What’s new on the 2026 GMC Sierra 2500 HD?
Technology
The available 13.4-inch diagonal infotainment touchscreen occupies a prominent central position, oriented in landscape format. Users can divide the display between applications—running navigation alongside audio controls, for example. Google built-in integration arrives standard on trims above Pro, delivering voice-activated assistance, real-time mapping, and connected services with an active data subscription. Wireless Apple CarPlay and Android Auto maintain smartphone connectivity without cables. Optional displays include a 15-inch diagonal multicolour head-up display and 12.3-inch digital instrument cluster, combining for over 40 inches of digital information surfaces.
The ProGrade Trailering System addresses the challenges inherent in heavy towing through up to 14 available camera angles. Enhanced Transparent Trailer View supports gooseneck and fifth-wheel setups, merging camera feeds to reveal the area behind the trailer as if it were not there. Trailer Side Blind Zone Alert watches for vehicles alongside the trailer during passing maneuvers. Available Adaptive Cruise Control with Trailering adjusts speed while accounting for trailer drag and extended stopping distances. The standard Pro Safety suite bundles Forward Collision Alert, Lane Departure Warning, Automatic Emergency Braking, and Front Pedestrian Braking.
Exterior
Visual authority defines the Sierra 2500HD from every angle, beginning with trim-specific grille treatments that distinguish each model in the lineup. Animated lighting sequences illuminate when drivers approach or activate the ignition, casting a technical signature. The truck’s proportions telegraph serious intent—a high beltline and substantial fender flares frame the bodywork while functional air intakes support cooling demands under heavy loads. This purposeful stance serves Prince Albert area owners well when navigating resource roads or pulling into remote worksites.
Dimensional specifications confirm the truck’s heavy-duty classification. Crew Cab Long Bed models extend 6,776 mm bumper to bumper, riding on wheelbases up to 4,369 mm. Single rear wheel body width measures 2,079 mm, while dual rear wheel configurations span 2,457 mm for enhanced load stability. Ground clearance varies by trim and configuration, with Denali and Denali Ultimate Crew Cab models offering approximately 261 mm. Available wheel sizes progress from 17-inch steel through 20-inch and 22-inch aluminum options depending on trim selection. The 2026 colour additions—Glacier White Tricoat and Coastal Dune—expand exterior personalization choices.
Interior
Stepping inside reveals a workspace designed for professionals who demand function without forsaking comfort. The dashboard architecture positions primary controls within natural reach, reducing distraction during demanding driving situations. Generous storage throughout the cabin keeps documents, tools, and personal gear organized and accessible. Front occupants enjoy 1,131 mm of legroom in Crew Cab models, with rear passengers receiving 1,102 mm—sufficient space for work crews commuting to distant job sites north of Prince Albert.
Interior appointments progress substantially across trim levels. The flagship Denali Ultimate wraps surfaces in full-grain leather with Alpine Umber colouring, accented by open-pore Paldao wood with a distinctive darkened finish. Front seats adjust 16 ways with power controls and include massage functionality. A premium microsuede headliner covers the ceiling and extends to visors and pillar trim. The 12-speaker Bose audio system delivers quality sound reproduction. Available heated and ventilated seats across multiple trims address the practical reality of Saskatchewan’s dramatic seasonal temperature range, from summer heat to deep winter cold.
Engine and Powertrain
The base powertrain centers on a 6.6L V-8 gasoline engine rated at 401 horsepower (5,200 rpm) and 464 lb-ft of torque (4,000 rpm). This engine runs on regular gasoline or E85 FlexFuel where available. Power routes through the Allison 10-speed automatic transmission, which offers closer gear ratios than the previous six-speed unit. Those tighter steps keep engine speed nearer to peak power during acceleration and hill climbing, translating to more confident performance whether the truck runs loaded or empty.
Operators seeking maximum work capacity can opt for the 6.6L Duramax Turbo-Diesel V-8. Output reaches 470 horsepower at 2,800 rpm with 975 lb-ft of torque arriving at just 1,600 rpm. That substantial low-end torque proves valuable when pulling heavy trailers away from stops or maintaining momentum on grades. The diesel also pairs with the Allison 10-speed automatic. Available 4WD configurations with electronic transfer cases provide the traction security needed during Saskatchewan’s prolonged winter months and spring breakup conditions.
Versions
The 2026 Sierra 2500HD range builds from Pro through SLE, SLT, AT4, Denali, and Denali Ultimate, with the AT4X variant delivering focused off-road capability. Pro trim serves commercial and fleet buyers with fundamental heavy-duty functionality. SLE layers in additional convenience features and interior refinements. SLT gains MultiPro Tailgate availability for 2026, adding six distinct tailgate configurations for easier loading. AT4 targets off-road use with dedicated suspension tuning and visual treatments. Denali elevates the luxury quotient with premium materials and the distinctive Vader chrome grille. Denali Ultimate reaches the apex with exclusive 20-inch Ultra-bright machined aluminum wheels, full-grain Alpine Umber leather, power sunroof, and the six-way MultiPro Tailgate with integrated Kicker audio. Regular Cab, Double Cab, and Crew Cab body styles offer standard or long bed options by configuration.
