The current Suzuki Alto covers up to 854 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 1981–1986 | Combustion | 397 |
| 1986–1996 | Combustion | 469 |
| 1994–2002 | Combustion | 648 |
| 2002–2006 | Combustion | 714 |
| 2009–2015 | Combustion | 854 |
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.
