Chevrolet Silverado

In January 1993, GM began development on the GMT800 pickup program with numerous teams coming together. A new design was chosen and finalized for production in June 1995, 36 months ahead of the scheduled start in June 1998. Development sign-off was issued in late 1997, with pre-production and series production commencement in June 1998.[6][7]

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

The light-duty trucks use the 1500 name. They are available in three cab lengths, 2-door standard/regular cab, 3 or 4-door extended cab, and front-hinged 4-door crew cab. Three cargo beds are available: a 69.2 in (1,758 mm) short box, 78.7 in (1,999 mm) standard box, and a 97.6 in (2,479 mm) long box. The short box is only available with the crew cab and extended cab.

For the first year, only the regular cab and a 3-door extended cab were available, along with the Vortec 4300 V6, Vortec 4800 V8, and the Vortec 5300 V8. In 2000, a driver's side door option became available for the extended cab, giving it four doors, and the crew-cab body was added to the lineup in 2004. Output on the 5.3 L engine also increased to 285 hp (213 kW) and 325 lb⋅ft (441 N⋅m).

The 6.0 L Vortec 6000 V8 was standard on the 2500 and was added for the 2001 Heavy Duty models, rated at 300 hp (224 kW), with the GMC Sierra 1500 C3 getting an uprated 325 hp (242 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 introduced a reworked version of the Silverado and Sierra in 2003, with a new front end and a slightly updated rear end. In 2006 the Silverado received another facelift, similar to the HD version introduced in 2005 HD models. In addition to that, Chevrolet has deleted the "Chevrolet" badge off the tailgate that was used from 1998 to 2005. Its SUV counterparts retained the use of the pre-facelift sheet metal. During the 2005 model year, all light-duty GMT800 pickups reverted to front disc/rear drum brakes as a cost-cutting measure; heavy duty trucks and the SUVs retained their 4-wheel disc brakes.

The Insurance Institute for Highway Safety (IIHS) gave the Silverado an overall "marginal" score on the frontal offset crash test for poor structural integrity and poor dummy control, although no injuries were recorded on the dummy's body regions.[8]

Sierra Denali with Quadrasteer

GMC created an upscale version of its Sierra 1500 in 2001 called the Sierra C3. It used all-wheel drive with a 3.73 final drive gear ratio and included the 6.0 L Vortec 6000 LQ4 V8 rated at 325 hp (242 kW) at 5000 rpm and 370 lb•ft (502 N·m) of torque at 4000 rpm coupled to a 4L60E-HD four-speed automatic transmission along 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 and GM changed from the 4L60E-HD to the 4L65E in conjunction with a 4.10 final drive gear ratio.

The Denali is rated for towing 10,000 pounds (4,500 kg)[9] and hauling 1,840 pounds (830 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 the Sierra Denali after the 2004 model year and its entire lineup after 2005 due to poor sales of this expensive option.[10]

Silverado SS

Launched in early 2003, the Silverado SS is a high-performance pickup truck built by Chevrolet. It is based on the Silverado 1500 Extended Cab with a Fleetside Box and features upgrades in the drive train and both exterior and interior appearance. It was equipped standard with the 6.0 liter Vortec High-Output V8 rated at 345 hp (257 kW) at 5200 rpm and 380 lb⋅ft (515 N⋅m) of torque at 4000 rpm coupled to a 4L65E four-speed automatic transmission. This was the same engine used for the second generation Cadillac Escalade. Chevrolet and GMC advertised this engine as the Vortec High Output and later as the "VortecMAX", while Cadillac calls it the "HO 6000". The SS debuted in 2003 with a standard All Wheel Drive setup with a 4.10 final drive gear ratio and 4-wheel disc brakes. In 2005, in an attempt to increase sales, a 2-wheel drive version became available (the 2WD SS also lost its rear disc brakes in favor of drums, as did the rest of the 1/2-ton GMT800s). 2005 was also the first year the sunroof was available in the SS line up. In 2006, the AWD variant was dropped, and the rear wheel drive was the only driveline layout available. In a further effort to reduce cost, buyers could also choose cloth interior and/or a bench seat. The Silverado SS also comes with the Z60 performance suspension and 20-inch aluminum wheels. All the SS trucks in both 2-wheel drive and AWD used the torsion bar style front suspension for better handling. SS themed trucks were only available from the factory in Black, Victory Red, and Arrival Blue Metallic from 2003 to 2004. In 2005, Arrival Blue Metallic was dropped from the color choices and replaced with Silver Birch Metallic.

In 2006, Chevrolet released a special edition Silverado SS under the name "Intimidator SS" (licensed by Dale Earnhardt, Inc.) to honor the late Dale Earnhardt. The truck came with several minor appearance upgrades (rear spoiler, embroidered headrests, Intimidator custom badging), but was essentially a standard Silverado SS. Of the 1,033 scheduled trucks, only 933 were made (the remaining 100 were sold as 2007 Silverado SS "Classic" body style trucks before the 2007.5 MY changeover. These trucks were only available in Black exterior but could be ordered with cloth or leather interior.[11]

