The New 2025 GMC Sierra HD

The 2025 Sierra HD lineup offers unmatched strength and capability, led by two robust engine options designed for different demands. Standard on most trims is the 6.6L V8 gas engine, delivering 401 horsepower and 464 lb-ft of torque, paired with a 10-speed Allison® automatic transmission for seamless power delivery. For those who demand the ultimate in pulling strength, the available 6.6L Duramax® Turbo-Diesel V8 pushes 470 horsepower and a best-in-class 975 lb-ft of torque, ensuring confident towing under the heaviest loads.

The Sierra HD offers Rear-Wheel Drive (RWD) and available 4WD across trims, along with advanced Automatic Grade Braking, Tow/Haul mode, and a Digital Variable Steering Assist system that fine-tunes responsiveness based on load and speed. These refinements make every mile smoother—whether you’re towing through hills outside Urbana or navigating city streets with a full bed of materials.

When properly equipped, the Sierra 2500HD can tow up to 22,500 pounds, while the Sierra 3500HD with a dual rear wheel configuration can handle up to 36,000 pounds—one of the highest ratings in the segment. Payload capacity reaches 7,290 pounds, ensuring you can bring everything you need in one trip.

The 2025 Sierra HD isn’t just powerful—it’s built smart. With its independent front suspension, Hydraulic Body Mounts, and Trailer Side Blind Zone Alert, it delivers a composed ride without compromising its work-ready nature. Available Autotrac 4WD and an off-road suspension package provide added traction and stability for those who prefer the road less traveled.

The truck’s ProGrade Trailering System integrates up to 14 camera views, including Hitch View, Bed View, and Transparent Trailer View, making every connection effortless. Advanced trailering features like Adaptive Cruise Control with Trailering and Integrated Trailer Brake Controller further simplify towing—particularly valuable for Ohio contractors and boat owners hauling across Lakeview or Sidney.

The Sierra HD also introduces GM’s latest Trailer Tire Pressure and Temperature Monitoring System, a must-have for long-distance hauls. Combined with Hill Descent Control, Auto Electric Parking Brake, and Creeper Gear Mode, this heavy-duty truck delivers precision and power where it matters most.

Step inside the 2025 Sierra HD, and you’ll quickly notice how GMC has redefined comfort for heavy-duty truck drivers. The cabin balances rugged utility with luxurious design elements, creating an upscale environment for both work and recreation.

Across trims, the Sierra HD offers best-in-class front headroom and legroom, along with available 16-way power-adjustable front seats featuring massaging functions on higher trims. Premium materials include full-grain leather upholstery, authentic wood trim, and laser-etched metal accents, elevating the driving experience far beyond ordinary work trucks.

A 13.4-inch GMC Infotainment System sits at the center of the dash, supported by a 12.3-inch digital driver display and available 15-inch Head-Up Display—three dynamic screens providing seamless access to vital information. Wireless Apple CarPlay®, Android Auto™, Amazon Alexa, and Google built-in capabilities keep drivers connected, while the Bose® Premium Sound System ensures crystal-clear audio for every journey.

Whether you’re working near Urbana or hauling equipment through Bellefontaine, the Sierra HD’s quiet cabin, extensive storage, and ergonomic controls make long drives more comfortable than ever.

The 2025 GMC Sierra HD is as bold as it is functional. Its muscular profile, high-clearance stance, and signature C-shaped LED lighting project confidence from every angle. A redesigned front fascia with new grille textures and chrome or black accents (depending on trim) gives the Sierra HD a commanding presence, while newly styled 20-inch machined aluminum wheels add modern appeal.

Available power-retractable assist steps, LED perimeter bed lighting, and an AutoSense Power Tailgate enhance convenience on every job. The truck’s Durabed cargo box continues to lead the industry with 12 fixed tie-downs, CornerStep rear bumpers, and spray-on bedliner protection—making it both tough and practical.

The legendary MultiPro™ Tailgate returns, offering six unique functions for improved cargo access, loading flexibility, and even workstation usability. From hauling heavy lumber in Anna to organizing gear for a fishing trip near Lakeview, the MultiPro design adds everyday versatility to your workday.

Every 2025 GMC Sierra HD comes standard with the GMC Pro Safety Suite, a collection of advanced driver-assist technologies that protect you, your passengers, and your payload. This suite includes:

• Forward Collision Alert
• Front Pedestrian Braking
• Lane Departure Warning
• Automatic Emergency Braking
• Following Distance Indicator
• IntelliBeam® Auto High Beams

Available safety enhancements include Rear Cross Traffic Braking, Blind Zone Steering Assist, and Rear Pedestrian Alert. Drivers who frequently tow will appreciate the Transparent Trailer View and Adaptive Cruise Control with Trailering, features that simplify navigation and lane changes with heavy loads.

On select trims, Super Cruise™—GMC’s hands-free driver assistance system—is now available for the Sierra HD lineup, offering semi-autonomous driving on compatible roads. The system supports hands-free lane changes and even works while towing.

Technology extends beyond safety, too. The 2025 Sierra HD’s infotainment system integrates wireless phone charging, over-the-air software updates, and multiple USB-C ports, ensuring the cabin stays connected and convenient at all times.

The Pro serves as the foundation for the Sierra HD lineup, combining practicality with strength. It features the 6.6L V8 gas engine, vinyl flooring for easy cleanup, and a 7-inch touchscreen. Durable steel wheels and standard trailering equipment make it ideal for business owners seeking value and reliability.

The SLE trim upgrades to an 8-inch digital display, cloth seating, and chrome exterior accents. It introduces the MultiPro Tailgate and a more advanced infotainment interface.

Refined yet rugged, the SLT adds leather-appointed seating, heated front seats, power-folding mirrors, and a 10-speed Allison® transmission paired with the gas or diesel engine. A chrome grille and 18-inch polished wheels complete its upscale look.

The AT4 is the off-road enthusiast’s dream. Equipped with standard 4WD, hill descent control, skid plates, off-road suspension, and 18-inch machined aluminum wheels with all-terrain tires, it’s ready for any terrain Ohio throws your way. Unique Jet Black and Kalahari accents add a sporty edge inside the cabin.

Luxury meets muscle in the Denali trim. This version introduces the 15-inch Head-Up Display, Bose® 12-speaker Premium Audio, open-pore wood accents, and polished aluminum wheels. Chrome detailing throughout gives it the upscale look GMC is known for.

Sitting at the top of the range, the Denali Ultimate embodies GMC’s definition of perfection. It includes the 6.6L Duramax® Turbo-Diesel, Super Cruise™ hands-free technology, Vader Chrome exterior accents, 22-inch machined aluminum wheels, and full-grain leather seating with Alpine Umber stitching. This is the most advanced and luxurious heavy-duty truck GMC has ever built.
