French manufacturer Challenger has presented its 2027 collection with a new IRP 360 body structure that eliminates wooden battens. Composite elements are embedded in polyester sandwich panels insulated with XPS Styrofoam. The company claims improved insulation, weather resistance and longevity. The X series gains the X260 model, 6.55 m long with a large garage, replacing the X250. The profile range adds the 337 model, 7.19 m long with twin beds and a split bathroom, replacing the 317. Integral models receive a new front-end design due to ADAS (GSR2) requirements.
