Sierra has built a reputation for incredible performance, especially when it comes to diesel heavy-duty trucks. While the 2021 Sierra Heavy Duty offers powertrain advancements across the lineup, GMC’s legendary available Duramax diesel engine and Allison automatic transmission continue to offer the ultimate in pulling power. The 6.6L Duramax Turbo-Diesel V8 delivers an impressive 445 hp and 910 lb.-ft. of torque. And with closer gear spacing than before, the Allison 10-speed Automatic Transmission allows the engine to operate in an optimal range at all times with varying load and terrain conditions.
Engineers worked to make this already powerful engine perform more efficiently by increasing the cooling capacity by way of a larger radiator and fan, and improving the air induction system. The dual-path intake system draws dense, cool air through both the hood scoop and the larger grille to enhance its performance. And to help maintain optimal operating temperatures, Sierra Heavy Duty models equipped with the available Duramax Diesel feature an integrated engine after-run cooling function, which can continue to idle the engine after extended and exhaustive periods of use, allowing for proper cool-down of vital underhood components.

Best-in-class 277† available diesel horsepower outpaces rival diesel engines in capability. By reaching 95 percent of peak torque at a low 1,250 rpm and full torque from 1,500-3,000 rpm, the 3.0L Duramax® Turbo-Diesel I-6 engine provides excellent power and momentum without exerting the engine while taking on trails or roads in hilly or mountainous regions. GMC’s high standards for engineering excellence also meant taking this engine through millions of test miles not just for the Sierra 1500, but for the Yukon too. The vetting included observing how the Duramax 3.0L Turbo-Diesel would perform in extreme driving and adverse weather conditions.
GMC didn’t stop at just technology aimed at fuel delivery. The Duramax 3.0L Turbo-Diesel also has a lightweight all-aluminum engine block, which results in a 25 percent savings in mass over a comparable cast iron engine block. With the Duramax 3.0L Turbo-Diesel and Yukon, you’ll experience great power with a broad torque band, all without a compromise in efficiency.
Diesel engines are often marked by their distinctive rumbling sound; don’t expect it from Yukon’s Duramax 3.0L Turbo-Diesel. Featuring an inline 6-cylinder architecture, the engine gives you a quiet and smooth cabin experience. This engine configuration offers the ideal balance of primary and secondary forces so only two camshafts and their associated valvetrain components operate at one time. This not only eliminates the need for using balancing shafts, but minimizes friction.
