Chronology
Predecessor	Chevrolet/GMC C/K

The Chevrolet Silverado (along with its GMC counterpart, the GMC Sierra), is the latest line of full-size pickup trucks from General Motors.

As of 2007, the Silverado pickup is the 2nd largest volume vehicle in the United States, behind the Ford F-Series pickup truck. Combined with platform-mate GMC Sierra, the platform usually outsells the Ford F-Series, which is actually made of two different platforms for standard and heavy duty models, not counting SUV derivatives such as Suburban, Tahoe, Escalade, or Yukon. For the first half of 2008, 231,320 Silverados were sold in the U.S., compared with 274,713 Ford F-Series. With 83,174 GMC Sierras also sold in the same period, the GM vehicles outsold the Ford pickups by 14.5% (compared to just over 15% for the same period of 2007).

History

Although General Motors introduced its first pickup truck in 1930, the term "Silverado" was a designation only used to detail the higher-level trim for the Chevrolet C/K pickup trucks from 1975 through 1999. GMC used a few variations of the "Sierra" name (Sierra, High Sierra, Sierra Grande, Sierra Classic) to distinguish the different trim levels through 1987, though the "C/K" nomenclature was continued through 1999. "C" (or "R" for 1987) trucks had rear-wheel drive while "K" (or "V" in 1987) models had four-wheel drive. Both Chevrolet and GMC dropped the "C" and "K" designations in 1999.

The Chevrolet Silverado and GMC Sierra trucks have been essentially the same for their entire history. The Silverado today is generally advertised as the "lower" version, while the Sierra has more luxury options. There are some trim and option variations as well. Early models included variations in the engine and equipment, but the present differences are slight. The 1999 redesign included different grilles and interior trim, and certain features (e.g. Quadrasteer) were included at different times on the two trucks.

The GMT800 Silverado/Sierra 1500 (light pickup trucks) were released in 1998 as 1999 models. The "classic" light-duty GMT400 C/K trucks were continued in production for that first year alongside the new models, and the Heavy-Duty GMT400 pickups (alongside the GMT400 SUVs) were continued through 2000, with the new GMT800 Silverado/Sierra HD (Heavy Duty) introduced in 2001.

Light duty

There are a number of models of light-duty Silverados and Sierras, including the half-ton, SS, and Hybrid.

The light-duty trucks generally use the 1500 name. They are available in three cab lengths, 2-door short cab, 3 or 4-door extended cab, and front-hinged 4-door crew cab. Three cargo beds are available, including a Template:Auto in short box, Template:Auto in standard box, and a Template:Auto in long box. The short box is only available with the extended or crew cab, and is the only option on the latter.

For the first year, only the regular cab and 3-door extended cab were available, along with the Vortec 4300 V6 (regular cab only), Vortec 4800 V8, and the Vortec 5300 V8. A 4-door extended cab was added for 2000, and output on the 5.3 L engine increased by 15 hp (11 kW) and 10 lb⋅ft (14 N⋅m).

The 6.0 L Vortec 6000 V8 was added for the 2001 Heavy Duty models, rated at 300 hp (224 kW), with the GMC Sierra 1500 C3 getting an uprated 25 hp (19 kW) version of this engine. The Silverado Z71 got an optional lighter composite box, with a suspension package for towing, but lacked the high-output engine. The C3 became the Denali for 2002, and Quadrasteer was added.

GM launched a reworked version of the Silverado/Sierra in 2003, with a new front end, and a slightly updated rear end.

GMC Sierra C3/Denali

Sierra Denali with Quadrasteer

GMC created an upscale version of its Sierra 1500 in 2001 called the Sierra C3. It used all-wheel drive and included the 6.0 L Vortec 6000 V8 rated at 325 hp (242 kW) with other upscale equipment. For 2002, the name was changed to Sierra Denali, but the specifications remained essentially the same except for the addition of Quadrasteer. The Denali received the 345 hp (257 kW) Vortec 6000 engine, previously used in the Silverado SS.

The Denali is rated for towing 8,100 lb (3,674 kg) and hauling 1,575 lb (714 kg) in the cargo box.

The Sierra Denali was initially equipped with Delphi's Quadrasteer system as standard equipment. It was a 4-wheel steering system that greatly reduced the truck's turning radius and improved lane changing while towing. General Motors dropped Quadrasteer from its entire lineup after 2005 due to poor sales of this expensive option.

For the '07 model year, the Sierra Denali shares the same bullet grille from the other Denali models, and also has the same dash as the '07 SUV's. The '07 Sierra Denali is the only half ton pickup that has a 6.2 liter with 403 hp (301 kW) and Template:Auto lbft of torque coupled to a six speed transmission. This truck is also an all wheel drive vehicle and goes 0-60 mph in 6.3 seconds.

