Erick Stafford , with CARandDRIVER saidThe heavy duty pickup trucks that roam North America like overfed elk dont have any antlers, but rubbing up against a tree or two with the GMC Sierra 2500HD or 3500HD probably wont hurt it much either. Built to move the world, the heavy-duty Sierras are offered with either a 401-hp 6.6-liter V-8 and six-speed automatic transmission or a 445-hp 6.6-liter V-8 Duramax Diesel with 910 pound-feet of torque. The latter gets a 10-speed automatic and is the powertrain of choice for the Sierra 3500 if you plan on utilizing its 20,000 pounds of max conventional towing capability. Lets see an elk try that.
DENALI is the ultimate expression of Professional Grade. It also offers authentic heated and ventilated front seats and heated rear outboard seats, the Premium GMC Infotainment System with Navigation, Bose Premium Audio System, 8-inch Driver Information Center and wireless charging. This is also our most premium Sierra Denali interior ever with finely crafted materials and attention to every detail.
