Chevrolet Avalanche

TheChevrolet Avalancheis a four-door, five- or six-passengerpickup truckthat was manufactured byGeneral Motors.The Avalanche was a hybrid between theChevrolet SuburbanSUV and theChevrolet Silveradopickup truck, sharing the chassis with the Suburban. Unlike a typical pickup truck where the bed is mounted separately from the cab on the frame, the bed of the Avalanche was integrated with the cab body.

It also featured a "midgate" behind the second row of seats that could be folded down, with the seats, to create a longer bed area. The Avalanche was produced across two generations starting in 2001 and ending in 2013.[1][2]

Breaking with a long-standing tradition, the Avalanche was not available as a GMC, but only as aChevrolet.Instead, Cadillac would sell a re-badged Avalanche; however, the midgate design would be adapted for use on theGMC Envoy XUVandHummer H2 SUT.

The Avalanche was launched in September 2001 as a 2002 model on theGMT800platform. First year Avalanches featured light gray plastic body cladding, intended to provide visual distinction from theSuburban/Yukon XL.The Avalanche also gave the public an advance look at the next generation of front fascia designs for the entire GM line. A full-length chrome strip splits each lamp assembly and the grille, with a gold Chevrolet "bow tie" in the center. The hood and fenders featured aggressive folds, in contrast to the softer designs seen on other models built on the GMT800 platform.

Avalanche was nominated for theNorth American SUV of the Yearaward and wasMotor Trendmagazine'sTruck of the Yearfor 2002.[3]

The Avalanche was originally marketed as being able to "change from an SUV to a super SUV." This was made possible by a plastic cover and an exclusive "midgate," called the Convert-a-Cab system by GM, which could open and close. The midgate was a divider behind the second row of seats that could be folded down, with the seats, to create a longer bed area, or folded up to make a larger cab area. A similar midgate was found on the Cadillac Escalade EXT (a rebadged Avalanche), Hummer H2 SUT, and GMC Envoy XUV.[4]

Avalanche 2500 with tow mirrors

The truck was offered as a half-ton 1500 series with aVortec5.3LV8producing 285 hp (216kW) or as a three-quarter-ton 2500 series with aVortec8.1L V8 with 340 hp (253 kW) and the4L85-Efour-speed transmission. The base layout isrear-wheel drive,but there is an available with selectable high/lowfour-wheel drive.Avalanche 2500 models from 2004–2006 were exclusively available with four-wheel drive.

For those who planned to go off-road in their Avalanche, a Z71 Off-Road package was available that added features such as off-road suspension, GM's AutoTrac full-time push-button four-wheel-drive system, all-terrain P265/70R17 white-letteredGoodyeartires, seventeen-inch alloy wheels, leather seating surfaces with waterproof accents, front dual power bucket seats, cloth door panel inserts, GM's OnStar telematics system, all-weather rubber floor mats, Chevrolet bowtie emblems embedded into the backrests of the seats (for 2002 models), dual-zone automatic climate controls with rear HVAC vents and remote controls, remote radio controls with headphone jacks for two pairs of headphones, a security system, gray-finished side running boards, power-adjustable, heated side-view mirrors, SRS side impact airbags. Aside from these details, a Z71 Off-Road decal on the rear side panels identified an Avalanche equipped with this package. Full leather seating surfaces were an available option, also removing the cloth door panel inserts, and also added heated front seats.

For those who preferred the styling of the Z71 Off-Road package but did not plan to take their Avalanche off-road, a Z66 Premium On-Road package was also available. The Z66 On-Road package featured all the equipment that the Z71 Off-Road package offered but replaced the off-road suspension with sport on-road suspension and did not offer four-wheel drive. Aside from these details, a Z66 On-Road sticker on the rear side panels identified an Avalanche equipped with this package. As with the Z71 Off-Road package, full leather seating surfaces without the cloth accents were an available option, also removing the cloth door panel inserts, and also added heated front seats.

To further distinguish it from its Silverado siblings, the Avalanche was practically fully equipped and only came with bodyside cladding. The Avalanche included features such as 16-inchalloy wheelsand tires (chromed steel on the 2500 model), an AM/FM stereo with single-disc CD player and six speakers, cloth seating surfaces, front bench seat with power front driver's seat, power windows, power door locks,keyless entry,full instrumentation, dual frontairbags,andair conditioning.Options includedOnStartelematicssystem,cassette player,leatherseating surfaces, front dual power bucket seats that could be heated, and sideairbagsfor the front seats. ANorth FaceEdition, in partnership with the North Face brand included limited exterior color options, a unique Ebony/Greenleatherinterior, special exterior ornamentation and decals, white-faced gauges,OnStartelematicssystem, specially colored door panel inserts and speaker grilles, and more.

