City or highway — who is this car for
The Honda Odyssey gives up 7.7 mpg the moment you leave the motorway — 25.7 out there against 18 in town, a 43% drop worth $639 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 | 18 mpg | $2,133 a year if you only drive in town |
| Highway | 25.7 mpg | $1,494 a year if you mostly commute |
| Gap | +7.7 mpg (43%) | Wide — this car dislikes traffic |
How the Odyssey changed over the years
The Odyssey peaked in 2026 at 22 mpg (19 city, 28 highway) and was at its thirstiest in 2001 at 18 — 4 mpg apart, or $388 a year in fuel between buying one year and the other. The 2026 car does 22. Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
