The current Kia Rio covers up to 900 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 2000–2003 | Combustion | 616 |
| 2003–2005 | Combustion | 672 |
| 2005–2011 | Combustion | 957 |
| 2011–2015 | Combustion | 1,344 |
| 2015–2017 | Combustion | 1,194 |
| 2017–2020 | Combustion | 1,216 |
| 2020–2024 | Combustion | 900 |
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.
