The current BMW iX3 covers up to 520 km on a full charge. Figures below are the longest-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 2020–present | Electric | 520 |
Range is the manufacturer-rated maximum for the longest-range variant in each generation, not an average across trims — smaller-battery versions go less far. Figures with an implausible range for their powertrain are excluded rather than shown with a guessed correction.
