◾Enhanced off-road capability matched with available 18,500-pound max trailering1

◾Offers the most trailering tech in its class2 and first-class luxury features

◾Specialized AEV Edition offers extreme capability and confidence off-road

DETROIT – GMC first elevated key off-road truck segments with the premium and capable Sierra 1500 AT4X and Canyon AT4X. Today, GMC announced the next step with the first-ever 2024 GMC Sierra HD AT4X — featuring the Sierra HD AT4X AEV Edition — a truck that enables adventurers to go further while still having the towing capability essential for heavy duty haulers.

The Sierra HD AT4X bolsters GMC's lineup of premium off-road trucks, balancing increased off-road capability, smooth on-road handling, offering the most trailering technology in its class2 and first-class luxury and comfort features.

'GMC's AT4X trim, which will be available across the entire GMC truck lineup, offers customers more premium choices when it comes to 'do-it-all' capabilities,' said Duncan Aldred, global vice president, Buick-GMC. 'Each model delivers unique strengths, with the all-new Sierra HD AT4X taking it to the max, giving our customers the most luxurious and most off-road capable HD we've ever offered. AT4X means you can conquer almost any terrain, in complete comfort and with the towing power to bring your recreational toys, gear or camper along for the adventure.'

AT4X: Premium off-roading the GMC way

Building on the foundation of the revamped 2024 Sierra HD, which receives fresh design updates, new available premium interiors and an all-new tech-focused layout, the new Sierra HD AT4X's highlights include:

◾Available 18,500-pound max trailering capacity1

◾Factory-installed 1.5-inch (38mm) suspension lift

◾Multimatic DSSV dampers

◾Rear e-locking differential

◾35-inch Goodyear Territory tires

◾Specific front upper and lower control arms and specific steering knuckles

◾Larger steel transfer case skid plate and front aluminum skid plate

◾Unique Obsidian Rush interior featuring premium appointments like massaging, full-grain leather-wrapped front seats

The Sierra HD AT4X also includes a new Off-Road Mode. When engaged, the Off-Road Mode adjusts various vehicle calibrations, such as the anti-lock brakes, traction control and stability control, to provide optimized performance when venturing off-road. Additionally, Off-Road Mode alters throttle progression and transmission shifts to allow for better off-road control and performance.

Extreme AEV Edition

The available AT4X AEV Edition adds robust stamped steel bumpers with integrated recovery points and front winch capability which provide additional driver confidence and protection. It also features heavy duty steel skid plates that help keep vital components such as the steering gear and transfer case protected on the trail. Additional features include unique 18-inch Salta wheels and unique exterior badging and interior cues.

'The Sierra HD is an ideal foundation when it comes to on-road performance, off-road capability and insane pulling power,' said AEV CEO and founder Dave Harriton. 'As with the Sierra 1500 before it, we took AEV's signature performance-driven approach and dedication to detail to elevate the aspects that off-road customers want and demand in their heavy-duty truck. The result is an awesome truck with capability and confidence in all the right spots.'

Heavy Duty capability: Turbocharged pulling power

In addition to the standard 6.6L gas engine, the new AT4X offers the turbocharged pulling power of the available 6.6L Duramax Turbo-Diesel. Enhanced for 2024, it will deliver 470 horsepower and 975 lb-ft of torque, offering more power across the entire operating speed range.

Both engines are paired with an Allison 10-speed automatic transmission, which is designed to optimize engine power, torque and efficiency.

Confidence-inspiring trailering tech

Along with the rest of the 2024 Sierra HD lineup, the new AT4X offers the most trailering assistance technologies in the heavy-duty class2 as well as the available ProGrade Trailering System.

It includes a suite of available intelligent assistance technologies designed to help streamline the hitching and towing process, with integrated tools that can help enhance customers' safety and confidence, including available enhanced, industry-first Transparent Trailer View4 for Gooseneck and Fifth Wheel Trailering, available Trailer Side Blind Zone Alert5 and new, available Adaptive Cruise Control5 with Trailering.

Additionally, there are up to 14 available camera views6 including Hitch View, Bed View with Zoom and Bed Hitch Guidance, and Rear Side View with Trailer Length Indicator.

