Toyota Mirai sets Guinness World Record for longest hydrogen car single-tank journey- 1,359km, 2.2l/100km

A new Guinness World Record has been set by the Toyota Mirai for “the longest distance by a hydrogen fuel cell electric vehicle without refueling”.

Over the course of two days (761 km on first day, 598.7 km on second day), a total of 1,359 km was covered by the Toyota Mirai, consuming a total of 5.6 kg of hydrogen.

The average speed of the journey was not mentioned, but Toyota does state that the Mirai was mainly driven during rush hour traffic in temperatures between 18°C and 28°C.

Emitting only water, an equivalent ICE car would have produced 301 kg of CO2 over the same distance.

Using 5.6 kg of hydrogen for the 1,359 km distance, the miles per gallon of gasoline equivalent (MPGe) is calculated at 152 MPGe.

On its efficiency-focused August 23 and 24, 2021 journey, the Mirai logged an impressive 152 MPGe with water as its only emission or 2.2l/100km (gasoline equivalent).

MPGe is calculated by basing the energy consumption on the energy density of gasoline.

The record was accomplished with the help of hypermiling expert, Wayne Gerdes and co-piloted by Bob Winger.

As for gasoline cars, the Guinness World Record for “greatest distance driven on a single standard tank of fuel is” 2,545.80 km (1,581.88 miles) by a Volkswagen Passat 1.6 TDI BlueMotion (3.08 l/100km).

As for BEVs, Tesla has reported that the Tesla Model S 100 D covered 1,078 km on a single charge during a 27-hour marathon with a 40-km/h average speed.
