2025 GMC Sierra 3500HD: Redesign, Release Date, Towing Capacity. The upcoming 2025 GMC Sierra 3500HD will get even better. This is a tough truck with great capabilities and it is a true workhorse. Furthermore, it comes with a certain amount of luxury, so the ride quality and comfort are excellent. Last year, General Motors revamped the entire Sierra HD lineup. As a result, we do not anticipate major improvements for 2025MY.
Sierra, in general, has excellent style and efficiency. There will be two powerful V8 engines available once again, in both gasoline and diesel versions. The new Sierra 3500HD truck will go on sale later this year, and here’s what you need to hear about it.
2025 GMC Sierra 3500HD Powertrain Specs
The same gasoline and diesel engine options are available in the next 2025 GMC Sierra 3500HD. The standard powertrain is a 6.6-liter gasoline V8 with 400 horses and 464 lb-ft of torque. The optional 6.6-liter V8 turbodiesel, on the other hand, is the real deal. This engine produces 445 horsepower and a whopping 910 lb-ft of torque.
A diesel engine that can haul up to 24,000 pounds is a must if you want a true heavy-duty work vehicle. And, although the diesel engine comes with a 10-speed Allison automatic transmission, the gasoline engine comes with a 6-speed automatic transmission.
2025 Sierra 3500HD Gets Mild Visual Upgrades
Minor cosmetic changes will be made to the forthcoming 2025 GMC Sierra 3500HD. This truck will maintain its rugged look while still sporting an aggressive exterior design. The majority of the truck, as before, is built around the smaller Sierra 1500 pickup. With its robust grille and modern LED headlights, the front fascia looks absolutely fantastic.
The headlights are marginally wider than before, and new 18-inch wheels will be on offer. As a result, this heavy-duty truck will wear a refreshed and sleeker styling. GMC has a variety of trim levels available, including the Black Diamond Edition. This version includes 20-inch high-gloss aluminum wheels, power-adjustable features, an LED perimeter lighting system. Reportedly, GM will reveal even more updates in the coming weeks.
Interior Changes
The latest 2025 GMC Sierra 3500HD will be slightly more refreshed on the inside. Again, the modifications are minor, however, they are necessary. You will have a two-seater or a three-seater with an eight-foot bed. This bed has an outstanding cargo space of 83.5 cubic feet. Nonetheless, the double cab layout offers five or six seats as well as a nine-inch bed with a volume of 69.5 cubic feet.
The most common alternative is the crew cab Sierra 3500HD, which has plenty of rear legroom. All models come standard with a seven-inch touchscreen. You can, however, upgrade to an eight-inch display for additional money. The range-topping Denali trim level is full of premium features and materials if you are into luxury.
2025 GMC Sierra 3500HD Release Date, Price
New 2025 GMC Sierra 3500HD will be priced at $38,500. Since the number of changes is minimal, there is a slight price increase. The Denali trim level costs $60,000, but fully-loaded Denali costs more than $70,000. As previously said, this truck will compete with the Ford F-350 Super Duty and Ram 3500.
