You have two excellent engine choices in the 2024 GMC Sierra 2500HD. The standard engine is a 6.6L V8 gas engine producing 410 horsepower and 464 lb-ft of torque. If you want even more power, the available 6.6L Duramax Turbo Diesel V8 delivers 470 horsepower. Both pair with an Allison 10-speed automatic transmission for smooth, responsive power delivery whether you're cruising the highway or tackling tough jobs. The diesel option is particularly popular for heavy-duty work and towing.
