City or highway — who is this car for
The Audi TTS gives up 5.8 mpg the moment you leave the motorway — 28.8 out there against 23 in town, a 25% drop worth $337 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 | 23 mpg | $1,670 a year if you only drive in town |
| Highway | 28.8 mpg | $1,333 a year if you mostly commute |
| Gap | +5.8 mpg (25%) | Typical for its type |
How the TTS changed over the years
The TTS peaked in 2023 at 26 mpg (23 city, 31 highway) and was at its thirstiest in 2021 at 25 — 1 mpg apart, or $59 a year in fuel between buying one year and the other. The 2023 car does 26. Jumps usually mark a new generation or a new engine; dips often mean a heavier body or added all-wheel drive.
