The HD series, which includes the Sierra 2500HD and 3500HD variants, was completely redesigned last year. Sales have increased significantly since then. The GMC Sierra 2500HD, like its Chevrolet Silverado HD sibling, is one of the most recent heavy-duty trucks on the market.
The new model has a substantially disguised front and back fascia. Both ends are redesigned front, according to the latest spy shots. Aside from exterior modifications, the manufacturer will also deliver some inside improvements. We may anticipate a fully redesigned interior with modern technology and more upright materials. As before, Sierra 2500HD offers two powertrain options, including potent V8 turbodiesel engine.

2025 Sierra 2500HD Spy Shots
As for the design, the upcoming 2025 GMC Sierra 2500HD definitely looks more appealing and more modern. The front fascia is unique thanks to red GMC letters on upfront. Thanks to that, this heavy-duty truck will stand out from the crowd. Its enormous proportions also add to more attention-grabbing design.
This truck’s front end is outfitted with LED headlights, distinctive C-shaped LED strips, and daytime running lights. The range-topping Denali trim level, on the other hand, offers a more athletic appearance with a grille that features more chrome. All dual-rear-wheel Sierra HDs and Denali models come equipped with impressive roof lights. The spy shots are showing significant upgrades on both front and rear ends. We expect new exterior features and possibly new exterior colors.

Interior will also gain numerous refreshments. The forthcoming 2025 GMC Sierra 2500HD will arrive as a more modern truck with higher level of comfort. The Crew Cab variant has a lot of headroom and legroom. In general, there is enough space for five passengers to sit comfortably. On the other hand, technology is always evolving, and there are several new devices available.
All Sierra HD trucks come standard with a large head-up display (HUD) and an easy-to-use 8-inch infotainment touchscreen. The Denali variant is the most luxurious one, owing to its leather upholstery, contrast stitching, chrome accents and dark aluminum trim. The AT4 model, which is designed for off-road use, is also available and it also provide a lot of premium stuff.
