• Higher trailering capability and confidence are driven by new hardware and technologies DETROIT — Bigger, stronger and smarter, the all-new 2020 GMC Sierra Heavy Duty combines greater trailering capability with technologies designed to provide customers with a world-class towing experience.
'The all-new 2020 Sierra HD is the most capable heavy-duty truck that we've ever offered,' said Duncan Aldred, vice president of Global GMC. 'For customers who demand a premium, innovative heavy-duty truck that supports their passions, the next-generation Sierra HD can pull like a pro.'
Form and function come together in the new Sierra Heavy Duty, with features that include: •An enhanced ProGrade Trailering system featuring class-leading available 15 camera views, including a segment-first transparent trailer view to virtually see through a trailer in tow.1 •An available smart trailer designed to integrate the iN∙Command® control system from ASA Electronics2provides the ability to monitor and control select functions of compatibly equipped trailers through the myGMC mobile app3. •A segment-exclusive available 15-inch-diagonal head-up display that offers useful trailering information, including vehicle speed, navigation information and an inclinometer display for the road grade. •An available segment-first Rear Camera Mirror. •MultiPro, the world's first six-function tailgate, allows easier loading, unloading and bed access and is available on all trim levels. •A larger, commanding design that provides more room for cargo and occupants. •Best-in-class Crew Cab front headroom and legroom for the driver and other front-row occupants. •An all-new, segment-first, Allison 10-speed automatic transmission mated to the legendary 6.6L Duramax turbo diesel. •For those looking to take refined capability off-road, GMC fortifies the new AT4 brand with an all-new Sierra AT4 Heavy Duty available for Crew Cab configurations as both a 2500 and 3500 single rear wheel offering.
With more than half of Sierra HD customers choosing Denali, it continues to offer the ultimate expression of professional grade materials and refinement. The all-new model delivers power, intelligence and segment advancements to meet the needs of heavy-duty customers with discerning taste. ProGrade Trailering Technology First introduced with the 2019 Sierra light duty, the ProGrade Trailering System leverages technology advancements to offer additional features and functionality for the 2020 Sierra Heavy Duty.
'Trailering is the most important consideration for Sierra Heavy Duty customers, and the new features and technologies in the 2020 Sierra HD make it easier than ever to hitch a trailer and tow it confidently,' said Jaclyn McQuaid, vehicle chief engineer, Heavy Duty Trucks. 'We've developed this new truck to offer the greatest trailering experience ever offered by GMC.'
An available class-leading 15 unique camera views1, including an industry-first transparent trailer view, help optimize the driver's view around the truck and compatible trailers to provide added confidence when towing. The revolutionary transparent trailer feature uses the tailgate-mounted camera and an available accessory camera mounted on the rear of the trailer. The resulting display helps the driver to virtually see through the trailer4, a benefit when navigating parking lots, merging into traffic or making tight turns.
Owners of the 2020 Sierra HD will have access to available smart trailer technology designed to allow access to select features of the iN∙Command® control system from ASA Electronics2 through the myGMC mobile app, either on compatible Android and iOS smartphones or on the vehicle's infotainment system via Apple CarPlay5 or Android Auto6. Similar to the features of a smart home, the iN∙Command® control system acts as the central hub of operations to monitor and control an array of systems in trailers equipped with the next-generation technology. Depending on how a compatibly equipped trailer is configured, owners of the 2020 Sierra HD may be able to turn on the trailer's air conditioning or water heater, check water and holding tank levels, or monitor fuel levels on trailers equipped with generators — all before arriving at their destination.
The ProGrade Trailering System also includes an in-vehicle Trailering App7 with Trailer Light Test, Trailer Electrical Diagnostics, Trailer Tire Pressure and Temperature Monitoring, Pre- Maintenance Reminders and Departure Checklist. Many of the Trailering app's functions, including the lighting test and pre-departure checklist, are also available with the myGMC mobile app, a feature that offers great convenience when outside the truck or trailer.
