The current Opel Vectra can tow up to 1,600 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 |
|---|---|---|
| 1988–1992 | 1,350 | 650 |
| 1992–1995 | 1,350 | 600 |
| 1995–1999 | 1,500 | 700 |
| 1999–2002 | 1,500 | 725 |
| 2002–2009 | 1,600 | 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.
