2024 GMC Sierra HD AT4 Denali Release Date, Specs, and Price

Pickup lovers are going to get a treat in the form of a 2024 GMC Sierra HD AT4 Denali. This pickup belongs in the big boys’ category. They are by far one of the largest and meanest trucks on the market. This specific variant, AT4 is made for a bit of off-roading as well. And the Denali treatment is a well-known luxurious trim from GMC.

The Sierra HD is well known for the quality of ride and its towing and hauling capabilities. We believe GMC will translate the success of its predecessors to the all-new 2024 GMC Sierra HD AT4 Denali. It is still uncertain what kind of changes we are going to see in the new Sierra HD but we don’t expect too many changes under the hood. Most of the design tweaks will be in the cabin and on the exterior of the pickup.

GMC is trying to stay ahead of Ford and Ram by upping their game with this luxurious off-roading beast. Let us dwell deep and see what they have in store for us. We are sure people will be quite pleased with what is coming.


We are getting a lot of refreshments on the inside of the 2024 GMC Sierra HD AT4 Denali. Fans will be able to enjoy the luxurious and first-class feel that comes along with the Denali treatment. GMC is already putting a lot of effort to make their cabins comfortable and upper class.

Some manufacturers save money on the interior but that proved to be a mistake. Pickups aren’t just workhorses anymore, they are a statement, a way of life. So it makes sense to improve the interior and give passengers an enjoyable ride. This time they achieved it by basically borrowing the cabin from their SUV line.

2022 GMC Sierra HD AT4 Interior

The interior is spacious and can seat five people comfortably. This means a lot of headroom and legroom. There is also going to be leather upholstery, options of fabric and suede will be available as well. Contrast stitching with the seats will give a nice color scheme that buyers can choose from. Chrome or wooden accents would be a great addition. This would really increase the luxury aspect of the truck.

We can expect a large infotainment touchscreen in the middle, as is a standard nowadays in trucks. Most of the controls will be from here including air conditioning and drive modes. Expect a large screen since this is a Denali version after all. There will be some driving aids available in the form of artificial intelligence. Systems like these have been standard for the last couple of years and they save lives in difficult situations.

Don’t be surprised if you see some buttons and knobs so it is not all going to be digital. The dashboard could be, this would be a great step toward the future, and also it looks technologically advanced. Between the driver and the passenger, we get a nice comfortable cushion for an armrest.


Only small tweaks on the outside of the 2024 GMC Sierra HD AT4 Denali. The truck is already gargantuan and looks aggressive on the road. There is no need to drastically change the winning recipe. The truck has a huge front grille, it is wide and high and it is really a staple of the truck. Photos are taken from the official GM Instagram account, while spy shots are taken from the GMAuthority website.

Big GMC lettering on the front with huge C-shaped headlights. These are of course the latest LED technology to improve visibility and safety. The big side mirrors so you can keep an eye on the cargo you are towing. The back row of wheels is doubled since this is supposed to deal with the heaviest of loads. There are some headlights on the top of the truck but perhaps it gets changed into a unified LED bar. This would look more stylish for sure.

There are alternative materials like carbon and aluminum along the exterior. This will shave off weight and improve the power to weight ratio. Since this is the off-roading truck trim, we can expect beefier tires and some other additions to make it easier in the dirt. Adjustable air suspension and perhaps an increased ride height.

The cargo bed is of standard size, you will be able to fit a lot of stuff in the back. The tailgate has several options definitely. The tires are probably going to be from Goodyear and the wheel size is 20 inches. There still might be a few changes coming up but we will have to wait and see when the truck actually hits the road.

2024 GMC Sierra HD AT4 Denali Engine

The brand new 2024 GMC Sierra HD AT4 Denali will come with two powertrain options.

We get a 6.6-liter V8 gasoline engine that can produce 401 horsepower and 464 pound-feet of torque. This is more than enough to pull and haul the heaviest of cargo.

The other engine is a 6.6-liter turbodiesel V8 engine that comes with 445 horsepower and 910 pound-feet of torque.

Max towing capacity is 36.000 pounds there are no specifications for the hauling but we are sure that it will be good numbers. There is a choice between 6 and 10-speed automatic transmission.

The AT4 trim will include a locking rear differential and a transfer case with two speeds and a traction system straight from GMC. There is still no news about the hybrid or EV variant of the 2024 GMC Sierra HD AT4 Denali. But we suspect we won’t see those simply because EV isn’t at the point for towing and hauling capacity as is with the biggest of trucks.

2024 GMC Sierra HD AT4 Denali Price and Release Date

Starting price for the AT4 trim will be $62.000 and might go up depending on what amenities you want in your truck.

We could potentially see the 2024 GMC Sierra HD AT4 Denali hit the road in late 2023 or early 2024.
