The current Opel Grandland covers up to 692 km on a full charge. Figures below are the longest-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 2017–2021 | Electric | 65 |
| 2021–2024 | Electric | 59 |
| 2024–present | Electric | 692 |
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.
