Toyota Mirai drives 845 miles on a tank of hydrogen, sets world record

A Toyota Mirai has set an official Guinness World Record for the longest distance by a hydrogen fuel cell electric vehicle without refuelling. The 2021 Mirai achieved 845 miles on a single tank. Those with weak bladders, look away now.

‘Professional hypermiler’ Wayne Gerdes undertook the two-day odyssey alongside co-pilot Bob Winger on 23-24 August over in the States. And to be clear, this was an actual, official attempt, not just striking it lucky while popping out for a loaf of bread and some milk.

Beginning at the Toyota Technical Center in Gardena, California on Monday, Wayne and Bob drove 473 miles in a single day – taking in Santa Barbera, Malibu beach, the PCH – after just two driver swaps.

The next day the pair covered a further 372 miles of eco-infused driving, taking in some rush hour traffic for good measure. Guinness adjudicator Michael Empric validated the 845-mile total as they coasted back into Gardena.

Toyota tells us the Mirai ate through 5.65kg of hydrogen over those two days, but there’s no word on what Wayne and Bob ate. Indeed, they passed 12 hydrogen filling stations without stopping – that’s 12 missed opportunities to get service station sandwiches and crisps. Truly, these two deserve medals of honor.

As a kid, we'd sometimes have a slow race. Whoever got to the finish last without actually stopping was the winner.

I feel like that's what these "accomplishments" are. More of a test of patience than of technology.

Mirai elucidations

I went to Toyota's official Mirai site and found it useless as far as technical specifications for the car.

Pffft . . .

I got 700+ mile tanks in my twenty year old G1 Insights in daily driving in traffic

Before I became too lazy to record my daily data I was getting 150+ mpge in my G2 Volt and had the estimated EV range up to almost 80 miles, also while driving real world traffic back and forth to work

Yea, I like Horst Lünings record attempts more.
Getting >2600 km out of a Tesla on normal roads in 24h shows the capabilities better than crawling for 2 days.

wow, those things must be all over the place!

845 miles

Just enough to get to the closest fueling station and home again! :D

I think that's pretty cool, even if there are 0 hydrogen stations and hydrogen vehicles where I live.

(I'm not trying to start a political debate, just mention a hypothetical situation. If you don't like hypothetical situations, please stop reading this immediately.) If a government were to impose a no-ICE or no-fossil fuel law in the future then long range drivers would be severely handycapped by BEV technology. Hydrogen could fill that gap for those that need to go long distances but can't or don't want to use ICE technology and that don't want to wait for the frequent and long charge times of BEV's.

Hydrogen fuel cells are about 50% efficient.

Might as well simply burn the natural gas directly than to do a bunch of energy conversions.
