City or highway — who is this car for
The Kia Sedona gives up 6.3 mpg the moment you leave the motorway — 22.9 out there against 16.6 in town, a 38% drop worth $636 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 | 16.6 mpg | $2,313 a year if you only drive in town |
| Highway | 22.9 mpg | $1,677 a year if you mostly commute |
| Gap | +6.3 mpg (38%) | Wide — this car dislikes traffic |
How the Sedona changed over the years

Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
