The 2024 Chevrolet Silverado HD made its debut in September 2022, so it was inevitable before the GMC Sierra HD got a comparative round of updates. Revealed online, the truck acquires a new-look design and an all the more impressive turbodiesel V8, among different changes.

GMC developed the Sierra HD essentially for towing and pulling so the main changes are tracked down under the hood. The accessible 6.6-liter turbodiesel Duramax V8 engine presently creates 470 horsepower at 2,800 rpm and 975 pound-feet of torque at 1,600 rpm, figures that represent increments of 25 and 65, respectively, over the 2023 model and that match the 2024 Silverado Hd’s. GMC notes it expanded low-end torque by around 25% by fitting a new turbocharger. The V8 turns the rear or the four wheels by means of a 10-speed automatic transmission.

On the gasoline side of the spectrum, the 6.6-liter V8’s output stays flat at 401 horsepower and 464 pound-feet of torque. It’s presently rushed to a 10-speed automatic transmission, and supplanting the 2023 truck’s six-speed allows the engine to run nearer to its peak power for longer periods. Here once more, back tire drive comes standard and a part-time four-wheel-drive system is accessible across the whole line-up.

Appropriately prepared, the 2024 Sierra 2500 HD Crew Cab can tow as much as 21,900 pounds. The standard 2500 HD’s towing capacity checks in at 22,500 pounds (a 4,000-pound improvement), and the 3500 HD is capable of towing as much as 36,000 pounds — that is almost 13 Subaru BRZs.

Purchasers have a dizzying selection of trim levels and body styles to look over. The range incorporates Regular, Extended, and Crew cabs as well as seven trim levels called Pro, SLE, SLT, AT4, AT4X, Denali, and Denali Ultimate, respectively. The AT4X variant won’t be accessible at launch, and the Denali Ultimate is new for the 2024 model year. Moreover, 3500 HD models can be ordered with dual rear wheels.

What the truck resembles relies upon the trim level. Broadly speaking, designers drew a more angular front end with a new-look grille, sharper-looking lights, and a redesigned bumpe. New wheels are important for the update also; the 3500 HD dually gets 18-inch polished aluminum wheels, and 22-inch units are optional on single-rear-wheel trucks. At long last, the color palette develops with six optional shades called Titanium Rush Metallic, Sterling Metallic, Volcanic Red Tintcoat, Redwood Metallic, Meteorite Metallic, and Downpour Metallic, respectively.

Essentially, not every 2024 Sierra HD is made equivalent on the inside. Pro models remain basic, SLE and SLT trims get a specific interior, while AT4, Denali, and Denali Ultimate versions benefit from a more upmarket cabin. A few models are accessible with a similar basic 13.4-inch touchscreen found in the Silverado, a 15-inch head-up display, and a 12.3-inch digital instrument cluster. GMC makes a long list of electronic driving guides standard, including Front Pedestrian Braking (which is new for 2024) and lane departure warning, and various trailer-specific technologies are accessible, for example, gooseneck-compatible Transparent Trailer View and Gross Combined Weight Rating Alert.

The new-for-2024 Denali Ultimate slots at the top of the range. It comes standard with the 6.6-liter turbodiesel V8 as well as a trim-specific grille, 20-inch machined-aluminum wheels with high-gloss black accents, and specific exterior emblems that highlight a rendering of Alaska’s Mount Denali, which at 20,310 feet stands pleased as the tallest peak in North America. The Denali Ultimate likewise gets power-operated running boards, leather upholstery, wood interior trim, massaging front seats, and a Kicker sound system. It sounds luxury sedan-like.

The 2024 GMC Sierra HD will reach dealer lots across the nation in the first quarter of 2023, and deliveries of the off-road-focused AT4X model are scheduled to begin later in 2023. Pricing data for the full range will be declared nearer to the truck’s on-sale date.
