Can I tow a caravan with an electric or a hybrid car?
You need to choose your model carefully if you want to tow a caravan or trailer with a hybrid or electric car
There are more electric and hybrid cars on sale now than ever before, and it’s likely that you’re at least considering one as your next car. Yet if you regularly tow a caravan or trailer, you might be concerned about their ability to pull – but we’re here to help.
Hybrid and electric cars have lots of torque from their electric motors, so they ought to have lots of pulling power. Plus, low running costs are key on longer trips, so they should make good tow cars.
Yet there are a number of electrified models that aren’t rated to tow a heavy trailer, or any kind of braked trailer at all, so it’s not just a case of the powertrain being appropriate – the authorities need to authorise it, too. But there is some good news. Read on to find out all you need to know about towing a caravan or trailer with a hybrid or electric car.
Why some electric cars aren't able to tow
The main reason you can’t tow a caravan with some hybrid or electric cars is because of something called type approval. This is the certification process carmakers go through with new models, and many decide not to have these models certified for towing safely.
One of the reasons for this is weight, since this plays a big part in the approval process for towing. Heavy batteries mean that these models tend to be heavy overall, and the extra weight from the caravan or trailer could mean beefier brakes were needed. This bumps up the cost to produce the car, and since most people don’t tow, it’s seen as not worth the cost.
There’s also the matter of regenerative braking, something most EVs and hybrids use. It’s calibrated to the braking force needed for the vehicle itself, so any extra braking force (and the weight) added by the caravan might complicate things for 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. Caravan owners often undertake long trips, which can be an issue for some electric models. 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 no electric car can be used to tow. A handful of EVs are certified for it: 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. Meanwhile, the Audi e-tron and Mercedes EQC can both tow up to 1,800kg. The Jaguar I-Pace is also rated for towing, although it's much less capable in this respect, with a maximum figure of 750kg, while the Volkswagen ID.4 family SUV can haul up to 1,000kg.
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. The Land Rover Defender P400e is rated at 3,000kg.
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.
