How many miles can you get on a full tank of Toyota Mirai?

Approximately 402 miles per full hydrogen tank on the latest Mirai models, with older generations typically delivering around 312 miles depending on conditions.

The Mirai runs on hydrogen fuel cells that generate electricity to power the electric motor. Range depends on the tank size, the car’s efficiency, climate control use, driving style, and the availability of hydrogen fueling stations in your area.

What affects the Mirai's range

Several factors influence the real-world distance you can cover on a single fill. Here are the main ones:

• Hydrogen tank capacity and fill level (the Mirai uses high-pressure tanks, commonly around 5.6 kg of hydrogen in recent models).


• Vehicle efficiency (how many miles per kilogram of hydrogen the car uses under your typical driving conditions).


• Driving style and speed (steady, moderate speeds maximize range; aggressive acceleration reduces it).


• Ambient temperature and climate-control usage (extreme heat or cold and HVAC demand can lower range).


• Terrain and payload (hills and extra weight consume more hydrogen).


• Hydrogen fueling infrastructure (availability and access can impact the practicality of long trips).

In practice, your actual range will vary with these factors, so the on-road mileage may differ from the EPA sticker.

EPA-estimated range by model year

EPA estimates reflect official testing and have evolved as Toyota updated the Mirai. Here is a simplified guide by generation and era:

• 2016–2019 Mirai: about 312 miles per full tank


• 2021–present Mirai (second generation): about 402 miles per full tank; roughly 74 MPGe combined (EPA)

Note that EPA ranges assume a full, properly filled hydrogen tank and are based on standardized testing conditions. Real-world range can vary with weather, route, and fueling availability.

Maximizing range in everyday use

Owners can take practical steps to get closer to the EPA figure or exceed it under favorable conditions:

• Drive at steady, moderate speeds and minimize rapid acceleration and hard braking.


• Limit use of HVAC systems when possible; precondition the cabin while the vehicle is plugged in or while fueling.


• Keep tires properly inflated to the recommended pressures.


• Choose routes with gentler grades when feasible and plan around charging or fueling stops in advance.


• Keep the vehicle well-maintained (tires, brakes, and powertrain components) to maintain optimal efficiency.

While these tips can help, actual range will still depend on driving conditions and the hydrogen-refueling network available to you.

Summary

The Toyota Mirai typically offers about 400 miles of range on a full hydrogen fill in current models, with earlier generations delivering around 312 miles. Real-world range depends on temperature, driving style, HVAC use, terrain, and access to hydrogen stations. For long trips, planning around an available fueling network is essential.

How far can a Toyota Mirai go on a full tank?

The Toyota Mirai has an EPA-estimated driving range of up to 402 miles on a full tank, though this can vary based on driving habits, weather, and other factors. Real-world driving may result in a shorter range, with some estimates suggesting around 300 miles or less depending on usage, particularly with air conditioning. 
Factors affecting range

• Driving conditions: Highway speeds and aggressive driving can decrease range.
• Weather: Using the climate control system, like air conditioning or heating, will reduce the range.
• Vehicle and road conditions: Factors such as vehicle load and road conditions can also influence fuel efficiency.
• Driving style: Driving in eco mode and maximizing regenerative braking can help achieve a longer range. 

Additional information

• The 402-mile range is an EPA-estimated figure for the XLE trim, which has been standard for several model years. 
• While some drivers have reported achieving lower numbers, the 402-mile estimate represents the most efficient range under ideal conditions. 

Is hydrogen fuel cheaper than gas?

No, hydrogen fuel is currently not cheaper than gasoline, and the cost per mile for hydrogen fuel cell vehicles is significantly higher than for gasoline vehicles. While hydrogen fuel cell vehicles can be more fuel-efficient, the high cost of the fuel itself makes the cost-per-mile higher. 
Current cost comparison

• Hydrogen is more expensive: Current prices for hydrogen fuel are significantly higher than gasoline on a cost-per-mile basis, sometimes three to four and a half times higher. 
• Reasons for higher cost: The higher cost is due to several factors, including the energy-intensive process of producing hydrogen, and the complex and expensive infrastructure needed for storage and distribution. 
• Potential for future changes: Some projections anticipate future cost reductions for hydrogen, particularly green hydrogen, if production and distribution costs fall and infrastructure improves. 

Factors influencing cost

• Fuel efficiency: Hydrogen fuel cell vehicles are more efficient than gasoline engines, meaning a smaller amount of fuel is needed for the same distance. 
• Production method: The method used to produce hydrogen impacts its cost. 
  • Green hydrogen: (produced from renewable energy) is currently expensive but is expected to become cheaper. 
  • Gray hydrogen: (produced from natural gas) is cheaper to produce but relies on fossil fuels. 
• Incentives: Some areas, like California, offer subsidies that can lower the retail price of hydrogen fuel. 

What this means for drivers

• Higher per-mile costs: For a consumer in 2025, the cost of fueling a hydrogen vehicle is higher than a gasoline vehicle. 
• Potential long-term savings: If the cost of hydrogen fuel decreases significantly in the future, the cost per mile could become more competitive, especially when combined with the higher efficiency of the vehicles. 

How many miles can a Toyota Mirai last?

The Toyota Mirai's fuel cell system is designed to last the lifetime of the vehicle, which is estimated to be around 150,000–200,000 miles. While individual component lifespan is often measured in these terms, the car's overall expected mileage can be influenced by factors like driving habits, weather, and maintenance, though Toyota designs the Mirai's core fuel cell technology for long-term durability.
 
Fuel cell lifespan

• The fuel cell stacks are designed to last the lifetime of the vehicle, approximately 150,000–200,000 miles, before they are disassembled for recycling.
• Toyota designs the fuel cell system with durability in mind, meaning it should operate for the expected lifespan of the car. 

What affects mileage

• The overall expected mileage of a Mirai can vary depending on driving conditions, much like any other vehicle.
• Factors that can affect mileage include driving behavior, weather, use of the air conditioning, and vehicle maintenance. 

Other considerations

• The Mirai has a basic warranty of 3 years or 36,000 miles, and Toyota provides a separate warranty for the fuel cell components, which is much longer. 
• The expected lifespan is based on the durability of the fuel cell system, which is a core component of the vehicle. 

How much does it cost to fill up Mirai?

Filling up a Toyota Mirai can cost approximately $175 to $202, depending on the current hydrogen fuel price, which can be volatile. For example, a price of $36$ 36$36 per kilogram, combined with the Mirai's 5.6 kg tank, equals $201.60$ 201.60$201.60. The cost is significantly higher than it used to be and much higher than for a comparable electric vehicle. 

• Current cost: A full tank can cost around $201.60$ 201.60$201.60 if hydrogen is priced at $36$ 36$36 per kilogram. 
• Price per kilogram: Recent prices have been reported to be around $36$ 36$36 per kilogram, a significant increase from earlier prices. 
• Comparison to electric vehicles: It is reportedly 14 times more expensive to operate a hydrogen car like the Mirai compared to a comparable electric vehicle in California. 
• Free fuel incentives: Many new Mirai purchases include a substantial fuel credit, often around $15,000$ 15 comma 000$15,000 worth of free hydrogen fuel, which can cover the cost for several years.