First-class interior luxury and comfort

The first-ever Sierra HD AT4X offers the luxurious appointments and comfort in a premium, off-road-capable HD pickup, with the exclusive Obsidian Rush interior that features power massaging front seats and full-grain leather-wrapped seats throughout as well as authentic Vanta Ash wood décor and 12-speaker Bose® Premium Series audio system with Centerpoint surround technology. The AEV Edition also features the AEV logo on the front-seat head restraints and unique AEV-branded floor liners.

The centerpiece of the new cabin is an all-new, tablet-style 13.4-inch-diagonal infotainment3 touchscreen. It is complemented by a 12.3-inch-diagonal configurable driver information center and a 15-inch-diagonal head-up display. Together, they provide customers incredible levels of personalization and intuitive engagement.

Coming in Q3 2023

The 2024 GMC Sierra HD AT4X and AT4X AEV Edition are expected to arrive at dealerships in the fall of 2023. Pricing will be announced closer to the start of production.

Chevrolet Trucks: Building America for 95 years

It started with a simple idea – a few car chassis fitted with hand-built beds to help carry materials around a booming car factory. Before long, millions of Chevrolet pickups were woven into the fabric of a fast-growing country. Chevy trucks tackled the toughest jobs on farms and in the fields, hauled tools and lumber to the burgeoning suburbs and carried families and friends into the wilds for well-earned vacations.

'The legacy that Chevrolet trucks have built over the last 95 years is important to protect,' said Don Johnson, Chevrolet vice president of Sales and Service. 'The best way for us to do that is by delivering the capability and technology our customers have grown to expect, in both our current trucks and in our next generation of full-size pickups.'

Here are some Chevy truck highlights:

1918 Chevrolet Four-Ninety Half-Ton Light Delivery 'Cowl Chassis'

Although there are indications that some Four-Ninety based trucks were built for internal use in 1916, and that a few even earlier chassis may have been converted to ambulances and sent to France in 1914, the first customer chassis appears to have been built in Flint, Mich., on Nov. 22, 1916, and shipped from the factory on Dec. 2 that year.

Two four-cylinder models marked Chevrolet's formal entry into the truck market for the 1918 model year. Both were cowl chassis units that came from the factory with only frontal sheet metal. It was customary at the time for buyers to obtain a wooden cab and cargo box or panel van body to suit their purposes.

Priced at $595, the half-ton Light Delivery cowl chassis was essentially a bodyless Chevrolet Four Ninety car equipped with stronger rear springs. Mounted with a pickup box or panel body, it provided an agile and economical light-delivery truck for small businesses popping up across America in the boom following the First World War.

The second model, a 1-ton capacity 1918 Chevrolet 'Model T' (presumably for 'Truck') cost $1,125 without a body. It was based on the FA-series car, and was built on a truck frame that was longer and stronger than the half-ton model. A 37-horsepower engine gave the larger truck the power to haul heavier loads at a governor-limited top speed of 25 mph.

1930 Chevrolet Pickup

The simple cowl chassis models were replaced in the 1930s by factory-built pickups, which initially came with roadster and closed bodies. Chevrolet bought the Martin-Parry body company in 1930 and quickly began selling steel-body half-ton pickups complete with a factory-installed bed.

At the heart of these new pickups was a new Chevy inline six-cylinder engine, which soon earned names like 'Cast Iron Wonder' and 'Stovebolt' for its rugged design. First produced in late 1928, the new engine had a modern overhead-valve design. Inline six-cylinder engines became a mainstay in Chevrolet cars and trucks for decades to come.

By the mid-1930s, half-ton pickups with factory-installed steel boxes had become the lifeblood of the truck market, with brands like Mack, Studebaker, Reo, and International competing with Chevy, GMC, Ford and Dodge.

1937 Chevrolet Half-Ton Pickup

In the mid-1930s, as the U.S. economy began to recover from the Great Depression, Chevrolet pushed for leadership in a reviving truck market with what were designed to be some of the strongest, most innovative models produced to that point.

For 1937, Chevrolet introduced new trucks with streamlined styling that many still consider the best designs of the era. The '37 also featured a sturdier body and a larger and more powerful 78-horsepower engine, among other improvements.

