2024 GMC Sierra HD

MORE TECH, MORE PULLING POWER

The 2024 Sierra HD takes the GMC HD lineup to new heights with updated interior, elevated technologies and more pulling power — offering the most trailering assistance technology in its class. The new and enhanced 2024 Sierra HD builds on an already winning foundation. 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.

The 2024 Sierra HD lineup includes 2500HD and 3500HD models, in Regular Cab, Extended Cab and Crew Cab configurations — with dual-rear-wheel models available on 3500HD. Available trims include Pro, SLE, SLT, AT4, Denali and Denali Ultimate, with the AT4X trim coming later in the model year.

Heavy Duty Highlights:

  • Updated technologies including an available new, largest in-class1 13.4-inch-diagonal tablet-style infotainment touchscreen
  • Most available trailering assistance technologies in its class through GMC’s ProGrade trailering system, offering up to 14 camera views
  • Enhanced power with the combination of the available 6.6L Duramax Turbo-Diesel V-8 and 10-speed Allison transmission delivering 470 horsepower and 975 lb-ft of torque and providing 25% more low-end torque vs the current model for a greater feeling of power on demand
  • Max towing across the lineup, including:
    • Up to 21,9002 pounds on 2500HD Crew Cab – best in class
    • Up to 22,5003 pounds on 2500HD – a 4,000-pound increase over the current model
    • Up to 36,0004 pounds on 3500HD

2024 GMC Sierra HD

ULTRA-PREMIUM INTERIOR

Inside, GMC designers set the 2024 Sierra HD apart from the competition with unique, new interiors on SLE, and SLT trims, as well as unique GMC premium interior designs for AT4, Denali and Denali Ultimate trims. 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.

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. 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.

First-ever Sierra HD Denali Ultimate

The all-new 2024 GMC Sierra Denali Ultimate is the most advanced and luxurious pickup in its class. The top-of-the-line 2024 GMC Sierra Denali Ultimate offers exclusive exterior and interior elements, more standard technologies, and standard turbocharged performance with the enhanced 6.6L Duramax Turbo-Diesel and Allison 10-speed transmission.

The 2024 Sierra Denali Ultimate is distinguished by an exterior featuring a unique grille and GMC badging in exclusive Vader chrome, along with exclusive 20-inch Ultra-bright machined aluminum wheels with High Gloss black accents, and unique fender badging featuring topography of Mount Denali. Additionally, Denali Ultimate will include a six-way MultiPro Tailgate with a standard Kicker audio system.

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.

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 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.
