GM is expanding the all-electric GMC Sierra EV lineup with the launch of the new entry-level 2026 GMC Sierra EV Elevation and 2026 GMC Sierra EV AT4 off-roader.

The AT4 will be the highest-riding Sierra, with 2 inches of additional lift thanks to lifted coil suspension and new 35-inch tires. AT4 models will also share a number of features with GMC’s Hummer EV, such as four-wheel steer, CrabWalk, and Terrain Mode. But the automaker stressed that the two EVs don’t actually share any physical components.

Twinned with the Chevrolet brand's Silverado EV, the Sierra EV will enter the 2026 model year this coming summer with more choice than ever before
