The Jeep Grand Cherokee is a mid-size unibody sport utility vehicle produced by the Jeep division of Chrysler. European Grand Cherokees are manufactured in Austria by Magna Steyr.

Development Edit

The Grand Cherokee's origins date back to 1983 when American Motors (AMC) engineers were designing a successor to the smaller Jeep. Three outside (non-AMC) designers — Larry Shinoda, Adam Clenet, and Giorgetto Giugiaro — were under contract with AMC to create and build a clay model of the replacement model, then known as the "XJC" project. However, the basic design for the Cherokee's replacement was well under way by AMC's in-house designers and the 1989 Jeep Concept 1 show car foretold the basic design.

The Grand Cherokee was the first Chrysler-badged Jeep product. Development work for the new model continued and Chrysler employees (after the 1987 buyout of AMC) were eager for a late-1980s release date; however, then-CEO Lee Iacocca was pushing for redesigned Chrysler, thus delaying the Grand Cherokee's release until late 1992 as an Explorer competitor.

The Grand Cherokee debuted in grand fashion at the 1992 North American International Auto Show in Detroit, Michigan. Then-Chrysler president Robert Lutz drove Detroit mayor, Coleman Young up the steps of Cobo Hall and through a plate glass window to show off the new vehicle. Production of the Grand Cherokee started shortly afterward in the purpose-built Jefferson North Assembly in Detroit, Michigan and has remained there since.

ZJ (1993–1998) Edit

File:1993 Grand Cherokee front.jpg
The ZJ models, manufactured from 1993 to 1998, originally came in three general trims, the Base, Laredo, and the Limited. The Base model offered basic features such as full instruments, cloth interior, a standard five-speed manual transmission, while soon gaining the moniker SE name in 1994. Creature comforts like power windows and locks were not standard equipment on the SE, although conveniences like these were finally included in 1995; a somewhat contrasting pricetag with minimal production numbers resulted with low consumer demand and dropping the now-uncommon bare-bone model indefinitely. The Laredo was the mid-scale model (essentially becoming base model after 1996), standard features included added body cladding power windows, power door locks, and cruise control; exterior features displayed a medium grey plastic lower body paneling and five-spoke Aluminum wheels. The Limited was the premium model, with the lower body paneling being the same color as the vehicle color. The Limited also boasted standard features such as leather seating, optional power sunroof, mirrors, seats, and remote keyless entry system; heated mirrors, and heated seats, a basic onboard Computer; and waffle-like cast aluminum wheels.

In 1995 the performance of the V8 engine was upgraded to from 285 previously. 1996 brought cosmetic changes ranging from improved body modeling (Grille, bumpers), and integrated foglights; interior features added dual airbags and increased fabric quality for seating. At the same time, the "Grand Cherokee" fender emblems in the American Motors-typeface were replaced with the typeface used on other Chrysler vehicles. The AMC 4.0 L straight-6 engine, able to tow 5,000 lb, was also refined, through minimal loss in horsepower but gained more torque and presented quieter operation. Limited models that year and onward had more luxury items such as driver placement memory, remote radio control from the steering wheel, and variable assist while driving and parking.

Between 1996-98, the export Grand Cherokee Laredo (marketed for Japan) had the optional Aspen package (source: The Story of Jeep).

Special edition ZJs Edit

Throughout its lifetime, there were several different "one-off" and special edition models of the ZJ, including but not limited to the gold series. The following highlights several of these.

The 5.9L Limited ZJ (1998) Edit


The Grand Cherokee 5.9-Liter Limited was produced in limited numbers only for the 1998 model year, having more luxury and performance than that of the regular Limited and sold under the trim '5.9 Limited'. A similar trim was introduced in Europe under 'LX' trims (not 5.9L). There are only 15000 worldwide. Although it is not very expensive in North America, it is significantly pricer in the Middle East and Asia because of the low quantity. It housed a Magnum 5.9 L V8 engine displacing 360 cubic inches with an output of and of torque, going from zero to in only 7.3 seconds (Motor Trend measured this at a significantly faster 6.8 seconds see Motor Trend, January 1998, page 51.), making it the quickest SUV available that year. The straight-line performance of the 1998 Grand Cherokee 5.9 has been surpassed by Jeep only with the 2006 introduction of the 6.1 L SRT8 HEMI Grand Cherokee. The 1998 Grand Cherokee was Motor Trend's 4x4 of the year in 1998. Their rarity and performance make them highly sought after (see, e.g. the Grand Cherokee Forum on and, as well as the Speed Freaks Forum on

