Can I tow a caravan with an electric or a hybrid car?
Camping and caravanning is a popular pastime for many Brits. With the rise in the number of electric and hybrid cars on sale, many caravanners will start to look into whether their next caravan hauler should be electric or not.
In many ways, an electric car makes great sense as a caravan tower. The instant pulling power from the electric motors should make them better at towing than a petrol or diesel engine, while the low running costs should help owners save money during trips, too.
In reality, that’s not really the case, as most electric vehicles are not fit for towing. All is not lost, however...
Why most electric vehicles are not fit for towing a caravan
There are several reasons for why electric vehicles aren’t used to tow caravans but the biggest one is to do with type approval.
Whenever a car manufacturer wishes to introduce a new model to the market, the vehicle in question has to be type approved. During the process, manufacturers can decide whether or not to approve the vehicles for towing – and in most instances electric cars will not be certified for this.
There are some very good reasons for this. The first is to do with the weight of an electric car. They already have a big weight penalty over equivalent diesel or petrol-powered cars thanks to the heavy batteries onboard.
Added weight from the caravan or trailer would affect things like the brakes – they wouldn’t be as effective and might struggle to cope with the even heavier load. As most electric cars today come with regenerative braking that’s only calibrated to the braking force of the vehicle, additional braking force added by the caravan might complicate the electronics onboard.
Another issue is range. Caravans often do long trips, which would be difficult in an electric car. Not only would drivers have to recharge their vehicle regularly, but they would also face a significantly smaller real-world range thanks to the added weight of the caravan. The extra weight could also strain the electric motors and related components.
However, that is not to say an electric car can’t be used to tow. Currently the only pure electric vehicle certified for towing is the Tesla Model X. It’s capable of towing an impressive 2,270kg, and Tesla has built it with a ‘trailer mode’. This shuts off some of the car’s drive-assistance features that wouldn’t work as well with a trailer.
The Model X also comes with a stabilising feature that applies brakes to individual wheels if it detects the trailer swaying behind.
Can plug-in hybrids be used for towing?
Because plug-in vehicles come with a combination of electric and engine power, the issues that affect pure electric vehicles are less pronounced.
In fact, there are several plug-in hybrid vehicles that have been certified for towing, including the Mitsubishi Outlander PHEV, Volvo XC90 T8, Volvo XC60 T8, Audi Q7 e-tron and BMW X5 40e, among others.
They come with impressive towing capacities, too. The Volvo XC60 T8 Twin Hybrid comes with a 2,100kg limit, going all the way up to 3,500kg for the Porsche Cayenne e-Hybrid.
Smaller models like the Audi A3 Sportback e-tron and the VW Golf GTE can tow up to 1,600kg.
According to the Caravan and Motorhome Club, hybrids are currently the best choice for those looking for an alternative fuel vehicle tow a caravan with. This is because hybrids come with the best combination of performance and economy when towing a caravan.
Can an electric car be towed?
If your hybrid or electric car breaks down, it shouldn’t be towed away but rather placed on a flatbed trailer. This is to avoid harming the electronics on board, such as the traction motor that generates electricity when coasting.
Most manufacturers recommend owners contact their breakdown provider and specifically ask for a flatbed truck. However, in some instances, an electric car can be towed with the front-wheels lifted, but this is often limited to a small distance. Consult your owner’s manual to find out what your manufacturer recommends.
