The Sierra 1500 opens with the standard TurboMax engine, producing 310 horsepower and best-in-class standard torque of 430 pound-feet, paired with an 8-speed automatic transmission. Drivers looking for more muscle can opt for an available 5.3-liter V8 or the powerful 6.2-liter V8, both mated to a 10-speed automatic transmission. For those who prioritize efficiency alongside capability, the available Duramax 3.0-liter Turbo-Diesel engine delivers a maximum diesel towing capacity of up to 13,300 pounds when properly equipped. AT4 and AT4X trims add a factory-installed 2-inch suspension lift, Rancho monotube shocks or Multimatic DSSV dampers, and underbody skid plates for serious off-road performance.

Step inside the Sierra 1500 and you'll find a cabin crafted with genuine attention to detail. The truck offers best-in-class standard Crew Cab front head- and legroom, giving every occupant room to stretch out comfortably. Seating materials range from cloth on entry-level trims to available heated and ventilated perforated leather surfaces on mid-level trims, and full-grain leather with plaited contrast stitching on the Denali Ultimate. The Denali trim adds authentic wood accents and Forge perforated-leather seating surfaces, while the AT4X brings red double-needle stitching and ceramic white accents for a rugged-yet-refined look. Smart storage solutions throughout the cabin ensure there's always a place for your gear without sacrificing comfort.

The Sierra 1500 raises the bar for in-cab technology. A 13.4-inch diagonal multicolor touchscreen is available starting at the SLE trim, and the combined driver-focused digital displays span over 40 inches diagonal - the most in its class. Up to 14 available camera views help you navigate tight spaces and manage trailer connections with confidence. The available ProGrade Trailering System streamlines the hitching process with integrated tools designed to give you commanding control.

Google built-in compatibility and wireless charging round out a thoroughly connected driving experience.
