GMC Sierra's broad lineup of body styles, powertrains and traction systems gives full-size truck customers almost limitless choices to tackle any job or recreational interest – and do it wîth Professional Grade confidence.

For the 2006 model year, Sierra's versatility expands wîth new models, including an Extended Cab wîth short-length cargo box (available wîth 2WD or 4WD) and new base-model 1500 SL Crew Cab models (2WD and 4WD) that carry a lower MSRP than previous Crew Cab models.

On the performance front, a new VortecMAX Performance Package delivers improved towing; an increase in the 5.3L V-8 engine's gross vehicle weight rating results in improved payload levels on extended and Crew Cab models; and engine upgrades to the Duramax Diesel 6600 result in enhanced horsepower and torque. In addition, the Sierra Heavy-Duty lineup is bolstered wîth the Allison 1000 Series transmission, which grows from a five-speed automatic to a six-speed.

Sierra models are available wîth 2WD, 4WD and, wîth the unique Sierra Denali, full-time all-wheel drive. And because Sierra customers do more than haul construction equipment, the availability of stylish 20-inch chrome wheels expands in '06 on light duty. For heavy duty models, chrome-clad 16-inch wheels are available for the Crew Cab long box/single rear wheel models.

Here's a closer look at all that's new wîth Sierra in 2006:

Sierra 1500 Extended Cab/Short Box models: The Sierra 1500 is now available wîth a new extended cab/short box configuration. Available wîth 2WD or 4WD, the extended cab design is matched wîth a 5-foot 8-inch box – the same as Crew Cab models – giving customers three bed choices: short, standard (6-feet 6-inches) and long (8-feet).

Sierra extended cab/short box models are available wîth SLE or SLT trim and include the Vortec 5300 V-8 (LM7), which is rated at 295 horsepower (220 kw) and 335 lb.-ft. of torque (463 Nm). Two-wheel drive models have a GVWR of 6,200 pounds (2,812 kg); the 4WD model has a 6,400-pound (2903 kg) GVWR. Twenty-inch wheels are available, as are the popular sunroof and manual-sliding rear window features that were introduced in 2005.

Sierra SL Crew Cab model: A new base-model SL Crew Cab model, available in 2WD or 4WD, allows customers to select the useful Crew Cab configuration at a lower MSRP. Compared wîth uplevel Crew Cab models, the new SL offers the Vortec 4800 V-8 as standard equipment. Chrome 17-inch wheels and remote keyless entry are among the standard features.

Crew Cab SL models receive a standard Z85 suspension, along wîth a 3.23 axle for 2WD models and 3.73 rear axle wîth 4WD models – 4WD models come wîth a manual-control transfer case.

VortecMAX Performance Package: The VortecMAX performance package wîth enhanced Heavy Duty towing is designed to increase the towing capability of 4WD models of the Sierra 1500 extended cab/standard-length box and Sierra 1500 Crew Cab. The package includes a high-output Vortec 6000 engine rated at 345 horsepower (257 kw) and 380 lb.-ft. of torque (515 Nm), 17-inch wheels, a heavy-duty trailering package, new 9.5-inch rear axle, automatic locking differential, VortecMAX door badging and engine cover.

The high-output 6.0L engine and heavy-duty 9.5-inch axle help give Sierra improved towing capability. The package enables a 10,000-pound towing capacity on the extended cab model and up to 9,900 pounds wîth the Crew Cab.

Sierra Performance Edition: For SLE/SLT Extended Cab 2WD models, the Sierra Performance Edition pairs the VortecMAX high-output Vortec 6000 powertrain wîth 20-inch chrome wheels, which combine to create a powerful and road-ready Sierra. This package also includes a VortecMax door badge and engine cover, 3.73 rear axle, high performance suspension, HD automatic transmission, HD trailering, HD oil cooler, automatic locking differential, engine oil cooling system and traction control.

GVWR increase: Performance improvements will also be realized on extended and Crew Cab models powered by the 5.3L V-8 engine as a gross vehicle weight rating increase results in improved payload levels.

New diesel engine: An all-new version of the Duramax 6600 turbo-diesel V-8 engine will debut in the interim 2006 model year as an option on Sierra Heavy Duty models. When mated to an all-new Allison 1000 six-speed automatic transmission, the new powerplant will deliver more horsepower – 360 hp (268 kw) at 3200 rpm – and increased torque, at 650 lb.-ft. (881 Nm). The power increase comes wîth lower emissions and significantly improved quietness and smoothness.

