The current BMW 6-Series can tow up to 1,500 kg braked. Figures below are the strongest variant in each generation — lighter trims and engines tow less.
Unbraked (no trailer brakes): 705 kg.
| Years | Braked | Unbraked |
|---|---|---|
| 1976–1982 | 1,600 | 650 |
| 1982–1989 | 1,800 | 750 |
| 2004–2007 | 1,200 | 665 |
| 2007–2011 | 1,500 | 705 |
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.
