The next 2024 GMC Sierra 2500HD is going on sale next fall. This heavy-duty truck will receive a couple of important upgrades. However, we don’t know everything about this model right now. Still, spy shots are here, and numerous reliable reports are predicting various interior updates. Styling will get lots of refreshments and Chevrolet will also provide a higher level of comfort inside the cabin.
Moreover, Sierra 2500HD should offer more standard features this time. As before, this truck is available in numerous trim levels, editions, and packages. The performance could gain a small boost, although this is not official at the moment.
GMC Sierra 2500HD Redesign
The spy photos of the new 2024 GMC Sierra 2500HD are online, showing us the most recent cosmetic upgrades. For a start, the truck will wear new LED light signatures. Furthermore, the front fascia will introduce a revised grille. This front grille seems to be both wider and bolder than it is on the current model. To the sides, Sierra 2500HD will mostly remain.
However, sharper lines are expected, in addition to new exterior paints. The wheels are unchanged, but the rear section will get new taillight graphics, reportedly. With this nice mid-cycle facelift, Sierra HD will be more competitive, but let’s wait to see the final product.

Interior Changes
The upcoming 2024 GMC Sierra 2500HD is also getting various interior updates. The cabin will be improved, providing a couple of new amenities. From what we know, Sierra HD will gain more upright materials. Furthermore, a 13.4-inch infotainment touchscreen will be available, most likely as an option. As a result, installing a larger display also means that the button arrangement will be different.
A fully digital instrument cluster is on the way. As before, GMC Sierra 1500 pickup will have a big influence on the heavy-duty Sierra 2500. Of course, Sierra 2500HD will be less premium, but still satisfying and modern. We expect new safety aids to be offered as an option, so this truck will be impressive like never before.

Duramax Diesel Engine Gets More Power
In terms of performance, the 2024 GMC Sierra 2500HD will be slightly improved, per source. However, the engine lineup will remain intact. As a result, a 6.6-liter V8 gasoline engine remains the standard option, using a reliable 10-speed automatic transmission. Optionally, you can get a 6.6-liter V8 turbodiesel engine. It is a well-known Duramax powertrain, producing 500 hp and up to 1,100 lb-ft of torque.
In reality, torque figures will be lower. However, Sierra 2500HD will provide impressive performance, especially when equipped with optional diesel. We are waiting to hear more info regarding the truck’s towing capacity, mpg, and more.

2024 GMC Sierra 2500HD Price, Release Date
Thanks to the most recent upgrades, the price of the new 2024 GMC Sierra 2500HD will slightly go up. From what we know, this model will cost $44,000 and it will move up from there. On the other hand, the range-topping Denali trim level will cost over $70k. GMC will launch a new Sierra HD lineup next fall.
