The upcoming 2024 GMC Sierra Heavy Duty is expected to receive a significant facelift. According to what we already know, the GMC will introduce a new front fascia and numerous modifications on the back. On top of that, the interior will gain a couple of upgrades and even changes under the hood are very likely.
The manufacturer postponed this model due to the pandemic, so major upgrades are the only way to go. This 2023MY will happen soon, and the 2024 Sierra HD should hit the roads next fall, per reports. It will be an exciting model so here is everything we know at the moment.
Spy Shots
The next 2024 GMC Sierra Heavy Duty spy photos have just surfaced. Since the prototype is heavily camouflaged, we don’t fully recognize the new design. We did observe that the front and rear portions appear to be brand-new, though. The face is significantly bigger, with new headlights and a new grille. The back part appears to have also gotten an overhaul with new tail lamps and a rear bumper.
Even the entry-level model has a pleasing and modern design. The luxurious Denali trim level, on the other hand, is extremely pricey and premium for a reason. Aside from the aforementioned improvements, the next model will also have new wheels, colors, and optional packages.
GMC Sierra Heavy Duty Interior
The cabin of the upcoming 2024 GMC Sierra Heavy Duty models is extremely comfortable because of the premium materials employed. Up until now, every Sierra HD featured a base 8-inch infotainment system that could be upgraded to a considerably bigger one. The truck has USB-C ports as well as phone hookups for Apple CarPlay and Android Auto.
Higher trim levels will, of course, have more standard equipment. Larger displays, enhanced Bose audio, leather upholstery, and other features are all included in the Sierra HD Denali model. Unfortunately, spy photos of the interior didn’t show much, though we anticipate a few substantial upgrades.
Towing Capacity, Transmission
The forthcoming 2024 GMC Sierra Heavy Duty is likely to use the same engine options as the outgoing model. However, a lot of sources claim that the truck will get additional power. A standard 6.6-liter V8 engine with 400 horsepower and 465 lb-ft of torque is available as standard. This engine has an RWD setup and a 6-speed automatic transmission.
According to the speculations, this gasoline unit will now produce about 450 horsepower. An optional 6.6-liter turbodiesel engine with up to 445 horsepower and 910 lb-ft of torque is optional. Only a 10-speed Allison gearbox with a diesel engine is offered. The standard engine has a towing capability of 18,500 pounds, while the optional diesel has a towing capacity of about 36,000 pounds. Those figures could increase in the future, although this is not official yet.
2024 GMC Sierra Heavy Duty Price, Release Date
From what we know, the new 2024 GMC Sierra Heavy Duty will start at $42,500 and move up from there. The lineup includes Sierra 2500HD and Sierra 3500HD models and the sales will most likely begin in the second half of 2023.