Other features separated the 5.9 from the standard Limited model including:

  • functioning heat-extracting hood louvers
  • a mesh grille insert
  • unique five-spoke Alloy wheels
  • black-wall tires
  • an improved premium 180 watt, 10 speaker infinity stereo system,
  • a rear speaker bar, roof mounted with 4 speakers in 2 locations
  • softer calf leather trim,
  • leather door inserts,
  • leather shift handle, e-brake and transfer case handle,
  • wood trim around the transmission shift handle base
  • a full-leather spare tire cover with multiple pockets
  • a center leather armrest in the rear seat
  • a lower-profile roof rack that eliminated squeaking problems found on the base 5.2L limited
  • monochromatic trim
  • molded rocker panels

The Grand Cherokee 5.9 further included additional performance-enhancing features including:

  • stronger transmission than the 5.2L with a heavier output shaft
  • standard Dana-44A(ALUM. HOUSING) rear differential with traction lock
  • electric fan
  • high-output alternator
  • freer-flowing exhaust with 3 inch pipes and a wide polished stainless steel exhaust tip

The 5.9 Limited was not available in all the regular Limited colors. It was available only in Deep Slate, Stone White, and Bright Platinum.

Jeep Grand Wagoneer (1993) Edit


1993 Jeep Grand Wagoneer

For 1993 alone, Jeep carried over the Jeep name for a special luxury version of the Grand Cherokee with the 5.2 L V8, this marked the last appearance for the Grand Wagoneer in the Jeep lineup. Having all the features of the Limited, it featured a simulated wood grain body cladding, along with special Grand Wagoneer badging, aqnd a unique leather interior. This Jeep was the most costly of the line up, and was produced in limited numbers.

The Orvis Edition (1995-1997) Edit

File:Orvis 004.jpg

The Orvis (1995-1997) was a Grand Cherokee Limited package that featured an exterior color scheme of either Deep Hunter Green, or (less commonly) Light Driftwood, with red and gold side strip accents (1995). Green paint accents on the road wheels (matching the deep hunter green body color) and the special "Orvis" brand badging were the only significant exterior visual differences. In performance, the 5.2 V8 engine became standard, but was available with a 4.0 inline 6 cylinder engine. Also, all Orvis editions were installed with tow hooks and the Up-Country suspension group. However, the interior was special. Two-tone green and tan leather seats were complimented with red accent piping and Orvis insignia. Because it was an additional luxury trim package to the Limited, the Orvis Edition (when fully optioned) became the most expensive of all the Grand Cherokee versions until 1998 when the 5.9 Limited was introduced.

Production numbers of the Orvis Editions are:
1995- 10,020
1996- 2,341
1997- 2,733

TSi (1997-1998) Edit

A sporty TSi model (1997-1998) briefly debuted, exterior features included single color body paneling, with lower indigo blue striping accent similar to that found on the Eagle Talon model. TSi packages came equipped with 5 spoke 16-inch alloy wheels, 225/70R16 tires, sport tuned suspension and steering, perforated leather seats, and a premium sound system. A 5.2 litre V8 was available. The TSi was priced between the Laredo and the Limited.

4x4 Edit

Four-wheel drive systems included Command-Trac, a part-time unit offering temporary 4-wheel assistance; Command-Trac was dropped from lineup in conjunction with the SE trim in 1996. Selec-Trac had the option of either full-time or part-time operation; both shift-on-the-fly Command-Trac and Selec-Trac were already available for the Cherokee, and they were adapted to the Grand Cherokee. Exclusive to the Grand Cherokee was the introduction of Quadra-Trac system with permanent all-time four-wheel assistance. This was standard on all Limited and most specialty trims, as well as optional on Laredo models. Rear wheel drive I6 models were sold though only for the Laredo in late 1993, while it was in 1994 when rear wheel drive was made available for the Limited. In 1997, the 5.2 L V8 engines were made optional in rear wheel drive models.