2004 GMC Sierra with VHO package

The Vortec High Output option was first introduced in 2004 to a limited market (mainly consisting of Texas and several surrounding areas); it was available nationwide for MY 2005. It was available for both the Chevy and GMC 1500 series trucks. This special edition 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, the 2005–2006 GMC Denalis and the Cadillac Escalade). The LQ9 motor was rated at 345 hp (257 kW) at 5200 rpm and 380 lb⋅ft (515 N⋅m) of torque at 4000 rpm, which was the same specifications shared in the SS models. The B4V package could only be ordered on extended cab standard box 2WD trucks. They were all built at the Canadian assembly plant and were equipped with the Z60 High Performance suspension package, in addition to the M32 = 4L65E transmission, GT4 = 3.73 rear gear, and G80 Gov Lock as standard equipment. The 2004 models were equipped with the standard 10 bolt 8.625 rear end. The 2005 models were upgraded with the larger 14 bolt 9.5 rear end under RPO option AXN. The package also included one style of the newly introduced GM 20-inch wheels installed from the factory. This marked the first time the LQ9 engine was available for a two-wheel drive application. Unlike the previous years with the SS Package, interior choices ranged from basic cloth to fully loaded. There were also more exterior color options available with this package.

In 2006, the Vortec Max trailering package became available. The Vortec Max package was added to the option list with an array of similar features and new badges, and at its core retained the LQ9/4L65-E powertrain. However, the Vortec Max package differed from the Performance edition in that it also came with a variant of the Z85 Handling/Trailering suspension, as well as 17-inch wheels and tires under the option code NHT (and was available on 4x4 models in addition to 4x2 trucks) versus the Z60 High Performance Suspension and 20-inch wheel and tire package of the regular B4V (which was limited to 2-wheel drive trucks). This was because the Vortec Max package was intended for max trailer towing, while the Performance Edition was intended more for customers who wanted the Silverado SS mechanicals without the visuals of the SS. It was also made available (in addition to the extended cab) in the light-duty 4-door crew cab models. Towing capacity with the VortecMax Trailing package was 10,800 pounds.[12]

The engine compartment of a 2006 GMC Sierra Hybrid

GM launched a hybrid version of the Silverado/Sierra in 2004, becoming the first ever GM hybrid passenger vehicle. Known within GM as the Parallel Hybrid Truck or PHT, it is not actually a parallel hybrid by the current definition, but a type of micro hybrid design. The electric motor housed within the transmission flywheel housing, serves only to provide engine cranking/starting, battery charging, and powering accessories. The engine automatically shuts down as the truck comes to a stop and uses 42 Volt electric power to the starter/generator unit to restart the engine as the brake pedal is released. Besides the typical 12 V automotive battery the PHT uses three additional 14 V valve regulated lead-acid (VRLA) batteries mounted under the rear seat to store and provide power. The truck uses a 5.3 L Vortec 5300 V8 for primary propulsion power. These trucks were also purchased back from customers for more than what they were worth in the late 2000s.

The PHT features four 120-volt 20 amp AC outlets, two in the bed and two inside the cab under the rear seat. 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, Washington and Canada. For 2006–07 the truck was generally available to retail buyers throughout North America. The Parallel Hybrid Truck was discontinued for the 2008 model year with the release of the GMT900 truck line. Starting in 2009, General Motors offers a second-generation Chevrolet Silverado and GMC Sierra equipped with a Two-Mode Hybrid powertrain and CVT.[13]

The HD variant was a heavy-duty light truck. It was a strengthened version of the Silverado/Sierra light-duty, and was available in the 1500HD, 2500HD, and 3500HD models. The 1500HD, introduced in 2000, offered a Vortec 6000 V8 with 300 hp (224 kW) at 5200 rpm and 360 lb⋅ft (488 N⋅m) of torque at 4000 rpm with a Hydra-Matic 4L80E four-speed automatic transmission. The 2500HD also offered the LB7 Duramax V8 with 300 hp (224 kW) at 3100 rpm and 520 lb⋅ft (705 N⋅m) of torque at 1800 rpm, the LLY Duramax V8 with 310 hp (231 kW) at 3000 rpm and 605 lb·ft (820 N·m) at 1600 rpm, and the LBZ Duramax V8 with 360 hp (268 kW) at 3200 rpm and 650 lb·ft (881 N·m) at 1600 rpm. Also available was the Vortec 8100 V8 with 340 hp (254 kW) at 4200 rpm and 455 lb⋅ft (617 N⋅m) of torque at 3200 rpm.

The 2500HD had an available five-speed (six-speed for 2006–2007 models) Allison 1000 transmission with the Vortec 8100 and Duramax 6.6. The Silverado 3500 offered the same engine/transmission features that the 2500HD, however it was usually equipped with "dually" twin wheels at the rear and had a stronger suspension. The HD models were primarily used for towing and high-weight cargo. The Chevrolet Silverado 2500HD came in at #2 in a 2016 study by iSeeCars.com ranking the top 10 longest-lasting vehicles. The Silverado 2500HD had 5.7% of vehicles over 200,000 miles, according to the iSeeCars study.:[14])

For 2002, GMC introduced a new limited edition Sierra Professional. Built as either a 1500 or 2500HD Extended Cab Standard Box model with two and four-wheel-drive, the Professional was the ultimate contractors truck. The center console area provided an area to store PDAs, cell phones and laptop computers as well as extra charging points for them and an area to hang file folders. There were also extra storage trays and larger cupholders throughout the cab, including one temperature controlled cupholder. The exterior featured lower body cladding, Professional badging, and a full-chrome grille. These trucks also featured a standard bedliner, box-rail protectors, in-bed power outlet, and many optional accessories suited to tradesmen (ladder racks, toolboxes, etc.). The 1500 series came standard with the 5.3L Vortec 5300 V8, but the 4.8L V8 could be ordered with an option credit if so desired. 2500HD models came with the 6.0L Vortec 6000 V8 only. All trucks had the four-speed automatic transmission with tow/haul mode. Customers could choose from either SLE or SLT decor. The base price for a 2002 1500 2WD with SLE decor was $29,591. 2003 was the final year the Professional was offered.[15]

