X-Class safety truck by Carlex Design
Carlex Design's Mercedes X-Class safety truck concept is one of the most dramatic custom pickup builds to come out of Europe, transforming Mercedes-Benz's production X-Class into a carbon fiber safety vehicle ready for race track deployment. Built by the world-renowned Polish custom house Carlex Design, the concept merges motorsport-grade hardware with signature aggressive styling.
Who Is Carlex Design?
Carlex Design is a globally recognised custom house based in Poland, specialising primarily in bespoke vehicle interior transformations. Their portfolio covers an extraordinary range of styles: from a steampunk Mini Countryman and a raw copper Yamaha V-Max to a charcoal-themed Dodge Challenger Hellcat. For exterior work, they have also tackled ambitious builds on Rolls-Royce Phantoms, and their real passion lies with pickup trucks. The brand's standard production line has included customised versions of the VW Amarok, Nissan Navara, Toyota Hilux, Fiat Fullback, and Mitsubishi L200, before turning their attention to the Mercedes-Benz X-Class.

The X-Class EXY Monster X Concept
The Carlex Design X-Class concept, internally referred to as the EXY Monster X, is a purpose-built track safety vehicle still in its design stages at the time of reveal. The entire body is constructed from carbon fiber, giving the truck both a significant weight reduction and a visually striking finish. Carlex lowered and widened the chassis considerably, extending the wheel arches over wide performance rims wrapped in Bridgestone Potenza rubber.

Safety Truck Details: Carbon, Yellow Accents and FIA Lighting
The load box is finished in an eye-popping yellow paint, a colour repeated across key details throughout the build: the winch hooks, the interior leather, and the roof-mounted safety lights. Front and rear winches are fitted to allow the truck to extract crashed race cars from the track, a practical function that reinforces its identity as a genuine safety vehicle rather than a pure show car. Ceramic-carbon disc brakes provide stopping power commensurate with high-speed safety interventions, and FIA-specification green-and-orange LED lighting distinguishes it immediately on circuit.

Carlex's Broader Custom Vehicle Range
The EXY Monster X is the most extreme expression of Carlex's pickup truck expertise, but it sits alongside a deep catalogue of custom work that spans nearly every vehicle category. Their approach, which they describe as a real-life "upgrade machine" for road cars, consistently delivers results that redefine the original vehicle's character entirely. Whether working with luxury SUVs or track-focused concepts, Carlex Design's output is unmistakably bold.
