Dethleffs has tested a prototype caravan called C.Fold, developed to increase the range of electric cars while towing. The tests took place in the Allgäu region with a Volkswagen ID.4 GTX featuring a 77 kWh battery. Without a trailer, the ID.4 covers about 470 km, and with the C.Fold attached the range should remain at least 300 km. The prototype is 1.65 m high and 1.92 m wide, uses air suspension and lacks a conventional chassis. Individual approval was granted after the chassis number, originally stamped on the left side of the drawbar instead of the right, was corrected.
