City or highway — who is this car for
The Audi allroad gives up 5.7 mpg the moment you leave the motorway — 22.8 out there against 17.1 in town, a 33% drop worth $562 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 | 17.1 mpg | $2,246 a year if you only drive in town |
| Highway | 22.8 mpg | $1,684 a year if you mostly commute |
| Gap | +5.7 mpg (33%) | Wide — this car dislikes traffic |
How the allroad changed over the years
The allroad peaked in 2018 at 25 mpg (22 city, 30 highway) and was at its thirstiest in 2002 at 16 — 9 mpg apart, or $864 a year in fuel between buying one year and the other. The 2018 car does 25. Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
