2008 GMC SIERRA HEAVY-DUTY TRUCKS: READY FOR ANY TASK
GMC Sierra introduced all-new heavy-duty pickups during the '07 model year. They were highlighted by all-new and differentiated exterior designs, two unique interiors and class-leading power and efficiency. They roll into 2008 ready for work or leisure, wîth minor refinements and enhancements, while still loaded wîth §egmènt-leading and §egmènt-exclusive features.
Sierra heavy-duties are offered in a range of 2500HD (three-quarter-ton) and 3500HD (one-ton) models and are available in WT, SLE and SLT trim. The range of configurations – three cab styles, three cargo box styles and five wheelbase lengths – delivers tremendous choice. Some full-size truck manufacturers do not even offer three-quarter-ton or one-ton heavy-duty trucks. And among those that do, the 2008 Sierra HD pickups offer many §egmènt-best capabilities, including 18,500-pound (8,392 kg) gross combined vehicle weight rating for vehicles wîth a gas V-8 and a 13,000-pound (5,897 kg) conventional trailer weight rating enabled by a larger-capacity trailer hitch platform. Maximum towing capacity is 16,700 pounds (7,575 kg), when equipped wîth a fifth-wheel hitch.
Changes to the Sierra 2500HD and 3500HD for '08 are minor and include standard XM Satellite Radio on all models, availability of a power-adjustable driver's seat on regular cab models wîth a bench seat and two new exterior colors: Dark Crimson Metallic and Sonoma Red Metallic.
Dually models in 2008 receive new, larger 17-inch wheels (replacing 16-inch wheels), which are available wîth bright wheel covers. Bold and distinctive exterior designs
Sierra HD models have a distinctive front end wîth a prominent GMC emblem set in a large, chrome-ringed grille (black grille surround on Work Truck models). The grille is flanked by large, jeweled-appearance headlamps. SLT models feature large foglamps set into the bumper, creating an upscale appearance that further reflects GMC's brand identity.
The trucks are refined lòòking, too, wîth doors that extend over the rockers for a smooth, uninterrupted look, and lamps that have a jeweled appearance. The door handles feature large, grab-style designs that are easy to open wîth gloves. Tolerances between panels are minimal – including a 50-percent reduction in the space between the cab and cargo box – which enhances the overall sleekness of the design. Cab and cargo box configurations
Sierra 2500HD and 3500HD are offered in regular, extended and crew cab configurations, which are complemented wîth standard (6-foot 6-inch) and long (8-foot) cargo box lengths. Sierra 3500HD models also are available wîth the Dually dual rear wheel configuration on a long (8-foot) box. Features such as 170-degree-opening (164 degrees wîth dual rear wheels) rear access doors wîth fully retractable power windows on extended cab models, offer increased versatility.
The pickup boxes have great versatility, strength and capacity. A one-piece wheelhouse and inner box side offers strength and a smoother, more integrated appearance. The boxes are 1.18 inches (30 mm) deeper in the front and 1.57 inches (40 mm) deeper at the rear than previous-generation models, wîth stronger inner walls that offer improved performance when fitted wîth ladder racks, toolboxes and other accessories. Cargo bed volume is 60.7 cubic feet (1,718 L) wîth the regular box and 75.5 cubic feet (2,138 L) wîth the long box.
Dually cargo boxes are completely made of steel, including hydroformed sheet metal outer fenders. They have a smooth, integrated appearance and enhanced strength. All Dually models feature marker lights on the fenders and new, sleek cab roof lights that are aerodynamically integrated into the top of the cab.
The tailgate designs include a lock and an available EZ Lift feature, wîth torque-rod assist. The tailgates are also easily removed by simply opening to 45 degrees and pulling straight out and away from the vehicle.
An innovative cargo management system is available and is complemented by a range of dealer-ordered accessory packages. Three rails that run the length of the box sides and the forward box wall are secured wîth high-strength anchors and, unlike competitors' systems, incorporate upper and lower tracks. Four adjustable tie-down brackets are included wîth each system and can be located anywhere on the tracks, each rated for a load point of 500 pounds (227 kg).
At the heart of a comprehensive accessories portfolio for the pickups is a group of specific accessory products designed to integrate into the cargo management system. The rails enable the use of an overhead utility rack rated at 500 pounds (227 kg) loading capacity, a sliding diamond plate toolbox, a sliding bed divider and diamond plate side storage boxes. These accessories use either the upper or lower rails, allowing numerous combinations that can easily fit together or bypass one another as they slide along the rails. The toolboxes use a codeable lock, enabling the vehicle key to be used for locking and unlocking these accessories. Segment-leading interior designs wîth superior craftsmanship
GMC Sierra 2500HD and 3500HD are quieter, more spacious and refined inside, wîth increased passenger comfort and storage space. Each features two distinct interior designs that reflect their respective brand identities, including specific trim, appointments and gauge cluster appearance.
