2025 GMC Sierra 1500

At Holloway GMC, we take pride in offering the 2025 GMC Sierra 1500—an audacious full-size pickup engineered with intelligence, brawn, and refinement. Purpose-built for drivers in Portsmouth, NH who expect more than just utility, the Sierra 1500 is a statement of modern capability.

Trim Levels (Exterior)

The 2025 Sierra 1500 offers a visually arresting array of trims: Pro, SLE, Elevation, SLT, AT4, Denali, AT4X, and Denali Ultimate. Each presents a distinct exterior personality. The Pro keeps it foundational—rugged, assertive, no-frills. Elevation throws in monochromatic accents, dark finishes, and bold 20" wheels that elevate street presence. AT4 and AT4X, adorned with vertical red recovery hooks and off-road armor, dominate trail aesthetics. Denali? A chromed, chiseled monument on wheels, crowned by a signature grille and intricate Vader chrome finishes. The Denali Ultimate? Satin-chrome grille, 22" wheels, and a silhouette that oozes dominance. All trims benefit from C-shaped LED headlamps, aggressive stance geometry, and the MultiPro™ Tailgate—six functions, endless utility.

Engine (Power)

Sierra’s heartbeat is choice. The 2.7L TurboMax™ engine punches out 310 horsepower and 430 lb-ft of torque—effortlessly. Step up to the 5.3L V8, and you'll feel 355 hp awaken the road beneath. The 6.2L V8, mated to a 10-speed auto, delivers a growl-backed 420 hp and 460 lb-ft of torque. Diesel seekers aren't left out—the 3.0L Duramax® Turbo-Diesel I6 balances 305 hp and 495 lb-ft of torque with smooth, whisper-quiet finesse. Each engine option integrates Direct Injection and Active Fuel Management, offering potency without sacrificing efficiency.

Performance

The Sierra 1500 doesn't just move—it conquers. With available Adaptive Ride Control and segment-first CarbonPro™ composite bed technology, the chassis absorbs terrain shocks with grace. Four-wheel drive, selectable drive modes, and off-road-tuned suspensions in AT4 trims unleash total command across gravel, snow, or asphalt. Maximum towing capacity reaches a formidable 13,300 lbs, made manageable by advanced trailering tech: in-vehicle trailering app, hitch guidance with hitch view, and multiple camera angles. Braking, balance, and traction are never an afterthought here—they’re engineered precision.

Interior

Cabin design bridges the industrial and the artisanal. Inside the Denali Ultimate, full-grain leather, wood accents, and microsuede headliners redefine pickup luxury. The available 13.4" diagonal GMC Premium Infotainment System, partnered with a 12.3" digital Driver Information Center and a 15" multicolor Head-Up Display— deliver real-time clarity. Wireless Apple CarPlay®, Android Auto™, and built-in Google integration provide seamless connectivity. Heated and ventilated seats, massaging front seating (on select trims), and Bose® Premium Series audio create an acoustic and ergonomic sanctuary.

Safety Features

Confidence is not optional. Sierra 1500 comes fortified with GMC Pro Safety: Automatic Emergency Braking, Forward Collision Alert, Lane Keep Assist with Lane Departure Warning, Front Pedestrian Braking, and IntelliBeam auto high beams. The Denali Ultimate adds Super Cruise™—hands-free driver assistance on compatible roads—plus Trailer Side Blind Zone Alert and HD Surround Vision. Even low-speed maneuvers become sophisticated operations with features like Front and Rear Park Assist and the Safety Alert Seat. Every trim asserts a commitment to occupant and pedestrian safety without compromise.
