While the Sierra 2500HD offers endless customizable options, GMC makes it easy with six trim level options that allow you to quickly tailor the pickup to meet you exact specifications. That includes a brand new Denali Ultimate trim that has been introduced as a part of the redesign. Keeping with Denali tradition, the new trim introduces premium touches inside and out, including chrome accents on the grille, as well as full-grain leather seating, wood accents and a 12-speaker Bose sound system inside.

Standard equipment under the hood is a 6.6-liter, naturally-aspirated (gas-powered) V8 that is now bolted to a ride-smoothing, Allison 10-speed automatic transmission that further optimizes power, torque and efficiency. At its peak, the gas V8 tops out at 401 horsepower and 464 lb-ft of torque.

If you’re looking for a bit more oomph, it’s the enhanced diesel engine that will tickle your fancy. In terms of size, its liters match that of the gas-powered engine, but the upgraded turbocharger helps to increase low-end torque over the previous model, and also contributes to increased power and torque over the entire operating speed range. Total torque of the diesel powertrain is double that of the gas V8 with an output of 975 lb-ft. Horsepower also sees a boost with an output that tops out at 470 hp. The power output is enough to give the crew cab 2500HD a class-leading, 22,070-pound towing capacity.
