The current Peugeot 508 covers up to 63 km on a full charge. Figures below are the longest-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 2010–2014 | Combustion | 1,263 |
| 2014–2018 | Combustion | 1,286 |
| 2019–2026 | Electric | 63 |
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.
