The EPA certified the 2016 Toyota Mirai hydrogen fuel cell sedan with a 312-mile driving range and 67 miles per gallon equivalent fuel economy both in the city and on the highway. Toyota has been clear for some time that it expected the Mirai to go at least 300 miles, but the Japanese automaker has remained more tight-lipped on the four-door’s hydrogen economy. Our earlier estimate of 60 mpge was low, but in the ballpark.

“Just as the Prius introduced hybrid-electric vehicles to millions of customers nearly 20 years ago, the Mirai is now poised to usher in a new era of efficient, hydrogen transportation,” Toyota North America CEO Jim Lentz said during the EPA figures’ announcement at the Aspen Ideas Festival in Colorado. The company touts the 312-mile range as the longest driving distance of any zero-emissions model currently in the US. It bests the Hyundai Tucson fuel cell’s numbers of around 265 miles and 49-mpge city/50-mpge highway fuel economy. The Mirai also surpasses the 270 miles from the Model S 85D.

Toyota is also going into deeper detail about some of the perks of owning a Mirai. They come with three years or $15,000 of complimentary hydrogen and the company’s Entune system with a refueling station finder. There’s also no-cost scheduled maintenance for the initial three years or 35,000 miles and an eight-year or 100,000-mile warranty on the fuel cell components. The hydrogen sedan goes on sale in California in October for $57,500 before incentives or $499 a month to lease one for 36 months, with $3,649 due at signing. An eventual launch in the Northeast is also planned for later.
