The 2025 GMC Sierra 1500 offers four robust engine choices to match your needs. The standard 2.7L TurboMax four-cylinder delivers 310 horsepower and 430 lb-ft of torque-making it more powerful than base engines in competing trucks. You can also choose the 5.3L EcoTec3 V8, the powerful 6.2L EcoTec3 V8, or the efficient 3.0L Duramax Turbo-Diesel I6. Every engine pairs with an 8-speed automatic transmission and 2-speed AutoTrac transfer case for smooth, versatile driving. Upgrades like a 10-speed automatic and factory-installed suspension lift are available for even more tailored performance. Markquart Motors has new Sierra 1500s in stock-call (715) 833-0444 for details on current inventory and engine specs.