Suspension Edit

An available "Up Country" package was offered. The suspension package included heavier duty gas charged shocks, along with various other suspension components improved.

Awards Edit

The Grand Cherokee V8 was on Car and Driver magazine's Car and Driver and was Motor Trend magazine's Truck of the Year for 1993.

It was also Petersen's 4x4 of the Year in 1993, 1996 (with the redesigned NV249 transfer case), 1998 (with the newly available 5.9L V-8), 1999 (with its acclaimed 2nd generation model), 2001 (with the new 5-speed transmission), and 2005 (with its 3rd generation model).

WJ (1999–2004) Edit

The redesigned WJ 1999 Grand Cherokee shared just 127 parts with its predecessor. The structure was stiffened by Porsche Engineering for sharper steering and lighter weight. The spare tire was relocated from the side of the cargo compartment to under the floor to great relief of owners. The two heavy pushrod V8 engines were replaced by chrysler's first clean sheet V8 since the 60's (SOHC aluminium heads, plastic intake), Chrysler's then-new Chrysler. Although this engine produced less torque than both previous V8s, it was lighter and got much better fuel economy and provided similar on road performance figures. The Inline 6 engine was also updated in 1999. 10 Horsepower was added by redesigning the intake manifold. The manual transmission was dropped with this model.

While other Jeep vehicles used the Mopar 5 x 4.5 bolt circle, this was the first Jeep following the 1987 Chrysler buyout to receive a wider bolt pattern — 5 x 5. The 5 x 5 bolt pattern (also 5 x 127 mm), although common to GM rear wheel drive vehicles and light duty trucks/vans, has spread beyond its use with GM (and Ford with their 1973 to 1978 LTDs and Lincolns). Chrysler first used the 5 x 5 pattern on full-size half-ton Dodge Ram pickups and Dodge Ram SUVs in 1986.

A notable feature that was available this generation was the automatic four wheel drive option called Quadra-Drive. With three viscous clutches, it was one of only a few four wheel drive systems at the time with triple locking differentals, joining the contemporary Mercedes Gelandewagen, Mercedes Unimog and Magna Steyr Pinzgauer, and the only one of the four with fully automatic operation, although the axle differentials could not be manually locked like in the other three vehicles.

The Chrysler and Chrysler Automatic transmission in the WJ was notable. It included three planetary gear sets rather than the two normally used in a four-speed automatic. This gave it six theoretical speeds, and it would have been the first six-speed transmission ever produced in volume, but it was programmed to only use five of these ratios. Four were used for upshifts, with a different second gear for downshifts. Although five of the six ratios were used, Chrysler decided to call it a "4-speed automatic". In 2001, the programming was changed to make use of all six ratios. Rather than have six forward gears, the transmission was programmed to act as a five-speed with the alternate second gear for downshifts. The RPM at 70 miles per hour on a 545RFE is 2000 RPM, 200 RPM less than the 45RFE programming. 1999 and 2000 model year WJ owners can have their 45RFE transmission's programming flashed to enable the extra gear as both transmissions are physically the same. The 42RE 4-speed automatic remained the transmission for the Inline 6 engine. It was not changed from the previous model Grand Cherokee's.

The interior was also completely redesigned in 1999. The redesign allowed for larger rear doors, and more space for rear passengers. Controls for various items like headlights, heated seats, and rear wiper were moved to more convenient locations. The electronic Vehicle Information center was moved from below the radio to above the windshield, and was standard on all 2000 and up models. Limited models included automatic dual-zone climate control. A 10 CD-Changer was also available with the Infinity Audio package.

The Grand Cherokee received a minor facelift for 2004.


Models Edit

The Laredo and luxurious Limited trim levels were standard models.

