The 2025 GMC Sierra 1500 gives you four powerful engine choices to match your needs. The standard 2.7L TurboMax engine delivers 310 horsepower and 430 lb-ft of torque-impressive power right from the start. Want more? Choose the 5.3L EcoTec3 V8, the efficient 3.0L Duramax Turbo-Diesel I6, or the muscular 6.2L EcoTec3 V8. Every Sierra pairs its engine with an 8-speed automatic transmission and 2-speed AutoTrac transfer case for smooth, versatile driving. Upgrades like a 10-speed automatic and factory suspension lift are available too. Each engine balances power, capability, and fuel economy differently-so the right choice depends on your lifestyle. Call our team at (715) 833-0444 to discuss which engine fits you best.
