2020 GMC Sierra 2500HD: Preview, Pricing, Release Date

, Automotive Editor - January 25, 2019

Model Preview

The third-generation GMC Sierra 2500HD debuted only a few years ago in 2014, but with the truck segment rapidly changing, GMC saw it fit to release a redesigned Sierra 2500HD. The 2020 GMC Sierra 2500HD will include an all-new look, an updated powertrain, and a huge focus on tow-friendly technology.

Visually, the 2500HD won’t be a huge departure from the current model, but it will have distinct differences. The most striking changes will be up front where it will boast a taller hood line, hood scoop, massive grille, bold LED headlights, and prominent LED “light blade” daytime running lights. Around back, there will be new LED taillights, a new six-function tailgate, and a 1-inch-lower lift-in height for easier loading and unloading.

Inside, the 2500HD will gain an all-new look and best-in-class leg and head room in the Crew Cab model. It will also gain a higher driver’s seating position for enhanced visibility, an ergonomically designed cabin, and a class-exclusive head-up display.

Buyers looking for a heavy-duty truck that can work and play will appreciate the Denali model. This upscale pickup will gain premium leather seating, authentic open-pore wood trim and dark-finish aluminum decor to up its style and luxury.

Under its hood, the 2020 GMC Sierra 2500HD will feature a 6.6-liter turbo-diesel engine that will pump out 445 horsepower and 910 pound-feet of torque. This engine will pair with a standard 10-speed Allison automatic transmission. This powertrain will combine with the Sierra 2500HD’s rugged platform to deliver over a 30,000-pound towing capacity. The current Sierra 2500HD also has a standard 6.0-liter gasoline-fueled V8 engine, but GMC has mentioned nothing other than the diesel engine to date.

Speaking of towing, the 2020 Sierra 2500HD will also have loads of tech to make towing easier. This will include 15 camera views like the transparent-trailer view that uses a series of cameras to make the trailer transparent to allow the driver to see what is behind and to the sides of what they are hauling. The iN-Command app will allow the driver to monitor key camper details, including water and sewage levels and fuel levels in generators, and it can even turn on the water heater.

Buyers looking for a truck with off-road credentials will have the AT4 model with its off-road suspension skid plates, Eaton locking rear differential, 18-inch wheel slathered in all-terrain rubber, Off-Road mode, hill-descent control, and more.

The IIHS hasn’t tested the current GMC Sierra 2500HD, but the federal government gave it a four-star overall rating. The jury is still out on the 2020 Sierra 2500HD’s advanced safety tech as we wait to find out what equipment it will feature. We expect it to at least carry on with what the current model offers, which includes available forward-collision warnings, lane-departure warnings, and front and rear parking sensors.

Pricing & Release Date

The 2020 GMC Sierra 2500HD will arrive in showrooms in late summer 2019.

Pricing is not available on the 2020 GMC Sierra 2500HD yet, but we expect a bit of an increase over the current model’s MSRP range of $39,695 to $61,295 (destination fees included).

The 2020 GMC Sierra 2500HD will compete against the Ford F-250, Ram 2500, and Chevy Silverado 2500HD.
