The Top Features of the All-New 2024 GMC Heavy-Duty Truck
The new Sierra HD lineup offers an improved ride thanks to its updated suspension system and a more powerful engine and transmission. Inside the cabin, drivers and passengers can enjoy the latest technology features, including Apple CarPlay and Android Auto. The lineup also offers a host of convenience features, such as a power-sliding rear window, heated front seats, and a variety of storage options. With available towing packages, the Sierra HD lineup is designed to handle any job effortlessly.
Drivers can enjoy the raw power under the hood and impressive towing capabilities in all the available trims, which include Pro, SLE, SLT, AT4, Denali, and Denali Ultimate, with AT4X coming later this year.
Enhancing an already capable 6.6L V8 Duramax turbo-diesel engine with a 10-speed Allison transmission, the 2024 GMC Sierra Heavy-Duty truck ups its power delivery to 470 horsepower and 975 lb-ft of torque, which is an increase of 25 horsepower and 65 lb-ft of torque.
Chiseled, Bold, and Modern
To help facilitate the increase in horsepower, the 2024 GMC Sierra HD comes with an all-new, more efficient turbocharger to boost low-end torque. It also has increased power and torque, a new engine controller, 22-inch accessory wheels, and six new exterior colors.
The 14 available camera views with an enhanced transparent trailer view are accompanied by higher performance and power. The Trailer Side Blind Zone Alert is a crucial feature that helps improve awareness when pulling longer trails.
The Sierra 2500 HD crew cab can tow 21,900 pounds, increasing to 22,500 pounds with the optional Max Tow package, while the regular-cab short-bed remains unchanged with a towing capability of 36,000 pounds.
The Sierra Heavy Duty also offers Adaptive Cruise Control, which enhances the available Cruise Control with a front camera and adjusts the speed when following a vehicle using a following gap selected by the driver. It also accounts for additional drag and increased braking distance when pulling a load.
The 2024 Sierra Heavy Duty lineup offers a bold, chiseled look with elevated design elements inside and out. It offers a redesigned front bumper and new grills on each trim. The rear of the truck also showcases improved trail lamps.
The First Ever Sierra HD Denali Ultimate
Headlining the 2024 Sierra Heavy Duty lineup is the first ever Sierra HD Denali Ultimate, a heavy-duty truck that combines the power of the Sierra HD with premium-quality and style. From the grille to the gate, the Denali Ultimate demands respect. Furnished with a redesigned Denali signature grille, new LED projector headlamps, and high-end 20” ultra-bright machined aluminum wheels with high gloss black accents, the Denali Ultimate is an elegantly sculpted machine.
Inside, the exclusive Alpine Umber interior comes with full-grain leather seats, door panels, a center console lid, and grab handles that exceed the standards of even the most detailed luxury seeker.
