GM has opened a new design studio in Pasadena, and the GMC Hummer X concept is its first public result.
The headline is the body. GMC calls the approach “Flex Fab”: panels are 3D-printed on demand from metal or recycled plastic and clip on without adhesive. The company says 57% of the concept is built this way, which it pitches as near-limitless customization inside and out.
GMC showed two body styles. The SUV is 4,782 mm long on a 2,945 mm wheelbase, with 334 mm of ground clearance and 37” tires on 18” wheels. The Truck pickup stretches to 5,264 mm and a 3,318 mm wheelbase, with 316 mm of clearance and 35” tires on 22” wheels. Both ride on Multimatic dampers with underbody skid plates.
The concept’s powertrain is electric, with no details given. A production version would need a combustion or hybrid option - and there is a clear business case for one. Hummer EV sales fell 52.5% year-on-year in the first quarter of 2026, to 1,653 units, leaving the brand in need of a more affordable, non-electric model.
