The current Mazda 3 covers up to 1,244 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 2003–2006 | Combustion | 1,100 |
| 2006–2009 | Combustion | 1,146 |
| 2009–2011 | Combustion | 1,250 |
| 2011–2013 | Combustion | 1,279 |
| 2013–2016 | Combustion | 1,342 |
| 2016–present | Combustion | 1,244 |
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.
