Highlight #3: Standard L5P Duramax Diesel Engine

Without a doubt, the best standard feature Denali Ultimate HD trucks come with is the 6.6L L5P Duramax Diesel engine. On all other trims, this is an expensive upgrade. It gives drivers of the 2024 GMC Sierra 3500HD Denali Ultimate the most capable powertrain they have to offer and significantly improves towing capabilities and overall longevity.

2024 GMC Sierra 3500HD Denali Ultimate Performance

The 2024 GMC Sierra 3500HD Denali Ultimate boasts significantly more impressive standard performance than all other trim levels. That is because the highly-coveted 6.6L L5P Duramax Diesel V8 Engine comes standard with this trim. At 470 horsepower and 975 lb-ft of torque, it easily outshines the 6.6L V8 Gasoline engine found as the standard engine offering on all other trims. It also does a significantly better job towing, and offers buyers that incredible longevity and durability we’ve become accustomed to with diesel trucks.

The L5P Duramax engine is mated to the newest version of the 10-speed Allison Transmission. This powertrain combination provides one of the smoothest and most comfortable rides possible. It simultaneously gives the truck smaller steps between gears, allowing the truck to experience a longer interval of peak power.

In addition to containing an upgraded powertrain combination, all Denali Ultimate heavy duty trucks come in 4WD and a crew cab configuration.

The 2024 GMC Sierra 3500HD Denali Ultimate is the ultimate towing machine right when it rolls off the lot. Thanks in large part to the 6.6L L5P Duramax mated to the Allison Transmission, these trucks can handle almost anything you can throw at them.

2024 GMC Sierra 3500HD Denali Ultimate Interior

While all 2024 GMC Sierra 3500HD trucks benefit from a much-needed interior overhaul for this model year, the Denali Ultimate takes it several steps beyond that. Incredible attention to detail and significant amounts of time were put into developing a cabin that is worthy of the name Denali Ultimate. Here is everything you need to know about the 2024 GMC Sierra 3500HD Denali Ultimate Interior.

2024 GMC SIERRA 2500HD DENALI ULTIMATE INTERIOR

More Luxurious Cabin Designed with Premium Materials

The 2024 GMC Sierra 3500HD Denali Ultimate interior is the most impressive interior of any GMC truck to date. It stands head and shoulders above the interior of the 2024 GMC Sierra 3500HD Denali, the next highest trim in GMC’s lineup.

The Denali Ultimate contains a unique Alpine Umber interior. Full-grain leather, often considered the highest quality leather, is used throughout the cabin in the seats, door panels, and console. Open-pore Paldao wood is used throughout the cabin on interior trim, and much of the trim is engraved with topographical map patterns of Mt. Denali’s Summit. The Denali Ultimate badge is placed on the front and rear seats in addition to the center console. The headliner, visors, and pillar trim are adorned with premium microsuede and leather is even found on pillar trim handles.

Both front passengers benefit benefit from 16-way power-adjustable and massaging seats. Driver’s gain the most intuitive center display and instrument display or gauge cluster ever offered on a GM pickup truck. A 12-speaker Bose Premium Series Sound system features Counterpoint surround technology, and etched stainless-steel speakers are used in the door panels.

A New Center Display Winner

GM trucks have contained the smallest and least intuitive center display and gauge display amongst heavy duty truck manufacturers. When you compared them to the RAM HD’s 12″ vertical display, or Ford’s 12″ horizontal display, the size and the lack of features was a serious shortcoming. While it doesn’t necessarily matter in a work truck, customers shopping for a luxury pickup truck care about these features. That all changes for this model year however, GMC introduced a significantly larger display paired with a larger, and more intuitive driver information center and gauge cluster.

In 2024, GMC trucks will now have an available 13.4″ infotainment touchscreen display, claiming the crown. Similar to Ford and GM’s displays, it will contain the popular split-screen capability, allowing using the control two separate aspects of the screen at the same time. This new center display is paired with a 12.3″ digital instrument cluster that is highly customizable and offers greater insight into vehicle operation. Denali Ultimate models also come standard with a 15″ head-up display where vehicle information is projected onto the windshield, allowing drivers to keep their eyes up and on the road.

It’s the Little Things

The Denali Ultimate interior features a multitude of intricate details that elevate these trucks’ luxury factor. Pictured here is custom engraving depicting topographical maps of Mt. Denali, the highest point in North America, and one of the world’s tallest mountain peaks.

