The current Mini Countryman covers up to 871 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 2010–2014 | Combustion | 1,068 |
| 2014–2017 | Combustion | 1,119 |
| 2017–2020 | Combustion | 1,244 |
| 2020–2024 | Combustion | 1,214 |
| 2023–present | Combustion | 871 |
| 2024–present | Electric | 497 |
Range is the manufacturer-rated maximum for the longest-range variant in each generation. Electric generations use the rated battery range; combustion generations are calculated from tank capacity and combined-cycle consumption. Figures outside a plausible range are excluded rather than shown with a guessed correction.
