What’s New for 2026?
The latest model year focuses heavily on improving digital connectivity, towing support systems, and overall driver convenience. GMC refines available trim equipment while expanding the integration of premium technology across more configurations.
Updated infotainment responsiveness, enhanced camera functionality, and improved trailering assistance technologies help simplify heavy hauling situations. Compared to last model New wheel options and refined exterior detailing also give the truck a more commanding and upscale appearance.
The newest generation continues emphasizing luxury-level refinement inside the cabin while preserving the durability expected from a heavy-duty pickup.
Powerful Engine Options Built for Serious Capability
Performance remains the defining strength of this HD truck lineup. Drivers can choose between a robust gasoline V8 engine or the available turbo-diesel powertrain engineered for maximum towing capability and low-end pulling power.
The available 6.6-litre Duramax turbo-diesel V8 produces approximately 470 horsepower and a remarkable 975 lb-ft of torque, delivering exceptional confidence for hauling heavy trailers, equipment, and recreational vehicles across Ontario highways.
A 10-speed Allison automatic transmission improves power delivery, towing stability, and highway efficiency while maintaining smoother acceleration under heavy loads.
Key capability highlights include:
- Advanced trailer towing technologies
- Integrated trailer brake controller
- Multi-view towing camera system
- 3,6000 lbs of towing capability
- Available off-road suspension setups
- Large wheel options up to 20 inches
- Exceptional payload and towing capacity
The diesel configuration remains especially useful for drivers who regularly tow in challenging Canadian weather and on varying terrain.
Bold Exterior Styling With Functional Design
The latest styling combines muscular proportions with premium design cues that elevate the truck beyond a traditional work-focused appearance. A large grille design, signature LED lighting, sculpted hood lines, and aggressive stance create an unmistakably commanding road presence.
Functional exterior details remain equally important. Integrated bed steps, cargo tie-down systems, spray-in bed liners, and available MultiPro tailgate technology improve usability during both professional and recreational use.
The exterior design balances rugged durability with upscale styling, helping the truck feel equally at home on construction sites or on the streets of downtown Ottawa.
Premium Interior Comfort Meets Modern Technology
Inside, the cabin delivers one of the most refined environments in the heavy-duty segment. High-quality materials, spacious seating, and advanced digital integration create a premium atmosphere designed for long-distance comfort.
A large available 13.4-inch infotainment touchscreen becomes the center of the dashboard, offering crisp graphics and intuitive controls for navigation, entertainment, and towing management systems. Wireless Apple CarPlay and Android Auto provide seamless smartphone connectivity without cable clutter.
Drivers also benefit from a configurable digital instrument display that delivers real-time towing information, performance data, and safety alerts directly in the line of sight.
Available comfort and technology features include:
- Heated and ventilated front seating
- Wireless charging capability
- Premium Bose audio system
- Google Built-In connectivity
- Multiple USB charging ports
- Head-up display technology
The spacious cabin and flexible cargo storage solutions make the truck practical for both family travel and demanding work schedules.
Advanced Safety and Towing Assistance
Modern heavy-duty trucks require more than raw strength, and GMC integrates several advanced safety technologies designed to improve confidence behind the wheel.
Available systems include forward collision alert, automatic emergency braking, lane departure warning, blind-zone steering assist, adaptive cruise control, and rear cross-traffic braking.
One standout feature is the advanced transparent trailer view technology that helps drivers virtually “see through” larger trailers for safer maneuvering and lane changes.
For Ontario drivers facing snow, traffic congestion, and long highway distances, these systems provide valuable support during daily driving and towing situations.
