Engine Options
The Sierra 2500 comes with a 6.6L V8 gas engine that generates 401 horsepower at 5200 rpm and 464 lb.-ft. of torque at 4000 rpm. This engine is combined with an Allison 10-speed automatic transmission that includes Tow/Haul mode for smooth shifting and auto-grade braking to slow the truck on downhill grades and reduce brake wear.
The available 6.6L Duramax Turbo-Diesel option offers even more stamina and power, yielding 470 horsepower at 2800 rpm and 975 lb.-ft. of torque at 1600 rpm. This engine offers a maximum towing capacity of 22,070 pounds and is also paired with an Allison 10-speed automatic transmission.
Exterior Features
The 2500 is a full-size pickup with durable exterior features that make it great for tough jobs. This includes the 12 tie-downs that are rated at 500 pounds per corner, securing the heaviest cargo while hauling. The Sierra’s cab-mounted cargo area lamps are another convenient feature, providing ample lighting when you’re working in the dark.
Additional exterior features on the Sierra 2500 include animated LED projector headlamps with LED turn signals and daytime running lamps. The solar-absorbing glass windshield blocks out strong solar rays from the sun, keeping your cabin cooler and protecting certain interior elements from fading. For easier cargo access, the SLE and higher 2500 trims come with a GMC MultiPro tailgate that has six possible configurations.
Seating Configuration
There’s seating for six passengers inside the Sierra 2500, with a 40/20/40 split front bench and a 60/40 split rear bench. The Sierra’s front bench has an under-seat storage compartment that offers the perfect space for extra work tools, while the rear bench can be folded up to create more cargo space on the floor.
Tech Functions
The 2024 Sierra 2500 has a 7-inch multi-touch display with AM/FM stereo, Apple Carplay, Android Auto, and more. This Infotainment system makes every ride more enjoyable and convenient, allowing you to sync your phone to the truck for hands-free phone calls. If you purchase a Sierra 2500 SLE or higher trim, you’ll even get a free 3-month trial subscription to SiriusXM radio for hundreds of music, news, and sports stations on your GMC Infotainment system.
