The EV market has flat-lined, but GM's luxury truck division sees opportunity. The $64,495 Elevation trim bookends the $92k Denali.

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

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.
