The current Mitsubishi ASX covers up to 1,091 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 2010–2012 | Combustion | 1,145 |
| 2012–2016 | Combustion | 1,400 |
| 2016–2018 | Combustion | 1,370 |
| 2018–2019 | Combustion | 1,105 |
| 2019–2021 | Combustion | 969 |
| 2023–2024 | Combustion | 848 |
| 2024–present | Combustion | 1,091 |
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.
