There are a few electric cars that are able to tow. These include the Polestar 2 (towing capacity 1500kg), Audi e-tron (1800kg) and Tesla Model X (2250kg). EVs have a number of advantages when it comes to towing: they're usually quite heavy (a good thing when towing) and provide instant torque. They also have good brakes with regenerative braking helping to slow down, which will help keep a trailer or caravan under control.
