GMC is expanding the Sierra EV lineup for the 2026 model year with AT4 and Elevation trims and 3 available battery sizes. The new starting price is $64,495

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

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.
