The current Audi TT covers up to 833 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 1998–2006 | Combustion | 689 |
| 2006–2014 | Combustion | 1,132 |
| 2014–2019 | Combustion | 1,163 |
| 2019–2023 | Combustion | 833 |
Range is calculated from each variant’s fuel tank capacity and combined-cycle consumption (tank ÷ consumption × 100), for the best-range variant in each generation — real-world range varies with driving style and conditions. Figures outside a plausible range for the tank size are excluded.
