2025 GMC Sierra 2500 HD Overview
The 2025 GMC Sierra 2500 HD seamlessly blends rugged durability with sophisticated design. While it has a sturdier chassis and more potent powertrains than its counterpart, the Sierra 1500, it echoes the same ethos: a luxury vehicle with no limits on performance. The Sierra HD offers an extensive range of choices for discerning buyers. For those keen on adventures, the AT4 models stand ready, while opulence finds its zenith in the Denali Ultimate. Buyers looking for a powerful pickup loaded with creature comforts should take a good look at the 2025 GMC Sierra 2500 HD at dealers like the Marion GMC dealer.
For 2025, adaptive cruise control with trailering assist, previously exclusive to the 2024 AT4X and Denali Ultimate trims, is now also standard on the AT4 and Denali models. Additionally, the trailer-brake controller is now included across all trims, eliminating the need to add it separately on lower trims. According to the Marion GMC dealership, front and rear parking sensors are also available on the base Pro and SLE trims as part of the Pro Safety Plus package.
The reviewers at Kelley Blue Book give the 2025 GMC Sierra HD high marks, writing: “As appropriate pulling up to the valet stand at a 5-star restaurant as it is hauling bricks to the job site or pulling a boat to the lake, the 2025 GMC Sierra HD is a workhorse, doubling as a show pony for date night and family outings. Capable of tugging up to 36,000 pounds when properly outfitted, it doesn’t shy away from the tough jobs but can be downright luxurious in its Denali and Denali Ultimate trims.”
The 2025 GMC Sierra 2500 HD is offered in seven trim levels: Pro, SLE, SLT, AT4, AT4X, Denali, and Denali Ultimate. It comes standard with a 6.6-liter V8 engine delivering 401 horsepower and 464 lb-ft of torque, teamed to a 10-speed automatic transmission. Buyers can choose between rear- and four-wheel drive. For those seeking more power, an available 6.6-liter Duramax turbodiesel V8 produces 470 hp and an impressive 975 lb-ft of torque. This unit is paired with an Allison 10-speed automatic transmission and has a maximum towing capacity of 22,500 pounds.
The interior of the Sierra 2500 HD combines luxury with practicality. Every model comes with spacious front seats, ensuring comfort for drivers and passengers alike. There’s plenty of legroom to keep passengers comfortable on longer trips, and the Crew Cab offers the added convenience of under-seat storage.

The interior becomes increasingly luxurious as you move up the Sierra HD’s trim levels. The SLT and higher trims feature perforated leather seats, while the AT4 boasts Jet Black and Kalahari accents for a distinctive look. The interior is even more refined in the Denali trim, with exclusive leather and open-pore wood trim for a touch of elegance.
At the top of the lineup, the Denali Ultimate trim stands out as one of the most luxurious trucks in its class. It includes high-end features such as massaging front seats, a microsuede headliner, and a 12-speaker Bose audio system.
