Engine and Performance
The 2026 GMC Sierra 3500HD boasts an impressive range of engine options tailored to meet the demands of heavy-duty work and off-road adventures. At the heart of the Sierra 3500HD’s powertrain lies a choice of two potent diesel engines and one robust gasoline engine.
The base engine is a 6.6-liter Duramax V8 turbo-diesel, producing a remarkable 445 horsepower and an earth-shattering 910 lb-ft of torque. This formidable powerplant provides ample grunt for hauling heavy loads and tackling challenging terrains. For those seeking even greater pulling power, the Duramax V8 can be upgraded to deliver a monstrous 475 horsepower and a mind-boggling 1,230 lb-ft of torque. This monstrous torque output enables the Sierra 3500HD to tow up to an astounding 36,000 pounds and carry a payload of up to 7,442 pounds.
Alternatively, customers can opt for the 6.6-liter gasoline V8 engine, which generates a substantial 401 horsepower and 464 lb-ft of torque. While not as torquey as its diesel counterparts, the gasoline V8 offers a smoother and quieter driving experience.
All engines are mated to a robust Allison 10-speed automatic transmission, renowned for its seamless gear changes and durability. The transmission features optimized gear ratios for both on-road and off-road scenarios, ensuring efficient power delivery and smooth shifting under all conditions.
Regarding fuel efficiency, the Duramax diesel engines offer impressive ratings for a heavy-duty truck. The base Duramax V8 achieves an EPA-estimated 19 mpg in the city and 26 mpg on the highway, while the upgraded Duramax V8 returns 17 mpg in the city and 24 mpg on the highway. The gasoline V8 engine delivers a respectable 16 mpg in the city and 20 mpg on the highway.
The Sierra 3500HD also incorporates several fuel-saving technologies to enhance its efficiency further.