Additional available technologies and hardware to aid trailering include: •Auto Electric Park Brake to automatically apply the parking brake to help maintain truck position when hitching. •All-new Park Grade Hold Assist enhances hill hold by using braking effort at each wheel for an extended period of time. •All-new larger, door-mounted trailering mirrors with a four-bar link providing power extend and retract for the driver and passenger sides. •Integrated trailer brake controller that works with the trailer profile in the Trailering App to recall a specified trailer's most recent gain setting. •Tow/Haul mode that remains engaged on the next key-on cycle, for up to four hours; includes a reminder the feature is engaged. •Hill Start Assist and Hill Descent Control. •Trailer Sway Control. •Auto Grade Braking and Diesel Exhaust Braking. •Digital Variable Steering Assist that dynamically optimizes power steering according to driving scenarios, including trailering, and enables features like road pull compensation. •Trailering Info Labelplaced on the driver's door jambthat clearly calls out the truck's specific trailering information, including curb weight, GVWR, GCWR, maximum payload, maximum tongue weight and rear GAWR.8 Bigger and bolder The 2020 Sierra HD has a commanding, powerful design rooted in a new architecture with larger proportions. It is taller and longer, with a more confident stance defined by a bold design that epitomizes GMC's signature refinement and technologically driven attention to detail.
'We took every opportunity to visually express the strength and capability that lies beneath the surface,' says Matt Noone, director of GMC exterior design. 'The elevated hood line, the strong shoulders, the striking front grille — these cues communicate the strength and performance that have been engineered and built into each and every Sierra Heavy Duty.'
The all-new Sierra HD is highlighted by new signature lighting, including prominent 'light blades' that deliver LED illumination for the daytime running lamps. LEDs are also used for the headlamps, taillamps, available fog lamps and other illuminative elements, including the available roof marker lights standard on all dual-rear-wheel HDs and all Sierra HD Denalis except where prohibited by law.
Inside, the Sierra HD's new interior has best-in-class front head- and legroom (maximum), with Crew Cab models. A higher seating position complements the truck's taller profile to offer a confident view from behind the wheel. Additional optimized ergonomics emphasize easy, intuitive interaction with the vehicle's available technologies, such as a heavy-duty segment-first head-up display and GMC's latest touchscreen infotainment systems.9
Denali-exclusive materials — including premium leather-appointed seating, authentic open-pore wood trim and dark-finish aluminum decor — raise the interior's refinement. The leather appointments have a distinctive, large-pebbled grain with a contrasting stitch pattern that is premium in appearance and touch without sacrificing durability, and the wood trim features an open-pore texture evocative of hand-planed furniture. Compared to the current model, the new Sierra Heavy Duty has: •A longer wheelbase, a taller, more dominant hood line and taller overall height. •A larger grille and complementing functional hood scoop to feed an advanced cooling system for the Duramax turbo diesel. •Class-leading heavy-duty cargo bed volume10 and 12 corner tie-downs with a new, available 120-volt power outlet. •One-inch-lower bed lift-in height compared to the 2019 Sierra Heavy Duty, providing easier loading and fifth-wheel and gooseneck trailer hitching10. •New, segment-exclusive cargo bed side steps on all box styles, located in front of the rear wheel openings, that complement integrated CornerSteps in the rear bumper to improve access to the cargo area. •World's first six-function MultiPro tailgate available on all trim levels and standard on SLT, AT4 and Denali. All-new Sierra AT4 HD: Refined HD Capability Off-Road The all-new 2020 Sierra Heavy Duty AT4 continues the AT4 brand's growth with a distinctive off-road identity to complement its robust HD capability. Driven by dark chrome exterior finishes and contemporary detailing, Sierra HD AT4 features front and rear bumpers and a grille surround finished in body color. The bold grille design, with its rugged texture, is finished in black chrome and set off by the AT4's distinctive red vertical recovery hooks.
The athletic interior also carries AT4-specific darkened trim, including dark-tinted and textured aluminum finishes on the steering wheel, center stack and sill plates, as well as a unique Jet Black interior with Kalahari color accents in the seats and live stitching. Leather-appointed seating, with mini-perforated inserts and embroidered AT4 badging on the headrests, along with all-weather floor liners, is standard delivering durability with uncompromising comfort.
The new Sierra AT4 Heavy Duty's off-road capabilities are rooted in a unique suspension and supporting technologies that include: •Off-road suspension, Rancho Shocks, skid plates, Eaton locking rear differential. •Eighteen-inch wheels wrapped with Michelin all-terrain tires, with 20-inch wheels available. •Traction Select System with specific Off-Road mode. •Hill Descent Control and Hill Start Assist. •Segment-exclusive 15-inch diagonal Head-Úp Display with Off-Road Inclinometer. •HD Surround Vision1 for low-speed views of vehicle surroundings. Confident trailering power GMC's legendary Duramax turbo diesel and Allison Transmission pairing continues to offer the ultimate in towing confidence.
