The current Lancia Delta covers up to 1,261 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 1980–1983 | Combustion | 536 |
| 1983–1993 | Combustion | 792 |
| 1993–1998 | Combustion | 823 |
| 1998–2000 | Combustion | 761 |
| 2008–2015 | Combustion | 1,261 |
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.
