The new 2026 GMC Sierra EV AT4 is the rugged adventure variant, engineered for serious off-road capability. It features massive 35-inch all-terrain tires, a lifted suspension system that adds two extra inches of ground clearance, and the innovative **"CrabWalk" four-wheel steering** system borrowed from the Hummer EV-allowing diagonal movement in tight spaces.

This makes the AT4 perfect for trails, campsites, and challenging terrain while maintaining all the Sierra EV's impressive electric performance: 760 horsepower, 785 lb-ft of torque, and up to 478 miles of range. You get luxury and capability combined.
