The current BMW 1-Series can tow up to 1,300 kg braked. Figures below are the strongest variant in each generation — lighter trims and engines tow less.
Unbraked (no trailer brakes): 750 kg.
| Years | Braked | Unbraked |
|---|---|---|
| 2004–2007 | 1,200 | 705 |
| 2007–2015 | 1,200 | 740 |
| 2015–2019 | 1,500 | 750 |
| 2019–2024 | 2,800 | 750 |
| 2024–present | 1,300 | 750 |
Towing capacity is the manufacturer-rated maximum for the model's strongest variant in each generation, not an average across trims — a base engine will tow less than the figure shown. Cars with an implausible source-data towing figure relative to their own kerb weight are excluded rather than shown with a guessed correction.
