What kind of vehicle is the 2024 GMC Sierra 2500HD? What does it compare to?
The 2024 GMC Sierra HD is a full-size, heavy-duty pickup that shoulders up against other big rigs such as the related Chevrolet Silverado 2500HD, as well as the Ram 2500 and Ford F-Series Super Duty.
Is the 2024 GMC Sierra 2500HD a good truck?
Capable, comfortable, and unabashedly block shaped, the GMC Sierra 2500HD and 3500HD come in three cab sizes, two bed lengths, two powertrain options, and essentially seven trim levels. In short, there’s a configuration for anyone who plans on towing 10,000-pound loads or more on the regular. It earns a TCC Rating of 7.0 out of 10, though safety and fuel economy ratings—where these trucks perform worst—are incomplete so the rating skews high. (Read more about how we rate cars.)
What’s new for the 2024 GMC Sierra 2500HD?
The redesigned heavy duty follows in the big and broad tracks of the related Chevrolet Silverado HD, but GM distinguishes them a bit more with two new trims this year in the AT4X off-road rambler and the ultra-luxe Denali Ultimate grade.
The blocky freight-train ends wear new bumpers, and a few new wheel designs grace the sides of this big boy, which comes with standard or long beds, as well as regular, extended, or crew cabs. Excluding the Pro, every Sierra HD gets the brand’s 6-way power liftgate as well as side and corner bed steps that make getting up and out of the beds a bit easier.
The big changes come inside, with a 12.3-inch instrument cluster and 13.4-inch touchscreen standard on all but the Pro models. Buttons and dials still simplify the controls, and a column-mounted gear shifter remains, so the Sierra 2500HD hasn’t gone all digital.
The 6.6-liter gas V-8 carries over, but GMC swapped out the 6-speed for the Allison 10-speed automatic also used on the revamped turbodiesel. With a new turbocharger and boosted output to 975 lb-ft of torque (up from 910 lb-ft), the 6.6-liter turbodiesel V-8 results in quicker passing moves and more power throughout the band. Towing peaks at 36,000 pounds for the 3500HD dually with rear-wheel drive, but even the diesel 2500HD with a crew cab can tow more than 21,000 pounds.
The crew cab models have more interior space than other passenger vehicles. The versatile seating has hidden storage underneath and storage pockets in the rear seat backs to let occupants lose stuff in a variety of places.
In addition to the standard trailering packages and the 14 available camera views, the redesigned heavy is safer on roadways for all users. Standard driver-assist tech includes automatic emergency braking with pedestrian detection at speeds under 50 mph, lane-departure warnings, and automatic high beams. Mid-level and above trucks get blind-spot monitors, which are key for a vehicle this long, as well as dual truck and trailer side mirrors.
How much does the 2024 GMC Sierra 2500HD cost?
The 2024 GMC Sierra 2500HD costs $48,200, including a $1,895 destination fee. That’s for the Pro regular cab with a long bed and several towing features. It escalates from there with SLE, SLT, AT4, AT4X, Denali, and Denali Ultimate trims.
SLE and above grades come well equipped with a 12.3-inch digital instrument cluster and a 13.4-inch touchscreen with wireless Apple CarPlay and Android Auto connectivity. At the other end of the spectrum is the new Denali Ultimate, with features ranging from a 15.0-inch head-up display to a built-in Kicker audio system in the 6-way power tailgate. It’s $95,000.