Towing capacity for the 1500HD is rated at 10,300 pounds (4,700 kg) and can haul 3,129 pounds (1,419 kg) in the bed depending on options. Towing capacity for the 2500HD is rated at 16,100 pounds (7,300 kg) with the gasoline 8.1L V8 with 3.73:1 rear and can haul 3,964 pounds (1,798 kg) in the bed depending on options. Towing capacity for the 3500HD is rated at 16,700 pounds (7,600 kg) and can haul 5,753 pounds (2,610 kg) in the bed depending on options. The addition of 4 wheel drive tends to reduce the towing and carrying capacity by 200 to 400 lb (181 kg), depending upon year and model. Other factors, such as options, can also affect these numbers.

For 2003, along with all GMT800-based full-size pickup trucks and SUV's, the Chevrolet Silverado and GMC Sierra models received a mid-cycle facelift. All Silverados and Sierras received a revised front end design, as well as new tail lamps, and most models also received new wheel designs. The interior was also redesigned, with a new dashboard design that included a new instrument cluster with an optional enhanced Driver Information Center (DIC), and a new four-spoke steering wheel. New audio system options for 2003 included newly-available XM Satellite Radio capabilities, as well as a Bose premium audio system, and an integrated six-disc CD changer. All trucks also received new front seats with new upholstery designs and color schemes. New for 2003 was a Work Truck (W/T) trim that was offered alongside the Base trim, and later became the new "Base Model" Silverado and Sierra. The Silverado 1500 lineup received a new SS trim that included the 6.0L LQ9 Vortec V8 gasoline engine, while the LT model was divided into 1LT, 2LT, and 3LT trims. Other additions to the powertrain lineup for 2003 included a new E85 (FlexFuel)-capable version of the 5.3L Vortec V8 gasoline engine, which was available in non-California emissions states.

For the first time, the 8.1 L big block V8 is no longer offered on the Heavy-Duty models, and no replacement has been announced. The 6L90 6-speed automatic transmission is standard in all Heavy-Duty models. The Allison 1000 transmission is paired with the optional Duramax V8 diesel.

As of 2011, the GMC and Chevrolet Heavy Duty models have been upgraded with a new fully boxed high strength steel frame from front to rear improving stiffness by 92% with bigger rear springs, larger engine and transmission mounts and new hydraulic body mounts to improve the ride. The front suspension incorporates new upper and lower control arms and new torsion bars tailored to one of five different gross axle weight ratings. Upper control arms are constructed from forged steel that is both stronger and lighter than the previous arms, while the new lower arms are cast iron to maximize load capacity. Using a unique torsion bar for each gross weight rating allows for better control over vehicle height, resulting in improved handling and better alignment for reduced tire wear. These improvements allow for up to a 6,000-pound front axle weight rating, allowing all 4wd trucks to accommodate a snowplow.

Additional front suspension enhancements come from new urethane bump stops, two per side. The upper shock mount has been changed from a single stem mount to a two-bolt design to eliminate the possibility of squeaks and thumps.

The rear suspension design uses asymmetrical leaf springs that are wider and capable of greater load handling. The design features 3-inch-wide leaves, with front and rear spring sections of different lengths to reduce the twisting that can result in axle hop and loss of traction. The 2500HD uses a two-stage design with a rating of 6,200 lb (2,812 kg), and 3500HD models have a three-stage design with 7,050 lb (3,198 kg) and 9,375 lb (4,252 kg) ratings on single and dual-wheel models, respectively.

For the 2011 model year of the Silverado/Sierra, the production of 1500 crew cab models partially moved from Silao, Mexico to Flint, Michigan.[24]

The Silverado comes standard with four-wheel ABS. StabiliTrak and side curtain airbags are optional on certain trim levels.

2007 NHTSA crash test:[25]

The IIHS gave the Silverado a "Good" score in their frontal crash test. The 2007-09 models equipped with or without optional side curtain airbags received a "Poor" rating in the side impact test.[8] For 2010, the side structure was strengthened, side torso air bags were added, and side airbags became standard leading to the IIHS side impact overall rating improving to "Acceptable" and the overall side structure rating improved from "Poor" to "Acceptable".[26] The crew cab variant of the 2011-13 Silverado is also rated "Marginal" in the IIHS roof strength test.[27]

In 2011 developer of the Chevrolet Volt and former vice chairman Bob Lutz joined VIA Motors in developing electric versions of the Chevrolet Silverado/GMC Sierra called VIA VTrux.

