The 2025 Sierra 1500 offers three engine choices to match your driving priorities:

**TurboMax** powers the Pro, SLE, and Elevation trims. This efficient option delivers 310 horsepower and 430 lb-ft of torque and works in both 2WD and 4WD.

**5.3L V8** comes with the SLT trim, pairing with a 10-speed automatic. It's built for heavy trailering and towing with features like an automatic locking rear differential and available Max Trailering Package.

**3.0L Duramax Turbo-Diesel** powers the AT4, delivering impressive torque and efficiency alongside off-road suspension and terrain-ready tires.

Each engine is matched to the trim's intended purpose-economy and everyday capability, serious hauling, or off-road adventure. Our team at Markquart Motors can walk you through which engine suits your needs. Call **(715) 833-0444** or stop by to compare performance specs and fuel efficiency in person.
