The current Mazda 626 covers up to 1,231 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 1983–1987 | Combustion | 968 |
| 1987–1993 | Combustion | 952 |
| 1991–1998 | Combustion | 882 |
| 1997–2002 | Combustion | 1,231 |
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.