Specialty models:

These specialty models appeared for a brief time, The Sport was slightly more equipped than the Laredo and offered a very discrete two-tone black trim interior for style. The Special Edition was introduced offering the same quality of the Limited, differences include 4.7 L V8 engine and slightly revised, Special Edition came with premium interior details, Plush Leather seats, AM-FM, In-Dash CD/Cassette along with ten disc CD changer stowed in a well thought location in within cargo space. Special Edition Trim package from bumper to bumper was presented with a fully polished, non-textured finish. Front grille debut was standard issue on the Special Edition. The Overland (appropriated after the former Jeep parent, Willys-Overland) was the top-of-the-line alongside the Special Edition the Chrysler engine V8 initially debuted as the standard motor. Alongside a wealth of standard features such as plusher interior trim with "Overland" badging, mid-2003 came a revised strong black two-tone trim interior and Built-in GPS equipped with the model. Front and side-curtain Airbags, an Infinity sound system with 10-disc changer, heated/power front seats, integrated rock rails, power sunroof, wood/leather steering wheel and 17 in alloy wheels were also standard. The Columbia Edition offered the usual features of the other specialty models besides a strong unique two-tone interior with "Columbia Sportswear" badging, with the 4.7 L H.O. engine and GPS optional.

Chinese Production Edit

Beijing Jeep Corporation, Ltd. had been producing the XJ classic Cherokee since 1984, and in 2004 they bought the old tooling for the WJ Grand Cherokee when the WK was introduced for the USA as a 2005 model. After some tooling up time, the WJ was introduced in 2006 for the Chinese market as the Jeep 4000 and 4700 Grand Cherokee (for the 4.0 I-6 and 4.7 V8, inc. HO, models respectively).

It was their flagship model and nearly identical to the 2004 Grand Cherokee Limited in looks and equipment, including the solid axle suspension, choice of 4wd systems, body color cladding, alloy wheels, Chrysler sound systems, and Chrysler automatic climate controls. This is unlike the XJ Cherokee that was significantly modified by Beijing Jeep for the Chinese market.

The current model is now sold in China.

Detroit Diesel/VM MotoriEdit

The 3.1 litre turbo-diesel on the 1999 Grand Cherokee was developed in conjunction with Detroit Diesel/VM Motori. It has an electronic injection pump, electronically-controlled, vacuum-actuated exhaust gas recirculation, and a special catalyst to control oxides of nitrogen (NOx). Manufactured in Cento, Italy, at 13,000 units per year. It was available in European models and meets the European stage III emissions.

  • Displacement: 3124 cc (191 CID
  • Power: 104 kW/140 bhp
  • Torque: 367 Nm/271 ft·lbf
  • Transmission: Four speed electronically controlled automatic

WK (2005–2009) Edit

The all-new WK Grand Cherokee debuted in 2004 for the 2005 model year. Features available for the first time in a Jeep included Quadra-Drive II four-wheel drive, rear-seat DVD player and optional 5.7L Hemi V-8.

The design still emphasizes power and luxury, with significant work done on improving noise, vibration, and harshness (NVH). However, for the first time, Jeep also emphasized on-road performance to a similar extent as the cornerstone of its brand, off-road capability.

This newfound emphasis on on-road refinement led Jeep to replace the live-axle with leading-arms front suspension (found in the ZJ and WJ) with a new design: an independent double-wishbone setup like that which debuted in the 2002 Jeep. The new Jeep changed its philosophy due to what it perceived as increasing demand in the SUV marketplace for on-road performance and decreasing demand for off-road capability, and though the new design is perceived to be more smooth over washboard-types of roads, the new front suspension was criticized by off-roading Jeep community for its inability to provide optimal axle articulation during low-speed, technical maneuvers, specifically over uneven terrain.

The 2007 Jeep Grand Cherokee made its European debut at the Euro Camp Jeep held in Ardèche, France.

File:2008 Jeep Grand Cherokee.jpg

The Grand Cherokee received a minor facelift for 2008. The bottom part of the headlights became rounded, and the lower portion of the front bumper became removable to increase the approach angle for off-road use.

