The 2024 GMC Sierra 2500HD Denali comes exclusively in a Crew Cab cabin size and is available with both the standard bed or long bed configuration. The 6.6L V8 Gasoline engine mated to the 10-Speed Allison transmission is the standard powertrain pairing, with the 6.6L L5P Duramax Diesel engine is available as an upgrade. This powertrain pairing is an improvement over last year’s 2023 GMC Sierra 2500HD Denali, thanks to the new match to GM’s 10-Speed Automatic Allison Transmission.

Greater Connectivity and More Screen Surface Area

A new race to the top is taking place amongst automobile manufacturers, who can give consumers the most screen surface. Prior to 2023, GM’s trucks have struggled in this department, offering the smallest display compared to other manufacturers like Ford or Ram. Now, GMC and Chevy owners receive the much needed interior update and modernization consumers have been calling for.

The 2024 GMC Sierra 2500HD and 3500HD contain the 13.4″ Diagonal Touchscreen display as a standard feature. This display features Google Built-in, split-screen capabilities, and also contains bluetooth phone projection through Apple CarPlay or Android Auto. A 12.3″ Diagonal Digital Gauge Cluster and Driver Information Center is paired with the 13.4″ Touchscreen and it replaces the traditional analog gauges found on previous models. GM’s 12.3″ Driver Information Center is high customizable, allowing drivers to personalize their digital gauge cluster and control vehicle information like warning messages.

A 15″ Head-Up Display isn’t standard on the Denali trim, but it’s available as an upgrade. This feature projects vehicle information onto the windshield. This allows you to keep your attention on the road while still giving you vital vehicle information in your line of sight. If you’re interested in having the Head-Up display, you need to select either the Denali Reserve Package or the Technology package.

Two Different Color Interiors With More Premium Features

The 2024 GMC Denali HD interior comes available in two different color options, Jet Black and Atmosphere/Brownstone. Jet Black is an option that is available on the SLE and SLT models. The Atmosphere/Brownstone interior option, however, is unique to the Denali HD.

All Denali HD models, regardless of interior choice, come standard with bucket seats and a center console. This is contrary to the center seat that comes standard with SLE or SLT Trims. All throughout the interior Denali models also feature more decorative trim and premium features than lower trims.

Some examples of the standard premium interior characteristics of the 2024 GMC Sierra HD Denali 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.

While the 2024 GMC Sierra 2500HD Denali isn’t the top trim available in GMC trucks, it still offers buyers a modern pickup with a wide array of premium features.

It more closely resembles rivals lower trim levels, more comparative to Ford’s Lariat trim or Ram’s Laramie trim.

Compared to last year’s model, the 2024 Denali HD contains a number of much-needed upgrades that were implemented across all GMC HD truck trims. These upgrades make GM pickup trucks more competitive. GMC trucks gained a larger center infotainment center and a more intuitive digital gauge display that is highly customizable.
