GM pulled the sheets on the fully refreshed 2024 GMC Sierra HD just a few days ago, revealing a long list of updates, changes, and upgrades. Among these was the debut of the new 2024 GMC Sierra HD Denali Ultimate, a fresh range-topping trim level offering a wealth of luxury and technology, as detailed right here.

Notably, the 2024 GMC Sierra HD Denali Ultimate marks the first time that the Sierra HD nameplate has offered the new Denali Ultimate trim level. The first model to receive the Denali Ultimate treatment was the fully refreshed 2022 GMC Sierra 1500, followed by the 2023 GMC Yukon.

Similar to the Sierra 1500 and Yukon, the 2024 GMC Sierra HD Denali Ultimate is equipped with unique styling touches that help it stand out from the rest of the lineup, starting with a unique grille finished in Vader chrome. Various exterior badging is also done in Vader chrome, while the fender badging shows off Mount Denali topography graphics, a running theme for each of the Denali Ultimate trims that have debuted thus far.

In the corners, the 2024 GMC Sierra HD Denali Ultimate rides on exclusive 20-inch Ultra-bright machined aluminum wheels with High Gloss black accents. Standard spec also includes a six-way MultiPro tailgate with a Kicker audio system and power assist steps .

Inside, the 2024 GMC Sierra HD Denali Ultimate is dripping with top-shelf finery, including exclusive Alpine Umber interior upholstery with full-grain leather and open-pore Paldao wood. Stainless-steel speaker grilles add a nice touch to the premium 12-speaker audio system, and front-seated passengers will enjoy the new 16-way power-adjustable and massaging front seats.

Onboard tech includes a standard rear camera mirror with full camera display and 15-inch diagonal head-up display. Up top is a standard power sunroof.

As for the greasy bits, the 2024 GMC Sierra HD Denali Ultimate cradles the 6.6L V8 L5P turbodiesel Duramax engine as standard. The latest 2024-model-year refresh brings peak output from the diesel engine to 470 horsepower and 975 pound-feet of torque, as compared to the 445 horsepower and 910 pound-feet of torque on tap previously. The V8 connects to the Allison-branded 10-speed automatic transmission. Notably, the rest of the lineup equips the naturally aspirated 6.6L V8 L8T gasoline engine as standard, which also pairs to the Allison-branded 10-speed automatic transmission.

Under the body panels, the refreshed 2024 GMC Sierra HD once again rides on the more-capable variant of the GM T1 platform. Production is set to take place at the GM Flint plant in Michigan.
