The Diesel
What the 6.6L Duramax Adds
The available 6.6L Duramax turbo-diesel V8 makes 470 horsepower and 975 lb-ft of torque, paired with the heavy-duty Allison-built 10-speed automatic. That torque is the reason to buy diesel: properly equipped with the Max Trailering Package, the 2500HD is rated up to 20,000 pounds on a conventional hitch and 22,050 pounds on a gooseneck or fifth-wheel, with a 30,000-pound GCWR. The standard 6.6L gas V8 makes 401 horsepower and 464 lb-ft and tows up to 16,000 pounds conventional, which is plenty for many buyers, but if you regularly pull a loaded gooseneck, a fifth-wheel RV, or heavy equipment, the Duramax is the engine that does it without strain and holds a steadier speed on grades. For the full breakdown by cab and hitch, see the towing and payload guide.
