How many miles can a Mirai go?
The Mirai typically covers about 400 miles on a full hydrogen fill, with EPA estimates for recent generations around 402 miles. Real-world mileage varies based on model year, driving conditions, and fueling habits.
Hydrogen fuel-cell vehicles like the Mirai convert stored hydrogen into electricity to power the electric motor. Over successive generations, Toyota has boosted range by refining tank capacity and the fuel-cell system, while real-world range continues to depend on where and how you drive and how easily hydrogen is available for refueling. The following overview explains the evolution of the Mirai’s range and the factors that influence what you’ll actually experience.
Historical range by generation
EPA range figures reflect official ratings and can vary by trim and market. The numbers below summarize the broad range trend between the Mirai’s generations in the U.S. market.
- 2016–2019 Mirai: EPA-estimated range of about 312 miles (502 km)
- 2021–present Mirai: EPA-estimated range around 402 miles (647 km)
Note that the 2021 redesign introduced a higher-capacity hydrogen tank and a redesigned fuel-cell stack, which enabled the notable jump in range. Actual mileage can vary with weather conditions, driving style, and climate-control use.
Factors that affect real-world range
When planning trips, drivers should consider these elements that commonly alter the Mirai’s practical mileage beyond the official EPA rating.
- Driving style and speed: rapid acceleration and sustained high speeds reduce efficiency.
- Climate control usage: heating in cold weather and air conditioning in hot weather consume more energy.
- Terrain and traffic: hilly routes and stop-and-go traffic increase energy use.
- Hydrogen availability and refueling: station density and refueling time affect trip planning.
- Vehicle maintenance and tires: underinflated tires or poor maintenance lower efficiency.
With careful planning and moderate driving habits, most Mirai owners can approach the advertised range on longer trips, provided hydrogen is accessible along the route.
Summary
In brief, the latest-generation Mirai typically delivers about 400 miles of range per hydrogen fill, with EPA estimates around 402 miles. The older generation offered roughly 312 miles. Real-world mileage depends on driving conditions, climate, and refueling infrastructure, so travelers should plan accordingly and verify current specifications for their exact model year and trim.
