Some plug-in hybrids can tow, and some are not rated to tow anything at all. The rating is set model by model and market by market, and it often runs lower than the petrol version of the same car, because the battery takes up part of the car’s weight allowance. If towing is why you are buying, the rating of the exact car in front of you is the first check, before price and before electric range.
Key Takeaways
- Tow ratings for plug-in hybrids are set per model, trim and market, and many models are not rated at all.
- Towing empties the small battery early; the petrol engine does the sustained work, which is the PHEV’s real towing advantage.
- Check the rating, the loaded trailer weight, any required towing package and the manual’s brake rules before you sign.
Where the Rating Lives
The only figures that count are the maker’s own, for your exact car:
- The owner’s manual for your model, trim and model year; it governs warranty and safe use.
- The maker’s specification page for your market. A rating quoted for another country, trim or engine does not transfer to your car.
- The dealer, in writing. A verbal “it should manage a small trailer” is not a rating. If the manual says the car is not rated for towing, that is the answer; fitting a tow bar anyway does not change it.
Why Plug-In Hybrid Ratings Run Lower
Three things work against a plug-in hybrid. First, weight: the battery and motor sit inside the same gross weight limit as everything else, so payload and towing allowance shrink. Second, sustained load: towing holds the engine and motor at high output for long stretches, which is harder to cool than a short climb. Third, specification: on some models the full rating depends on a factory towing package, and the same car without it is rated lower or not at all. None of this means a rated plug-in hybrid tows badly; it means the number, not the badge, decides.
| What you are checking | Where it is decided | Common mistake |
|---|---|---|
| Tow rating for your exact car | Manual and market specification | Using the petrol version’s figure, or another market’s. |
| Your trailer’s real weight | Loaded weight, not the brochure’s empty weight | Comparing the rating against an unloaded trailer. |
| Whether a towing package is required | Maker’s specification for your trim | Assuming the headline rating applies to every trim. |
| Trailer brake requirements | Manual for your car and trailer weight | Guessing from the tow bar fitter’s advice alone. |
What Towing Does to the Electric Side
A trailer’s weight and drag drain a small battery quickly. As our guide to plug-in hybrid charging notes, most PHEV batteries hold roughly 10 to 25 kWh. Expect the electric miles to go early in a towing trip. After that, the petrol engine sustains the tow, and that is the plug-in hybrid’s genuine towing advantage over a battery-electric car: no charge-stop planning mid-tow, and no unhitching at a fast charger to reach the cable. The electric side is for the school run and the commute; the engine is for the caravan.
Charging at the Ends of the Tow Day
Because the battery contributes least while towing, towing-day charging is mostly about the ends of the trip. Charge fully at home the night before, and top up at the destination if a suitable supply is available and the site permits it. A three-phase CEE portable such as the EV-ACS3205PE 22 kW portable charger or the ACS1605PE 11 kW portable charger suits campsite and holiday-park hook-ups in Europe; the car still only accepts what its on-board charger allows, as with any Level 2 charging.

Frequently Asked Questions
Does towing damage a plug-in hybrid’s battery?
Towing within the maker’s published rating, following the manual, is a designed use of the car. The risk sits in exceeding the rating or ignoring the manual’s requirements, which is also where warranty problems start. If towing is central to your use, confirm the position with the maker before buying.
Does a plug-in hybrid tow better than a petrol car?
Electric torque helps when pulling away, but torque is not the limiting factor. The published rating decides what you may tow, and on many plug-in hybrids it is lower than the petrol equivalent’s. Compare ratings, not impressions.
My plug-in hybrid has no tow rating, but a tow bar is available. Can I fit it?
An accessory existing is not a rating. If the maker does not rate your car for towing, a fitted bar does not create one, and towing anyway can put you outside the manual, your warranty and your insurance terms. Treat “not rated” as final for that car.
