Among heavy-duty pickups, the 2025 GMC Sierra 2500 HD has gained a reputation for reliability in different driving conditions, muscular engines and towing, and innovative technology features that can enhance both work and play.
Strong Engines and Towing
This edition’s two engines are both 6.6-liter V8s, though one is a diesel engine and the other is gas-powered. The gas engine provides 401 horsepower and 464 pound-feet of torque, more than enough to tackle heavy workloads. This engine also tows up to 18,700 pounds when the truck’s fully equipped. The diesel engine takes everything to the next level, generating 470 horsepower and 975 pound-feet of torque while lending the truck a best-in-class maximum towing capacity of 22,070 pounds.
Capable Off-Road Versatility
Also versatile in different driving conditions, this truck offers an available 4×4 system that provides reliable traction. You can also enhance the truck’s versatility even more with a variety of off-roading options, including Multimatic DSSV dampers and an off-road-ready suspension system for smoother rides and an automatic-locking rear differential for more traction.
A Tough, Work-Ready Design
Designed for tough challenges, this edition’s exterior offers multiple tailgate options, with the Pro and SLE trims featuring a conventional locking tailgate and all other trims coming with the MultiPro Tailgate. This tailgate’s multiple functions include different gating options and a drop-down step with available step lights. There are also LED lights available for the bed, and select trims have power-retractable assist steps with LED perimeter lighting. Multiple tonneau cover types are also available, as are vertical trailering mirrors.
Comfortable on the Inside
Inside the cabin, the front seat is a 40/20/40 split-folding one with under-seat storage, while two-row Double Cab and Crew Cab models have a 60/40 split-folding rear bench seat as well. While lower trims have cloth seating, select upper trims offer many high-end fabrics, like leather in Dark Walnut/Slate and provide power-adjustable heated driver and front passenger outboard seats and a heated steering wheel while also offering available heated rear outboard seats.
Advanced Tech and Safety
Standard technology and driver-assist highlights include the GMC Infotainment system, a Wi-Fi hotspot (which can be used with a data plan), Lane Departure Warning, Forward Collision Alert with Automatic Emergency Braking, Hitch Guidance, and the HD Rear Vision Camera.