The 2009 Jeep Grand Cherokee is available with an improved 5.7-liter HEMI rated at 357 Horsepower (266 kW) and 389 lb.-ft. (527 N•m) of torque. The engine uses variable valve timing to increase fuel economy.

Notes Edit

The 4.7 L High Output engine that first appeared with the Grand Cherokee Overland Jeep was dropped from the current Jeep lineup. It is now used exclusively in the Dodge Dakota. The WK is known as a WH in International (i.e. non-US) markets

SRT-8 Edit

File:Jeep Grand Cherokee SRT8.jpg

An SRT-8 (Street and Racing Technology V8) version of the Grand Cherokee debuted at the 2005 New York International Auto Show. Powered by a version of the 6.1 L Chrysler, it also features upgraded Brembo brakes, large dual performance exhaust with polished tips (exiting out the middle of the rear), Bilstein performance gas charged shocks and modified suspension components, Mercedes-Benz NAG1 (WA580) 5-speed transmission, unique NV146 transfer case, specially designed electronic all-wheel-drive system and interior and exterior updates. A drive shaft from a diesel application, fortified Dana 44 rear differential, and 12" wide Goodyear tires in the rear (11" in the front) complement the performance package. It has a base MSRP of $40,230 USD. A road test of the 2006 model by Road & Track magazine proved that the stock SRT8 is "focused 100 percent on performance; road performance, that is” with "sports car" performance numbers, including 0 to 60 mph in 4.6 seconds and to the quarter mile Dragstrip in 13.2 seconds at . Such numbers made the SRT-8 Grand Cherokee the fastest accelerating vehicle within the SRT8 lineup (which at the time included the Dodge Magnum, Dodge Charger, and Chrysler), and second only to the Viper among all Daimler-Chrysler SRT vehicles. There is no electronic speed governor employed, leaving the top speed rev-limited (revving to redline in top gear) to just shy of 170 MPH.

To achieve superior on-road handling, off-road gear has been removed to make the SRT-8 lighter. The SRT-8 has no low range case and no limited slip or locking differentials. Its ride stance is significantly lower and the front fascia spoiler gives the vehicle of ground clearance. The Grand Cherokee SRT-8 was the first SRT vehicle to wear the Jeep emblem.

The 2009 Jeep Grand Cherokee SRT8 is equipped with a reconfigurable display that displays performance information including longitudinal and lateral g-force, 0-60 mph acceleration time, 1/8-mile and 1/4-mile acceleration time, and speed and braking distance.

Hennessey SRT600 Edit

The Jeep SRT8 upgrade by Hennessey Performance Engineering (HPE) out-accelerates a stock Dodge Viper by more than a car length at 60 mph (0-to-60 mph in 3.4 seconds, 1.4 seconds quicker than stock) and beats the SRT10 Viper in the quarter mile. With a turbocharged 6.1 L Hemi V8 inside, the exterior modifications consist of a few SRT600 badges and optional 20x10.5-inch forged-aluminum wheels wrapped in grippy Michelin Pilot Sport 2 295/30ZR20 tires.

Diesel Edit

File:2008 Jeep Grand Cherokee 3.0 Diesel engine.JPG

In Europe, South America and Australia, a V6 CRD engine was available from introduction in 2005:

OM642 3.0 L CRD V6 Turbo Diesel with Variable geometry turbocharger (VGT). It produces and of torque at 1,600 to 2,800 RPM.

In North America and elsewhere this BlueTec 3.0 L V6 CRD became available since 2007. It includes a diesel particulate filter to reduce exhaust emissions.

This engine is also used in the Mercedes-Benz ML320.

Next-generation (2010– ) Edit

The next-generation Jeep Grand Cherokee will be in 2010 with a unibody construction and a fuel-efficient V6 engine that is being developed under the codename Phoenix. The company announced a $1.8 billion, expansion of its Jefferson North Assembly plant to allow flexible manufacture of the next-generation model, as well as other undisclosed products off the same platform that was developed jointly with Mercedes.[1]
