Toyota Mirai units 845-mile hydrogen mileage report


Battery electrical autos are at present the belle of the inexperienced automotive ball, however Toyota’s hydrogen-powered Mirai makes a compelling case for maintaining an invitation to the occasion open for gas cell EVs. As an example, Toyota has laid declare to the Guinness World Document for the longest distance traveled by a gas cell automobile with out refueling, finishing an 845-mile journey round Southern California.

The record-making try came about over two days on Aug. 23 and 24 this yr with skilled hypermiler Wayne Gerdes behind the wheel and Bob Winger as his co-pilot. After a 5-minute fill-up, the 2021 Mirai’s tank was sealed and authorized by Guinness World Information officers earlier than the crew departed the Toyota Technical Middle in Gardena, California. The Mirai traveled to San Ysidro, then Santa Barbara, then continued alongside the Pacific Coast Freeway by Santa Monica and Malibu earlier than returning to Gardena. The crew arrived again at TTC with 473 miles logged by GPS. 

Guinness World Information official licensed that the Mirai’s H2 tank remained sealed in the beginning and finish of the report try.


On Day 2, the crew resumed their driving, logging 372 extra miles on a neighborhood loop earlier than coasting again to TTC with a grand whole of 845 miles pushed. Guinness officers then confirmed that the FCEV’s tank seal had not been tampered with and commenced the method of certifying the report try. 

Toyota tells us that the Mirai averaged 152 miles per gallon equal and consumed a complete of 5.65 kilograms of hydrogen over the 2 days of testing. with its solely tailpipe emission being water. The automaker estimates {that a} combustion-powered sedan would have emitted about 664 kilos of CO2 over the identical distance. I pulled up the EPA’s numbers to do the maths myself and it roughly checks out: A equally sized Toyota Avalon V6 would have exhausted round 352 grams per mile, totaling 658 kilos of CO2 for the overall distance.

The record-holding automobile was unmodified; Toyota attributes its extended-range efficiency to a mix of correct upkeep and wheel alignment, fine-tuned tire stress and hypermiling driving methods.

“In 2016, the Toyota Mirai was the primary manufacturing gas cell electrical automobile obtainable for retail sale in North America, and now the next-generation Mirai is setting distance information,” stated Bob Carter, govt vp of Toyota Motor North America. “We’re proud to be leaders of this thrilling know-how, which is only one of a rising lineup of zero-emission autos in our portfolio.”
