Can I tow a caravan with an electric or a hybrid car?
Want an electric or hybrid car but also need to tow a caravan or trailer? It is possible, but only if you choose the right model
Camping and caravanning are popular hobbies for many in the UK. With the increase in the number of electric and hybrid cars on sale, many caravanners are beginning to look towards buying an electric or hybrid tow car.
In many ways, an electric car should make the perfect caravan hauler. The instant pulling power from their electric motors should make them better at towing than a petrol or diesel-engined car, while their low running costs should help owners save money during trips, too. In reality, that’s not always the case – most electric vehicles are not certified as fit for towing. However, all is not lost...
Why most electric vehicles are not able to tow a caravan
There are several reasons why electric cars aren’t used to tow caravans, but the biggest one is to do with something called 'type approval'. Whenever a car manufacturer wants to sell a new model, the vehicle in question has to be type approved. During the process, manufacturers can decide whether or not to approve the vehicle for towing – and in most instances, electric cars aren't certified.
There are some very good reasons for this. The first is to do with the weight of an electric car. They already weight more than equivalent petrol or diesel-powered cars because of their heavy batteries. 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 – which is only calibrated to the braking force needed for the vehicle itself – any extra braking force added by the caravan might complicate the onboard electronics. This isn't an insurmountable problem, though, and in time manufacturers may be able to develop systems that can factor in different weights.
Another issue is range. Caravanners often undertake long trips, which can be difficult in an electric car. Not only would drivers have to recharge regularly, but they'd also face significantly shorter real-world range than the car's published figure due to the added weight of the caravan. The extra weight could also strain the electric motors.
However, that's not to say an electric car can’t be used to tow. A handful of electric vehicles are certified for towing: the Tesla Model X is capable of pulling an impressive 2,270kg; Tesla has included a ‘trailer mode' that shuts off some of the car’s driver-assistance features and can apply brakes to individual wheels if it detects the trailer swaying behind.
Can plug-in hybrids be used for towing?
Because plug-in vehicles use a combination of electric and engine power, the issues discussed above that affect pure-electric vehicles are less pronounced. In fact, several plug-in hybrid vehicles have been certified for towing, including the Mitsubishi Outlander PHEV, Volvo XC90 Recharge, Volvo XC60 Recharge and BMW X5 hybrid, among others.
They come with impressive towing capacities, too. The Volvo XC60 Recharge T8 has a 2,100kg limit, going all the way up to 3,500kg for the Porsche Cayenne E-Hybrid. Smaller models like the Volkswagen Golf GTE can tow up to 1,600kg.
Many non-plug-in hybrid cars are also certified for towing, but their limits are smaller. The Toyota Prius and C-HR are limited to just 725kg, for example, while the Corolla can manage 750kg. The Toyota RAV4 can haul 1,650kg in all-wheel-drive hybrid form, while the plug-in version of the same car has a towing limit of 1,500kg. According to the Caravan & Motorhome Club, hybrid cars are currently the best choice for those looking for an alternative-fuel vehicle to tow a caravan with.
Can an electric car be towed?
If your hybrid or electric car breaks down, it shouldn’t be towed away, but instead 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 short distance. Consult your owner’s manual to find out what your manufacturer recommends.
