"The new and enhanced 2024 Sierra HD builds on an already winning foundation," said Duncan Aldred, vice president of Global Buick and GMC. "This truck elevates the HD segment with the introductions of the Denali Ultimate trim and will soon add the seriously off-road capable AT4X trim, further strengthening the dominance of the GMC truck portfolio."

There are also new color and stitching designs throughout, with more premium materials throughout the cabin, further elevating the Sierra's premium look and feel.

First-ever Sierra HD Denali Ultimate – The Most Advanced and Luxurious Pickup in its Class

The first-ever Sierra HD Denali Ultimate is the most premium, luxurious and technologically advanced Sierra HD yet, equipped with unique enhancements to the overall design and premium interior appointments, more standard technologies and standard turbocharged performance with the enhanced 6.6L Duramax Turbo-Diesel and Allison 10-speed transmission.

Additionally, Denali Ultimate will include a six-way MultiPro Tailgate with a standard Kicker audio system. Power assist steps also come standard.

Inside, Denali Ultimate's exclusive Alpine Umber interior reaches new heights of premium luxury and comfort in a heavy-duty truck. Full-grain leather appointments and open-pore Paldao wood meticulously adorn the interior trim. The wood's darkened finish creates a distinctive color blend, while the unique graining adds bespoke attention to detail. Additional content includes:

More power, greater refinement for the Duramax Turbo-Diesel

The available enhanced 6.6L Duramax Turbo-Diesel, paired with the 10-speed Allison transmission, now delivers 470 hp (at 2800 rpm) and 975 lb-ft (at 1600 rpm) of torque, offering more power across the entire operating speed range. Specifically, low-end torque production increases up to 25% compared to the current model for improved towing performance.

The 2024 GMC Sierra HD will also offer best-in-class 2500 Crew Cab towing of up to 21,900 pounds and max 2500 towing of up to 22,500 pounds, enabled by a new available Max Tow Package.

Additional changes and upgrades were designed to produce a more efficient combustion and enhance overall performance. This latest iteration of the Duramax engines adds additional refinements including:

  • An all-new, more efficient turbocharger with improved efficiency to boost low-end torque
  • Increased power and torque over the entire operating speed range
  • Improved engine braking with a more powerful turbo vane actuator and uprated valve springs
  • New cylinder heads with improved cooling jackets
  • An all-new combustion system within the heads that's matched with next-generation, higher-flow injectors and greater fuel injection pressure
  • All-new engine controller

10-speed Allison transmission enhances gas-engine trailering capability

The Allision 10-speed automatic transmission is now paired with the Sierra HD's standard 6.6L gas engine. It replaces the previous six-speed automatic, offering smaller "steps" between the gears, which enables the 6.6L gas engine to hold closer to its peak power (401 horsepower and 464 lb-ft of torque) for longer periods.

That translates into a more confident feeling of on-demand power, regardless of whether the truck is towing a trailer – but when it is, trailering performance and capability are enhanced thanks in part to the 10-speed configuration, along with the capability of channeling every single pound-foot of torque to the tires in every gear.

Elevated and Purposeful Technology

The 2024 GMC Sierra HD will also offer the most trailering assistance technologies in the heavy-duty class through the available ProGrade Trailering System. The ProGrade Trailering System includes a suite of available intelligent trailering assistance technologies designed to help streamline the hitching and towing process, with integrated tools that help enhance customers' feelings of safety, confidence and visibility including these new enhancements:

  • Available Enhanced, Industry First Transparent Trailer View for Gooseneck and Fifth Wheel Trailering: Allows the driver to virtually "see through" the trailer. Using the camera mounted on the rear of the truck and an accessory camera on the back of the trailer, it pieces together a view of the area behind the truck and trailer as if the trailer was not there, improving visibility. An enhanced version of this technology for model year 2024 enables compatibility with gooseneck and fifth-wheel trailers.
  • Available Trailer Side Blind Zone Alert: Extends side blind zone alerts to include the blind zone areas around the trailer.
  • New GCW Alert: This all-new feature warns the driver if the vehicle and trailer weight exceed the vehicle's Gross Combined Weight Rating.
  • New, Available Adaptive Cruise Control with Trailering: Allows the Sierra HD's available Adaptive Cruise Control to be used while trailering and to account for additional drag and increased braking distances when towing a trailer.

In total, the 2024 Sierra Heavy Duty offers up to 14 available camera views including:

  • Hitch Guidance with Hitch View: Provides a close-up view of the receiver hitch to help with alignment when connecting to a trailer.
  • Bed View with Zoom and Bed Hitch Guidance: Allows you to see the cargo bed to help with fifth-wheel or gooseneck hitching or to briefly check on cargo.
  • Rear Side View with Trailer Length Indicator: With a compatible trailer attached and a turn signal activated, this view will show a full screen down the side of the truck along with a Trailer Length Indicator to aid in lane-change maneuvers by visually showing obstructions with the trailer in adjacent lanes.

High-Tech Digital Displays

The centerpiece of Sierra's high-tech interior cabin is the new available 13.4-inch-diagonal tablet-style touchscreen – the largest infotainment touchscreen in its class. Situated in landscape orientation, the touchscreen offers a user-friendly, customizable experience. An available multicolor 15-inch-diagonal head-up display and a new available 12.3-inch-diagonal digital instrument cluster are also added in 2024 model year. Together, this creates over 40 inches of immersive digital displays helping to provide an engaging, customizable and comprehensive driving experience.

The all-new touchscreen infotainment center can be configured to a user's preference, including the ability to operate multiple apps simultaneously in a "split-screen" view (e.g., a Navigation app running on the left side of the screen and a Music app on the right). Sierra HD's infotainment system will also integrate Google built-in (on all trims except Pro) allowing customers to connect virtually every aspect of their daily lives within their vehicle. The system is compatible with both Wireless Apple CarPlay and Wireless Android Auto.

Premium Safety Features

The 2024 model year will offer the standard, Sierra HD Pro Safety suite of driver assistance technologies, including:

  • Forward Collision Alert
  • Lane Departure Warning
  • Automatic Emergency Braking
  • Front Pedestrian Braking (new for 2024)

Also available on the 2024 Sierra HD is the Pro Safety Plus Package which includes new driver assistance features Rear Cross Traffic Braking and the Trailer Side Blind Zone Alert.
