How many miles per gallon does a Toyota Mirai get?
Around 74 miles per gallon equivalent (MPGe) combined. The Mirai uses hydrogen fuel cells, so its efficiency is reported as MPGe rather than conventional MPG.
In practice, EPA numbers break down into city and highway estimates, and recent model years may show small variations due to tires, trim, and updates. For the current generation introduced in 2021, the Mirai is typically rated around 74 MPGe combined, with city results in the mid-to-high 60s and highway results in the low-to-mid 70s.
EPA MPGe ratings for the current Mirai
The following figures reflect EPA estimates for the current generation of Mirai. They serve as a baseline for comparing efficiency with other vehicles and estimating range per fill.
- Combined MPGe: about 74 MPGe.
- City MPGe: typically around 66–68 MPGe.
- Highway MPGe: typically around 72–75 MPGe.
- Estimated driving range on a full hydrogen fill: about 380–400+ miles, depending on model year and conditions.
These numbers provide a baseline for comparing the Mirai’s efficiency with gasoline-powered cars and other EVs. Real-world results vary with driving style and fueling availability.
Real-world considerations and how to maximize efficiency
In practice, your MPGe will depend on driving habits, climate control usage, and access to hydrogen fueling. Hydrogen infrastructure varies by region, which can affect real-world performance and range planning.
Tips to optimize MPGe
Lead with smooth acceleration, anticipate stops to maximize regenerative braking, keep tires properly inflated, and plan trips to align with hydrogen station availability to minimize energy losses and optimize overall efficiency.
Summary: The Toyota Mirai typically posts about 74 MPGe combined in recent models, with city MPGe in the mid-60s and highway MPGe in the low-to-mid 70s. Real-world results depend on driving conditions and fueling access, and the car delivers an approximate 380–400+ mile range per hydrogen fill.