For the 2015 model year, the 6.2L EcoTec3 was paired with the new 8-speed 8L90 transmission, offering a wider ratio spread with more closely spaced gears, quicker shifts, and improved acceleration and fuel economy.[37] The Silverado 2500/3500 HD models continue to use the 6.0L L96 flex fuel capable Vortec engine combined with the 6l90e transmission, installed with engine oil and transmission fluid coolers for hauling/towing applications. The 6.6L Duramax also continued to be backed by the 6-speed Allison 1000 automatic.[31][38]

The GMC Sierra 2500HD/3500HD were the first "heavy-duty" trucks to offer an Adaptive Cruise Control (ACC), a Forward Collision Warning System (FCWS), and a Lane Departure Warning System (LDWS) available together as part of the available Driver Assist Package. The Driver Assist Package was standard equipment on the GMC Sierra 2500HD/3500HD Denali, and optional on most other Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD models. Other new options for the Silverado and Sierra 2500HD/3500HD models included an eight-inch, full-color, reconfigurable LCD Driver Information Center (DIC) screen (for Sierra 2500HD/3500HD Denali models only), a 110-Volt AC household-style power outlet, up to six available USB ports, an available eight-inch touchscreen infotainment system, and a power-sliding rear window with integrated defroster.

In mid-year 2015, Chevrolet and GMC made enhancements to the all-new Silverado 2500HD/3500HD and Sierra 2500HD/3500HD. Some of these enhancements included a new OnStar telematics system with 4G LTE Wi-Fi capabilities, new wheel designs, new exterior paint color options, new exterior tow mirror designs, a USB port added the glove compartment of trucks equipped with a front bench seat, DURALIFE brake rotors, the availability of dual 150 and 220 amp alternators for models equipped with the 6.6L Duramax Turbodiesel V8 engine, an off-road information screen added to the instrument cluster of 4X4 models equipped with the Z/71 or All-Terrain Packages (the latter is a GMC-only option), a Bi-Fi Compressed Natural Gas (CNG) option for models equipped with the 6.0L Vortec gasoline V8 engine, a new All-Terrain Package available on SLE and SLT Double Cab and Crew Cab models (for GMC models only), a standard heavy-duty locking rear axle for all models, and the removal of HD Radio from the "up-level" IO5 and IO6 infotainment systems. A Regular Production Option (RPO) Code of "AVF" in the upper glove compartment distinguishes early-build 2015 models from their 2015.5 successors.[39]

For 2015, Chevrolet introduced Special Edition for the Silverado truck series. They are in the following series of Rally Edition 1 and 2, Midnight Edition, Custom Sport Edition, Custom Sport Plus Edition, Black Out Edition, and Texas Edition.[40]

2016 Chevrolet Silverado LTZ Z71

2017 Chevrolet Silverado LT rear

For 2016, the Chevrolet Silverado 1500 and GMC Sierra 1500 received its first mid-cycle refresh. The refreshed Silverado and Sierra received a new grille, new headlights and new front fascia, with design influences from the 2015 Chevrolet Colorado, as well as all-new LED taillights on the 2016 Silverado LTZ and High Country, 2016 GMC Sierra SLT and Denali trim levels while the 2016 Chevy Silverado LT trim levels and below still have the pre-facelifted incandescent taillights along with the 2016 GMC Sierra SLE trim levels and below. Silverado 1500 LTZ and High Country, as well as Sierra 1500 SLT and Denali models equipped with LED headlights, can be optioned with the Intellibeam high beam assist system. On October 1, 2015, HD Radio was added to the Silverado, Sierra, and their HD level models. The Silverado/Silverado HD will add HD Radio to their 8-inch MyLink system as a standard on the LT and LTZ trims, while the Sierra/Sierra HD will include the feature in its IntelliLink system as a standard on all its trims. 2016 Silverado and Sierra models optioned with the 8-inch touch screen feature Apple CarPlay and Android Auto capability. Trucks ordered with bucket seats and center console now feature a wireless charging pad on the console lid.[41] New color options for the Silverado include Iridescent Pearl Tricoat (1500 only), Autumn Bronze Metallic, Siren Red Tintcoat and Red Hot. Sierra's new colors include White Frost Tricoat (1500 only), Mahogany Metallic, Crimson Red Tintcoat and Cardinal Red.

For that year, Chevrolet has added and dropped some of the Special Editions for the Silverado truck series. They are in the following series of Rally Edition 1 and 2, Midnight HD Edition, Midnight Edition, Custom Sport HD Edition, Realtree Edition, Custom Sport HD Edition, and Special Ops Edition.[40]

For the 2017 model year, Silverado and Sierra HD models equipped with the 6.6L Duramax Turbodiesel V8 (L5P) received a new front hood with air intake vents. Gasoline-powered models now have a capless fuel fill. Sierra HD now features standard HID headlamps on all trim levels. New colors include Graphite Metallic and Pepperdust Metallic (Chevrolet) or Dark Slate Metallic and Pepperdust Metallic (GMC). Jet Black/Medium Ash Gray interior trim is added for Silverado High Country. Low-Speed Mitigation Braking is added to the Driver Alert Package for both Silverado and Sierra.[42]

All Silverado and Sierra models receive slight changes to their MyLink (Chevrolet) and IntelliLink (GMC) infotainment systems. The interior backlighting on GMC Sierras changes from red to blue. 2017 Silverado and Sierra Double and Crew Cabs also get a few new safety features, including GM's Rear Seat Reminder,[43] and Teen Driver Mode.[44]

Starting in 2016, GM offered an eAssist mild hybrid version of the 5.3L V8 engine in the Silverado LT and Sierra SLT, but only in the state of California. The engine came with an 8-speed automatic transmission and has the same horsepower and torque as the regular 5.3 V8.[45] For 2017, it was also available in Hawaii, Oregon, Texas, and Washington. For 2018, it became available nationwide and was also offered in the Silverado LTZ.[46]