Chevrolet Silverado SS

Silverado SS

Launched in 2003, the Silverado SS is a high-performance pickup truck built by Chevrolet. It is based on the standard 1500 Silverado, with upgrades in drive train and both exterior and interior appearance. It uses the 6.0 liter Vortec High-Output V8 rated at 345 hp (257 kW) at 5200 rpm and Template:Auto lbft of torque at 4000 rpm. This was the same engine used for the second generation Cadillac Escalade. Chevrolet and GMC advertise this engine as the "VortecMAX", while Cadillac calls it the "HO 6000". The SS debuted with a standard All Wheel Drive setup, but was later changed to the current Rear Wheel Drive only format. The Silverado SS also comes with the Z60 performance suspension and 20 inch chrome wheels. In 2006, Chevrolet released a special edition Silverado SS under the name "Intimidator SS" (licensed by Dale Earnhardt Inc.) that came with several minor appearance upgrades, but left the bulk of the truck the same.

Vortec High Output / Vortec Max

2004 GMC Sierra with VHO package

The Vortec High Output (also know as the VHO by some enthusiasts) was first introduced in 2004 to a limited market (mainly consisting of Texas and several surrounding areas). The VHO package (under option code B4V) included several options previously not found on the standard 1500 model, most notably the LQ9 6.0 L V-8 engine (the same used for the Silverado SS and the Cadillac Escalade). The LQ9 motor was rated at 345 hp (257 kW) at 5200 rpm and Template:Auto lbft of torque at 4000 rpm, which was the same specifications shared in the SS models. The package also included one style of the newly introduced GM 20 inch wheels installed from the factory. The B4V package could only be ordered on an extended cab, light duty, 2 wheel drive Silverado or Sierra. This marked the first time the LQ9 engine was available for a two wheel drive application. For the 2006 model year the Vortec Max package replaced the VHO with an array of similar features and new badges. It was also made available for crew cab models (in addition to the extended cab) and customers were able to purchase these trucks outside of the original market of the VHO. The Vortec Max Performance package boasts an industry leading 10,500 pounds towing capacity.

Hybrid

The engine compartment of a 2006 GMC Sierra Hybrid

GM launched a hybrid version of the Silverado/Sierra in 2005, becoming the first ever GM hybrid vehicle. It is a mild hybrid design, with the electric motor serving only power accessories and the system also automatically shuts down when the truck brakes below 13 mph (21 km/h), and uses electric power to restart it. It uses three extra 14 V batteries mounted under the rear seats to store power. The truck uses a 5.3 L Vortec 5300 V8 for primary power.

The truck features four 120 volt 20 amp AC outlets mounted in the bed. These are particularly interesting to the building/construction contractor market, since they often require AC power when on the job. Additionally, the extra reserves of power for the accessories make this truck well-suited to that market, where trucks often sit at idle for hours at a time.

Availability was extremely limited at first, with commercial buyers getting the first allotment. Later in 2005, the truck was offered at retail in Alaska, California, Florida, Nevada, Oregon, and Washington. Finally, for 2006, the truck was generally available to retail buyers in all US states.

The HD variant is a heavy-duty light truck. It is a strengthened version of the Silverado/Sierra light-duty, and is available in the 1500HD, 2500HD, and 3500 models. The 1500HD, introduced in 2001, offers a Vortec 6000 V8 with 300 hp (224 kW) at 5200 rpm and Template:Auto lbft of torque at 4000 rpm with a Hydra-Matic 4L80E four-speed automatic transmission. The 2500HD also offers an available Duramax V8 with 360 hp (268 kW) at 3000 rpm and Template:Auto lbft of torque at 1600 rpm. Also available is the Vortec 8100 V8 with 340 hp (254 kW) at 4200 rpm and Template:Auto lbft of torque at 3200 rpm.

The 2500HD has an available five-speed (six-speed for 2006-2007 models) Allison 1000 transmission. The Silverado 3500 offers the same engine/transmission features that the 2500HD does, however it is usually equipped with "dually" twin wheels at the rear and has a stronger suspension and axle. The HD models are primarily used for towing and high-weight cargo.

Towing capacity for the 1500HD is rated at 10,300 lb (4,672 kg), and can haul 3,129 lb (1,419 kg) in the bed. The 2500HD ups these ratings to 16,100 lb (7,303 kg) with the 8.1 liter engine or 10,600 lb (4808 kg) with the 6.0 liter engine, and 4,058 lb (1,841 kg), while the 3500 can tow 16,700 lb (7,575 kg) and haul 5,511 lb (2,500 kg). The addition of 4 wheel drive tends to reduce the towing and carrying capacity by 200 to Template:Auto lb, depending upon year and model. Other factors, such as options, can also affect these numbers.

The redesigned GMT900 generation of the Silverado/Sierra arrived in the last quarter of 2006 as a 2007 model. It features a redesigned exterior, interior, frame, and suspension as well as a power increases on certain engines. It takes styling cues from the 2007 GMT900 SUVs and the Chevrolet Colorado pickups. Like the GMT900 SUVs, these pickups also have greatly improved aerodynamics over their predecessors like steeply raked windshields and tighter panel gaps which improve fuel economy. The GMT800 models were continued in 2007 badged as "Classic", just as the GMT400 models continued for a year after the GMT800's introduction.

