The new Toyota Mirai hydrogen fuel cell vehicle has proved it can go the distance, traveling over 300 miles on a single tank.
Instead of using petrol however, the car runs on electricity created on demand by hydrogen fuel and oxygen. The only emission produced by this process is water vapour.
The Mirai achieved 67 mpg in official US combined city/highway driving calculations, and an estimated driving range of 312 miles on a one tank - a distance Toyota says is further than for any other zero-emissions car on the market.
Jim Lentz, Toyota North America CEO, announced the Environmental Protection Agency's (EPA) fuel economy rating for Mirai at the Aspen Ideas Festival in Colorado. It confirmed that the Mirai is the only zero emissions electric vehicle on the market capable of exceeding 300 miles on one fill.
Lenz said: "Toyota realised in the early 90s that electrification was key to the future of the automobile. Just as Prius introduced hybrid-electric vehicles to millions of customers nearly 20 years ago, Mirai is now poised to usher in a new era of efficient, hydrogen transportation."
The Japanese manufacturer describes the Mirai is the world's first mass-produced hydrogen fuel cell electric vehicle, a four-door saloon with performance that competes with traditional internal combustion engines. Toyota will introduce the Mirai in limited numbers in the UK and other selected European markets later this year, following its launch in Japan and, from this summer, California.
