You have two powerful engine choices for the 2024 GMC Sierra 2500HD. The standard 6.6L V8 gas engine delivers 410 horsepower and 464 lb-ft of torque. If you want even more power, the available 6.6L Duramax Turbo Diesel V8 engine produces 470 horsepower. Both engines pair with an Allison 10-speed automatic transmission for smooth, responsive power whether you're cruising the highway or tackling demanding work. The 2024 model year features an upgraded, more powerful Duramax diesel-a real step up from previous years. Want to compare specs or take a test drive?