The 2024 GMC Sierra 3500HD Denali Ultimate Exterior immediately distinguishes it from lower trim level. In contrast to the bright chrome trim and grille found on the 2024 GMC Sierra 3500HD Denali models, the Denali Ultimate features Vader chrome. It slightly resembles a Gunmetal Grey. Other key exterior characteristics include a signature Denali front grille, lower skid plate, and Vader chrome GMC badging. The Denali Ultimate exterior also has unique exterior fender badges displaying topography of Mount Denali, similar to what’s found on the interior.

2024 Sierra 3500HD trucks also benefit from some improvements made to all of their trucks for this model year.

The Denali Ultimate comes standard with power-retractable Assist Steps with LED perimeter lighting and bright accents.

What’s Missing? What Features does the Denali Ultimate Not Have?

It’s hard to ask for more features than what the 2024 GMC Sierra 3500HD Denali Ultimate already has. That being said, there are some noteworthy features present on Ford’s HD trucks and Ram’s HD trucks that could elevate the Denali Ultimate even further. Here are some suggestions for additional features that we see from some of the other manufacturers.

Features We’d Steal From the Ford Superduty

My personal truck, a 2022 Ford Superduty Lariat, features a panoramic, trim-panel moonroof. While this doesn’t do much for the truck’s capabilities, it’s a luxury feature that gives the truck an open, convertible-like feel. It gives the cabin a bigger feel, similar to a cathedral ceiling in a home. It’s also my son’s favorite feature of my truck, giving him a wide-open view of the sky. He’s extremely passionate about airplanes and it’s a great distraction while we’re taking roadtrips that will keep him occupied.

Another feature that GM could take from Ford is the addition of an upgraded powertrain. While the Denali Ultimate does come standard with the 6.6L L5P Duramax V8 Diesel engine, it’s the same engine that is found on the lowly PRO model. 2023 Ford F-350 Superduty Limited models contain an upgraded High-Output 6.7L Powerstroke V8 Diesel engine, offering 25 more horsepower and 150 lb.-ft more torque than the standard 6.7L Powerstroke Diesel engine. It’s just another differentiating factor that further separates the highest trim level from the lower ones.

Features We’d Steal from The Ram HD

Ram Heavy Duty feature an impressive suspension feature that is especially useful for those who tow frequently. The 2023 Ram 3500HD contains an auto-leveling air suspension that automatically levels the truck according to the load connected. It provides incredible ride quality when towing, but even unloaded, it provides a stark contrast to the typically stiff ride experienced on heavy duty trucks. On lighter duty models, like the 2023 Ram 2500HD, they come available with rear coil springs, which may reduce tow capacity a bit, but it does provide a less stiff rear end and improved driving feel when unloaded.

Comfort is obviously a driver factor in people’s decisions to buy luxury trucks. An upgrade like the Auto-Leveling Air Suspension would be fantastic improvement for families pulling campers or trailers that could make these trucks drive even better.

Overall Thoughts on the 2024 GMC Sierra 3500HD Denali Ultimate

The 2024 GMC Sierra 3500HD Denali Ultimate is in a class of its own. It offers consumers the most unique and luxurious GMC 3500HD date, boasting premium materials both inside and outside the cabin. Unlike previous top-tier Denali trims offering some degree of luxury, the Denali Ultimate offers a refreshing update on pickup truck luxury.

Instead of standard black leather seating, an alpine umber interior paired with Open-pore Paldao wood trim is used. Instead of the standard chrome or polished look of many luxury vehicles, the Denali Ultimate uses a darker Vader Chrome. Unbelievable attention to detail is also portrayed with personal touches like the engravings of topographical maps of Mt. Denali on the interior.

Unlike lower trims, the Denali Ultimate comes standard with the 6.6L L5P Duramax V8 Diesel engine. This gives buyers an engine that’s not only more powerful and responsive, but also a more capable towing machine. The L5P Duramax is partnered with the legendary 10-Speed Allison transmission.

The 2024 Denali Ultimate also benefits from a number of improvements made to all GMC trucks for this model year. A new, 13.4″ center display paired with a 12.3″ digital gauge display gives drivers a more connected and modern truck. The Denali Ultimate also comes standard with a 15″ Head-up display, allowing drivers to keep their eyes on the road.

Convinced? If you are shopping for a heavy duty pickup truck in 2023, the 2024 GMC Sierra 3500HD Denali Ultimate should be on your radar.
