The New 2025 GMC Sierra 1500

The 2025 Sierra 1500 offers four engines built for different priorities, from daily driving efficiency to serious towing muscle. The 2.7L TurboMax engine produces 310 horsepower and 430 lb-ft of torque, achieving up to 22 MPG highway in 2WD configurations and 18 MPG highway with AT4 4WD, making it a practical choice for balanced performance and economy.

The 5.3L V8 delivers 355 horsepower and 383 lb-ft of torque, offering classic V8 character with highway ratings reaching 21 MPG in 2WD models and 19 MPG in AT4 4WD setups. For drivers who want maximum capability, the 6.2L V8 pairs robust output—420 horsepower and 460 lb-ft of torque—with up to 20 MPG highway.

Meanwhile, the available 3.0L I-6 Duramax® diesel stands out for its exceptional efficiency, offering 305 horsepower and 495 lb-ft of torque, with up to 29 MPG highway in 2WD and 22 MPG highway even in AT4X trims. Whether fuel economy or raw strength is your priority, every Sierra powertrain is engineered to handle demanding jobs with confidence.

The Sierra 1500 is built to work hard. Max towing reaches 11,200 lbs. with the available 6.2L V8, while the 5.3L V8 supports up to 9,800 lbs. and the available 3.0L Duramax® diesel can tow up to 13,300 lbs. when properly equipped. For off-road capability, the AT4 and AT4X trims both offer a 2-inch factory lift, but the AT4X goes even further with Multimatic DSSV dampers, front and rear locking differentials, and 33" mud-terrain tires for serious trail confidence. Selectable drive modes let you fine-tune traction for towing, snow, or rough terrain, while Hill Descent Control and advanced trailer tech provide steady control on job sites or steep backroads near Chillicothe.

Start with the Pro and you get a clean, functional layout with durable materials and clever storage. Move up to SLE and Elevation, and you’ll find heated front seats, a 12.3" digital driver display, and optional leather-appointed seating in Jet Black or Dark Walnut Slate.

The SLT trim introduces more premium finishes and adds flexibility with multiple seating configurations and available tech like a power sunroof and center console wireless charging.

Things elevate quickly from there. AT4 models bring rugged refinement, with perforated leather seats, unique Kalahari accents, and rear under-seat storage. The AT4X interior is something else entirely: Obsidian Rush full-grain leather, real Vanta Ash wood trim, and massaging 16-way power seats that feel more luxury SUV than off-roader.

But the crown jewel is the Denali Ultimate. With its Alpine Umber leather, embossed topographic map details, and laser-etched wood accents, it doesn’t just impress—it stuns. There’s room to stretch out too: the Crew Cab configuration offers best-in-class front head- and legroom, turning even long hauls into quiet, comfortable rides.

The 2025 Sierra 1500 makes a bold impression with a strong, capable presence and distinctive styling across each trim. The Pro and SLE trims prioritize function, featuring clean lines and practical design elements that suit hardworking drivers. For those who want a more aggressive aesthetic, the Elevation trim introduces a monochromatic look with LED fog lamps and 20-inch gloss-black wheels that add attitude to the truck’s stance.

Off-road enthusiasts will appreciate the AT4, which is purpose-built for adventure with red tow hooks, a blacked-out grille, and rugged accents. Taking things further, the AT4X AEV Edition adds serious trail-ready gear, including steel bumpers, hot-stamped skid plates, and unique wheels designed to handle rough terrain. On the other end of the spectrum, the Denali trim brings a touch of sophistication with chrome accents and polished 20-inch wheels. At the top of the lineup, the Denali Ultimate adds exclusive Vader Chrome detailing, animated LED lighting, and eye-catching 22-inch Ultra-Bright wheels for a commanding luxury look.

No matter which trim you choose, every 2025 Sierra 1500 offers the available MultiPro™ Tailgate, giving you six smart configurations to make workdays more efficient or weekends more versatile. Exterior color options include Summit White, Cardinal Red, Onyx Black, Sterling Metallic, and Titanium Rush Metallic, with additional colors potentially available depending on your trim or through special order availability.

Even the most capable trucks need brains behind the brawn. The Sierra 1500 has both.

At the center of it all is the 13.4-inch premium touchscreen with Google built-in, standard on most trims. Pair that with a 12.3-inch digital cluster, and you’ve got a command center that feels intuitive, not overwhelming. Wireless Apple CarPlay® and Android Auto™ come standard on key trims, along with voice-activated tech and optional Bose® sound systems (7 to 12 speakers, depending on trim).

The tech highlight is Super Cruise®, available on Denali and standard on Denali Ultimate. It’s hands-free driving on compatible roads (yes, even while trailering) and offers automatic lane changes and intuitive alerts so you always stay in control.

The 2025 Sierra 1500 prioritizes driver confidence with a comprehensive suite of standard safety features. Across all trims, you'll find Automatic Emergency Braking, Forward Collision Alert, Lane Keep Assist, IntelliBeam® automatic high beams, and the Safety Alert Seat—all designed to help prevent collisions and enhance driver awareness.

As you move up the trim ladder, upgraded models add advanced technologies like Surround Vision, a Rear Camera Mirror, Adaptive Cruise Control, and more for an extra layer of protection and convenience.

A hardworking base trim with the TurboMax™ engine, 12 cargo tie-downs, and smart utility baked in.

Adds a premium touchscreen, heated seats, and digital gauges—perfect for buyers who want a balance of comfort and value.

Turns heads with monochrome styling and 20-inch wheels, while offering upgrades like leather and sunroof options.

Adds versatility and upscale materials, bridging the gap between everyday work and refined leisure.

Diesel-ready and off-road tuned with Rancho® shocks, skid plates, and bold exterior detailing.

The most rugged of the bunch, with DSSV dampers, front/rear e-lockers, massage seats, and AEV outfitting for serious off-grid performance.

Where premium meets power. Chrome-heavy, tech-laden, and available with diesel or gas V8.

The ultimate expression of Sierra luxury: Vader Chrome grille, Super Cruise®, Alpine Umber leather, and everything GMC knows about craftsmanship.
