The current Suzuki Swift covers up to 881 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 1984–1986 | Combustion | 564 |
| 1986–1989 | Combustion | 623 |
| 1989–2003 | Combustion | 755 |
| 2005–2010 | Combustion | 957 |
| 2010–2014 | Combustion | 857 |
| 2014–2017 | Combustion | 1,105 |
| 2017–2024 | Combustion | 881 |
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.
