Caravan, roof box, or bike rack: How much range do they cost electric cars in Belgium?

Towing a caravan with an electric car can slash its driving range by a third, according to new research. Even smaller additions like a bicycle carrier or a roof box significantly impact how far an electric vehicle can travel, reducing its range by up to 11 percent.

These figures come from an investigation by the Belgian mobility organization VAB. The research provides concrete data on the energy consumption associated with common accessories used by electric car owners. The findings highlight a practical challenge for EV drivers who wish to transport extra gear or tow trailers.

While it's generally known that external additions increase energy usage, VAB's study quantifies the exact impact. This information is crucial for electric vehicle owners planning longer journeys or considering the purchase of accessories like roof boxes or bike racks. The substantial range reduction associated with towing a caravan, in particular, suggests that long-distance travel with such loads may require careful planning and frequent charging stops.
