The current Lexus LS 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): 730 kg.
| Years | Braked | Unbraked |
|---|---|---|
| 1990–2006 | 2,000 | 750 |
| 2006–2010 | 2,000 | 700 |
| 2018–2021 | 1,600 | 730 |
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.
