The 2026 GMC Sierra 2500 HD brings strong performance to heavy-duty tasks. This workhorse offers a choice between two powerful engines. The 6.6-liter V8 gas engine delivers 401 horsepower, while the 6.6-liter Duramax turbodiesel produces an impressive 470 horsepower and 975 pound-feet of torque.
Both engines pair with a 10-speed automatic transmission that provides smooth power delivery. The Sierra 2500 HD offers 4-wheel-drive (4WD) and rear-wheel-drive (RWD) configurations across multiple cab and bed sizes. Standard features like the auto-locking rear differential and trailering package with 7-pin connector make hauling easier. The available Max Trailering Package adds even more capability with a reinforced frame, upgraded suspension, and gooseneck prep.
Additional capability features include multiple tire options up to LT305/70R18 for the AT4X trim, recovery hooks, and upgraded cooling systems. Whether you're working in Peru or heading out across Indiana, the Sierra 2500 HD has the strength for tough jobs.