The new Silverado earned the North American Truck of the Year award for 2007 and was Motor Trend magazine's Truck of the Year for 2007. The half-ton Silverado has a starting price of $18,760 USD with its sibling, the GMC Sierra, being priced very similarly. Pricing for the Heavy Duty version begins at $24,575 for the 3/4-ton models, and $28,785 for the one-ton models. Like its predecessors, the new Silverado offers buyers a choice of two door regular cabs, four door extended cabs (with rear doors that now open 170 degrees similar to the Nissan Titan) and four door crew cabs with the rear doors opening in the same direction as the front doors. GM also offers the trucks in the traditional two and four wheel drive configurations.

The Generation III small block V8 engines offered in the GMT 800 trucks will be replaced in the GMT 900 series by the Generation IV small block V8 engine family, featuring upgrades such as increased power and Active Fuel Management on the 5.3 L and 6.0 L V8s. A new high performance 6.2 liter V8 (with 403 hp (301 kW) and Template:Auto lbft of torque) was introduced with the 2007 Cadillac Escalade and 2007 GMC Denali line. After skipping the 2008 model year, with 2007 being the last for the GMT800 hybrid line, a two-mode hybrid model will be introduced in early 2008 as a 2009 model. One notable omission is that the 8.1L big-block V8 is no longer offered on the Heavy Duty models, and no replacement has been announced.

The majority of the GMT 900 trucks continue to be equipped with the four speed transmission that was found on the GMT 800 platform. A more modern 6L80 6-speed transmission is standard equipment on the GMC Sierra Denali and the similar 6L90 is standard in all Heavy Duty models. As production capacity is established, 6-speed transmissions are expected to replace 4-speed transmissions on the most truck models in coming years.

There are two dash options offered in the new Silverado and Sierra. A luxury-inspired dash that closely mimics the dash in their GMT900 SUVs, and a "pickup" dash that is more upright to make way for a passenger seat in place of a center console.

As of 2008, General Motors full size trucks are no longer sold in United States and Canada with manual transmission, only offered in Mexico in Silverado 1500 V6 engine and Silverado 3500.

Military applications

A military version of the 2003 Silverado is called MILCOTS (Militarized Commercial Off-The-Shelf or colloquially as the "Milverado") and is being purchased by the Canadian Forces. CF has ordered 861 units from GM Defense. A similar but more armoured platform is being used by the US Army under the COMBATT (Commercially Based Tactical Truck]] program.

Marketing

Like a Rock campaign

Like a Rock campaign emphasized Chevrolet Silverado as the best-selling, longest lasting truck on the road. The campaign ended in the 2004 model year. The jingle was Like a Rock by Bob Seger.

Our Country. Our Truck. campaign

On September 26, 2006, Chevrolet announced plans for a multi-media marketing campaign to support the 2007 Silverado full-size pickup as an extension to Chevrolet's An American Revolution campaign. The full campaign began on October 21, 2006 and featured the new tag line Our Country. Our Truck. The advertising videos used John Mellencamp's Our Country as their theme song. Two ads premiered during NBC's new Sunday Night Football in America.

The first video, named Anthem, was designed to showcase the good and bad of the past half century and how America has made it through difficult times. The video is filled with images of historic moments in recent American history, such as a nuclear explosion, Rosa Parks on a bus, Martin Luther King giving a speech, the site of the former World Trade Center in the months after 9/11, Hurricane Katrina's devastation, then shows the trucks working to rebuild the devastated places, and ends with the tagline: This is our country. This is our truck. The final broadcast version did not include images of the nuclear explosion nor of the World Trade Center. Anthem has been criticized for using black rights activists to sell trucks and implying that there was a parallel between the struggles of the United States and the ongoing struggle General Motors is facing in today's marketplace. However, a representative from GM stated that this was not the intent of the advertisement. Rather, the intent was to show how the trucks are used for work purposes, and the main audience for these trucks is for work. The second video, titled Birthplace, showed average American developing vehicles by unconventional means.

The campaign also included a 28 minute long infomercial, premiered on 2006-12-9. The infomercial starred former NFL football player Howie Long and Gary White, General Motors' North American vehicle line executive for full-sized trucks. The infomercial premiered on channels such as Speed Channel. A 24-page publication was to be included with magazines such as Motor Trend, Field & Stream and Popular Science.

In January 2007, a Canadian version of Silverado ad started to appear, which was based on a variant of Birthplace previously shown on American channels. The ad uses a squared fonts for the texts, with images of forklifting timber, boy scouts, Dale Earnhardt, 'This is Our Chat Room' replaced by a skating hockey player, lighthouse on a rocky shoreline, and hockey player Bobby Orr. At the end of the video, the message was replaced by The Next Generation Chevy Silverado. The ad was being criticized for being unoriginal, and not truly reflecting Canadian values.

After winning the 2007 Motor Trend Truck of the Year award, another version of the ad showed the Silverado itself, with the message 2007 Motor Trend Truck of the Year at the end. Canadian version of the ad only has cosmetic and slogan changes after the Silverado had won its award.
