The new 2024 GMC Sierra Heavy Duty will arrive next year, introducing a new look. As far as we know, the manufacturer will make this truck more attractive thanks to many changes and updates. First and foremost, the new truck will receive a refreshed exterior, interior, and trim level lineup, as well as a powertrain. Also, judging from the latest spy photos, it seems that the GMC Sierra Heavy Duty will get new turn signals.
So far, this truck has been offered a standard 6.6-liter V8 gasoline engine that produces 401 horsepower. However, thanks to some remapping, the new one should produce up to 450 hp. Optionally, you can still get the well-known 6.6-liter Duramax engine that makes 445 horsepower and 910 lb-ft of torque.
2024 GMC Sierra Heavy Duty Facelift
Despite the 2024 GMC Sierra Heavy Duty truck being heavily camouflaged, some interesting changes are visible. First of all, the upcoming truck has a refreshed front end, including a redesigned grille, revised headlights, and new turn signals.
The rear is also getting some changes, and we noticed better-shaped taillights and a new bumper. In general, it all depends on the trim level you choose. The most expensive is the Denali model, which makes this truck look more unique thanks to some modifications on the grille.
Very Comfortable Cabin
Like before, the upcoming 2024 GMC Sierra Heavy Duty will come with a very comfortable cabin made of high-quality materials. This model offers one of the most spacious cabins in its class, with enough room for up to five passengers.
On the technology side, we can make a safe assumption that the current touchscreen infotainment system of 8-inch will be replaced by a considerably larger one. It’s also important to note that Apple CarPlay and Android Auto are also standard, as well as USB-C ports. The upper trim Denali offers a more premium cabin, which includes a Bose sound system, leather seats, and more.
2024 GMC Sierra Heavy Duty Engine Specs
The engine lineup will not change for now, but some remapping will happen. So, the 2024 GMC Sierra HD should gain more power this time. In case you didn’t know, the standard model so far has been powered by a 6.6-liter V8 gasoline engine, producing 401 horsepower and torque of 464 lb-ft. This engine in the new model should produce up to 450 hp, which is great news.
It is also important to note that this engine continues to use a 6-speed automatic transmission, along with the standard RWD setup and optional AWD system. Optionally, you can get a proven 6.6-liter Duramax turbodiesel engine that develops 445 horsepower and 910 lb-ft of torque. This engine is paired with Allison’s 10-speed automatic transmission.
The petrol unit will reportedly be able to tow 18,500 pounds, while a more powerful diesel powertrain can tow around 35,500 pounds.
2024 GMC Sierra Heavy Duty Price, Release Date
The new 2024 GMC Sierra HD will cost around $43,000, which is compared to the current increase of $2,000.
Of course, if you choose the luxury Denali trim, the price will rise above $70,000. As for the release date, we expect the new truck to arrive in the second half of 2023.
