The current SsangYong Rexton covers up to 1,114 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 2002–2009 | Combustion | 930 |
| 2011–2013 | Combustion | 907 |
| 2013–2019 | Combustion | 1,114 |
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.
