General Motors has revealed the GMC HUMMER X concepts, a pair of mid-size electric vehicles in pickup and SUV form developed as a testbed for technology and design. The concept is not intended for production.
The HUMMER X is built on a modular platform and uses a manufacturing approach GM calls FLEX FAB, which allows small-batch production without specialised stamping tools. Multiple body designs can be produced from the same machines. Externally, the concept is characterised by a flat-topped silhouette, radiused edges, laser-welded seams and visible precision bolts.
Inside, stackable displays let drivers configure the digital interface for different uses, whether rock crawling, trail running or highway travel. The SUV runs 37-inch Goodyear tyres on 18-inch alloys and sits on 334mm of ground clearance, with approach and departure angles of 44 and 46 degrees. The pickup runs 35-inch Goodyears on 22-inch alloys, with 317mm of ground clearance and a 41.5-degree approach angle.

GM has also developed a connected app suite called HUMMER HUB that links to the vehicle before, during and after trips. It includes a scout drone that flies ahead on trails, feeds real-time terrain data back to the vehicle, and docks when not in use.
Construction uses mono-material components, snap-fit fasteners in place of adhesives, and parts designed for disassembly and recirculation. Seatbacks, headrest backs and instrument panel ends are made from recycled car fascias.
The HUMMER X concepts were unveiled alongside the opening of GM’s new Advanced Design studio in Pasadena, developed through collaboration between GM Advanced Engineering, Advanced Manufacturing and the Advanced Design team.
