City or highway — who is this car for
The BMW XM gives up 5 mpg the moment you leave the motorway — 17 out there against 12 in town, a 42% drop worth $941 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 | 12 mpg | $3,200 a year if you only drive in town |
| Highway | 17 mpg | $2,259 a year if you mostly commute |
| Gap | +5 mpg (42%) | Wide — this car dislikes traffic |
