The current Saab 9-5 covers up to 1,273 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 1999–2001 | Combustion | 806 |
| 2001–2005 | Combustion | 1,087 |
| 2005–2010 | Combustion | 1,103 |
| 2011–2011 | Combustion | 1,273 |
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.
