Hummer X Concept Takes Aim at Bronco and Wrangler with Radical Recyclable Tech

GMC has rolled out the Hummer X, a pair of non-production concept vehicles—a truck and an SUV—designed as a rolling lab for sustainability and modularity. The Hummer X ditches adhesives in favor of “mono-materials” that snap together and can be fully disassembled for part swapping and recycling, aligning with GMC’s vision of a circular economy. The concepts also showcase “Flex Fab,” a 3D metal-printing process that accounts for 57% of both vehicles, enabling flat-top designs, rounded edges, laser-welded seams, and exposed bolts.

Both feature Multimatic shocks, underbody armor, removable fenders, and beadlock wheels shod in Goodyear rubber—37-inch tires on the SUV and 35-inch on the truck. The SUV measures 188.3″ long, 80″ wide, and 72.9″ tall on a 116″ wheelbase, with 13.2″ of ground clearance, making it smaller but taller-clearance than the production Hummer EV SUV (206.7″ long, 86.46″ wide, 77.8″ tall, 10.2″ clearance). The truck is 207.3″ long with a 12.5″ ground clearance, sitting lower than the Hummer EV truck (216.8″ long, 79.1″ tall, 10.2″ clearance) but retaining a wheelbase only six inches shorter.

Inside, the Hummer X flips the script with “stackable displays”—the dashboard lined with seven screens—allowing drivers to reconfigure the cabin layout. The concepts debuted to celebrate the opening of GM’s new design studio in Pasadena, California, developed in collaboration with GM Advanced Engineering, Advanced Manufacturing, and the new studio. While GMC confirmed no plans to build the Hummer X, Motor1 suggests some of its radical features could migrate to future Hummer EV updates or other models.
