The 2025 GMC Sierra HD roars with choice-whether you're hauling heavy loads or towing across terrain, this truck delivers brawn and brains. You get two engine powerhouses: a standard 6.6L V8 gas (401 hp, 464 lb-ft) and an available Duramax 6.6L Turbo-Diesel V8 (470 hp, 975 lb-ft of torque).

Every trim features GMC's 13.4-inch tablet-style touchscreen, 12.3-inch digital driver display, and innovative MultiPro tailgate. Choose your personality: Pro for work focus, SLE for balance, SLT for polish, AT4 for trails, AT4X for extreme off-road, Denali for luxury, or Denali Ultimate for peak refinement.
