The 2026 GMC Sierra 2500HD arrives at McNaught Buick GMC equipped to handle the diverse hauling requirements found across Manitoba’s commercial and agricultural sectors.

This heavy-duty pickup provides the towing ratings, payload figures, and interior refinement that professionals in the Winnipeg region have come to expect from the Sierra nameplate. The HD platform includes both 2500HD and 3500HD variants with numerous cab, bed, and drivetrain permutations. With the available Duramax diesel engine and Max Trailering Package fitted, conventional towing reaches 9,072 kg (20,000 lbs). The 2026 model year brings two additional exterior colours—Glacier White Tricoat and Coastal Dune—while expanding MultiPro Tailgate availability to the SLT trim for added functionality.

Technology

An available 13.4-inch diagonal touchscreen anchors the infotainment experience, mounted in landscape orientation at dashboard centre. Split-screen capability allows two applications to run simultaneously—navigation on one side while music controls occupy the other. Google built-in arrives standard on all trims except Pro, enabling voice commands, integrated mapping, and app connectivity when paired with an active data subscription. Wireless Apple CarPlay and Android Auto integration keeps smartphones connected without physical cables. The available 15-inch diagonal head-up display and 12.3-inch digital gauge cluster add to the visual information array, totalling over 40 inches of screen real estate.

Towing assistance technology reaches sophisticated levels via the ProGrade Trailering System, which provides up to 14 camera perspectives. Enhanced Transparent Trailer View accommodates gooseneck and fifth-wheel configurations, combining truck and trailer camera feeds to show the area behind as though looking through the trailer. Trailer Side Blind Zone Alert extends awareness to cover zones alongside attached trailers. Available Adaptive Cruise Control with Trailering maintains set speeds while compensating for trailer drag and longer braking requirements. Standard active safety content includes Forward Collision Alert, Automatic Emergency Braking, Lane Departure Warning, and Front Pedestrian Braking.

Exterior

The Sierra 2500HD establishes its presence through bold front-end styling that varies across the trim hierarchy. Each grade receives unique grille patterns and fascia treatments, creating distinct visual identities from the work-focused Pro to the premium Denali Ultimate. Animated lighting responds when owners approach or start the truck, bringing a contemporary element to the heavy-duty form. The overall shape reflects its utilitarian purpose while maintaining the refined character expected from the GMC brand—a truck equally suited to construction sites west of Winnipeg and downtown business meetings.

Substantial dimensions underscore the Sierra’s heavy-duty credentials. The Crew Cab Long Bed variant measures 6,776 mm in overall length atop a 4,369 mm wheelbase. Body width spans 2,079 mm on single rear wheel models, growing to 2,457 mm when dual rear wheels are specified for enhanced stability under maximum loads. Ground clearance ranges by configuration, topping out around 261 mm on select Crew Cab trims. Wheel offerings include 17-inch steel, 18-inch steel or aluminum, and available 20-inch and 22-inch aluminum designs. Glacier White Tricoat and Coastal Dune represent the fresh colour options for buyers seeking alternatives to the established palette.

Interior

The cabin balances rugged functionality with genuine comfort for operators logging substantial hours in the driver’s seat. Ergonomic placement of switches and controls supports intuitive operation even when wearing work gloves. Storage provisions throughout the interior accommodate the tools, documents, and devices that working professionals carry daily. In Crew Cab configuration, front row legroom measures 1,131 mm while rear passengers enjoy 1,102 mm—ample space for transporting crews between sites across the greater Winnipeg area.

Material and feature content escalates meaningfully through the trim range. Denali Ultimate represents the pinnacle, featuring full-grain leather with Alpine Umber colouring, open-pore Paldao wood with a darkened finish, and a premium microsuede headliner extending to visors and pillar surfaces. The 16-way power front seats incorporate massage functions for long-haul comfort. A 12-speaker Bose audio system provides rich sound quality. Heated and ventilated seating options available across upper trims prove their worth during Manitoba’s temperature extremes—from humid summer days to bitter January mornings.

Engine and Powertrain

Standard propulsion comes from a 6.6L V-8 gasoline engine delivering 401 horsepower at 5,200 rpm and 464 lb-ft of torque at 4,000 rpm. FlexFuel compatibility allows E85 use where available. This engine mates to the Allison 10-speed automatic transmission, which succeeded the previous six-speed unit. The additional gear ratios permit closer spacing between shifts, keeping the engine operating nearer its power peak during demanding situations. Drivers notice the difference as more readily available thrust for merging onto the Trans-Canada or climbing grades with loaded beds.

The available 6.6L Duramax Turbo-Diesel V-8 targets buyers who prioritize maximum pulling capability. This powerplant generates 470 horsepower at 2,800 rpm alongside 975 lb-ft of torque at a low 1,600 rpm. That abundant low-speed torque simplifies tasks like launching from intersections with heavy gooseneck trailers attached. The diesel likewise connects to the Allison 10-speed automatic. Both engine choices offer available 4WD systems, providing the grip needed to navigate Manitoba’s snow-covered winter roads and muddy spring conditions with confidence.

SLT now includes available MultiPro Tailgate for 2026, providing six functional configurations for varied loading scenarios. AT4 adds off-road suspension tuning and dedicated styling elements.
