The Mirai is a hydrogen fuel cell sedan that produces zero emissions and refuels in minutes, but ownership depends entirely on whether hydrogen stations exist near you
The Toyota Mirai is a four-door sedan powered by hydrogen gas instead of petrol or a rechargeable battery. It converts hydrogen into electricity through a fuel cell stack, with water vapour as the only tailpipe emission. The car accelerates smoothly, drives up to 300 miles on a full tank, and refuels in about five minutes—much faster than charging a battery electric vehicle.
The catch is infrastructure. Hydrogen stations are sparse in most of North America. California has the largest network with roughly 50 public stations, mostly in the San Francisco Bay Area and Los Angeles County. Outside California, hydrogen stations are scattered across a handful of cities in the Northeast and Midwest. If there is no station within reasonable distance of your home and regular driving routes, the Mirai is not practical for you, regardless of how well the car itself performs.
Key Takeaways
- The Mirai refuels with hydrogen gas in about five minutes and produces only water vapour as emissions, making it genuinely zero-emission at the point of use.
- Driving range is 300 to 370 miles per tank depending on the model year, which is comparable to a petrol sedan and longer than most battery electric vehicles.
- Hydrogen station availability is the limiting factor—California has the most stations, but most other states have few or none, making the car impractical outside specific regions.
- Lease programs exist in California and a few other states, but purchasing a Mirai outside these regions is difficult because resale value depends on local hydrogen infrastructure.
- The fuel cell stack is covered by Toyota's warranty for eight years or 100,000 miles, and hydrogen fuel is not taxed the way petrol is in most states.
How the Mirai's hydrogen fuel cell actually works
The Mirai stores hydrogen gas in a high-pressure tank (typically 5,000 psi) mounted under the rear seat. When you drive, hydrogen flows from the tank into the fuel cell stack, a device that sits where a petrol engine would. Inside the stack, hydrogen gas meets oxygen from the air. A chemical reaction between them produces electricity, which powers an electric motor. The only byproduct is water, which exits as vapour through the tailpipe.
This is different from a battery electric vehicle, which stores energy in a large rechargeable battery pack. The Mirai generates electricity on demand as you drive, so there is no long charging time and no battery degradation over years of use. The fuel cell stack itself is designed to last the life of the vehicle, though Toyota warrants it for eight years or 100,000 miles—whichever comes first.
The electric motor in the Mirai is nearly silent and delivers power when ready, much like any battery electric car. Acceleration is smooth and responsive. The car handles like a conventional sedan, and the driving experience is unremarkable in the best way—it straightforward works without the noise or vibration of a petrol engine.
Hydrogen station networks and where you can actually refuel
California dominates hydrogen infrastructure in North America. The state has roughly 50 public hydrogen stations, with the densest clusters in the San Francisco Bay Area, Los Angeles, and San Diego County. Most stations are operated by Shell, Air Liquide, or Iwatani, and many are located near major highways or in urban centres. If you live in one of these regions and drive regularly within California, refuelling is straightforward.
Outside California, hydrogen stations are rare. Massachusetts, Connecticut, New York, and a few Midwest states have a handful of stations each, usually concentrated in or near major cities. If you live in Texas, Florida, the Pacific Northwest, or most of the South, there are effectively no public hydrogen stations. Before considering a Mirai, check the HydrogenStations.com map or the Department of Energy's Alternative Fuels Data Center to see what exists within your region. If the nearest station is more than 30 miles away, the car becomes impractical for daily use.
Some Mirai owners in California with access to stations report that refuelling is faster and more convenient than charging a battery electric vehicle, and that hydrogen availability is improving. Owners outside California or in rural areas report that the car is essentially unusable for anything beyond short trips to a distant station.
Lease versus purchase: which makes sense for a Mirai
Toyota offers the Mirai primarily through lease programs in California and a limited number of other states. A typical lease runs three years and includes maintenance, roadside information, and a fuel card that covers hydrogen refuelling at participating stations. Monthly payments vary but are often comparable to leasing a mid-range battery electric vehicle. Leasing removes the risk of owning a car whose resale value depends on hydrogen infrastructure that may not exist in your area.
Purchasing a Mirai outright is possible but risky outside California. The used market is tiny, and resale value is unpredictable because it depends entirely on whether hydrogen stations exist where the next owner lives. A Mirai that is worth $25,000 in the San Francisco Bay Area might be worth $5,000 in a state with no hydrogen infrastructure. Toyota does not publish purchase prices or financing terms as prominently as lease offers, which signals that the company sees leasing as the intended path for most buyers.
If you live in California with reliable access to hydrogen stations and want to try fuel cell technology without long-term commitment, leasing is the sensible choice. If you live outside California, leasing may not be available to you at all, which effectively means the Mirai is not an option.