In late 2014, Chevrolet released the 2015 Silverado SSV (Special Service Vehicle) to complement its lineup of law enforcement vehicles. The SSV Silverado is available in 1500 Crew Cab form with either the short (5.5') or standard (6.5') cargo box. The 5.3L EcoTec3 V8 is the only engine option, and the truck is based on WT trim. It features beefier brake rotors, upgraded oil coolers, high output alternator, auxiliary battery and an upfitter friendly interior.[47]

In 2016, GMC introduced the Sierra All Terrain X, which is equipped with a 5.3-liter V8 engine with performance exhaust, increasing power from 355 to 365 horsepower. On the exterior, the Sierra All Terrain X features black 18-inch rims fitted with larger 265/65R18SL Goodyear Wrangler Duratrac MT tires, black bed-mounted sport bar, LED off-road lights, and blacked-out accents.[48]

After introducing the Sierra 1500 All Terrain X full-size pickup and the Canyon All Terrain X small pickup, in 2017 GMC extended the same formula to its heavy-duty pickup family with the Sierra HD All Terrain X.

Available on four-wheel drive Sierra 2500 HD crew cab models come in either Black Onyx or Summit White exterior colors.

All Terrain X models have a body-color grille surround and a grille insert that's unique to All Terrain. Body color door handles, front and rear bumpers, and bodyside moldings, and black accents, including belt moldings, front bumper skid plate, and B-pillar accents, give it a monochromatic appearance.

Sierra HD All Terrain X models also include eighteen-inch black-painted aluminum wheels – fitted with LT275/65R18 Goodyear Duratrac MT-rated tires – along with four-inch black sport side steps, black heated and power-folding trailering mirrors with integrated turn signals and LED guidance lamps, a spray-on bedliner, and a black bed-mounted sport bar, which is designed to support available GMC Accessories LED off-road driving lamps.

Inside, the 2017 Sierra 2500 HD All Terrain X has GMC IntelliLink with an 8-inch-diagonal color touchscreen, Teen Driver, remote-locking tailgate, remote starting system, Rear Vision Camera, adjustable pedals, leather-trimmed seats, heated front seats and wireless mobile device charging.

A 6.0-liter gasoline engine is standard, but the 6.6-liter Duramax Diesel turbo-diesel V-8 is also available. This delivers 445 hp and 910 lb-ft of torque.

The Sierra HD All Terrain X also includes the Z71 off-road suspension package, which adds front underbody and transfer case skid plates, twin-tube Rancho shocks, hill descent control, and off-road information graphics in the Driver Information Center. An Eaton automatically locking rear differential (4.10:1) is also standard equipment.[49]

There were several additions to this year's Special Editions for the Silverado series shown in boldface. They are the following series of Midnight, Midnight HD, Rally 1, Rally 2, High Desert, Custom Sport HD, Realtree, Special Ops, Alaskan (Available on HD series only), Redline and Black Out. The remaining Special Edition listed in the 2017 Chevrolet Silverado brochure were All Star Edition and Texas Edition.

New for 2017 was the High Desert option package. This package brought a new innovative lockable storage system into the bed of the Silverado 1500 Crew Cab model. The system includes a three-piece hard tonneau cover, dual lockable storage bins on each side of the truck bed, and a removable bed divider to keep items separate and from moving around the truck bed while the vehicle is in motion. Avalanche-like plastic fairings were also added to the rear of the cab. The High Desert package was available on both two-wheel-drive and four-wheel-drive LT, LTZ, and High Country trim levels. It was not available on LTZ models with the Z71 off-road package. LT models with the High Desert package receive the same LED taillamps as the LTZ, and High Country trims. Magnetic Ride Control is optional on High Country High Desert.

To commemorate the 100th anniversary of Chevy Trucks, GM introduced special edition models of the Chevrolet Silverado and the smaller Chevrolet Colorado.[50]

Chevrolet introduced the Centennial Edition Chevrolet Silverado for 2018. Only available in a Crew Cab Short Box LTZ Z71 configuration, the Centennial Edition added Centennial Blue Metallic paint, 22-inch painted-aluminum wheels with chrome inserts and special 100-years Chevrolet Bowtie emblems.[50] In addition to the Centennial Edition, the remaining Silverado Special Editions were virtually unchanged from the last year model.[40][51]

Chevrolet continued production of the third-generation Silverado 1500 for 2019, which was sold alongside the all-new, fourth-generation 2019 Chevrolet Silverado 1500. Renamed the Chevrolet Silverado LD ("LD" for Light Duty), production of the previous-generation truck moved from Fort Wayne, Indiana to Oshawa Car Assembly, Ontario, Canada. Only available in a Double Cab/Standard Box configuration, the Silverado LD ended production in December 2019.[52]

The first-generation Chevrolet Silverado 1500 was sold alongside the second-generation Chevrolet Silverado 1500 for the 2007 model year as the Chevrolet Silverado 1500 Classic, and 2500 and 3500 versions of the truck were also sold alongside their successors, the Chevrolet Silverado 2500 and 3500. GMC also offered versions of their Sierra trucks as the Sierra Classic for 2007 as well, and will do the same for 2019, offering the predecessor generation model as the 2019 GMC Sierra 1500 Limited.[53]

The Silverado 1500 will be available in eight distinct trim levels: WT, Custom, Custom Trail Boss, LT, RST, LT Trail Boss, LTZ, and High Country.[61]

All trim levels include a next-generation touchscreen infotainment system with Apple CarPlay and Android Auto, Bluetooth for hands-free calling and wireless audio streaming via A2DP, power windows and door locks (on Double and Crew Cab models), air conditioning, and a rearview backup camera system. Additional features available on select trim levels include GPS navigation, SiriusXM Satellite Radio and Travel Link, OnStar with 4G LTE in-vehicle Wi-Fi, a Bose premium audio system with seven speakers, keyless access and push-button start, a remote starter system, heated and ventilated luxury leather-trimmed seating surfaces, a heated leather-wrapped steering wheel, driver-assist technologies, a multi-angle camera system, and heated rear seats.

