The 2024 GMC Sierra 2500HD offers two impressive engine choices. The standard 6.6L V8 gas engine delivers 410 horsepower and 464 lb-ft of torque. If you need more power, the available 6.6L Duramax turbocharged diesel V8 engine bumps output to 470 horsepower.

Both engines pair with an Allison 10-speed automatic transmission for smooth, responsive power whether you're highway cruising or tackling heavy-duty work. The choice depends on your driving style and fuel preferences. Markquart Motors can walk you through both options-call (715) 833-0444 to discuss which engine is right for you, or visit our lot in Chippewa Falls for a closer look.
