Technology

The available 13.4-inch diagonal touchscreen serves as the information and entertainment command centre, positioned in landscape format for convenient viewing. Split-screen operation permits simultaneous use of navigation and audio applications. Google built-in comes standard on trims above Pro, integrating voice control, real-time navigation, and connected services when activated with a data plan. Wireless Apple CarPlay and Android Auto enable smartphone pairing without cables. Additional available displays include a 15-inch diagonal multicolour head-up display and 12.3-inch configurable digital instrument cluster, combining with the centre screen for over 40 inches of viewable information.

The ProGrade Trailering System equips owners with up to 14 camera views designed to simplify hitching and towing operations. Enhanced Transparent Trailer View supports gooseneck and fifth-wheel setups, fusing rear truck and trailer camera images to present the zone behind as if seeing through the trailer itself. Trailer Side Blind Zone Alert monitors spaces beside the trailer during lane changes. Available Adaptive Cruise Control with Trailering factors in trailer drag and extended braking distances. The standard Pro Safety package includes Forward Collision Alert, Automatic Emergency Braking, Lane Departure Warning, and Front Pedestrian Braking.

Exterior

The Sierra 2500HD projects confident styling through trim-exclusive front-end designs. Grille patterns, bumper treatments, and fascia details distinguish each grade from entry-level Pro through flagship Denali Ultimate. Animated lighting sequences activate upon approach or ignition, lending technological sophistication to the truck’s muscular form. The body lines suggest both strength and purpose, with functional hood venting and prominent fender arches housing the substantial rubber required for heavy work. This design language serves Windsor owners navigating tight urban job sites and open highway stretches toward Detroit and beyond.

Physical dimensions reflect serious commercial intent. Crew Cab Long Bed models stretch 6,776 mm in total length on a 4,369 mm wheelbase. Width measures 2,079 mm with single rear wheels or 2,457 mm on dual rear wheel configurations engineered for maximum load stability. Ground clearance varies across the lineup, reaching approximately 261 mm on certain Crew Cab variants. Wheel selections range from functional 17-inch steel through premium 20-inch and 22-inch aluminum options depending on trim. The 2026 additions of Glacier White Tricoat and Coastal Dune broaden the colour spectrum for buyers wanting fresh exterior choices.

Interior

Inside, the Sierra 2500HD creates an environment where productivity and comfort coexist. The control layout keeps frequently used functions accessible without requiring drivers to divert attention from the road. Thoughtful storage solutions distributed throughout the cabin organize the phones, paperwork, and hand tools that working professionals carry daily. Crew Cab dimensions provide 1,131 mm of front legroom and 1,102 mm for rear occupants—adequate room for full crews heading to sites across Essex County or beyond.

Trim progression brings corresponding upgrades in materials and amenities. The range-topping Denali Ultimate features full-grain leather finished in Alpine Umber, complemented by open-pore Paldao wood accents with distinctive darkened tones. Front seats adjust 16 ways via power controls and include massage functionality for fatigue relief. Premium microsuede covers the headliner, visors, and pillar trim. A 12-speaker Bose sound system delivers audio clarity throughout the cabin. Heated and ventilated seat options across upper trims address the climate realities of southwestern Ontario, from sticky summer humidity to cold winter commutes.

Engine and Powertrain

The standard engine is a 6.6L V-8 producing 401 horsepower at 5,200 rpm with 464 lb-ft of torque at 4,000 rpm. This gasoline powerplant accepts E85 FlexFuel and pairs with the Allison 10-speed automatic transmission. The 10-speed gearbox replaced the earlier six-speed, offering refined shift quality and tighter ratio spacing that keeps engine speed closer to peak output during acceleration and load carrying. The tangible benefit appears as more immediate throttle response whether hauling materials from Windsor building suppliers or running unloaded to the next appointment.

For operators whose work demands maximum pulling muscle, the available 6.6L Duramax Turbo-Diesel V-8 produces 470 horsepower at 2,800 rpm and 975 lb-ft of torque at just 1,600 rpm. That low-rpm torque abundance simplifies heavy trailer launches and maintains momentum on highway grades. The diesel also routes power through the Allison 10-speed automatic. Available 4WD systems with electronic transfer case controls deliver traction assurance for Ontario’s variable weather conditions, from autumn rain to winter snow and ice.
