City or highway — who is this car for
The Audi SQ8 gives up 6 mpg the moment you leave the motorway — 20.6 out there against 14.6 in town, a 41% drop worth $766 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 | 14.6 mpg | $2,630 a year if you only drive in town |
| Highway | 20.6 mpg | $1,864 a year if you mostly commute |
| Gap | +6 mpg (41%) | Wide — this car dislikes traffic |
