The current Mitsubishi Galant covers up to 914 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 1980–1984 | Combustion | 714 |
| 1984–1988 | Combustion | 857 |
| 1988–1993 | Combustion | 952 |
| 1993–1997 | Combustion | 941 |
| 1997–2004 | Combustion | 914 |
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.
