See this movement? Now imagine it over thousands of kilometers. Building an expedition vehicle is not just about assembling four fiberglass walls and filling them with furniture—it starts with proper engineering and design.
Every one of our projects begins with a detailed study of dimensions and weights, including chassis torsion calculations and proper load distribution. Every detail is analyzed, because this level of precision is what ensures a reliable, problem-free expedition vehicle over time.
A key component is the floor panel, a multilayer structure designed to combine structural strength, insulation, and low weight. From the inside out, it consists of a reinforced fiberglass layer, followed by a 12 mm plywood panel that provides stability and prevents deformation of the insulating foam.
Inside, there is a robust S355 steel frame—stronger than standard steel—built using different tube sections: 80x80x5 mm along the central longitudinal axis, 120x80x5 mm in the transverse sections where the 3-point subframe is mounted, and 60x80x5 mm along the sides. Flat steel inserts are integrated inside the tubes to increase thickness at mounting points and allow for strong, durable threaded connections.
The frame is filled with high-density polyurethane insulating foam (50 kg/m³), which provides thermal insulation and contributes to the overall rigidity of the structure. On the outside, a 3 mm fiberglass layer completes the panel, protecting it from external elements.
The subframe is directly integrated into the floor to keep the center of gravity as low as possible, improving stability and performance on all types of terrain. In addition, each vehicle features a custom-designed subframe, as every platform has different characteristics and requirements.
This solution also reduces the overall vehicle height and creates more usable space for technical compartments and underbody storage boxes. Fuel and AdBlue tanks can be positioned higher, avoiding interference with the chassis during off-road torsion, since there is no intermediate structure between the chassis frame and the living unit that could come into contact.
