ideas Festival in Aspen, Colorado, Toyota North America CEO Jim Lentz announced that the Mirai is capable of an EPA-estimated 67 miles per gallon equivalent (mpge) city/highway/combined. That roughly translates to a 4.2 litres per 100 km equivalent, giving the Mirai an estimated driving range of 502 km.
Imagine that, 502 km on a single fill of hydrogen which takes about three minutes to do, similar to a conventional petrol powered car. The four-door, mid-size sedan Mirai is capable of generating electricity on demand using just hydrogen, oxygen, and a fuel cell, with the only emission being water vapour. Looks like hydrogen could very well be the fuel of the future.
