The current BMW 8-Series covers up to 1,015 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 1989–1999 | Combustion | 789 |
| 2018–2022 | Combustion | 1,082 |
| 2022–2026 | Combustion | 1,015 |
Range is calculated from each variant’s fuel tank capacity and combined-cycle consumption (tank ÷ consumption × 100), for the best-range variant in each generation — real-world range varies with driving style and conditions. Figures outside a plausible range for the tank size are excluded.