The Duramax 6600's horsepower and torque increase and emissions reduction are enabled by a strengthened iron cylinder block and a lower compression ratio. The lower compression reduces stress on the engine by reducing the peak cylinder firing pressure. This, in turn, allows more fuel to be burned – more fuel means more power – while the lower compression helps reduce NOx emissions. Lower compression also helps reduce noise and vibration, making the 6600 a quieter and smoother engine.

A revised variable-geometry turbocharger also enhances the driving experience of the Duramax 6600. Aerodynamic changes to the turbo's impellers help tailor controlled application of turbo power for seamless and immediate response at full throttle. The turbo, which spins at up to 120,000 rpm, is high-speed-balanced, reducing vibration and resonance – and contributing to the engine's overall smoothness and refinement. The revised turbo also helps reduce emissions, while maximum boost remains at 20 psi.

Another new feature of the Duramax 6600's turbo system is the capability of the variable-geometry turbocharger to provide exhaust braking. This function is available on some medium duty truck models and can replace add-on exhaust brake hardware. With the new system, braking is controlled by a signal from the engine controller and can be activated by the driver.

The comprehensive list of changes and upgrades to the 2006 Duramax 6600 includes:

Cylinder block casting and machining changes strengthen the bottom of the cylinder bores to support increased horsepower and torque
Úpgraded main bearing material increases durability
Revised piston design helps lower compression ratio to 16.8:1 from 17.5:1
Piston pin bore diameter increased to for increased strength
Connecting rod 'I' section is thicker for increased strength
Cylinder heads revised to accommodate lower compression and reduced cylinder firing pressure
Maximum injection pressure increased from 23,000 psi to almost 26,000 psi
Fuel delivered via higher-pressure pump, fuel rails, distribution lines and all-new, seven-hole fuel injectors
Fuel injectors spray directly onto glow plugs, providing faster, better-quality starts and more complete cold-start combustion for reduced emissions
Improved glow plugs heat up faster through an independent controller
Revised variable-geometry turbocharger is aerodynamically more efficient to help deliver smooth and immediate response and lower emissions
Air induction system re-tuned to enhance quietness
EGR has larger cooler to bring more air into the system
First application of new, 32-bit E35 controller, which adjusts and compensates for the fuel flow to bolster efficiency and reduce emissions
The Duramax 6600 also has a new intake air heater to reduce smoke and emissions during cold or light-load driving. The system features a 600-watt grid heater located in the air intake duct, which is triggered automatically by the engine controller. It heats up the incoming air to speed warm-up of the engine.

Allison six-speed Tap Shift automatic transmission: The Allison 1000 transmission grows from a five-speed automatic to a six-speed automatic. It's available for 2006 Sierra HD models equipped wîth the Duramax 6600 6.6L V-8 diesel or Vortec 8100 8.1L V-8. The transmission features a class-first range selection function, as well as offering enhanced fuel economy, quietness and control. The range selection function allows the driver to easily select the desired gears to match driving conditions, such as towing a trailer on a steep grade.

The sixth gear – essentially a second overdrive gear – enables a wide, 5.08:1 overall forward gear ratio and allows the vehicle's engine to operate at lower rpm, particularly during higher-speed driving on highways and freeways. Its 0.61 ratio provides a 1550-rpm engine speed at 60 mph, compared wîth the five-speed transmission's 1800-rpm engine speed at 60 mph. The engine uses less fuel at lower rpm, enabling increased fuel mileage and range. The ratios of gears 1 through 5 remain the same as the Allison 1000 five-speed, including the 0.75:1 fifth gear.

A tow/haul mode is retained on the Allison 1000 six-speed, but it is complemented by a new range selection feature that allows the driver to select the desired gears via a thumb-activated switch on the shifter. This provides a feeling of enhanced control in unique driving situations, such as towing on a steep grade. The range selection feature holds the gear pre-selected by the driver and electronic safeguards prevent the transmission from being shifted in a manner that could cause engine damage or loss of vehicle control.

Diesel-engine vehicles equipped wîth the Allison 1000 six-speed feature cruise control grade braking. Working in harmony wîth the tow/haul mode, the cruise grade braking system will automatically downshift to help maintain the pre-selected cruise speed when driving on downhill grades. A new low-traction mode also is standard on vehicles equipped wîth the diesel engine. When the driver selects second gear while stopped and wheel slip occurs, the transmission torque-manages the engine to limit tire slip on slippery road surfaces.

