The current Subaru Forester covers up to 593 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 1997–2002 | Combustion | 667 |
| 2002–2005 | Combustion | 706 |
| 2005–2008 | Combustion | 645 |

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.
