2024 GMC Sierra: Is There A New GMC Sierra Coming Out? After undergoing a significant redesign for the 2022 model year, the Light-Duty Sierra 1500 version of the GMC Sierra is anticipated to have a series of incremental updates beginning with the 2024 model year.

In the meanwhile, the Heavy-Duty Sierra 2500HD and Sierra 3500HD models are scheduled to get a significant redesign for the year 2024. This redesign will include new designs for the front and rear ends, a new interior, and possibly improvements to the engine.

It is important to note that the revision of this product was supposed to take place during the 2023 model year; however, the product cycle has been delayed as a result of issues caused by COVID-19 as well as a lack of superconductor chips. In addition, the Sierra HD pickups of the fourth generation are now doing very well in the market arena.

2024 GMC Sierra Preview

It was just a matter of time until GMC joined in on the action when Chevrolet revealed that it will be releasing improvements to the Silverado HD in 2024. The Sierra HD will get a facelift for the 2024 model year from the dedicated truck brand of General Motors.

The revamp will include new external appearance, improved technology, and more robust powertrain choice. According to GMC, the new heavy-duty (HD) vehicles can give up to 975 pound-feet of torque and can tow up to 36,000 pounds when properly equipped. Additionally, these trucks can support loads of up to 36,000 pounds.

The GMC Sierra HD pickups are capable of pulling a Herculean amount of weight, but that’s not all they accomplish to live up to their Herculean name. These high-powered workhorses are also rather presentable, as they include chrome accents on the outside and a leather saddle that provides a pleasant ride on the inside.

The Sierra 1500 is a half-ton pickup, and its equivalent, the Sierra 2500HD and 3500HD, are jumbo-shrimp versions of the Sierra 1500. When compared to the Chevrolet Silverado HD lineup, the degree of luxury and quality found in these GMC trucks is far better. The standard powertrain consists of a 6.6-liter V-8 with 401 horsepower and a 10-speed automatic transmission.

However, in order to achieve the Sierra HD’s maximum conventional towing capacity of 22,500 pounds, an optional 445-horsepower Duramax turbodiesel V-8 with a 10-speed automatic transmission is required. Additional trailer assist features, such as Transparent Trailer View and Trailer Side Blind Zone Alert, as well as an optional adaptive cruise control system that works with trailering, allow the Sierra HD to work smarter rather than harder.

Despite the fact that the heavy-duty Sierra does not have the polish or maximum towing capacity of rivals like the Ram HD or the Ford Super Duty, it is a good option for anyone who has a truck-sized hole in their heart.

The front fascia and bumper of the 2024 Sierra HD from GMC have been updated with a new design for the model year. The grille is likewise all-new, and its design differs depending on the trim. The new pickup truck is equipped with dynamic light sequences that play as the driver approaches, exits, or starts the vehicle.

New wheel designs are being introduced for the SLE, AT4, and Denali grades, while dual-rear-wheel models will have 18-inch polished aluminum wheels. There are now a total of six new color options, and the highest-tier Denali and Denali Ultimate trims, when fitted with twin back wheels, get updated rear wheelhouse liners.

When you upgrade to the Denali Ultimate, you really get to show off your jewelry. It comes standard with chrome exterior trim and insignia that are exclusive to the Denali Ultimate trim level. Wheels with a gloss-black finish, side steps with power assistance, and GMC’s acclaimed MultiPro tailgate are all included as standard equipment.

It was only recently that the inside of the light-duty GMC Sierra 1500 had an upgrade, and now it is the time of heavy-duty vehicles. GMC states that the AT4, Denali, and Denali Ultimate receive a bump in the luxury sector, and that the SLE and SLT trims get completely redesigned interiors.

New color and accent choices are being made available for all vehicles, and GMC has noted that they are employing more quality materials to give the trucks a more sophisticated feel.

Full-grain leather and open-pore woods are standard on the Denali Ultimate trim level. Full-grain leather is used for the door panel coverings on GMC vehicles, and etched stainless steel grilles conceal the speaker placement.

The front seats of the truck are equipped with 16-way power adjustability and massage capabilities, and the inside of the vehicle has microsuede accents as standard. Every single pickup is equipped with a motorized sunroof, a rearview camera mirror, and Denali Ultimate emblems.

What’s New for 2024?

The most powerful truck offered by GMC has received a subtle exterior facelift in addition to bigger updates, including as a redesigned engine that provides the increased towing capability and an all-new grade level. The front fascia of the Sierra HDs has been updated, and they now have LED headlights and taillights that include sequential turn signals as optional extras.

Both the power and torque of the 6.6-liter Duramax turbocharged diesel V-8 have grown, now coming in at 470 horsepower and 975 pound-feet of torque, respectively. As a result of the boost in power, the towing capability of the whole array of Sierra 2500HD and 3500HD pickup trucks has improved, and the new maximum rating for the hitch is 22,500 pounds.

The six-speed automatic transmission that was formerly standard on the 401-horsepower, 6.6-liter V-8 gas engine has been swapped out with the Allison-certified 10-speed automatic transmission that was only available on the diesel engine. The popular Denali grade has been joined by an all-new Denali Ultimate trim, which is now available for both the 2500HD and the 3500HD.

This new trim delivers an even higher degree of luxury than its predecessor. In the same way as it does for the Sierra 1500, the Denali Ultimate adds leather wrapping to the door panels, steering wheel, and handles for the A and B pillars. Intricate leather stitching with a geographical map of Mount Denali in Alaska is added to the front seats, which are also power-adjustable in 16 different ways and come with heated and cooled messaging front seats.

These changes are reinforced by new trailering technology, which consists of adaptive cruise control when trailering, a gross combined weight (GCW) warning, and the fact that GM’s Transparent Trailer View is now also compatible with the gooseneck and fifth-wheel trailering. The driver assistance technology that comes standard on the Sierra HD has also been upgraded for 2024.

Customers have the option to upgrade to a camera with 14 angles and a trailer-length indicating system.

2024 GMC Sierra Competitors

Despite the fact that it is owned by the same parent company, the GMC Sierra HD is in the most direct competition with the Chevrolet Silverado HD, which is their cross-brand equivalent. Although both pickups share the same powertrains and many of the same technological features, the GMC is more comfortable and opulent than its competitor.

Ford has recently redesigned its heavy-duty vehicles, making them much more upmarket and tech-heavy. In addition, these trucks provide excellent technology for work and trailering. Last but not least, we can’t overlook the fact that Ram’s HD trucks come with very luxurious cabins, excellent ride quality, and robust capabilities.
