The current Audi 80 covers up to 1,245 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 1978–1981 | Combustion | 1,015 |
| 1981–1984 | Combustion | 1,063 |
| 1984–1986 | Combustion | 1,133 |
| 1986–1991 | Combustion | 1,283 |
| 1991–1995 | Combustion | 1,245 |
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.
