The GMC Sierra HD family, which consists of the Sierra 2500HD and 3500HD, was fully overhauled (redesign and re-engineered) for the 2020 model year. Since then, the truck has been selling like hot cakes, with sales growing 23.2 percent to 73,777 units during the 2020 calendar year.

As well as the truck is performing in the marketplace, it’s not without a few downsides, which is why GM is working on a refresh. In fact, GM Authority was first to report that the Sierra HD will be refreshed, much like its Light Duty brother, one model year after the Sierra 1500. Today, we are bringing you the very first photos of the 2023 GMC Sierra HD refresh.
The prototype seen here is heavily camouflaged. In fact, everything to the front of the A-pillars and aft of the C-pillars is wearing a set of heavy vinyl camo. Going by the 18-inch steel wheels, this particular prototype is likely the Sierra HD trim – the base model within the lineup.
It also appears to be equipped with the X31 Off-Road Package, as per the knobby Hankook Dynapro MT2 tires, visible Rancho monotube shocks at the rear, and what seem to be underbody skid plates.
The front end of this 2023 GMC Sierra HD prototype features a set of placeholder headlights along with what looks to be a new grille. The rear end seems to retain the current model’s rear bumper, while gaining a new set of tail lights. It’s unlikely that the sheet metal on the box or the tailgate will change. The same goes for the BedStep, which was introduced in conjunction with the 2020 Sierra HD.
Even more importantly, the interior of this 2023 GMC Sierra HD prototype is completely covered, unofficially confirming that a new cockpit is on the way. That overhauled cockpit will feature an all-new center stack with a new screen running an all-new operating system.
It would not be completely out of question to expect an all-new digital instrument panel / gauge cluster, plus a host of other interior changes and improvements that should generally follow those of the 2022 GMC Sierra.
As an added bonus, we’ve heard that GM is working on updating the powertrain lineup for the 2023 GMC Sierra HD. We’ll have more on that, later.
Expect the 2023 GMC Sierra HD to launch in the second half of the 2022 calendar year as a 2023 model.
