More Tech

The 2024 GMC Sierra 3500HD Denali benefits from a number of technological improvements that make driving safer and easier.

2024 GMC Sierra 2500HD Denali Standard Features & Characteristics

The GMC Sierra 3500HD Denali is the second highest trim level in 2024 GMC trucks. It comes exclusively in a Crew Cab cabin configuration, with a short bed or long bed. It’s available in both SRW and DRW configurations and solely in 4WD. The 3500HD Denali also comes standard with the 6.6L V8 Gasoline Engine, but the L5P Duramax V8 Diesel engine is available as an upgrade.

Either powertrain now comes standard with the 10-Speed Allison transmission. This is a huge improvement compared to the 2023 GMC Sierra 3500HD Denali when selected with the 6.6L V8 gas engine, because it came with a basic 6-speed automatic transmission. This upgrade not only improves overall driving feel, but the Allison is also known for its reliability, so it should be a solid durability improvement as well.

Both the GMC’s Denali 3500HD’s Interior and Exterior was updated for the 2024 model year. The interior features numerous improvements such as significantly more screen surface area and the additions of more premium features. The Exterior still retains many of the foundational aspects of the Denali such as color-matched bumpers, classic chrome trim, and the signature Denali Grill. The exterior did benefit from some external revisions that were made to all GMC HD trucks in 2024 though, including new LED Headlights featuring Intellibeam.

Screen/Display Improvements

Every auto manufacturer is incorporating massive, intuitive center screens into their vehicles. At this point, it’s basically a competition. For the last few years, GM heavy duty trucks have really struggled in this department, offering the smallest and least impressive screen amongst heavy duty truck manufacturers. Both Ford and Ram have had 12″ Displays in their trucks for at least a couple of years now. In 2024, GM finally embraced the big screen and incorporated one of their own into their own HD trucks.

This screen, a 13.4″ diagonal touchscreen, is now the largest center infotainment screen in the vehicle class. It contains modern features like Google Built-in, split-screen capabilities, and bluetooth phone projection via Apple CarPlay or Android Auto. This display is paired with an updated 12.3″ Diagonal Digital Gauge Cluster or Driver Information Center, replacing the old analog gauges found on previous models. The new driver information center is highly intuitive and customizable, giving drivers more control and greater insight on their vehicle.

As if these displays aren’t enough, an optional 15″ Head-Up Display can be purchased as an upgrade. This feature projects vehicle information onto the windshield, eliminating the need to look down when driving. This feature is received by selected either the Denali Reserve Package or the Technology package.

Two Different Color Interiors With More Premium Features

The Denali HD interior is available with two distinct color options, Jet Black and Atmosphere/Brownstone. While the Jet Black interior color is available in lower trims, the Atmosphere/Brownstone interior is exclusive to the Denali.

The 2024 GMC Sierra 3500HD Denali comes standard with front buckets and a large center console, compared to lower trims containing a standard center seat. Throughout the cabin a greater concentration of premium materials and luxurious decorative trim are used compared to lower models.

Other premium features gained by selecting the Denali trim are:

  • A 7-Speaker Bose Sound System with a RichBass Woofer
  • Heated and Ventilated Front Seats
  • Heated Rear Seats
  • 12-Way Front Bucket seats for both the driver and front passenger, offering greater adjustability than lower trims.
  • Power-sliding rear window

Overall Thoughts on the 2024 GMC Sierra 3500HD Denali

While the Denali isn’t the most luxurious GM trim available any longer, the 2024 GMC Sierra 3500HD Denali is still a pickup worth considering if you’re in the market for a new truck. It’s significantly improved over previous models and finally contains more modern features that customers really care about. It’s a big step above SLE or SLT trim levels, and it offers many of the features found on the Denali Ultimate, with more being available as upgrades.

Most of the features that we are excited about have been changes that impacted all GMC HD trucks, not just the Denali. The additions of enlarged and more intuitive displays for the center infotainment center and the digital gauge cluster give an improved driving experience and allow drivers to customize settings and personalize their vehicle. A revised exterior gives the 2024 Denali HD a more aggressive look compared to 2023 models. The interior received a much-needed overhaul which make the trucks resemble more of a luxury vehicle than just a pickup truck.

The 2024 GMC Sierra 3500HD Denali is a great option for consumers wanting a premium pickup truck with numerous bells and whistles that make driving easier, safer, and more enjoyable. For those spending lots of time in their vehicles towing a camper or traveling for work, it should definitely be on your radar. That being said, the Denali lacks that “Wow Factor” when compared to the pinnacle trim model, the Denali Ultimate. While it may not make your jaw drop like the Denali Ultimate, the Denali trim level may prove itself to be more durable on the interior. Frequently trucks with the brown leathers like the King Ranch or the Laramie Longhorn can fade, resulting in a less desirable appearance.

Choose the Duramax

If you plan on towing, you should opt-in for the 6.6L L5P Duramax Diesel engine. The standard 6.6L V8 gasoline engine is okay for commutes or light duty towing, but the diesel will give you significantly better towing power, greater longevity, and even fuel economy when pulling a trailer. Once outfitted with the 6.6L L5P Duramax engine, the Denali model jumps from an MSRP of roughly $76,295.00 starting price, to $85,785 on SRW models. On DRW models, the base price is $78,695 with an upgraded model containing the L5P Duramax engine starts at $88,185.
