According to a media report, only a few electric cars are suitable as pulling vehicles for pulling a caravan or heavy trailer. As Auto, Motor und Sport (AMS) reports, only a few manufacturers offer a towbar. Many manufacturers also do not mention permissible axle load
According to these reports, ten electric models are suitable as pulling vehicles, but only four of them – all of the SUVs – could pull a large caravan or horse trailer: The Tesla Model X with a towing capacity of up to 2250 kg (braked), the Audi e-Tron, the Audi e-Tron Sportback as well as Mercedes EQC with up to 1800 kg each. The Polestar 2 and the Volvo XC40 Recharge, for example, can still pull a medium-sized caravan or trailer weighing up to 1500 kg. BMW iX3, Ford Mustang Mach-E and Jaguar I-Pace can handle up to 750 kg. With the Tesla Model 3, the trailer loads varied depending on the version.
The reason for the limited trailer suitability of e-cars is that a trailer, due to its weight and unfavourable aerodynamics, significantly increases the power consumption and thus limits the range. In the car magazine’s test with an Audi e-tron and a Mercedes EQC with a caravan weighing 1600 kg each, the range was halved. AMS concludes that the range might then still be sufficient for shorter weekend trips. For longer holiday trips, however, this represents a considerable loss of comfort.
The manufacturers of popular electric cars such as Hyundai Kona Elektro, Kia e-Niro, Nissan Leaf, Mazda MX-30 and VW ID.3 do not provide any information on towing and drawbar loads. VW, however, has newly offered a trailer coupling for the ID.3 for a low drawbar load, for example to mount a bicycle carrier.
