City or highway — who is this car for
The Kia Sephia gives up 7 mpg the moment you leave the motorway — 29.7 out there against 22.7 in town, a 31% drop worth $399 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 | 22.7 mpg | $1,692 a year if you only drive in town |
| Highway | 29.7 mpg | $1,293 a year if you mostly commute |
| Gap | +7 mpg (31%) | Wide — this car dislikes traffic |
How the Sephia changed over the years
The Sephia peaked in 1995 at 28 mpg (25 city, 32 highway) and was at its thirstiest in 2000 at 23 — 5 mpg apart, or $299 a year in fuel between buying one year and the other. The 2001 car does 24. Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
