City or highway — who is this car for
The BMW X5 gives up 5.4 mpg the moment you leave the motorway — 22.6 out there against 17.2 in town, a 31% drop worth $534 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 | 17.2 mpg | $2,233 a year if you only drive in town |
| Highway | 22.6 mpg | $1,699 a year if you mostly commute |
| Gap | +5.4 mpg (31%) | Wide — this car dislikes traffic |
How the X5 changed over the years
The X5 peaked in 2026 at 25 mpg (23 city, 27 highway) and was at its thirstiest in 2000 at 14 — 11 mpg apart, or $1,207 a year in fuel between buying one year and the other. The 2026 car does 25. Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