A 1937 Chevrolet half-ton pickup was sent on a 10,245-mile drive around the United States that was monitored by the American Automobile Association (AAA). Carrying a 1,060 lb. load, the truck averaged 20.74 miles per gallon.

1947 Chevrolet Advance-Design Half-Ton Pickup

In early 1947, Chevrolet introduced its Advance-Design trucks, the first completely redesigned GM vehicles to appear following World War II. Owners of earlier pickup models had asked for a roomier, more comfortable cab with improved visibility and a wider pickup box. They got all of that and more.

Designers sought to make the truck's styling clean, brisk and attractive. Headlamps were now set wide apart in the front fenders and five horizontal bars made up the grille. The design was produced with few major changes from 1947 through 1953, and was then continued with a new frontal appearance into early 1955.

During the Advance-Design trucks' run, there was a measurable shift among Chevrolet customers to trucks. Prior to World War II, the production ratio of the brand's cars to trucks had been about 4:1. By 1950 – the year Chevrolet became the first brand to sell more than 2 million vehicles in a single year – the ratio of cars to trucks was closer to 2.5:1.

1955 Chevrolet Task Force Pickup

By the mid-1950s, the post-World-War II boom was under way, and customers were looking for style and performance even in pickup trucks. In mid-1955, Chevrolet introduced the all-new Task Force trucks, which shared design language with the 1955 Bel Air, and also offered the new small-block Chevy V8 as an option.

Also new to the 1955 truck line was the Cameo Carrier, a high-styled gentleman's pickup more at home in a trendy suburban California bungalow driveway than on a farm or in a factory yard. The Cameo Carrier was only produced through 1958, but it set the stage for new generations of well-equipped personal use pickups, including the El Camino, Avalanche, and Silverado crew cab.

A major engineering advance with tremendous future implications was announced for 1957, when a factory-installed 4-wheel-drive system became available for the first time on select models.

Chevrolet continued to offer the Task Force trucks with annual updates through 1959. During 1958, a new slab-sided Fleetside box option provided an alternative to Chevrolet's traditional step-side pickup box.

1959 Chevrolet El Camino

The original El Camino introduced for 1959 combined the dramatically finned styling of that period's Chevrolet cars with half-ton pickup utility. But the excitement was short-lived. After 1960, the El Camino went on a three-year hiatus.

Chevrolet revived the El Camino 'personal pickup' concept for 1964, with a new version based on that year's new mid-size Chevrolet Chevelle. During the 'muscle car' era that followed, El Camino buyers could order their truck with a Chevrolet high-performance big-block V-8 powertrain, creating a sport pickup that could 'haul' in more ways than one. By 1968, a complete Super Sport package was available.

The Chevelle El Camino enjoyed a devoted following and was produced through two more styling generations (1968-1972 and 1973-1977). For 1978, the El Camino was successfully transitioned to that year's new, smaller Malibu platform. The final El Caminos were 1987 models.

1961 Corvair Pickup

Although there had been a number of small pickups prior to the 1960s, the compact car boom that kicked off the decade brought with it a new crop of forward control trucks, including the Corvair 95. With its unitized body structure and rear-mounted engine, the 95 offered a lot of cargo space in a compact maneuverable package. The Rampside model offered a side gate on the right side of the vehicle, which allowed easy access to the low load floor at the front of the bed. Although clever in design, the Corvair 95 never caught on in the showroom, and in the final model year of 1964, only 851 were sold.

1967 Chevrolet C-10 with Custom Sport Truck Package

It took only one glance at any of the 35 Chevrolet C/K models for 1967 to see that Chevy trucks had a new look that year. The exterior profile, which would characterize Chevrolet C/K models through 1972, featured a lower-silhouette cab and large, rounded wheel openings. The new chassis had coil springs front and rear.

A new-for-1967 Custom Sport Truck package was a trend-setting option that included deluxe, car-like upgrades inside and out. The package could even be ordered in combination with bucket seats.

By 1967, the Federal Interstate Highway System was giving Americans unprecedented access to the nation's natural wonders and recreational areas. Customers who enjoyed such pursuits appreciated the small-block and big-block V-8 power choices that gave Chevrolet trucks the torque needed to pull trailers up grades, and horsepower to cruise comfortably with a camper at Interstate speeds.

