The 2025 GMC Sierra 1500 gives you four powerful engine options to match your needs. Start with the standard 2.7L Turbocharged Gas I4, delivering 310 horsepower and 430 lb-ft of torque-more standard torque than competing trucks. Step up to the 5.3L EcoTec3 V8 or 6.2L EcoTec3 V8 for increased power, or choose the 3.0L Duramax Turbo-Diesel I6 for efficiency and towing capability. Every Sierra pairs with an 8-speed automatic transmission and 2-speed AutoTrac transfer case for smooth shifts and versatile terrain control. Upgrades like a 10-speed automatic and factory-installed suspension lift are also available. Contact Markquart Motors at (715) 833-0444 to find your ideal Sierra 1500 configuration.