For 2020, the Rally and Midnight Special Editions return after being absent for the 2019 model year. Rally Edition is available on Silverado Custom and RST trims. The package features black Rally Stripes on the hood and tailgate, black CHEVROLET tailgate lettering, and black assist steps. The Midnight Edition features Bucket Seats with Console, special headlamp bezels, black dual exhaust tips, and black assist steps. The Midnight Edition is only available on the LT Trail Boss trim level.[62]

In January 2020, Chevrolet and Realtree announced the 2021 Silverado 1500 Realtree Edition. This is the second-time Chevrolet and Realtree have teamed up to produce a special edition Silverado truck, having done so for 2016. The 2021 model is based on a Silverado 1500 Crew Cab Custom Trail Boss, adding 20-inch black wheels and Realtree camouflage graphics inside and out.[63]

Rear view

The all-new 2019 Chevrolet Silverado and GMC Sierra 1500 offers a choice of six different engine options, dependent upon trim level. The base engine on lower trim levels is the 285-horsepower, 4.3L EcoTec3 FlexFuel-Capable V6 gasoline engine. Standard on mid-level trims is an all-new, 310-horsepower, 2.7L Turbocharged Inline Four Cylinder (I4) gasoline engine that is the smallest engine available on a half-ton pickup, and features cylinder deactivation for improved fuel economy. Optional on most trim levels is the 355-horsepower, 5.3L EcoTec3 V8 gasoline engine, which is optionally FlexFuel-Capable, and features either a carryover Active Fuel Management (AFM) system, or a brand-new Dynamic Fuel Management system (DFM), which now can shut off up to 6 of 8 cylinders. The availability of either AFM or DFM is dependent on trim level, with WT and Custom trucks available with AFM, and LT and above trucks standard with DFM. Optional on upper-level trims is a 420-horsepower, 6.2L EcoTec3 V8 gasoline engine with Dynamic Fuel Management (DFM). An all-new, 277-horsepower 3.0L Turbocharged Duramax I6 engine became available for the 2020 model year. Availability of this engine had been delayed due to EPA certification. All engines are paired to either a 6-speed, 8-speed, or 10-speed automatic transmission, with a choice of either two-wheel-drive or four-wheel-drive (4X4 is standard equipment on Silverado 1500 Custom Trail Boss and LT Trail Boss trims, and optional on all other Silverado 1500 and Sierra 1500 models). For 2020, availability of both the 6.2L EcoTec3 V8 gasoline engine and the 10-speed automatic transmission will expand to most Silverado 1500 and Sierra 1500 trim levels.

According to EPA ratings, rear drive 2019 Silverado models with the 2.7-liter turbo-four engine can achieve 20/23 mpg city/highway.[64]

Standard features include a next generation infotainment system with Apple CarPlay and Android Auto. The Waze mobile app can now be compatible in its infotainment system through the use of CarPlay.[65]

A seven-inch infotainment system is standard on Chevrolet Silverado 1500 W/T, Custom, and Custom Trail Boss models, as well as the GMC Sierra 1500 Base (Sierra) model, while an eight-inch infotainment system is standard on the Silverado 1500 LT, LT Trail Boss, RST, LTZ, and High Country models, as well as the Sierra 1500 SLE, SLT, AT4, and Denali. SiriusXM Satellite Radio, OnStar with 4G LTE Wi-Fi, a seven-speaker Bose premium audio system, HD Radio, GPS navigation, SiriusXM Travel Link, and a multi-angle camera system are all available depending upon the trim level selected. For 2020, Silverado and Sierra models add SiriusXM 360L compatibility.

Crew cab Silverado models increase in payload up to 14 percent, or 340 pounds.[66]

Trailering features equipped for the 2019 model includes an industry's first VIN-specific trailering and payload label and an in-vehicle towing app on its GM infotainment system.[67]

Advanced, active safety features included in the 2019 Chevrolet Silverado are:

• Lane Change Alert with Side Blind Zone Alert
• Front and Rear Park Assist
• Lane Keep Assist
• Low-Speed Forward Automatic Braking
• IntelliBeam headlamps, high-beam assist
• Front Pedestrian Braking
• Surround Vision 360-degree Camera System

Silverado HD LTZ

Chevrolet released three all-new 2020 Silverado models, including the Silverado 2500 HD and 3500 HD, in 2019.[68] Chevrolet debuted the truck at GM's Flint, Michigan plant on February 5, 2019.[69][70] The trucks had made their arrival at the dealerships in the late summer of 2019.

