Power Meets Precision: 2025 GMC Sierra 2500HD SLE in Black

Discover Why Cornwall’s Heavy-Duty Drivers Trust the Sierra 2500HD

If you’re in the market for a powerful, reliable, and tech-savvy truck that can handle work and play with equal confidence, the 2025 GMC Sierra 2500HD SLE is your perfect match. With its commanding 6.6L Duramax Turbo-Diesel V8 engine, 10-speed automatic transmission, and rugged 4WD capability, this truck is built to conquer the toughest terrain across Cornwall, Ingleside, Morrisburg, and the United Counties of Stormont, Dundas and Glengarry. Whether you're towing equipment to a job site or heading out on a weekend escape, the Sierra 2500HD delivers uncompromising performance backed by top-tier technology.


Rugged Good Looks with Purposeful Design

From the job site to the campsite, the black exterior of the Sierra 2500HD SLE makes a bold impression. Chrome accents on the front bumper and grille elevate its rugged persona, while the LED headlamps and daytime running lamps provide crisp visibility in all conditions. The 17-inch machined aluminum wheels and trailering mirrors with heated upper glass ensure form meets function. And when you’re loading up gear in the back, the EZ Lift Tailgate with power lock and release is there to make the job easier.


Comfort and Control Inside the Cabin

Step inside the spacious and intelligently designed cabin and discover a workspace that doubles as a sanctuary. The cloth seat upholstery offers durability and comfort, while the wrapped steering wheel and strategically placed controls put everything within easy reach. The 60/40 split-folding rear bench provides versatile storage options, and with 120V power outlets in both the cab and bed, you’re always plugged in and powered up for work—or play.


Safety and Technology That Work Hard for You

The 2025 Sierra 2500HD SLE is equipped with the latest safety tech to keep you and your passengers protected across every kilometre. Forward Collision Alert, Lane Departure Warning, and Automatic Emergency Braking all come standard to enhance peace of mind on Cornwall’s busy roads. Meanwhile, the StabiliTrak electronic stability control system ensures confident handling, and the rear vision camera makes backing up this heavy-duty truck a breeze.


Outshining the Competition in Every Category

Looking at other heavy-duty trucks like the Ford F-250 XLT or the Ram 2500 Big Horn? The Sierra 2500HD SLE stands tall with its cutting-edge 13.4-inch infotainment display powered by Google built-in, 12.3-inch digital driver information centre, and seamless smartphone integration via Apple CarPlay® and Android Auto™. Add SiriusXM® with 360L and proximity keyless entry, and you’ve got a truck that’s not only smarter—it’s just plain better for everyday convenience in Eastern Ontario.
