2024 GMC Sierra 2500 HD Denali Ultimate: A Luxurious House on Wheels

If you're in the market for one of the most capable pickup trucks available today, the 2024 GMC Sierra 2500 HD Denali Ultimate is a vehicle you should seriously consider. In this review, we'll delve into the luxurious features and impressive capabilities that make this truck a standout choice for those who want both power and style. Thanks to GMC for providing this model for a test, we're excited to take you on a journey through its features and performance.

The King of Pickup Trucks

Pickup trucks have gotten absolutely absurd over the last decade. Once regarded as tools for the job, offered only with regular cabs, bench seating for 3, and a long bed, pickup trucks now have to be the work vehicle, family hauler, date night ride, and more. Buyers demand that their trucks not only be tough enough for the job but also look good enough for pulling up to the country club or make a statement on the boat ramp. At least, that is how it is here in Texas. For the 2024 model year, GMC launches the Denali Ultimate line to its Sierra pickups. Taking what was already one of the most luxurious options in the market with its Denali sub-brand, the Denali Ultimate makes an even more exclusive but luxurious offering for pickup truck buyers who desire more opulence.

Exterior: A Bold Presence

At first glance, the 2024 Sierra 2500 HD Denali Ultimate captures attention with its understated extravagance, its massive presence, and upgraded design. The front end is dominated by the imposing Vader chrome grille, which is less bling than the Denali’s traditional chromed look, but gives the truck a distinct understated appearance. Full LED headlights, C-channel running lights, and LED fog lights contribute to its bold aesthetic.

The truck's size is remarkable, standing next to it makes me look short as I can only see over the hood. I am grateful for not only the power-deployable running boards, but also the bedside step just behind the cab, and the corner steps on the rear bumper. Gaining access to the bed is also made simple thanks to the standard Multi-Pro tailgate which is essentially a small tailgate within the larger tailgate, which allows for 6 positions including a step with a deployable handle for easy entry into the bed.

Under the Hood: Power and Performance

Perhaps the biggest upgrade to the HD line of Sierra pickups for 2024 is the increased power in the optional 6.6-liter Duramax diesel engine. This powerhouse delivers 470 horsepower and a staggering 975 pound-feet of torque at just 1600 rpm, making it more than capable of handling heavy loads and towing with ease. That is 25% more low-end torque than on the 2023 model. It is clear this truck is built for hauling and towing, and its impressive performance numbers reflect that. As ours was equipped, we could tow up to 19,100 pounds via a fish wheel connection. Spec your Sierra 2500 HD crew cab differently and you can pull up to 21,900, a segment best.

Interior: Where Luxury Meets Functionality

Step inside the 2024 Sierra 2500 HD Denali Ultimate, and you're greeted by an interior that exudes luxury and comfort. From the exquisite stitching on the door panels to the embossed topographical map of Denali National Park that is literally everywhere, attention to detail is evident throughout. The combination of brown and black contrasting leather, along with wood accents, creates a premium atmosphere that rivals other truck makers and gives the aroma of a high-end furniture store or the boot section of our local western wear store. The seats are not just comfortable but also offer dual-location heat (seat and back or back only), ventilation, and even massage functions to relax you on your drive home after a long day of manual labor.

The cabin is equipped with advanced technology, including a 13-inch infotainment screen with wireless Apple CarPlay and Android Auto, a head-up display, and a host of driver assistance features. The 360-degree camera system is particularly impressive, providing a multitude of angles for various scenarios, including trailering.

Driving Experience: Powerful and Smooth

Despite its imposing size, the 2024 Sierra 2500 HD Denali Ultimate handles with surprising agility. Its turning radius allows for relatively tight maneuvers, making it more maneuverable than one might expect. We were able to pilot it around town without issue, though here in Texas the roads are made for these big beasts. On the road, it provides a comfortable ride, absorbing bumps and imperfections with its Rancho shocks.

Final Thoughts: A Luxury Powerhouse

The 2024 GMC Sierra 2500 HD Denali Ultimate is more than just a pickup truck; it's a status symbol, a workhorse, and a luxurious sanctuary on wheels. Whether you're towing a trailer, cruising around town, or simply enjoying the comfort of its interior, this truck delivers an experience that's second to none. GMC has truly raised the bar with the Denali Ultimate trim, offering a combination of power, style, and luxury that's hard to match.

If you're looking for a pickup truck that's not only capable but also delivers a premium driving experience, the 2024 GMC Sierra 2500 HD Denali Ultimate should be at the top of your list. It's a vehicle that exemplifies the best of both worlds and for those who demand the very best, it's an option that won't disappoint.