The 2020 Silverado 3500 HD can tow up to 35,500 pounds (16,100 kg) in a regular cab dual rear wheel configuration with the Duramax 6.6L L5P turbodiesel V8 engine.[71]

The fifth-generation GMC Sierra was unveiled in Detroit on March 1, 2018. The Sierra 1500 will differentiate itself from its Chevrolet Silverado 1500 counterpart by offering unique features, such as a two-piece tailgate, a pickup bed constructed from carbon fiber, a 3" x 7" multi-color Heads-Up Display, a rear-view mirror backup camera system, and a luxury Denali trim level. The Sierra 1500 will also feature its own distinct exterior styling, though interior styling will be similar to that of the Chevrolet Silverado 1500.[72]

There are six functions of GMC Sierra's Multi-Pro Tailgate including a primary tailgate load stop for large items. Its inner tailgate can be a load stopper, a full-width step, and a work area by dropping down the load stop or provide easy access to the bed just by folding down the inner tailgate.[73]

Powertrains include improved versions of the current 5.3L and 6.2L EcoTec3 V8 gasoline engines, as well as the same 3.0L Duramax Turbocharged Diesel I6 engine that will also be available in the 2019 Chevrolet Silverado 1500. An all-new, ten-speed automatic transmission will come as standard equipment on gasoline-powered Sierra 1500 models. Availability of the previous 4.3L EcoTec3 V6 gasoline engine was not announced at launch.

All trim levels include a next-generation touchscreen infotainment system with Apple CarPlay and Android Auto, Bluetooth for hands-free calling and wireless audio streaming via A2DP, power windows and door locks (on Double and Crew Cab models), air conditioning, and a rear-view backup camera system. Additional features available on select trim levels include GPS navigation, SiriusXM Satellite Radio and Travel Link, OnStar with 4G LTE in-vehicle Wi-Fi, a Bose premium audio system with seven speakers, keyless access and push-button start, a remote starter system, heated and ventilated luxury leather-trimmed seating surfaces, a heated leather-wrapped steering wheel, driver-assist technologies, a multi-angle camera system, and heated rear seats.

The 2019 GMC Sierra went on sale in September 2018 as an early 2019 model year vehicle at GMC dealerships nationwide.

Initially unavailable at launch, the all-new 2019 Chevrolet Silverado 1500 and GMC Sierra 1500 regular cab configuration went on sale in early 2019. Only available with an 8 ft (2.4 m) pickup box, with a choice of two-wheel-drive or four-wheel-drive and the 4.3L EcoTec3 V6 or 5.3L V8 gasoline engines, the regular cab is exclusively available in W/T trim (1WT) for Silverado 1500, or Sierra (1SA) trim for Sierra 1500. The regular cab option is unavailable in other trim levels in the United States and Canada, as these trucks will appeal mainly towards fleet and commercial buyers. Regular cab models with a 6.5 ft (2.0 m) bed and in higher trim levels are produced but are only available for sale in Mexico and the Middle East.

Standard features include a black front grille, black front and rear bumpers, 17" steel wheels, manual windows and door locks, manual black side mirrors, a seven-inch touchscreen infotainment system with rearview backup camera and Apple CarPlay and Android Auto smartphone integration, vinyl seating surfaces, a split front bench seat, vinyl flooring, and air conditioning. Options include the Chrome Appearance Group (17" aluminum-alloy wheels and chrome front and rear bumpers), OnStar 4G LTE in-vehicle Wi-Fi capabilities, cloth seating surfaces, carpeted flooring with floor mats, and the Power Equipment Group (power windows and door locks, keyless entry, power black side mirrors, and cruise control).[74]

The 2020 Silverado sees deletion of the Oakwood Metallic exterior paint color. Major additions are new vertical trailering mirrors, which include power adjustability, as well as power-folding and power-extension capabilities. Adaptive Cruise control is optional on the LTZ and High Country trim levels, and SiriusXM 360L capability is available on LT and higher trims. Silverado 1500s lose the keyless access buttons on the rear doors.

The Sierra sees a new Carbon Black Metallic paint color in addition to the above-mentioned Silverado updates.

2020 is the final model year for Double Cab 1500 models in LTZ, SLT, and AT4 trims.

For 2021, the Silverado and Sierra pickups saw relatively few changes. Most notably, the Silverado 1500 offers the newly named Multi-Flex six-position tailgate, which is borrowed from the GMC Sierra, and the introduction of wireless CarPlay and Android Auto projection capability. 2.7L 4-cylinder and 3.0L Duramax diesel-equipped Silverado and Sierra models see increased tow capacity ratings and new towing technology, including a jack-knife alert and trailer length indicator. Several colors were changed on the Silverado; Havana Brown Metallic and Cajun Red Tintcoat are replaced by Oxford Brown Metallic and Cherry Red Tintcoat, respectively, and Mosaic Black Metallic is a new addition. 2021 Sierra models received color changes as well; Deep Mahogany Metallic, Red Quartz Tintcoat, and Carbon Black Metallic are replaced with Brownstone Metallic, Cayenne Red Tintcoat, and Ebony Twilight Metallic, respectively. Smokey Quartz Metallic was removed from the available color options and Hunter Metallic was added as a new paint color. For the 2021 GMC Sierra, the previously un-named "Sierra" trim becomes the "Pro".

