The 2024 GMC Sierra 2500HD gives you two powerful engine choices. 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 pair with an Allison 10-speed automatic transmission for smooth, responsive power delivery whether you're cruising the highway or tackling tough jobs.
