General Motors hasn’t fielded a true rival to the Jeep Wrangler since the Chevrolet K5 Blazer and GMC Jimmy rode off into the sunset back in the 1990s. Ford found itself in the same position for years, right up until the modern Ford Bronco arrived earlier this decade. The gamble paid off as the Bronco has proven to be a huge hit, with Ford moving a record 146,007 units in the US in 2025 alone – and the Wrangler is an even bigger hitter.GMCIt all proves that America’s appetite for rugged, retro-flavored off-roaders is stronger than ever, but GM has seemingly chosen to sit this battle out - up until now: Enter the GMC Hummer X, a wild new concept that reimagines the Wrangler-and-Bronco formula for the EV era. Think removable panels, chunky off-road hardware, silent propulsion, and enough attitude to make a Rubicon look positively sensible."The HUMMER X concept is envisioned to be a capable rock crawler designed and engineered as a modular platform, and is built around four pillars: reconfigurability, capability, community, and sustainability."- General Motors Honey, I Shrunk The Hummer EV GMC Like the larger GMC Hummer EV lineup, the Hummer X concept comes in both SUV and pickup body styles, and the family resemblance is immediate. The upright proportions, squared-off surfacing, and wide stance all echo GMC’s existing electric flagship. In pickup form, the Hummer X Truck Concept is clearly aimed at the Jeep Gladiator, with the rear three-quarter view looking like an almost exact match.The dimensions reinforce the intent. The Hummer X Truck Concept comes in roughly 11 inches shorter than the Gladiator, slotting it firmly into the midsize off-road pickup class rather than the oversized EV territory GMC currently occupies. The SUV follows a similar logic, as it lands almost exactly on top of the four-door Wrangler's footprint and sits just about an inch shy of the Ford Bronco four-door. It's also just a couple of inches longer than the upcoming Rivian R2.Where the Hummer X also clearly departs from the Hummer EV is in its emphasis on reconfigurability. GMC describes it as a builder-maker vehicle, aimed at owners who don’t just drive, but actively modify, upgrade, and personalize their rigs. Helping in this regard is a production process GM calls FLEX FAB, which, instead of traditional stamping dies, uses low-volume, on-demand processes like 3D printing.GMC Hummer X Concept InteriorIt opens the door to a much wider array of configurations. This ethos carries into the cabin, too, where stackable digital displays let drivers tailor the interface to the task at hand. Built For Rock Climbing GMC Hummer X SUV Concept Rear 3/4 ViewOn paper, the Hummer X specs point to serious off-road intent. The SUV concept rides on 37-inch Goodyear tires, while the truck uses 35-inch rubber, both mounted on beadlock-capable wheels (18-inchers on the SUV and 22-inchers on the pickup). There’s also heavy underbody protection – a must for the battery – along with Multimatic dampers, which are the same position-sensitive spool-valve design used on off-road-ready GM vehicles like GMC’s AT4X-badged pickups and Chevy’s ZR2 line.Ground clearance is substantial as well, and is backed by strong approach, departure, and breakover angles, giving the SUV in particular a highly favorable stance for steep ascents and tight breakovers that would challenge more conventional midsize off-roaders. Add removable fender flares and the low center of gravity and instantaneous torque of an EV powertrain, and the result should be a vehicle that can effortlessly handle rough terrain. A drone is even included for scouting the line ahead. The Road Ahead Capture 2 (1)For now, though, there’s no path to production. The company says that, while it is not intended for production at this time, it's a "testbed for new technologies, new aesthetics and new ways to build community around adventure." Thus, there are no details on platform architecture or powertrain specifications, just a design brief built around a modular platform that formed part of a company event.The Hummer X duo was shown as part of a broader event celebrating the reopening of GM’s Advanced Design Pasadena studio in California, which was damaged by a fire last year. Still, given the strong and growing demand for rugged, adventure-focused off-roaders, there’s at least a plausible path forward, especially if the concepts land well with enthusiasts.Sources: GMC
