• New 22-inch accessory wheels
• Six new exterior colors (extra cost): Titanium Rush Metallic, Sterling Metallic, Volcanic Red Tintcoat, Redwood Metallic, Meteorite Metallic and Downpour Metallic
• Rear wheelhouse liners standard on Denali and Denali Ultimate dual rear-wheel models

Internally, GMC's team of designers has distinguished the Sierra model from its competitors through the introduction of distinct and novel interior designs for the SLE and SLT trims. Moreover, unique GMC premium interior designs have been meticulously crafted for the AT4, Denali, and Denali Ultimate trims. The interior enhancements extend to new color palettes and stitching patterns, seamlessly integrated throughout the cabin. These modifications, coupled with the integration of elevated materials, serve to enhance the Sierra's overall premium aesthetics and tactile experience.

The inaugural Sierra HD Denali Ultimate model represents the epitome of premium, opulent, and technologically advanced Sierra HD iterations. This iteration is enriched by distinctive augmentations to its overall design and lavish interior appointments, in addition to an expanded array of standard technologies and an upgraded turbocharged performance, facilitated by the advanced 6.6L Duramax Turbo-Diesel engine and Allison 10-speed transmission.

The Denali Ultimate variant is readily discernible by its exterior, which boasts an exclusive grille and GMC badging in the elegant Vader chrome finish. The presence of unique 20-inch Ultra-bright machined aluminum wheels, accentuated with High Gloss black accents, further contributes to its distinguished appearance. Notably, the fender badging showcases the topography of Mount Denali, North America's highest peak. Furthermore, the Denali Ultimate model boasts a six-way MultiPro Tailgate as a standard feature, complemented by a Kicker audio system and power assist steps.

Stepping into the interior, the Denali Ultimate exudes an unmatched sense of luxury and comfort, surpassing previous benchmarks for heavy-duty trucks. The cabin is adorned with full-grain leather appointments and open-pore Paldao wood trim, meticulously curated to create an atmosphere of refined elegance. The darkened finish of the wood trim imparts a distinctive color interplay, while the unique grain pattern reflects a meticulous attention to bespoke craftsmanship. Additional enhancements encompass:

• Full-grain leather-wrapped door panels with etched stainless-steel speaker grilles
• Full-grain leather front and rear seats with the Denali Ultimate badge on the front seatbacks and center console lid
• All-new 16-way power-adjustable and massaging front seats
• Premium microsuede headliner, visors and A- and B-pillar trim along with leather-wrapped A- and B-pillar handles
• 12-speaker Bose® Premium series with Centerpoint surround technology
• Standard rear camera mirror, with full camera display
• Standard 15-inch-diagonal multicolor head-up display
• Standard power sunroof

The available upgraded 6.6L Duramax Turbo-Diesel, in conjunction with the 10-speed Allison transmission, now provides an impressive output of 470 horsepower (at 2800 rpm) and a substantial 975 lb-ft of torque (at 1600 rpm), signifying a notable augmentation in power throughout the entire operational spectrum. Particularly noteworthy is the 25% surge in low-end torque production in comparison to the current model, resulting in markedly improved towing capabilities.

Furthermore, the 2024 Sierra HD will establish new benchmarks with its towing prowess, offering an unrivaled 2500 Crew Cab towing capacity of up to 21,900 pounds and an exceptional maximum 2500 towing capacity of up to 22,500 pounds, achievable through the incorporation of the new optional Max Tow Package.

A series of additional enhancements and modifications have been meticulously devised to optimize combustion efficiency and elevate overall performance. This latest iteration of the Duramax engine introduces supplementary 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
• Enhanced Gas-Engine Trailering Capability Achieved Through 10-Speed Allison Transmission

The Sierra HD's standard 6.6L gas engine now benefits from the integration of the Allision 10-speed automatic transmission, supplanting the previous six-speed counterpart. This upgrade introduces finer gear transitions, facilitating a more seamless power delivery experience. The refined gear ratios allow the 6.6L gas engine to sustain proximity to its peak power output (401 horsepower and 464 lb-ft of torque) for extended durations.

Consequently, this refinement translates into a heightened sense of assured, readily available power, regardless of whether the vehicle is engaged in trailer towing activities. Moreover, during towing operations, the 10-speed configuration notably contributes to an elevated level of trailering performance and capability. This is further reinforced by the transmission's ability to efficiently channel the entirety of torque – measured in pound-feet – to the tires in each gear, thereby accentuating the Sierra HD's overall trailering prowess.

The new 2024 Sierra HD model stands out by providing an extensive array of trailering assistance technologies, solidifying its leadership in the heavy-duty class. This achievement is made possible through the incorporation of the advanced ProGrade Trailering System, an available feature designed to simplify and optimize the hitching and towing procedures. Comprising a suite of intelligent trailering assistance technologies, the ProGrade Trailering System is crafted to augment customer experiences by instilling heightened sensations of safety, confidence, and visibility. The system encompasses an assortment of integrated tools, including the following newly introduced 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.

The 2024 Sierra offers up to 14 available camera views.

• 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

At the heart of Sierra's technologically advanced interior cabin lies the newly available 13.4-inch-diagonal tablet-style touchscreen — unrivaled as the largest infotainment touchscreen within its class. Positioned horizontally, this touchscreen interface delivers a user-friendly and customizable interaction. The 2024 model year introduces additional enhancements, including the availability of a multicolor 15-inch-diagonal head-up display and a new 12.3-inch-diagonal digital instrument cluster. Collectively, these innovations combine to offer an expansive expanse of over 40 inches of immersive digital displays, contributing to a dynamic, adaptable, and all-encompassing driving experience.

The novel touchscreen infotainment hub can be effortlessly tailored to suit individual preferences, permitting the operation of multiple applications concurrently in a "split-screen" layout. This versatile arrangement, for instance, allows the simultaneous use of a Navigation app on the left side while accessing a Music app on the right. Enriching the infotainment ecosystem, the Sierra HD's system seamlessly integrates Google built-in (except Pro trim), enabling users to seamlessly interconnect various facets of their daily routines within the vehicle. Furthermore, compatibility extends to both Wireless Apple CarPlay and Wireless Android Auto, ensuring a seamless connectivity experience.
