City or highway — who is this car for
The Subaru Ascent gives up 6.1 mpg the moment you leave the motorway — 26.5 out there against 20.4 in town, a 30% drop worth $433 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 | 20.4 mpg | $1,882 a year if you only drive in town |
| Highway | 26.5 mpg | $1,449 a year if you mostly commute |
| Gap | +6.1 mpg (30%) | Wide — this car dislikes traffic |
How the Ascent changed over the years
The Ascent peaked in 2022 at 23 mpg (21 city, 27 highway) and was at its thirstiest in 2026 at 22 — 1 mpg apart, or $75 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.
