The current BYD Dolphin covers up to 427 km on a full charge. Figures below are the longest-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 2023–present | Electric | 427 |
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.