Additional changes for '06

Sierra Hybrid models available nationwide: Previously available in select markets, the Sierra 1500 Hybrid is available nationally in the 2006 model year. The Sierra Hybrid promises up to 10 percent fuel economy improvement through its ability to automatically stop and restart the engine under different operating circumstances. Instead of a conventional starter motor and alternator, the hybrid pickup use a compact 14-kw electric induction motor or starter generator integrated in a patented, space-efficient manner between the engine and transmission. (posted on The starter generator provides fast, quiet starting power and allows automatic engine stops/starts to conserve fuel. (concept carz) It also smoothes out any driveline surges; generates electrical current to charge the batteries and run auxiliary power outlets; and provides coast-down regenerative braking, to improve fuel economy.

The standard Vortec 5300 V-8 engine delivers 295 horsepower (220 kw) and 335 lb.-ft. (463 Nm) of torque – the same as its non-hybrid counterpart – along wîth the capability of acting as a mobile power-generating station, including four 120-volt/20-amp electrical auxiliary power outlets (APO). The power outlets are located under the rear seat of the cab and in the pickup bed. Customers can conveniently operate power equipment without taking up the bed space typical portable generators would use.

Sierra Special Edition: The availability of 20-inch chrome wheels expands on 2WD and 4WD Extended Cab and Crew Cab models via the Sierra Special Edition (B2E). The Sierra Special Edition is available on SLE/SLT trims and includes the Light Duty Power Package (5.3L, automatic locking differential, HD Trailering), 3.73 rear axle, high-performance suspension, automatic climate control and §teering wheel controls. Chrome-clad 16-inch steel wheels are available for 3500 Crew Cab long box models wîth single rear wheels.

Camper mirror: A new power-adjustable glass wîth manual-extending camper mirror is available. This vertical mirror has a larger glass area than previous camper mirrors and manually extends outward to provide a greater view when towing a trailer or camper. It includes heated, power-adjustable flat glass and integrated turn signals. A convex 'spotter mirror' glass also has been added to the mirror, which gives the mirror a 20-inch improved field of view. The vertical design and new spotter mirror section answer customer requests for such a configuration.

Single OnStar/XM antenna: All '06 Sierra models equipped wîth OnStar and XM Satellite Radio have a new, single-unit antenna that eliminates the need for two separate antennas.

Exterior colors: Steel Gray Metallic and Stealth Gray Metallic have been added to the list of exterior color choices.

Diverse lineup

The GMC Sierra is offered in a diverse array of configurations, including regular, extended or Crew Cab body styles; standard 6-foot 6-inch (2 m) or extended 8-foot (2.4 m) cargo boxes, along wîth the new 5-foot 8-inch short box. Half-ton, three-quarter-ton and one-ton models deliver tremendous payload and towing capability for almost any need.

An impressive array of Vortec engines is offered in 1500 models: a 4300 4.3 L V-6; 4800 4.8L V-8; two models of the Vortec 5300 5.3L V-8; and the powerful Vortec 6000 6.0L V-8. Engine output ranges from 195 hp (145 kw) all the way up to 345 hp (257 kw) in the Sierra Denali. The workhorse Vortec 8100 V-8 and Duramax Diesel 6600 engines pull more than their weight in heavy-duty models.

In addition to the hybrid version, Sierra can also be ordered in several reduced-emissions or alternative-fuel variations. All Sierra models wîth the Vortec 4300 4.3L V-6, and those sold in California wîth the Vortec 4800 4.8L or Vortec 5300 5.3L V-8, have a robust catalytic converter system that meets Últra Low Emission Vehicle (ÚLEV) standards. ( posted on Models equipped wîth the Vortec 6000 6.0L V-8 come wîth a dedicated compressed natural gas (CNG) or bi-fuel system that can run on CNG or gasoline.

Light-duty Sierra models wîth the Vortec 5300 5.3L V-8 offer an option that enables owners to operate them on varying blends of ethanol and gasoline, up to a maximum of 85 percent ethanol.

Sierra also can be equipped to meet any personal requirement or professional demand when it comes to hauling or towing. Payload capacities range from 1,295 pounds (587 kg) all the way to 4,047 pounds (1,836 kg) for 2500 heavy duty models. Gross Vehicle Weight Ratings range from 6,100 pounds (2,767 kg) to 10,100 pounds (4,173 kg) on the 1500 Extended Cab wîth standard-length box and 4WD.

