The 2025 GMC Sierra 1500 gives you four powerful engine options to match your driving needs. The standard 2.7L TurboMax turbocharged 4-cylinder delivers 310 horsepower and 430 lb-ft of torque-an impressive combo that outperforms competing base engines. For V8 power, choose the 5.3L EcoTec3 V8 for balanced performance and efficiency, or step up to the 6.2L EcoTec3 V8 for serious hauling muscle. If you prefer diesel efficiency, the 3.0L Duramax Turbo-Diesel I6 offers excellent torque and fuel economy. Every Sierra pairs its engine with an 8-speed automatic transmission and a 2-speed AutoTrac transfer case for smooth shifting and terrain control. A 10-speed automatic transmission is available for enhanced performance.
