2024 GMC Sierra HD Unveiled With New Design

Competition in the big-capacity, the full-size truck segment is as fierce as it is in the 1500 class. After Ford unveiled the next-generation Super Duty, and Chevrolet announced changes to its Silverado HD, is GM‘s turn to launch its 2024 Sierra HD. On the menu, are new versions, a revamped interior, and aesthetic improvements.

2022 was the model year in which the Denali Ultimate and AT4X trims debuted in the 1500 series. It was only a matter of time before the HD series got them, and it will be for the 2024 model year.

The Denali Ultimate is the one that sits squarely at the top of the range, even more, luxurious than the Denali. The use of full-grain leather for the door panels, dashboard, and seats, 16-way massage seats, 12-speaker audio system, 15-inch head-up display, and rear-view mirror camera are some of the features added by this level of equipment. Outside, exclusive 20-inch wheels and some unique “Vader chrome” color accents are also included, as is the MultiPro rocker panel.

Very few details are however revealed on the AT4X, given the fact that it will arrive after all the other versions. As is the case with the Sierra 1500, hopefully, this build will be the pinnacle of the regular AT4 build. The equipment will be abundant on board and some additions will be made in terms of mechanics, to improve off-road capabilities.
