The current BMW 1-Series covers up to 1,140 km on a full tank, based on combined-cycle consumption. Figures below are the best-range variant in each generation.
| Years | Powertrain | Range |
|---|---|---|
| 2004–2007 | Combustion | 911 |
| 2007–2012 | Combustion | 1,159 |
| 2011–2015 | Combustion | 1,368 |
| 2015–2019 | Combustion | 1,333 |
| 2019–2024 | Combustion | 1,316 |
| 2024–present | Combustion | 1,140 |
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.
