The current Audi A4 can tow up to 1,900 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 |
|---|---|---|
| 1996–2001 | 1,800 | 750 |
| 2001–2008 | 2,000 | 750 |
| 2008–2024 | 1,900 | 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.
