SIERRA EV AT4
OFF—ROAD CAPABILITY, TECHNOLOGY AND STYLE

The 2026 Sierra EV AT41 brings the AT4 lineup’s signature combination of off-road capability, technology and style to an electric pickup. An additional 2” of ground clearance and 35” all-terrain tires enhance both capability and appearance.

Standard 4-Wheel Steer with CrabWalk®2 allows the rear wheels to turn independently from the front wheels, helping with maneuverability (compared to a full-size truck with two-wheel steering) and allowing the Sierra EV to move diagonally at low speeds. The innovative 2-motor e4WD system delivers power to all four wheels simultaneously, automatically adjusting to driving conditions.

The AT4 also includes selectable drive modes, including the trim-exclusive Terrain Mode. This mode combines Sierra EV’s proven off-road design and engineering with software advancements to help deliver outstanding capability. A 14” diagonal Head-Up Display and standard Super Cruise® hands-free driver assistance technology with 3-year OnStar One Super Cruise plan3 help drivers feel in control.

Key available features include:

  • 2026 Sierra EV Max Range battery offering up to a GM-estimated 478 miles of range4
  • MultiPro MidGate, which offers 10' 10" of cargo length when used with the MultiPro Tailgate lowered with load stop in place, folded rear seats and removable back glass window