The proven Duramax 6.6L turbo-diesel engine offers high torque, high power, low noise and exceptional durability. For the 2020 Sierra HD, the Duramax offers an SAE-certified 445 horsepower and 910 lb-ft of torque. This already powerful engine performs more efficiently thanks to increased cooling capacity delivered in part by improved air induction. A dual-path intake system draws dense, cool air through both the prominent hood scoop and the larger front grille.
The new Sierra HD marks the introduction of an all-new 10-speed Allison automatic transmission — the first-ever offered in the heavy-duty pickup segment. The all-new 10-speed transmission with closer gear spacing allows the engine to operate in an optimal range at all times with varying load and terrain conditions.
The bigger frame, stronger propulsion and smarter technologies are expected to deliver dramatically greater towing capacity than previous models, well in excess of 30,000 pounds. More details regarding an all-new gas engine and trailering capabilities will be announced shortly. Coming late summer 2019 The 2020 Sierra HD goes on sale later this year in 2500HD and 3500HD dual rear wheel and single rear wheel configurations. Pricing and complete specifications will be announced later.
With a $1.5 billion investment to support the next-generation Heavy Duty truck launch, Flint Assembly in Flint, Michigan, will proudly build the 2020 Sierra Heavy Duty.

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 Ú.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 Únited 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 LÚV
In spring of 1972, Chevrolet started selling the LÚV pickup on costal markets. Built by GM partner Isuzu, the LÚV featured a 75-horsepower four-cylinder engine and four-speed manual transmission. (posted on conceptcarz.com) Although the specs were modest, the LÚV 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 LÚV a major factor in the Ú.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 LÚV 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.
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. (concept carz) 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 Únited 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 Únited 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.Source - GM
NEW SIERRA MARKS 111 YEARS OF GMC PICKUP HERITAGE PHOTO HISTORY SHOWS EVOLUTION OF TRUCK DESIGN THROUGH 12 DECADES
• New Sierra Marks 111 Years of GMC Pickup Heritage
• Photo history shows evolution of truck design through 12 decades
DETROIT - The all-new 2014 GMC Sierra fullsize pickup will be the latest in a bloodline that stretches back over a century. The first truck to wear a GMC badge debuted in 1912, while a predecessor from the Max Grabowsky's Rapid Motor Vehicle Co. was the first commercial truck operated in the City of Detroit 10 years earlier.
Here's a list of highlights by decade, accompanied by a corresponding photo of each. • 1900s: The first Rapid truck - little more than a seat, an engine cover and a frame - was delivered in 1902. • 1910s: The GMC name takes its place on a truck grille for the first time in 1912 and the mix of trucks offered had either upright front ends or curved 'French' fronts. • 1920s: 1927 was a milestone for design features with more stylized fenders, headlights attached to the radiator, and the first chrome-plated radiator surround. • 1930s: Streamlining in the '30s added sloped grilles, more paint color options and passenger cabs inspired by car design trends, which helped expand the truck market. • 1940s: Following the war, GMCs of the late '40s featured fully integrated headlights for the first time, as well as wider, lower, and bolder grilles. • 1950s: Cars again influenced truck design in the '50s, resulting in more safety, comfort and performance. 1955 highlights were hooded headlights and panoramic glass. • 1960s: The first GMC pickup with a full-width hood debuted in 1960. Other design cues included 'jet pod' grilles at the front and a pinched-waist body crease on each side. - 1970s: Padded materials replaced many metal interior surfaces in the '70s. Heavy duty models offered a dual rear axle for the first time and the Crew Cab debuted. - 1980s: In 1987, the Sierra name became standard for all full-size pickups with the introduction of a new, more aerodynamic generation of GMC trucks. - 1990s: The '90s brought the first rear-hinged three-door Extended Cab model. In 1999, new generation of truck introduced the first use of frame hydroforming. - 2000s: The new millennium brought the 'D' decade: The first Duramax diesel engine for Sierra HD added capability and the first Denali pickup set a luxury standard for trucks. - 2012: The new 2014 Sierra debuts on December 13.
GMC has manufactured trucks since 1902, and is one of the industry's healthiest brands. Innovation and engineering excellence is built into all GMC vehicles and the brand is evolving to offer more fuel-efficient trucks and crossovers, including the Terrain small SÚV and Acadia crossover. GMC is the only manufacturer to offer three full-size hybrid trucks with the Yukon, Yukon Denali SÚVs and the Sierra pickup. The Sierra Heavy Duty pickups are the most capable and powerful trucks in the market.