Sierra Heavy Duty pickups offer a wide selection of weight ratings, body styles and powertrain combinations, including diesel and compressed natural gas (CNG) models. At the top of the gasoline engine range is the available Vortec 8100 8.1L V-8, rated at 330 hp (246 kw) and 450 lb.-ft. (610 Nm) of torque. The available Duramax Diesel engine is enhanced for '06 wîth improved performance, smoothness and quietness.

Many Sierra HD models can run on dedicated (CNG) or bi-fuel systems, the latter of which operates on either CNG or gasoline when equipped wîth a Vortec 6000 6.0L V-8 wîth hardened valves and seals to withstand CNG's lack of lubricity and cooling. Special versions wîth reduced gross vehicle weight ratings (8,500 pounds or 3,825 kg) enable customers to meet fleet requirements in 'non-attainment' areas, while GVWR ratings of up to 9,200 pounds (4,173 kg) are available.

With impressive power, tough frames, advanced suspensions and high-capacity brakes, the 2500HD/3500 Series provides outstanding payload capacities as well as outstanding hauling and towing capabilities. The 2500 HD models have a GVWR of as much as 9,200 pounds (4,173 kg), and payloads up to 3,964 pounds (1,798 kg). The 3500

Series pickup models have a GVWR up to 11,400 pounds (5,171 kg) and payloads up to 5,753 pounds (2,610 kg).

For chassis cab models, Sierra HD has an 11,400-pound (5,171-kg) GVWR for 2WD versions and a 12,000-pound (5,443 kg) GVWR when equipped wîth 4WD. Chassis cabs provide payloads up to 6,089 pounds (2,762 kg).

Safety features

All Sierra 1500 models are equipped wîth GM's Passenger Sensing System, which uses the latest sensing technology to turn the front passenger air bag on or off. If the sensor system detects an unoccupied front passenger seat or the presence of a smaller occupant, the front passenger air bag is designed to automatically turn off so it would not deploy in the event of a frontal collision. A status indicator on the inside rearview mirror alerts occupants that the passenger air bag is on or off. Even wîth this system, GM strongly recommends restraining child passengers in an appropriate child seat placed in the rear of the vehicle. Owners should never install a rear-facing infant seat in front of an active air bag. GM also recommends that all children 12 and under ride in the rear seat when possible.

The GMC Sierra also has dual-stage frontal air bags (not available on 1500HD Crew Cab, 2500HD and 3500 Series models) for supplemental protection for front seat passengers. Dual-stage frontal air bags are designed to help reduce the risk of air bag-induced injury. When the air bag system's control unit detects an impact, it determines whether the crash is severe enough to trigger a deployment, and whether the primary amount of inflation is sufficient. The primary stage alone will deploy in most frontal impacts requiring the supplemental protection of an air bag, while a secondary stage is designed to deploy in more severe frontal collisions.

For '06, GM's OnStar safety and security system is available wîth the OnStar Plus Package, which is available on SLE and SLT light duty models. In the heavy-duty range, OnStar is available on SLE and SLT 2500 HD and 3500 models. OnStar is standard on Sierra Denali. OnStar-equipped Sierras feature OnStar dual-mode (analog-digital) equipment. OnStar's digital equipment also includes enhanced hands-free voice recognition capabilities including more intuitive continuous digit dialing and improved voice recognition accuracy. OnStar is the leading provider of in-vehicle safety, security and information services in the Únited States and Canada . Úsing the GPS satellite network and wireless technology, OnStar features core safety services and OnStar Hands-Free Calling that allows drivers to make and receive voice-activated phone calls using an externally mounted antenna for greater reception.

Additional safety and security systems include electronic traction control on 2WD Sierra models to enhance handling and response on models equipped wîth a V-8 engine, automatic transmission and locking rear differential. All models come standard wîth PASSLock II theft deterrent system, and a driver information center that monitors and reports on numerous vehicle system functions.

Air conditioning, chrome front bumpers, tinted glass, power §teering wîth tilt-adjustable column, a full-size spare tire and heavy-duty battery also are standard on all Sierra models.

Impressive entertainment options

Numerous entertainment systems – from available Bose sound systems to a Panasonic DVD passenger entertainment system – add to Sierra's comforts. These systems (except the base fleet radio) feature the next-generation Radio Data System, and can interface wîth services such as the optional XM Satellite Radio. On Crew Cab models, available rear-seat audio controls allow second-row passengers to enjoy a separate audio source from front-seat occupants.

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 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.

• 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 wîth 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 wîth 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 wîth 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 '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 wîth the Yukon, Yukon Denali SÚVs and the Sierra pickup. The Sierra Heavy Duty pickups are the most capable and powerful trucks in the market.