Fuel cost, maintenance, and warranty coverage
Hydrogen fuel cost varies by station and region but typically ranges from $12 to $18 per kilogram in California. A Mirai uses roughly 0.95 kilograms per 100 miles, so a 300-mile tank costs approximately $34 to $51 to fill. This is comparable to or slightly higher than petrol in many regions, though hydrogen is not subject to federal fuel tax in most states, which can make it cheaper than the pump price suggests.
Maintenance on a Mirai is minimal because the fuel cell stack has no moving parts and the electric motor requires no oil changes, spark plugs, or transmission fluid. Toyota covers the fuel cell stack, battery, and related components for eight years or 100,000 miles. Brake pads last longer than in petrol cars because the Mirai uses regenerative braking (the electric motor slows the car and recaptures energy). Scheduled maintenance is limited to cabin air filter replacement and occasional fluid checks.
The warranty is a significant advantage. If the fuel cell stack fails within eight years or 100,000 miles, Toyota replaces it at no cost. This protects against the one major component that could be expensive to repair. After the warranty expires, repair costs for fuel cell components are unknown because so few Mirais are on the road and so few have aged beyond the warranty period.
Real-world driving range and refuelling time
The Mirai's EPA-estimated range is 300 to 370 miles per tank, depending on the model year and driving conditions. Newer models (2021 and later) achieve the higher end of that range. This is comparable to a mid-size petrol sedan and longer than most battery electric vehicles, which typically range from 200 to 300 miles per charge.
Refuelling takes about five minutes from empty to full, similar to filling a petrol tank. You pull up to a hydrogen pump, insert the nozzle into the filler port, and wait. There is no need to plug in, wait for a charge cycle, or plan around charging station availability—as long as a station exists near you. This speed and simplicity are genuine advantages over battery electric vehicles, which require 20 minutes to several hours to recharge depending on the charger type.
In practice, Mirai owners in California report that the combination of long range and quick refuelling makes the car feel like a conventional petrol sedan in terms of convenience. Owners outside California report that the lack of nearby stations makes the car feel like a novelty that cannot be used for normal driving.
Environmental impact and hydrogen production
The Mirai produces zero tailpipe emissions—only water vapour exits the exhaust. However, the environmental benefit of hydrogen depends on how the hydrogen was produced. Most hydrogen in North America is made from natural gas through a process called steam methane reforming, which produces carbon dioxide as a byproduct. Some hydrogen is produced by electrolysis (splitting water using electricity), which is cleaner if the electricity comes from renewable sources like wind or solar.
California has invested in hydrogen production infrastructure and incentivizes cleaner production methods, so hydrogen at California stations is increasingly produced with lower carbon intensity. Outside California, hydrogen production methods are less regulated and less transparent. A Mirai fuelled with hydrogen from natural gas is cleaner than a petrol car at the tailpipe, but its overall environmental benefit compared to a battery electric vehicle charged from the grid depends on the electricity mix in your region and the hydrogen production method used at your local station.
If environmental impact is your primary concern, research the hydrogen production methods used at stations in your area. In California, this information is often available from the station operator or the state's hydrogen fuel cell program. Outside California, it may be difficult to find.
Frequently Asked Questions
Can I buy a Mirai if I don't live in California?
Toyota leases the Mirai in California, Massachusetts, Connecticut, and a few other states, but availability varies. Purchase options outside California are extremely limited because resale value is unpredictable without hydrogen infrastructure. Check with a Toyota dealer in your state to see whether leasing is available and whether hydrogen stations exist near you.
What happens if I run out of hydrogen while driving?
The Mirai has a fuel gauge and range display, similar to a petrol car. If you are low on fuel, the car alerts you to find a station. Running completely empty is unlikely if you monitor the gauge, but if it happens, you cannot coast to a station or call for a fuel delivery the way you might with petrol. Plan your route around known hydrogen stations before you drive.
Is hydrogen fuel safe to store in my car?
Yes. The hydrogen tank is made of carbon fibre composite and is designed to withstand high pressure safely. It is tested to the same safety standards as petrol tanks. Hydrogen is lighter than air and disperses quickly if there is a leak, unlike petrol vapour, which is heavier and can accumulate. Crash test data for the Mirai shows no safety issues related to the hydrogen system.
How does a Mirai compare to a battery electric vehicle in total cost?
Lease payments are often similar, but total cost depends on fuel price, electricity cost in your region, and maintenance. Hydrogen fuel typically costs $12 to $18 per kilogram in California, while electricity for a battery electric vehicle costs roughly $3 to $6 per 100 miles depending on local rates. If hydrogen is cheaper in your area, the Mirai may cost less to operate. Outside California, hydrogen availability makes the comparison moot.
Will hydrogen stations become more common in the future?
California continues to invest in hydrogen infrastructure, and a few other states have announced plans to expand stations. However, growth is slow compared to battery electric vehicle charging networks. If you need a car now and hydrogen stations do not exist near you, betting on future infrastructure is risky. Make your decision based on what exists today, not what might exist in five years.
