The 2024 GMC Sierra 2500HD offers two powerful engine choices to suit your needs. The standard option is a robust 6.6L V8 gas engine delivering 410 horsepower and 464 lb-ft of torque. If you want maximum capability, the available 6.6L Duramax Turbo Diesel V8 engine pumps out 470 horsepower.

Both engines pair with an Allison 10-speed automatic transmission for smooth, responsive power delivery on highways and tough jobs alike. The diesel option is particularly engineered for demanding workloads and heavy hauling, giving you flexibility to choose the right fit for your lifestyle and work requirements.