1972 Chevy LUV

In spring of 1972, Chevrolet started selling the LUV pickup on costal markets. Built by GM partner Isuzu, the LUV featured a 75-horsepower four-cylinder engine and four-speed manual transmission. Although the specs were modest, the LUV was a fully functioning pickup, with a ladder-style frame, a six-foot bed, and a payload of 1,100 pounds, plus room for two passengers. Within a few years, soaring gas prices would make compact pickups like the Chevy LUV a major factor in the U.S. truck market, and it wasn't long before Chevrolet started work on a home-grown small truck.

1982 Chevrolet S-10

The Chevrolet S-10 was the first domestically produced compact pickup, larger than the imported Chevy LUV but smaller than the full size C/K model. An 82-horsepower four-cylinder engine was standard, with an available 110-horsepower V6 – the only one in the class. Properly equipped, the S-10 could haul 1,500 pounds, and tow 4,000. The roomy cab and high levels of standard and optional equipment gave the S-10 a broader appeal than that of earlier, bare-bones small trucks, and it quickly became a mainstay of the Chevrolet lineup, appealing to everyone from young customers looking for a first set of wheels to businesses seeking a rugged work truck.

1988 Chevrolet Pickups

Pickup trucks had been slowly migrating from the worksite to the suburbs, and the 1988 Chevrolet C/K pickup accelerated that trend, bringing the aerodynamics, electronics and materials that had revolutionized the automobile over the past decade to the full-size pickup. Extensively tested to make sure it met the high bar for dependability set by previous Chevy pickups, the new truck also featured advanced aerodynamics for improved fuel economy, including a narrower cab for lower drag, flush side glass, and a sleek front end with integrated lamps.

A full range of powertrains was offered, from a 4.3-liter V6 through a 6.2-liter diesel V8. To enhance durability, the trucks featured extensive use of galvanized steel for corrosion resistance, and a full welded frame with a boxed front section for strength and rigidity. Civilized driving characteristics and styling moved full-size pickups closer to being the family vehicles they are today.

1999 Chevrolet Silverado

Chevrolet's all-new 1999 full-size pickups were the first to carry the Silverado nameplate. The new trucks resulted from the most intensive development program yet undertaken by General Motors and they arrived just in time for a boom in truck sales. The styling of the new Silverado pickups built on the purposeful design that characterized the preceding C/K pickups. Interiors had all the comfort and convenience features personal-use customers were starting to expect. Power came from a new generation of V8 engines.

2004 Silverado 1500 Crew Cab

The 2002 Chevrolet Avalanche pioneered the idea of a light-duty pickup that could comfortably accommodate the family, and the 2004 Silverado took this idea and ran with it. In less than eight years, light-duty crew cabs would dominate the full-size pickup market, accounting for more than two-thirds of all sales, and transforming pickups into a true multi-purpose vehicle for both work and family. Available creature comforts included dual-zone climate control, Bose sound systems, a rear-seat DVD player, OnStar and XM radio. Even with the creature comforts, Silverado maintained the Chevy truck capability.

2007 Silverado

The all-new 2007 Silverado provided significant improvements in performance and fuel economy, while strengthening the capability and dependability Chevy pickups were known for. It featured a new fully boxed frame, coil-over-shock front suspension, and rack-and-pinion steering for improved ride and handling, while new Gen IV small-block 5.3L and 6.0L V-8 engines could deactivate four of the eight cylinders when not needed to save fuel. Safety advances included StabiliTrak electronic stability control and head-curtain side airbags for enhanced occupant protection.

2013 Chevrolet Colorado

Just as full-size pickups have become the lifeblood of the American economy, midsize pickups are important vehicles for businesses and families in many countries outside the United States. Chevrolet's new global mid-size Colorado pickup is designed to help expand the Chevrolet brand into many of the world's fastest-growing markets.

Developed under the direction of a truck-savvy team from GM do Brasil, the inaugural version of the global Colorado was launched in Thailand, the world's largest market for midsize pickups, in November, 2011. Over the next several years, Colorado will be introduced into many global markets, including the United States, where it will offer a more fuel efficient alternative for customers who don't need all of the capability of a full-size pickup.
