City or highway — who is this car for
The Audi SQ5 gives up 6 mpg the moment you leave the motorway — 24.3 out there against 18.3 in town, a 33% drop worth $518 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 | 18.3 mpg | $2,098 a year if you only drive in town |
| Highway | 24.3 mpg | $1,580 a year if you mostly commute |
| Gap | +6 mpg (33%) | Wide — this car dislikes traffic |
