The following was reported by New Atlas.
Building upon the foundation it laid with last year’s E.Home Eco, Dethleffs is showing an even more innovative, envelope-pushing green RV concept at this year’s Düsseldorf Caravan Salon. The all-new C.Core brings biomimicry, solar expansion and closed-loop recycling into the fold to create a mobile environment in which campers treat every resource with the utmost thought and care. The space also transforms to help travelers get the most out of their trip.
We looked back at Dethleffs’ near-decade-long history of presenting environmentally friendly design studies in last year’s E.Home Eco article, so we won’t rehash it beyond saying that the all-new 2026 C.Core concept follows not only all those previous-year concept debuts but also the C.Fold expandable caravan concept Dethleffs prepared for the CMT show this past January. So it appears “C” has officially replaced “E” as the new buzzword in green RV design, at least for now, in Dethleffs’ HQ city of Isny im Allgäu.
All of Dethleffs’ eco-friendly concepts have been strictly design studies not meant for production, and the C.Core is no exception. But while there are no plans for production, it will serve as a rolling R&D lab in which potential technologies can be explored and tested in real world conditions. In that way, it appears to draw more closely to the annual concepts developed by other Erwin Hymer Group brands, which often serve as test and launch beds for rather wild technologies and features.
With the C.core, Dethleffs begins by sculpting a new motorhome module atop a Volkswagen Crafter van chassis. Relying heavily on a material called Necto, a specialized bird-bone-inspired form of multi-layer aluminum panels, the company builds out a Class C motorhome that offers a calculated weight savings between 25 and 45 kg (55 and 99 lb) in comparison to one built from more conventional materials. Dethleffs’ use of recycled PET for insulation follows in the vein of a few RV products we’ve looked at, including Escapod teardrop trailers.
Further building up the C.core’s green credentials, Dethleffs equips the RV with what it classifies as a virtually self-sufficient electrical system based on an expandable “solar flower” rooftop panel array. The panels store within the roof rails when driving but expand at camp to deliver up to 600 watts of charging while doubling as an awning, saving space and weight as compared to separate awning and charging systems.
Coupled with a 400-Ah lithium battery bank, Dethleffs says the system could deliver independent power between May and September. Assuming that assessment is based on German weather conditions, it could probably run for longer, perhaps year-round, somewhere like the Middle East or American Southwest.
The C.core interior is laid out in a fairly conventional fashion, with a set of raised longitudinal single beds anchoring the rear, a dining lounge up front, and a kitchenette and bathroom between them. Dethleffs works some innovation into the individual areas, however, ensuring campers can get the most out of their time in the finite cabin space.
