CAPABILITY WITHOUT COMPROMISE
Sierra has built a reputation for incredible performance, especially when it comes to diesel heavy-duty trucks. While the 2022 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.
OPTIMIZED ENGINE PERFORMANCE
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.

POWERFUL PERFORMANCE
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 3.0L Duramax Turbo-Diesel would perform in extreme driving and adverse weather conditions.
EXTRAORDINARY EFFICIENCY
GMC didn’t stop at just technology aimed at fuel delivery. The 3.0L Duramax 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 3.0L Duramax Turbo-Diesel and Yukon, you’ll experience great power with a broad torque band, all without a compromise in efficiency.
REMARKABLY QUIET
Diesel engines are often marked by their distinctive rumbling sound; don’t expect it from Yukon’s 3.0L Duramax 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.

DESIGNED FOR DURABILITY
A diesel engine was part of Canyon’s portfolio plan from the beginning. So you get no compromises with the Canyon diesel because the chassis, suspension and other elements of its architecture were engineered to include the 2.8L Duramax. This engine offers exceptional capability delivered with a confident feeling of control, advancing the Duramax brand’s legendary legacy of durability and reliability.
EFFICIENT AND REFINED
Two-wheel drive Canyon models equipped with the 2.8L Duramax Turbo-Diesel engine are EPA-rated at an impressive 30 MPG highway. Canyon is also equipped with a Centrifugal Pendulum Vibration Absorber (CPVA) in the torque converter that’s designed to control vibration and noise.