Base- and midlevel-trim models include a functional pure pickup interior design theme wîth a contemporary adaptation of GM's ergonomic cockpit instrument panel design. In addition, this interior includes specific door panels wîth large door pull and release handles, as well as unique seat configurations; center console and underseat storage systems. It also includes two glove boxes (a traditional lower glove box and a covered upper storage compartment).
Luxury-inspired premium interiors are standard on SLT models. They offer richly appointed features, including a distinct instrument panel design, large-capacity center console (20.1 L), specific door panels, seats and other trim elements. Features on the premium interiors include power-adjustable heated bucket seats, leather-surface seats, leather-appointed §teering wheel and selective chrome trim.
Spaciousness in each interior trim level is enhanced wîth 'low and forward' instrument panels that provide a more airy feel to the cabin as well as a panoramic field of vision. The instrument panels are mounted approximately 3.5 inches (90 mm) down and forward on the pure pickup interiors, while the premium interior instrument panel is located 5 inches (127 mm) down and forward. Both instrument panel designs are integrated into their specific door panels to create a swept appearance.
All interiors are refined and craftsmanship is highlighted by flush surfaces, tight gaps and tolerances on the instrument panel, center stack, clusters and other components. Most gaps on the instrument panels and clusters are 0.5 mm or less. Attention to detail was given to concealing fasteners and metal structural components of all seats. There is no exposed hardware in the interior or doorsills. Soft-touch and low-gloss finishes for the instrument panels and other trim pieces are used throughout. The color and grain of the materials were carefully selected to provide a premium look.
Complementing the interiors' finely crafted look and feel is exceptional quietness. All trim levels – even base work truck models – benefit from a comprehensive system that delivers a passenger environment almost devoid of noise. This is achieved wîth the use of strategically placed sound-deadening and sound-absorbing material in the body structure – including liquid-applied dampener on the floor and front-of-dash – as well as the inherent, vibration-minimizing traits of the stiffer frame and quieter attributes of the aerodynamically tuned exterior. Also, improved-design door sealing and a doors-over-rockers design help eliminate road and wind noise.
Additional highlights of GMC Sierra heavy-duty interiors include:
• A stadium-style rear seat wîth a 60/40-split design and folding center armrest can be easily folded up to provide an uninterrupted load floor. Or, either section of the split seat can be stowed independently, allowing room for both cargo and a rear-seat passenger
• A 'double' glove box, which includes a large-capacity, traditional glove box and a new, covered storage compartment above it, wîth a 3.4-liter storage capacity
• Models equipped wîth the luxury-inspired premium interior come wîth a single large glove box for substantial storage capacity
• The premium interiors include large center consoles wîth the §egmènt's largest storage capacity: 20.1 liters of undivided volume
• The pure pickup interiors feature a 6.1-liter armrest storage console and an underseat storage bin built into a new 40/20/40-split bench seat. This 9.1-liter lockable storage bin, which includes an accessory power outlet, is located under the center seat cushion and is large enough to store a laptop computer
• The gauges have an analog display, wîth large, easy-to-read graphics. They are lit wîth ice-blue LED lighting, which provides crisp, bright illumination and a more upscale look. A driver information center is incorporated on the instrument panel
• Air conditioning is standard on all models, wîth a dual-zone automatic system available on some models. The dual-zone system allows for up to a 30-degree F difference in temperature settings between the driver and front passengers
• Power-operated rear side glass is featured on extended cab models. The windows lower completely into the rear access doors
• Power-operated back glass is available on extended and crew cab models. The window operates wîth the touch of a button located on the overhead console.
• A large, power-operated sunroof is available on extended and crew cab models. The crew cab sunroof has a tilt/slide design, wîth a sliding sun shade and express open/close feature. The extended cab sunroof uses a spoiler-type sunroof design that slides back over the roof surface
• Últrasonic Rear Parking Assist provides audible warnings of objects behind the vehicle
• A heated windshield washer fluid system more effectively removes bug spatter and thin layers of ice and frost. When the system is activated, washer fluid is heated to 150 degrees F (60 C) or more
• A diverse range of radio systems – including single-CD, six-disc CD, MP3- and DVD-capable – is available. Several radios feature RDS technology, which provides enhanced information for participating FM stations
• A rear-seat entertainment system isavailable on crew cab models; it combines a dual-play radio system, rear-seat audio controls and a larger, eight-inch flip-down screen
• Two touch-screen DVD-based navigation radio systems are offered; one is specific for systems equipped wîth the rear-seat entertainment system
• OnStar wîth Turn-by-Turn Navigation.
The standard engine is a 6.0L gas V-8 wîth variable valve timing. It is rated at a best-in-class 353 horsepower (263 kW) and 373 lb.-ft. of torque (506 Nm)* on single rear-wheel configurations (up to 10,000 pounds gross vehicle weight rating). Variable valve timing helps improve performance and fuel economy.
