CAPABILITY WITHOUT COMPROMISE

Sierra has built a reputation for incredible performance, especially when it comes to diesel heavy-duty trucks. 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 470 hp and 975 lb.-ft. of torque. And with closer gear spacing, 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

The dual-path intake system draws dense, cool air through both the hood scoop and the larger grille to enhance engine 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. This function can continue to idle the engine after extended and exhaustive periods of use, allowing for proper cooldown of vital underhood components.

POWERFUL PERFORMANCE

The 2024 Sierra 1500’s available second-generation 3.0L Duramax Turbo-Diesel engine was enhanced thanks to several key component upgrades including steel pistons with a revised combustion bowl, retuned turbo compressor, fuel injectors and improved temperature control features. 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.
