We’ve already seen a few spy photos of the anticipated 2025 GMC Sierra 3500HD model, and there’s been more details since that time.

The most exciting thing is the possibility that this vehicle will be upgraded to a 6.6L Duramax Diesel engine upgrade which could result in more than 500 horsepower or 1000 lb.-ft. In addition, to heavy-duty models, the company will also make upgrades to light-duty trucks. The models will be unveiled in the coming year.

Exterior and Interior Design
Its 2025-year-old GMC Sierra 3500HD is set to release a number of new features and modifications. From what we’ve observed, this model will get a revised appearance at both the rear and front. The LED signature lights that are new are evident and have a more natural design, and appear more bright compared to the model’s current LED signature.
We also saw new headlights, which now feature an all-four-light cluster, as well as a larger grille. On the rear, the truck is equipped with an updated set of taillights and has the same bumper, tailgate, tailgate bumper as the previous model.
Similar to those light-duty trucks, the GMC Sierra 2025 3500HD will be sleek and large inside. When you select one of the Crew Cab models, you’ll enjoy spacious legroom and headroom. But, based on the model’s trim level, the layout inside the cabin will differ. The Sierra HD offers a large head-up display as well as an intuitive touch-screen infotainment system.

The trim is highlighted by premium leather seats and contrast stitching along with dark-colored aluminum trim as well as wood with open pores. The AT4 model, which is an off-road-oriented trim, includes aluminum finishes for the steering wheel and the center stack along with sill plates. The headrests on this model sport the AT4 logo.
