2025 GMC Sierra 3500HD Chassis, Interior, Price – According to speculation and leaks, GM will redesign the Silverado HD and Sierra HD trucks next year. The impending 2025 GMC Sierra 3500HD model has already been shown in various spy photos, and further details have subsequently become available. Even with all the covers, we could still see several improvements and alterations to the prior prototype, including a new style.
The most intriguing development is that this vehicle may also receive an update to a 6.6-liter Duramax diesel engine, which should result in more than 500 horsepower and 1000 lb-ft of torque. It’s interesting to note that the company will also update light-duty vehicles in addition to heavy-duty ones. All models should be made public sometime in 2019.
2025 GMC Sierra 3500HD Redesign
Exterior And Interior Design
The GMC Sierra 3500HD is scheduled to debut a number of improvements and modifications in 2025. According to what we have observed, the front and back of this vehicle will receive an updated external appearance. In comparison to the LED signature lights in the current model, the new LED signature lights are easier to notice and have a more organic design.
We also saw updated headlights with a larger grille and a four-light cluster. The truck has a new set of taillights on the back and the same tailgate and bumper as the previous model.
The new 2025 GMC Sierra 3500HD will be contemporary and roomy inside, similar to the light-duty trucks. The crew cab variant offers exceptional headroom and legroom. The inside design will change, though, depending on the trim level. The Sierra HD comes equipped with a large head-up display and an intuitive touch-screen infotainment system as standard.
If you enter the Denali version, expect additional comfort. Premium leather seating surfaces, contrast stitching, black metal trim, and open-pore wood are the focal points of this trim. The steering wheel, middle heap, and sill plates now have aluminum finishes thanks to the AT4, an off-road-oriented specification. Additionally, this model’s headrests include an AT4 logo.
2025 GMC Sierra 3500HD Engine
According to rumors, the next 2025 GMC Sierra HD may receive some engine improvements. The updated 6.6L Duramax V8 diesel engine, which generates 500 horsepower and 1,085 lb-ft of torque, will likely power the initial three-quarter- and full-ton trucks.
The new vehicle should be able to haul significantly more weight than the existing 36,000 pounds. The latest Duramax V8 has a 10-speed “Allison” mechanical information and makes 445 horsepower and 910 lb-ft of torque. In contrast, the Ram HD’s 6.7-liter Cummins I6 diesel engine generates 420 horsepower and 1,075 lb.-ft. of torque, while Ford’s 6.7-liter Power Stroke V8 diesel engine delivers 475 horsepower and 1,050 lb.-ft. of torque.
2025 GMC Sierra 3500HD Release Date And Price
The redesigned 2025 GMC Sierra 3500HD will have fresh looks and perhaps a better diesel engine the following year. If the engine rumors are true, the next model will be the first in its class to surpass the 500 horsepower mark.
But with all the improvements and adjustments, the cost of this truck can go up dramatically. Starting prices for the current model are under $70,000.
