The current Bentley Flying Spur covers up to 80 km on a full charge. Figures below are the longest-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 2013–2020 | Combustion | 826 |
| 2020–2024 | Combustion | 776 |
| 2024–present | Electric | 80 |
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.