A Hydra-Matic 6L90 six-speed automatic transmission is paired wîth the engine. This powertrain combination offers a higher maximum gross combined weight rating (GCWR) – 18,500 pounds (8,392 kg) – than previous gas-powered combinations and is the §egmènt leader for vehicles wîth a V-8 gas engine. The 6L90 has a wide, 6.04:1 overall ratio – including two overdrive gears – that helps deliver an excellent balance of performance and fuel economy. It also offers manual range selection and tap up/tap down control.
A cleaner, more powerful Duramax 6.6L turbo-diesel engine is available. It continues to lead the §egmènt in power and torque, wîth power ratings of 365 horsepower (272 kW) and 660 lb.-ft. of torque (895 Nm). Úpgrades to the engine introduced in '07 include a diesel particulate filter system that helps provide a 90-percent reduction in particulate matter and a 50-percent reduction in NOx (compared wîth pre-2007 standards), meeting a new federal government mandate that went into effect on Jan. 1, 2007.
The renowned Allison 1000 six-speed automatic transmission is partnered wîth the Duramax 6.6L turbo-diesel engine. It delivers good fuel economy, quietness and control. It features a class-first range selection function, which allows the driver to easily select the desired gears to match driving conditions, such as towing a trailer on a steep grade.

Working in concert wîth the powertrains are a strong chassis and responsive suspension systems. The vehicle frame is comprised of a sturdy ladder design that is reinforced wîth cross braces. It features a §egmènted design that enables easy and accurate adaptation of numerous lengths to accommodate the trucks' five wheelbase lengths. The frame sections are joined wîth strong, overlapping §egmènts that bolster overall strength and rigidity.
The strength of the frame and enhanced capabilities enabled by the powertrain systems allow the Sierra heavy-duty trucks to offer a larger, 2.5-inch trailer hitch receiver platform. This enables the trucks to pull a §egmènt-leading maximum of 13,000 pounds (5,897 kg) wîth conventional trailers. Trucks wîth fifth-wheel hitches can tow up to 16,700 pounds (7,575 kg), when properly equipped.
• All 2500HD and 3500HD models ride on a wide, 68.6-inch (1,742 mm) front track. The rear track on 2500HD trucks is 66 inches (1,676 mm); the rear track on 3500HD models is 74.7 inches (1,897 mm), giving Sierra heavy-duty models a firmly planted feel.
• Two suspension packages: Z85 and Z71. The Z85 suspension is standard on 2WD and 4WD models; the Z71 Off Road suspension is optional and includes additional chassis and suspension equipment, including skid plates.
• A recirculating ball §teering system delivers a confident feeling of control and on-center feel.
• A high capacity, four-wheel disc brake system wîth Hydroboost and four-wheel ABS is standard on all models. The brake system includes large-diameter front and rear disc rotors and stiff brake calipers.
All heavy-duty models are available wîth an integrated trailer brake controller. It is integrated wîth the ABS system and provides immediate and measured brake force signaling to electric-controlled trailer brake systems. There is no requirement for external and/or aftermarket brake control systems. The brake controller switch is conveniently mounted on the lower-left section of the instrument panel. Safety details
Sierra heavy-duty models are designed to help drivers avoid crashes and protect passengers in the event one occurs. The robust ladder frame and strong body structure provide occupant protection. The frame is designed wîth crush zones that crumple to absorb crash energy, while the body structure incorporates the strategic use of high-strength steel and structural adhesives designed to help maintain passenger compartment integrity and manage energy in a crash.
Additional safety features include:
• Frontal air bags are standard on all models
• Segment-first front safety belt pretensioners wîth both front and rear crash sensing
• A standard, high capacity four-wheel disc brake system wîth four-channel ABS system provides superior stopping capability

Chevrolet Trucks: Building America for 95 years
It started wîth a simple idea – a few car chassis fitted wîth 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 wîth 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 wîth stronger rear springs. Mounted wîth 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 wîth roadster and closed bodies. Chevrolet bought the Martin-Parry body company in 1930 and quickly began selling steel-body half-ton pickups complete wîth 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 wîth factory-installed steel boxes had become the lifeblood of the truck market, wîth brands like Mack, Studebaker, Reo, and International competing wîth 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 wîth what were designed to be some of the strongest, most innovative models produced to that point.
For 1937, Chevrolet introduced new trucks wîth 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 wîth 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 wîth few major changes from 1947 through 1953, and was then continued wîth 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 lòòking for style and performance even in pickup trucks. In mid-1955, Chevrolet introduced the all-new Task Force trucks, which shared design language wîth 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 wîth 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 wîth 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 wîth 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, wîth 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 wîth 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 wîth 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 wîth 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 wîth 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 wîth 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, wîth 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, wîth 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 lòòking 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 wîth 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 wîth 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 wîth 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 wîth 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 §teering 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
