Fuel economy at a glance
These are the EPA's official ratings for the 2019 Toyota Mirai. The numbers come from a standardised laboratory test cycle and are the same figures that appear on the window sticker of every new car. Real-world mileage varies with driving style, weather, fuel quality, and how heavily loaded the car is.
Combined MPG is a 55/45 weighted blend of the city and highway test cycles. The EPA uses it as the single number you can compare across the entire dataset, including hybrids and EVs (which use the equivalent MPGe figure).

How the 2019 Toyota Mirai compares
The 2019 Toyota Mirai returns 67 combined MPG. Cars in the Subcompact Cars class for the same model year average 26.1 MPG, which puts this car ahead of the class average by about 157%.
The most efficient car in the Subcompact Cars class for the 2019 model year is the BMW i3 at 113 MPG. The bar chart below puts the Toyota Mirai alongside the class best and the class average so you can see the full picture.
For broader context, the average new car of the 2019 model year (across all classes) returns 26.8 MPG. Larger vehicles pull the all-cars average down, so do not use that figure on its own to judge a small car or a hybrid. The full list of the most efficient cars of the 2019 model year is on its own page.
Year-over-year MPG for the Toyota Mirai
The EPA has rated the Toyota Mirai across 6 model years, from 2016 Toyota Mirai through 2026 Toyota Mirai. The numbers below are the best combined MPG figure the EPA published for each year, which lets you see when the car was at its most efficient and how recent generations stack up.
The 2016 Toyota Mirai returned 67 MPG. The most recent 2026 Toyota Mirai returns 72 MPG. That is an improvement of 5 MPG over 10 model years, the kind of gain that usually comes from smaller engines, hybrid systems, or aerodynamic redesigns.

Specifications
Engine, transmission, and drivetrain together drive most of the variation in fuel economy across trims. A larger engine moves the car with less effort but burns more fuel. A turbo lets a small engine punch above its weight, often without much MPG penalty. All-wheel drive adds traction and weight, and usually costs a couple of MPG compared with two-wheel drive of the same engine.
