The 2026 Adria Supersonic sets a new standard for luxury motorhoming, bringing together sophisticated design, advanced engineering, and refined comfort. Built exclusively on the Mercedes-Benz base vehicle, Supersonic combines precision performance with sleek, automotive-inspired styling and a bold silver metallic exterior. With its exclusive front grille, HELLA daytime running lights, Bi-LED headlamps, dynamic rear diffuser design, and wide-angle heated mirrors, every detail speaks of elegance and purpose.

Step inside and you’ll find a seamless, single-level double floor that integrates insulation, utilities, and storage for year-round performance. The 650mm wide habitation door with hidden hinges, two-way lock, and privacy window leads into a beautifully crafted living space inspired by modern home and yacht design. Choose between an L-shaped lounge or face-to-face dinette, both offering a contemporary open-plan layout with premium fabrics, ambient and LED lighting, and a low dividing wall that enhances flow and spaciousness.

The innovative kitchen is designed for serious cooking, with ample work surfaces, high-quality appliances, and thoughtful storage, while the luxurious spa-style bathroom provides a haven of relaxation with quality fittings, generous storage, and mood lighting. At the rear, the master suite offers a choice of layouts – a king-size central bed or longitudinal twin beds with electrical adjustment, slatted frames, and Luxe mattresses – ensuring ultimate comfort at the end of every day.

Practicality is at the heart of Supersonic too, with a Central Service Box that neatly houses all utility hook-ups in one place, plus a 150L fresh water tank with electronic fresh and grey water disposal. An integrated awning with adapter extends your living space outdoors, while the rear-view camera adds peace of mind on the road.

Refined, elegant, and engineered without compromise, the Adria Supersonic 2026 is more than a motorhome – it’s the ultimate expression of design and performance for those who demand nothing less than the very best.
