2024 GMC Sierra HD Preview: New Tech, New Interior, Same Mission

Hit Agents: early 2023

Looks like a big truck

Big truck owners love the look of big trucks, and the new Sierra HD won’t disappoint. The front end of the new model year has been modified with new headlights, grilles, bumpers and rims, and trim levels are Pro, SLE, SLT, AT4, AT4X, Denali and Denali Ultimate.

As this has become a common feature on many new GM vehicles, a new light motion occurs when the truck is approached, started, or turn signals are used. There are some new wheel designs for SLE, AT4 and Denali, as well as larger 18-inch forged-aluminum wheels available on the 3500 models with twin rear wheels — and if you like, you can even select new 22-inch wheels for even more exaggeration. The Sierra HD also has six new exterior color options (for the extra cash, of course): Titanium Rush Metallic, Sterling Metallic, Volcanic Red Tintcoat, Redwood Metallic, Meteorite Metallic, and Downpour Metallic. Finally, rear wheelchair bushings will be standard equipment on Denali and Denali Ultimate.

More power never hurts

The 2024 Sierra HD will be a standard 6.6-liter V-8 that produces 401 horsepower and 464 pound-feet of torque. That engine continues mostly unchanged from the 2023 model year, but is now paired with a standard heavy-duty Allison 10-speed transmission; The old six-speed car is gone. This gives the truck four more forward gears to play with, with smaller steps between gears allowing for more precise control of engine output and speed. The optional 6.6-liter Duramax V-8 produces 470 horsepower and 975 pound-feet of torque, an improvement over the Duramax outboard’s 445 horsepower and 910 pound-feet of torque. The engine has also been recalibrated to increase lower torque by 25% to improve towing performance, according to the company.

That towing performance is also set to increase, with GMC now saying the Sierra 2500 2WD Crew Cab Long Bed will be able to tow up to 21,900 pounds via the hitch, and a maximum towing capacity of 2,500 pounds is 22,500 pounds — a 4,000 pound increase over the 2500 pound current – when specially configured for this purpose. Do you want to have the greatest towing capacity possible? The new Sierra 3500 2WD Regular Cab Long Bed Twin with Gooseneck Hitch can weigh 36,000 pounds.

But the towing capacity has not only been enhanced. GMC says it has added a range of new technologies to the Sierra HD to enhance ease and confidence in towing situations. They all focus on GMC’s ProGrade Trailering system, which the company says offers all kinds of improvements from 14 different possible cam views to what it says is an industry-exclusive transparent trailer view for rear- and fifth-wheel trailers. Put a camera in the back of the trailer, hook it up to the ProGrade system and the tech wizard will stitch together the images to make the trailer disappear into the truck’s display, letting you see behind the trailer as you drive.

Among the 14 possible cam views (which naturally require some accessory cams to be installed on the trailer), there is a hitch steering with hitch width that helps you align the towball with the receiver; Bed width with zoom steering and bed hitch connection to assist with gooseneck or fifth wheel attachment; Rear side view with trailer length indicator, adding a special length indicator in the side cam view showing where the trailer is only relative to surrounding obstacles. It’s an impressive system that does some of the things the newer Ford Super Duty can’t, but falls a bit short on other things Ford Can an act.

There’s also a new trailer side blind zone alert that extends from the warning zones around the trailer, and a new alert that warns the driver if the vehicle and trailer weight exceeds the Sierra HD’s combined gross weight rating. A recent update to the truck’s adaptive cruise control system makes it possible to operate while towing as well, taking into account the trailer’s weight and towing while in motion.

Even more luxurious than before

GMC took the opportunity to evolve its top truck to extraordinary new levels, with new interiors for all trims and upgraded material quality on the top Denali and AT4. A new 13.4-inch landscape-oriented touchscreen is available in the center console, which GMC says is the largest in its class; It augments the optional 12.3-inch digital instrument cluster. The large screen can be customized to user preferences, and in all but the base Pro grade it will run Google’s new built-in which has proven somewhat problematic in other examples we’ve tried. are the standard.

For 2023 there is a Denali Ultimate package that you can add to the Denali equipment level – but for 2024 there is a specific Denali Ultimate cutting level Which sits atop the Sierra HD range. It comes with some unique exterior details like the dark chrome “Vader” grille and decals, 20-inch aluminum wheels with black accents, fender badges that mimic the terrain of the Denali Mountain map, electric assist side steps and a six-way MultiPro Tailgate with integrated Kicker audio system.

Inside, the Denali Ultimate gets the truck’s luxury treatment starting with a unique Alpine Umber color scheme, full-grain leather accents, and real paldao wood trim. The front and rear seat panels, door panels, center console lid and front and rear seat grab handles are all wrapped in leather. The front seats are adjustable in 16 positions with massage, and the suede material for the roof lining extends under the A- and B-pillar trim, as well as the visors. The Denali Ultimate will also have a Bose luxury 12-speaker audio system, a rear-view camera mirror, a 15-inch multi-color display and a standard power sunroof.

Pricing and availability

We won’t have any prices for the new 2024 GMC Sierra HD until after the truck’s sale date approaches, which GMC says will come out in early 2023. The AT4X won’t reach the level of the AT4X at launch either; It will come later in 2023, according to the company. With the newly updated Ford Super Duty 2023 slated to launch soon, next year looks set to be a busy year for evaluating the updated big trucks.
