German manufacturer Dethleffs presented the c.fold prototype, a folding caravan designed for towing by electric cars, at the CMT 2026 show in Stuttgart. In road mode the caravan measures 1.65 m high, 1.90 m wide and 5.49 m long, and at the campsite it deploys electrically to a height of about 2.18 m, doubling the living volume. The kerb weight is under 1,000 kg with around 400 kg payload. According to aerodynamic simulations, the profile can restore up to 100 km of range compared with a conventional caravan of similar size. Clever Campen magazine tested the prototype behind a Volkswagen ID.4 GTX 77 kWh: average consumption was about 22.4 kWh/100 km versus 36 kWh/100 km with a standard caravan, a reduction of around 38%. The construction uses Alucore honeycomb aluminium panels with recycled PET insulation, a linoleum floor, a Goldschmitt independent air suspension with app-based weighing, about 300 W of solar panels, 300 Ah lithium batteries and a 2,000 W inverter.
