There are a few electric cars that'll be able to tow your caravan. 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. We don't have any data on what range you can expect when towing but, obviously, it'll be considerably less than the standard WLTP range figure. Bear in mind that technology has moved on rapidly over the last 10 years and will continue to do so over the coming years - by 2030, there'll be a much wider range of EVs capable of towing. New plug-in hybrid vehicles will be on sale until 2035 and these are well-suited to towing.
