The Toyota Mirai is rated 70.6 MPGe (71.7 city, 69.1 highway) — that is not petrol economy but the distance it covers on 33.7 kWh, the energy held in one gallon. Drawn from a socket it needs 47.7 kWh per 100 miles, so 12,000 miles a year costs about $973 at $0.17 a kWh.

City or highway — who is this car for
The Toyota Mirai is one of the cars that does better in town than out of it — 71.7 in the city against 69.1 on the highway. That is $20 a year in favour of the commuter stuck in traffic, and it usually means a hybrid drivetrain recovering energy every time you brake.
| Measure | Value | Reading |
|---|---|---|
| City | 71.7 MPGe | $959 a year if you only drive in town |
| Highway | 69.1 MPGe | $996 a year if you mostly commute |
| Gap | -2.6 MPGe (-4%) | Reversed — it does better in town than on the open road |
How the Mirai changed over the years
The Mirai peaked in 2025 at 74 MPGe (76 city, 71 highway) and was at its thirstiest in 2020 at 67 — 7 MPGe apart, or $98 a year in fuel between buying one year and the other. The 2026 car does 72. Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
