Overview

Like all Sierras, the 2500HD is available in a wide array of bed sizes, wheelbases, drive types and cab sizes, as well as a variety of trim levels. The Sierra HD comes in one of several different body styles with long and short bed options. However, despite this complexity there are only two available engines, both V8 units displacing 6.6 liters. The gasoline option is paired to a 6-speed automatic and makes 401 horsepower and 464 lb-ft of torque. The more expensive diesel engine is aided by a turbocharger and makes 445 horsepower and a massive 910 lb-ft of torque. For 2021, the Sierra HD lineup is introduced with more wheel options, more exterior color choices and some new technology as standard on various trims.
