2024 GMC Sierra 2500 HD Denali & Denali Ultimate

GMC’s integrated trailer camera system and in-house trailering app reduce white-knuckle moments, while adaptive cruise control now factors trailer length to maintain safer gaps—a feature highlighted on the official site’s safety list (adaptive cruise control now factors trailer length).

Interior: A Lounge with a Payload Rating

Open the door and the “professional grade” slogan suddenly feels like an understatement. Perforated leather seating, open-pore wood, and a 12-speaker Bose audio system cocoon passengers in near-Yukon-Denali comfort. Dealer inventory for 2025 models even shows dual-zone automatic climate, heated and ventilated front & rear seats, plus a power sunroof as standard kit on Denali Ultimate (dual-zone automatic climate…power sunroof).

Tech dominates the dash: a 13.4-inch Google-built-in infotainment screen, 12.3-inch digital cluster, and a massive 15-inch head-up display project everything from tire-pressure readouts to turn-by-turn navigation. Toliver Buick GMC lists the same layout on its 2026 early-order units, citing the 13.4-inch GMC Premium Infotainment System with wireless Apple CarPlay/Android Auto (13.4-inch GMC Premium Infotainment System).

Safety & Driver Assistance

Standard safety tech rivals many luxury sedans:

• Lane-Departure Warning
• Front & Rear Park Assist
• Rear Cross-Traffic Alert
• HD Surround-Vision camera (providing up to 14 views)

Gee GMC further points to automatic emergency braking and OnStar crash detection that can summon help automatically (automatic emergency braking and OnStar crash detection). On the road, the sheer size of the truck remains undeniable, but the 360-degree cameras and blind-zone indicators take much of the anxiety out of tight city streets.

Pricing & Trim Walk

From GMC’s configurator, the Sierra 2500 HD Denali starts just under $77,000, while the Denali Ultimate pushes beyond $96,000 before options (starts just under $77,000…beyond $96,000). The gulf primarily buys:

• Power-retractable assist steps
• Full-grain leather & massaging front seats
• 22-inch wheels (vs. 20 in.)
• Standard 6.6L Duramax vs. optional on Denali

When cross-shopping, note incentives: new or current GM Rewards Cardmembers can earn up to 50,000 Bonus Points toward accessories or service with a new GMC purchase (earn up to 50,000 Bonus Points).

Ownership Costs & the Used Market

Running costs will hinge on fuel choice; the Duramax averaged an observed 17 mpg highway in our week—respectable for a truck this heavy. For buyers hunting pre-owned, CARFAX stresses the importance of checking for prior accidents, import history, and manufacturer recalls via its extensive vehicle-history database (importance of checking for prior accidents…recalls). Given many HD trucks lead hard lives—commercial plowing, fifth-wheel towing—those reports are money well spent.

Everyday Usability

1. MultiPro Tailgate: Deploy the inner gate as a laptop stand, then fold out the step to load mulch bags without a ladder—brilliant.
2. Bed View Camera: Aligning a 14,000-lb boat is child's play; the in-dash zoom makes hitting the gooseneck ball first try achievable.
3. Cabin Storage: A double-stacked glovebox, under-seat bins, and a cavernous center console swallow laptops, tool bags, and the inevitable fast-food stash.

Downsides Worth Mentioning

• Size: At 250.0 inches long, standard parking garages are a squeeze.
• Price Creep: Tick a few accessories—spray-in liner, power sunroof, rear-seat media—and the sticker eclipses $100K.
• Diesel Premium: The Duramax adds roughly $9,500 over the 6.6-liter gas V8 and demands DEF fluid plus pricier fuel.

Verdict: Luxury Without Compromise

For contractors who sign checks in the field or families who haul horses on Saturday and the Airstream on Sunday, the Sierra 2500 HD Denali family is arguably the ultimate do-all truck. It tows like a dually, pampers like a Denali Yukon, and flaunts technology that takes the intimidation factor out of piloting a 7,500-lb rig. If your budget allows—and your driveway fits—this is the heavy-duty pickup that lets you arrive covered in mud yet step out onto power-deploying chrome steps in a pressed shirt.

In short, the 2024 GMC Sierra 2500 HD Denali and Denali Ultimate prove you really can have your steak and caviar in the same lunchbox.
