The 2025 GMC Sierra 1500 gives you four robust engine choices to match your driving needs. The standard 2.7L TurboMax I4 delivers 310 horsepower and 430 lb-ft of torque-the most torque in its class. You can also select the 5.3L EcoTec3 V8, 6.2L EcoTec3 V8, or the 3.0L Duramax Turbo-Diesel I6 for maximum capability.

Each engine pairs with an 8-speed automatic transmission and 2-speed AutoTrac transfer case for smooth shifting and versatile terrain control. Looking for even more capability? Available upgrades include a 10-speed automatic transmission and factory-installed 2-inch suspension lift.

Choosing the right powertrain depends on your hauling and towing needs. Contact Markquart Motors at (715) 833-0444 to discuss which Sierra 1500 engine is perfect for you, or browse our current inventory online.
