2026 GMC HUMMER EV: What's New, Specs & Features
Last updated August 4, 2026

About the 2026 GMC HUMMER EV
1st generation HUMMER EV; 2026 is a feature-and-software update year rather than a redesign. It is the 4th model year for the Pickup line and the 3rd for the SUV line.
GMC positions HUMMER EV as a bold electric off-road truck/SUV built around huge power, trail maneuverability, open-air roof panels, and premium cabin tech. It is less about efficiency or work-truck duty and more about presence, capability, and novelty. Compared with more practical electric trucks, HUMMER EV sells attitude: advanced off-road hardware, dramatic styling, and signature features like CrabWalk, King Crab, and Extract Mode, while still offering everyday comfort and large-screen tech.
The 2X delivers the main HUMMER EV experience with two motors, four-wheel steering, removable roof panels, adaptive air suspension, and a 13.4-inch touchscreen. The 3X adds a more powerful three-motor setup while keeping the same trail-focused steering features, open-air roof, and large-screen cabin.
