The annual Düsseldorf Caravan Salon is approaching rapidly, and Dethleffs is gearing as much as present certainly one of its most progressive, ground-up rethinks but. Following within the German model’s long-running custom of eco-friendly Düsseldorf present automobiles, the E.Dwelling Eco contains a extremely sustainable building atop an all-electric Ford chassis. Gone is the same old array of artificial supplies, changed with extra pure alternate options like a flax-composite shell, corn furnishings and sheep’s wool upholstery.
With roots gnarling all the best way again to 1931, Dethleffs is without doubt one of the caravan business’s pioneers at massive, and in 2017, it emerged as one of many business’s trailblazers in sustainable innovation. Who can overlook the photo voltaic panel-covered E.Home concept it introduced that 12 months, or the E.Home Coco concept with which it adopted it up? The latter kickstarted the thought of a self-propelled motorized trailer simply now making its way to market. In 2019, Dethleffs picked up the lead on camper van electrification, debuting the production-bound plug-in hybrid Globevan camper.

Apparently, it was Dethleffs’ sister Erwin Hymer Group model Bürstner that confirmed the primary all-electric Ford Transit-based camper van in 2022. Dethleffs was seemingly on a hiatus from inexperienced ideas and launches for a couple of years, focusing in on growing an adventurous lineup of compact, thrill-seeking AWD and toy-hauling motorhomes.
Now Dethleffs is again within the driver’s seat of the envelope-pushing eco-RV sport, and it is previewing what the following era of environmentally influenced design might appear like in RV manufacturing. The corporate notes that whereas its earlier eco fashions had been centered round electrification of powertrain and onboard RV tools, its new course will prolong past car utilization into materials choice and provide methods.
That does not imply it is pulling again on electrification, although – the E.Dwelling Eco idea nonetheless begins with an all-electric base car. Dethleffs one-ups Bürstner’s E-Transit camper van with a bigger E-Transit Class C motorhome. The corporate says the MY2023 E-Transit brings 181 hp of drive energy and a 149-mile (240-km) WLTP vary.
Dethleffs’ technical workforce has labored onerous to take advantage of out of the E-Transit’s restricted vary by optimizing aerodynamics. It is changed the facet mirrors with a rear-view digital camera system, swapped the rear wheel arches for dropped bodywork and pulled off roof elements for smoother airflow, all to assist eke out each final mile-per-charge.

Sustainable supplies aren’t fairly as flashy and attention-grabbing as electrical powertrain applied sciences, however they’ve begun to search out experimental and nascent manufacturing use in RVs and the mobility business at massive. For its half, Dethleffs foregoes the frequent fiberglass motorhome field building in favor of a flax composite provided by German specialist Greenboats.
Greenboats developed its flax-based pure fiber composite supplies for the boat business again in 2013 and has since expanded into different industries, together with sporting items and RVs, by spinoff model Round Buildings. Final 12 months’s Düsseldorf Caravan Salon welcomed the Greenlander Sherpa, an Iveco Every day 4×4-based overland expedition car with a dwelling module made out of Round Buildings’ flax composite. The primary manufacturing run has really offered out, however Greenlander is planning future runs atop the Mercedes-Benz Sprinter AWD and Atego.

The flax composite in use within the E.Dwelling Eco’s building does not remove plastic fully as a result of the pure fibers are nonetheless set in a resin, simply as glass fibers can be in fiberglass. Dethleffs does stress that the resin on this case options 40 p.c pure content material, together with linseed oil from the identical sort of crops from which the flax is harvested. In response to Dethleffs, the flax fibers themselves provide comparable structural properties to glass however with a carbon footprint that is 80 p.c decrease.
To insulate these naturally flaxxy partitions, Dethleffs makes use of a foam constructed from recycled PET bottles, one thing we have seen from different RV producers, together with Escapod. Dethleffs says that the fabric can also be recyclable, permitting it to be repurposed on the finish of the RV’s lifecycle.
The fabric switch-up continues inside, the place Dethleffs makes use of one thing we do not recall coming throughout up to now: “popcorn panels.” Made out of non-food-grade maize, the fabric was developed in 2018 at Germany’s College of Göttingen and has been regularly refined within the years since. It is encased inside outer veneers constructed from oiled oak, providing properties corresponding to plywood however with a claimed half the burden. The E.Dwelling Eco makes use of it within the kitchen counter and eating desk tops.
The ground under these furnishings is constructed from fairly a pure little formulation of linoleum that comes with a mixture of jute cloth, linseed oil, cork flour and pure resins. The upholstery cloth, in the meantime, is a processed sheep’s wool, promising a heat, snug really feel and sturdy, stain-resistant, flame-retardant efficiency.

Like the unique 2017 E.Dwelling, the E.Dwelling Eco is designed to run fully on electrical energy, much more frequent in campers in the present day than eight years in the past. Dethleffs does not shoot for a completely self-sufficient, off-grid electrical system, nonetheless, tapping into shore energy to run a warmth pump and separate water heater, each provided by Truma. The low-noise warmth pump distributes heating by flooring ducts, assisted by electrical boosters that speed up heating of the air. Cooling is provided by ceiling ducts.
The E.Dwelling Eco does not embrace the full-body photo voltaic swimsuit of the unique E.Dwelling, however Dethleffs has built-in a bit of greater than half the unique idea’s capability, putting in 1,700 watts of panels extra subtly on the roof and rear wall to energy the onboard battery.
“In our improvement tasks, we routinely consider new supplies based mostly on renewable or recycled uncooked supplies, in addition to environmentally pleasant improvements from our suppliers, to find out their practicality in caravanning purposes,” mentioned Dethleffs Managing Director Bernhard Kibler. “A few of these approaches might discover their approach into manufacturing automobiles sooner or later, whereas others nonetheless must show their sensible viability.”
In different phrases, the E.Dwelling Eco shouldn’t be meant to be a direct preview of a manufacturing mannequin. Then once more, Hymer brass had a sentiment similar to Kibler’s concerning the then-highly unique 2019 Vision Venture camper van concept earlier than bringing it to market three years later, most of its spectacular, otherworldly options nonetheless intact.
So possibly a lot of the E.Dwelling Eco’s approaches find yourself proving their “sensible viability” to the purpose Dethleffs sends the entire car by to manufacturing strains.
We’ll get a better have a look at the E.Dwelling Eco idea as soon as the 2025 Caravan Salon will get underway in August.