Forward Collision Alert, Automatic Emergency Braking, and Front Pedestrian Braking options are now available on Silverado WT and Custom trim levels as part of the Safety Confidence Package. Crew Cab Standard Box Sierra 1500 models are now only available in four wheel-drive.[75]

Silverado and Sierra 3500HD dually models see an increase in max-towing capacity to 36,000 pounds.[76]

Due to the global microchip shortage, some 2021 Silverado and Sierra vehicles are built without options like Automatic Start-stop and heated and ventilated front seats, heated outboard rear seats, and heated steering wheel.[77]

The 2022 Chevy Silverado LTD and GMC Sierra Limited will enter the model lineup as a stop-gap measure until production of the newly refreshed 2022 model begins. As such, the 2022 Silverado LTD and Sierra Limited have very few changes from the 2021 models.

Notable changes for the 2022 Limited models include the deletion of both the 4.3L LV3 EcoTec3 V6 and 5.3L L82 EcoTec3 V8 with active fuel management (AFM) gasoline engines, which have been discontinued, as well as the previous "6L80" six-speed automatic transmission, leaving only eight-speed and ten-speed units. The LT Trail Boss trim-level (Chevrolet) is now available with the 3.0L Duramax Turbo-Diesel engine.[78]

For the 2022 model year, the Chevrolet Silverado 1500 and GMC Sierra 1500 receives a mid-cycle refresh that includes the following new trim levels for the Chevrolet Silverado, called the ZR2, and for the GMC Sierra, called the AT4X and Denali Ultimate. The refresh also includes a new front-end design, as well as a revised interior. All trucks equipped with front bucket seats receive a new center console-mounted transmission shift lever (trucks equipped with a front bench seat retain the previous column-mounted gear selector lever). The 3.0L Duramax turbocharged diesel Inline Six-Cylinder (I6) engine now has expanded availability on more trim levels.

The short six-foot pickup box option has returned available for the Chevrolet Silverado 1500 and GMC Sierra 1500 Regular Cabs, which was previously only available in Mexico and the Middle East and is only available with the W/T and Pro trims of the Silverado and Sierra, respectively (these trims also remain the only trims available in the Regular Cab body style). Base Silverado 1500 WT and Sierra 1500 Pro Regular Cab models now receive standard power windows, door locks and push-button start,[79] although keyless entry remains an extra-cost option. All models from the LT (Silverado)/SLE (Sierra) and above receive a newly standard 13.4-inch touchscreen infotainment system, which includes wireless Apple CarPlay and Android Auto smartphone integration and SiriusXM Satellite Radio with 360L (up-level models also receive connected GPS navigation), while base models retain the previously standard seven-inch touchscreen display. A new Silverado 1500 ZR2 model becomes the most off-road capable model in the lineup, while a new Sierra 1500 Denali Ultimate is now the top-tier trim of the lineup, which also receives a new premium Bose surround sound audio system with an amplifier, subwoofer, and genuine metal speaker grilles. Top-tier Silverado and Sierra models receive the General Motors Super Cruise semi-autonomous driving system, which allows for hands-free driving on most highways, and all models receive more standard safety equipment.

The new trim level introduced to this series as ZR2 (Chevrolet) which slots in between High Country (Chevrolet) and LTZ (Chevrolet).[80][81] GMC models receive a similar, though more upscale, model known as AT4X.[82]

The refreshed 2022 Chevrolet Silverado 1500 and GMC Sierra 1500 began shipping to dealerships in the Spring of 2022. Both brands will also sell the outgoing models of both trucks, named the Silverado 1500 LTD and Sierra 1500 Limited respectively, alongside the new models. Only 1500 (half-ton) models of both trucks have been refreshed for 2022, with a refresh of the heavy-duty (2500HD and 3500HD) trucks following at a later date.

The 2022 Silverado 1500 LTD Crew Cab was tested by the Insurance Institute for Highway Safety (IIHS):

When production of the CUCV II ended in 2000, GM redesigned it to coincide with civilian truck offerings. The CUCV nomenclature was changed to Light Service Support Vehicle (LSSV) in 2001. In 2005, LSSV production switched to AM General, a unit of MacAndrews and Forbes Holdings. The LSSV is a GM-built Chevrolet Silverado 1500, Chevrolet Silverado 2500 HD, Chevrolet Tahoe, or Chevrolet Suburban that is powered by a Duramax 6.6 liter turbo diesel engine. The various Silverados, Tahoes, and Suburbans that are used provide numerous platforms for different kinds of vehicles. As GM has redesigned its civilian trucks and SUVs from 2001–present, LSSVs have also been updated cosmetically.[93]

The Militarization of standard GM trucks/SUVs to become LSSVs includes exterior changes such as CARC paint (Forest Green, Desert Sand, or 3-color Camouflage), blackout lights, military bumpers, a brush guard, a NATO slave receptacle/NATO trailer receptacle, a pintle hook and tow shackles. The electrical system is changed to the 24/12-volt military standard. The dashboard has additional controls and data plates. The truck also can be equipped with weapon supports in the cab, cargo tie down hooks, folding troop seats, pioneer tools, winches, and other military accessories.[93]

The Enhanced Mobility Package (EMP) option adds enhanced suspension, 4-wheel anti-lock brakes, a locking differential, on/off-road beadlock tires, a tire pressure monitoring system and other upgrades. About 2,000 LSSV units were sold to U.S. and international military and law enforcement organizations.[93]

General Motors relaunched GM Defense division in 2018 offering the ZH2 Silverado, an advanced technology Chevrolet Silverado with a hydrogen powered fuel cell and a heavy-duty truck architecture modified for next generation military vehicle needs. There is also a ZH2 Chevrolet Colorado military version.