Avalanche WBH (Without Body Hardware)

For 2003, the Avalanche was slightly changed. 2003 models featured a darker cladding, but GM's new president,Rick Wagoner,demanded the removal of this "unpopular" trim (as did certain elements of the public). From mid-year, Avalanche could be ordered without cladding. The uncladded model, known as "Without Body Hardware" (or its initialism "WBH," which is also anRPO code), and alternatively called "slicksides" by GM marketers, resembled the 2003–2005Silverado1500 in the front. A new interior—shared with theTahoeandSuburban—added a new, larger steering wheel with subsequent audio, cruise, and speed controls; an optional six-speaker premiumBosesound system with externalamplifier;a new gauge cluster with information center and memory for the front driver's seat, brake and accelerator pedals, and side-view mirror position (on some models); new radiohead units,which included an AM/FM stereo with either a single-disc or six-disc CD/MP3 changer,Radio Data System,and optionalXM Satellite Radio;standardOnStartelematicssystem with steering wheel controls; new warning chimes that played through the vehicle's audio system instead of through a separate speaker behind the dashboard; and newly available 17-inchalloy wheelsand tires. Optional features included rear audio controls withheadphonejacks and a rearDVDentertainment system byPanasonicwith wireless headphones. The WBH option was only available in the 1500 series.

Avalanche Base Camp Concept (1999)

edit

A pre-production version of the Avalanche was shown as the Avalanche Base Camp Concept. The truck, which carried theVehicle Identification Number(VIN) of1GCFK13U32X4618EX,was painted inBright Yellow Clear Coat,and featured aNeutralcloth interior with contrasting yellow trim on the seats andChevroletBowtie emblems on the seatbacks, speaker grilles, and door panels, as well asCadillac Escalade–style wood trim on the instrument panel. The truck was powered by the 6.0L Vortec V8 gasoline engine, which was not offered on the production Avalanche. In addition, the Avalanche Base Camp Concept featured unique accessories that were not available on the production truck, such as aBosepremium audio system, which included a bass module (subwoofer) and bedside-mounted speakers; a unique roof rack; a rearDVDentertainment system with threeLCDmonitors; dualNokia5125cellular phoneswith color-coordinated yellow faceplates; a "keyless" ignition system that included a push-button to start; a battery cutoff switch (for show purposes); a trailer hitch-mountedcooler;a unique front brush guard and side running boards; a bed painted to match the interior of the vehicle; a Diamond-Plate tailgate liner; a bed-mountedLCDscreen; "Avalanche Base Camp" em Boss ing on the body side cladding; and a mobile cooking stove and sink, among other accessories. The vehicle was sold at the 2006Barrett-Jacksoncollector carauctioninPalm Beach, Florida,for $20,900 (equivalent to $31,588 in 2023).[5]It was later listed with 2,000 miles on the Cars & Bids onlineauctionwebsite in July 2023.[6]

Cladding issues

edit

Soon after the release of the Chevrolet Avalanche, customers began to notice cosmetic issues with thecladdingon their vehicles. Over time, exposure to heat and sunlight would cause a chalky faded appearance. It was especially noticeable on the cargo bed panels, and sail-panel windows where "zebra striping" would appear. Customer reaction to this problem resulted in General Motors agreeing to a one-time treatment of a product called ArmorDillo. This product would temporarily restore the cladding for a period of about six months; thereafter, it would wear off and need to be re-applied. Realizing this was not a permanent solution, GM, together with Gatorback Coatings, developed a coating that could be applied to the cladding to restore it to a like-new shine. This product was designed to etch into the plastic and bond a new layer of tinted acrylic over the faded plastic. Customers within the original factory warranty could go to their dealership to have it restored. General Motors did not use side body cladding on the second-generation model.

The second generation Avalanche was introduced at theChicago Auto Showin February 2006. Production of the redesigned Avalanche, built on theGMT900platform, began at the Silao Assembly plant in April 2006. The Avalanche maintained the styled front end much like its sister vehicles, theTahoe/Yukonand Suburban/Yukon XL, yet it still had the distinct midgate and integrated bed as found on the previous incarnation. It had all the same standard and available features as the Suburban and the Tahoe. The 2500 model of the previous generation was discontinued.

A special Z71 package was offered for the second-generation Avalanche, available on the LT trim with either the 2LT or 3LT option groups. This off-road package consisted of a suspension tuned for rough terrain, an exclusive automatic-locking rear differential, aluminum under-body skid plates (visible from the front of the truck), wheel flares, badges, wheels, and tires.

For the first time, the steering system was switched from the traditional recirculating-ball to a rack-and-pinion also found in the Tahoe and Suburban 1500. Later models introduced another version of the Vortec 5.3-liter V8 as the engine is now capable of running on E85 ethanol. On normal gasoline, it produces 320 hp (239 kW) and 335 lb⋅ft (454 N⋅m) of torque, whereas on E85, its output rises to 326 hp (243 kW) and 348 lb⋅ft (472 N⋅m) of torque, up from 310 hp (231 kW) and 335 lb⋅ft (454 N⋅m) in 2009.

A 2007 Avalanche was given away to the Most Valuable Player of the2006Major League Baseball All-Star Game,Michael Young.

For the 2009model year,aBluetoothhands-free phone system was added to all Avalanche models, and was integrated with the vehicle'sOnStartelematicssystem, and the 4L60-E four-speedautomatic transmissionwas replaced with the 6L80-E unit for both engines.

Following the 2009model year,the 6.0L V8 engine option was dropped from the Avalanche lineup (in addition to being discontinued from the relatedChevrolet Suburban1500 andChevrolet Tahoe), leaving the standard 5.3L V8 as the Avalanche's sole engine option.
