The 2025 GMC Sierra 1500 offers four distinct engine choices to match your driving needs. The standard 2.7L TurboMax engine delivers 310 horsepower and 430 lb-ft of torque-impressive power for the base model. For more capability, choose the 5.3L EcoTec3 V8 gas engine or step up to the 6.2L EcoTec3 V8 for maximum performance. If fuel efficiency and diesel capability matter to you, the 3.0L Duramax Turbo-Diesel engine is available. Every Sierra 1500 pairs its engine with an 8-speed automatic transmission and a 2-speed AutoTrac transfer case for smooth, versatile driving. Upgrades like a 10-speed automatic and factory-installed suspension lift are also available.
