What's new on the 2024 GMC Sierra HD?

Technology

The 2024 Sierra HD leads its class with innovative technology. Central to this is the new 13.4-inch-diagonal tablet-style infotainment touchscreen, offering a customizable and user-friendly interface. The integration of Google built-in (except on the Pro trim) and compatibility with Wireless Apple CarPlay and Android Auto ensures seamless connectivity. The truck also features a new 12.3-inch-diagonal digital instrument cluster and a 15-inch-diagonal head-up display, providing drivers with comprehensive and easily accessible vehicle information.

These technological advancements enhance the driving experience and user convenience. The split-screen capability of the infotainment system allows drivers to simultaneously access navigation and entertainment, improving usability. The head-up display and digital instrument cluster offer vital information without distracting from the road, increasing safety. Compared to previous models, these upgrades represent a significant leap in in-cabin technology, making the Sierra HD more connected and intuitive to operate. Furthermore, the inclusion of ProGrade trailering technology, offering up to 14 camera views, elevates towing safety and convenience to new levels.

Exterior

The 2024 Sierra HD showcases a refreshed exterior that exudes both sophistication and functionality. Each trim, including the Pro, SLE, SLT, AT4, Denali, and Denali Ultimate, features distinct grille designs and finishes, enhancing the truck's visual appeal. The exterior redesign includes a revised front bumper and fascia, contributing to a more commanding presence. Animated lighting that activates upon approach, start, or when using turn signals, adds a modern touch. New wheel designs are evident across various trims, including larger 18-inch polished aluminum wheels for dual-rear-wheel models and new 22-inch accessory wheels, augmenting the truck's robust stance.

The exterior modifications of the 2024 Sierra HD are not just aesthetic but also serve practical purposes. The revised front end design aids in aerodynamics and cooling efficiency, crucial for maintaining performance under heavy loads. The animated lighting enhances safety and visibility, particularly in low-light conditions. Wheel design updates, especially the larger options for dual-rear-wheel models, contribute to improved stability and handling, essential for towing and hauling. Additionally, the introduction of six new exterior colors, including premium options like Titanium Rush Metallic and Redwood Metallic, allows for greater personalization and appeal.

Interior

Inside the 2024 Sierra HD, GMC has elevated the cabin experience significantly. The new interiors, distinct across the SLE and SLT trims, as well as the premium AT4, Denali, and Denali Ultimate trims, showcase a commitment to luxury and customization. Attention to detail is evident in the new color and stitching designs and the use of more premium materials throughout the cabin. This upgrade in interior aesthetics enhances the Sierra's premium feel, catering to a wide range of customer preferences and ensuring a sophisticated environment for both work and leisure.

The interior of the 2024 Sierra HD is a blend of comfort and practicality. Full-grain leather appointments and open-pore Paldao wood in the Denali Ultimate trim, for instance, exemplify luxury in a heavy-duty truck. The cabin's layout is designed with ergonomics in mind, ensuring ease of access to controls and storage. New 16-way power-adjustable and massaging front seats in the Denali Ultimate add a layer of comfort, particularly for long drives. The premium microsuede headliner and leather-wrapped handles contribute to a refined and tactile experience, while the advanced 12-speaker Bose Premium audio system enhances the in-cabin entertainment experience.

Engine and Powertrain

The 2024 Sierra HD boasts an enhanced powertrain, central to which is the available 6.6L Duramax Turbo-Diesel V8 engine, paired with a 10-speed Allison transmission. This formidable combination delivers 470 horsepower and 975 lb-ft of torque. The engine's redesign includes a more efficient turbocharger and a new combustion system, resulting in improved performance across the operating range. The truck also features a robust 6.6L gas engine, now paired with a 10-speed Allison transmission, enhancing its trailering capability by optimizing power delivery.

These technical advancements translate into tangible performance benefits. The increased low-end torque, up by 25% compared to the current model, ensures a more immediate and responsive power delivery, essential for towing and hauling heavy loads. The 2024 Sierra HD has a base towing capacity of 18,500 pounds for the Sierra 2500 HD and a maximum towing capacity of 36,000 pounds for the Sierra 3500 HD with the Duramax Turbo-Diesel powertrain. The 10-speed transmission in both diesel and gas variants provides smoother gear shifts, maintaining the engine in its optimal power band. This not only improves driving dynamics but also contributes to fuel efficiency, particularly under load. The Sierra HD's enhanced engine braking and improved cooling systems further bolster its performance, ensuring reliability and longevity even under strenuous conditions.
