The current Suzuki Ignis covers up to 821 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 2001–2006 | Combustion | 641 |
| 2003–2006 | Combustion | 780 |
| 2016–2020 | Combustion | 744 |
| 2020–2024 | Combustion | 821 |
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.
