The 2025 GMC Sierra HD comes in seven trims, each built for different priorities. **Pro** is your no-nonsense workhorse with a standard V8 gas engine. **SLE** adds modern comfort and Google infotainment. **SLT** brings leather and upscale touches. **AT4** includes factory lift, all-terrain tires, and 4WD for light trail work. **AT4X** (with optional AEV Edition) packs locking differentials and 35-inch tires for serious off-roading. **Denali** delivers luxury with heated/ventilated seats and premium materials. **Denali Ultimate** tops the lineup with the Duramax Diesel engine standard, massaging seats, and a head-up display.

Every Sierra HD roars with a standard 6.6L V8 (401 hp) or available Duramax Diesel (470 hp, 975 lb-ft torque). All trims feature GMC's 13.4-inch tablet touchscreen and MultiPro tailgate.
