City or highway — who is this car for
The Toyota GR86 gives up 9.5 mpg the moment you leave the motorway — 30.5 out there against 21 in town, a 45% drop worth $570 a year. A wide gap punishes stop-and-start traffic; a narrow one means the car doesn't care where you drive it.
| Measure | Value | Reading |
|---|---|---|
| City | 21 mpg | $1,829 a year if you only drive in town |
| Highway | 30.5 mpg | $1,259 a year if you mostly commute |
| Gap | +9.5 mpg (45%) | Wide — this car dislikes traffic |

The GR86 peaked in 2023 at 25 mpg (21 city, 31 highway) and was at its thirstiest in 2025 at 24 — 1 mpg apart, or $64 a year in fuel between buying one year and the other. The 2025 car does 24. Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
