City or highway — who is this car for
The Audi Q8 gives up 5.2 mpg the moment you leave the motorway — 22.6 out there against 17.4 in town, a 30% drop worth $508 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 | 17.4 mpg | $2,207 a year if you only drive in town |
| Highway | 22.6 mpg | $1,699 a year if you mostly commute |
| Gap | +5.2 mpg (30%) | Wide — this car dislikes traffic |

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