2025 GMC Sierra 1500

The Sierra 1500 arrives in 8 trims—Pro, SLE, Elevation, SLT, AT4, AT4X, Denali, and Denali Ultimate—each designed to speak to a different type of driver. The entry-level Pro offers a straightforward, work-ready design that sets a foundation of dependability. Moving upward, SLE and SLT trims add chrome details and exterior refinements, making them ideal for drivers seeking functionality with elevated curb appeal. The Elevation trim introduces a bold presence, distinguished by its gloss-black mesh grille and 20-inch black alloy wheels that turn heads in downtown Gilbert as easily as they command attention on desert roads. For off-road enthusiasts, the AT4 and AT4X trims deliver factory-engineered ruggedness: lifted suspension, underbody skid plates, and Rancho® shocks, ensuring confidence on trails near Tonto National Forest. At the pinnacle, the Denali and Denali Ultimate embody GMC’s luxury ethos. With a signature Vader Chrome grille, 22-inch multi-spoke wheels, and power-retractable assist steps, these trims combine elegance with practicality. Every Sierra is finished with meticulous detail, including LED lighting options and the six-function MultiPro Tailgate, setting it apart in both utility and design.

The TurboMax™ engine offers up 310 hp with a Best-in-Class 430 lbs.-ft. of torque for reliable, powerful everyday performance. For more power, the 5.3L V8 engine delivers 355 hp and 383 lbs.-ft. of torque, offering excellent towing capability and performance, but the 6.2L V8 engine takes it to the next level, generating a massive 420 hp and 460 lbs.-ft. of torque. This V8 powerhouse is the ideal choice for those needing top-tier power and hauling capacity. Additionally, the 3.0L Duramax® Turbo-Diesel engine provides a class-leading 495 lbs.-ft. of low-end torque, offering an impressive combination of towing power and fuel efficiency for those who need both.

Designed with a suspension that balances road comfort with toughness, the truck glides across Gilbert’s streets while remaining confident on unpaved roads. The AT4X, equipped with Multimatic® DSSV dampers and locking differentials, is trail-ready right from the showroom floor. This trim, in particular, caters to adventure seekers who demand precision handling on steep, uneven desert trails. Towing remains a central strength of the Sierra 1500, with a maximum capacity of up to 13,200 pounds. GMC’s ProGrade™ Trailering System enhances confidence, offering up to 14 available camera views to simplify everything from hitching up in a crowded Gilbert driveway to reversing with precision on a dusty worksite.

The cabin prioritizes space and comfort, with crew cab configurations offering generous legroom for long drives across the Valley. In the Denali and Denali Ultimate trims, leather-appointed seating and authentic wood accents elevate the interior into the realm of luxury sedans, while still delivering the durability expected of a full-size truck. The AT4X blends rugged utility with indulgence, offering 16-way power-adjustable seats with heating, ventilation, and even massage—perfect for unwinding after a day of hauling or off-road exploring. A 13.4-inch touchscreen infotainment system provides seamless access to wireless Apple CarPlay®, Android Auto™, and intuitive navigation, ensuring drivers remain connected across Arizona’s expansive roadways.

Safety is central to the Sierra 1500’s appeal, with GMC equipping it with a comprehensive suite of driver-assistance technologies. Standard features such as Forward Collision Alert, Automatic Emergency Braking, and Lane Keep Assist provide essential coverage for daily commuting. Higher trims introduce advanced systems like Adaptive Cruise Control, Rear Cross Traffic Alert, and Park Assist, offering peace of mind during longer highway drives or maneuvering through Gilbert’s busy shopping centers. When towing, the available ProGrade™ Trailering System enhances safety further, integrating tools such as hitch guidance and trailer light checks, turning every journey into a more secure and confident experience.
