2025 GMC Sierra 1500

Eight trim levels define the 2025 GMC Sierra 1500’s outer persona—each a unique interpretation of brawn and elegance. The Pro stands unapologetically functional, while the SLE injects elevated styling with bold C-shaped LED headlamps and chromed accents. The Elevation trim darkens the mood with monochromatic finishes and 20" Gloss-Black aluminum wheels. Move upward to the SLT, where satin-chrome mirror caps and polished grille textures take center stage. The AT4, built for trails, wears red vertical recovery hooks, a factory-installed 2" suspension lift, and Goodyear® Wrangler DuraTrac® tires. The Denali and Denali Ultimate sit in a league of their own—gleaming with Vader Chrome finishes and signature animated LED lighting. No matter the trim, presence is undeniable.

Under the hood, the Sierra 1500 offers a quartet of powerhouses. The base 2.7L TurboMax™ churns out 310 hp and 430 lb-ft of torque—quick off the line and confidently efficient. Step up to the venerable 5.3L EcoTec3 V8 for a rich 355 hp. The 6.2L V8, exclusive to upper trims, unleashes 420 hp and 460 lb-ft of torque, mated to a ten-speed automatic that shifts like silk. Diesel devotees will gravitate toward the 3.0L Duramax® Turbo-Diesel I6. With 305 hp and 495 lb-ft of low-end grunt, it hauls like a beast but sips like a commuter. Each engine is engineered with precision, offering a fusion of thrust and endurance that adapts to your terrain and temperament.

This is not a paper-tiger pickup. Max towing capacity reaches up to 13,200 lbs with the right configuration—dominating its class. Adaptive Ride Control (standard on Denali Ultimate) reads the road and adjusts damping in real-time, smoothing potholes and rough terrain into afterthoughts. Hill Descent Control, off-road optimized suspension, and selectable drive modes sharpen the Sierra’s off-pavement prowess. Fuel economy remains practical, ranging from 21 MPG city / 23 MPG highway on the Duramax diesel, to 17 MPG city / 20 MPG highway with the 6.2L V8. Whether it’s the daily grind or weekend escape, the Sierra doesn’t flinch.

Inside, the 2025 Sierra 1500 transforms from rugged to refined. Pro and SLE trims feature durable surfaces with functional ergonomics. In contrast, the Denali trims elevate everything—authentic open-pore wood, etched stainless accents, and 16-way power massaging front seats. It’s a command center wrapped in leather and stitched sophistication. A 13.4" diagonal GMC Premium Infotainment System anchors the dash, paired with Google built-in and a vivid 12.3" Driver Information Center. Wireless Android Auto™ and Apple CarPlay® are standard across the lineup. Space is never at a premium; crew cab configurations offer rear legroom that rivals luxury SUVs, and under-seat storage maximizes cargo flexibility. Noise-canceling tech hushes the cabin, isolating you in quiet command.

No compromises here. Sierra 1500 comes standard with GMC Pro Safety: Automatic Emergency Braking, Lane Keep Assist with Lane Departure Warning, Front Pedestrian Braking, and IntelliBeam® auto high beams. More advanced protections—like the available Super Cruise™ hands-free driving system with automatic lane change and trailering assist—push boundaries of what a full-size truck can do. The Trailer Side Blind Zone Alert and HD Surround Vision system reimagine trailering with 14 available camera views, reducing blind spots and boosting confidence in tight corridors. Forward Collision Alert, Rear Cross Traffic Braking, and Front Park Assist add layers of digital intuition that make maneuvering seamless.
