The current Maserati GranTurismo covers up to 435 km on a full charge. Figures below are the longest-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 2007–2018 | Combustion | 625 |
| 2018–2021 | Combustion | 601 |
| 2023–present | Electric | 435 |
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.
