The Jeep Grand Cherokee is a mid-size UniFrame sport utility vehicle produced by the Jeep division of Chrysler. European Grand Cherokees are manufactured in Austria by Magna Steyr.[2]



The Grand Cherokee's origins date back to 1983 when American Motors (AMC) engineers were designing a successor to the smaller Jeep Cherokee (XJ).[3] 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.[4] 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.[5]

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, CEO Lee Iacocca was pushing for redesigned Chrysler minivans, 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.

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 forever. 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 300 lb·ft (410 N·m) 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 dating back to 1974 were replaced with the typeface used on other Chrysler vehicles. The AMC 4.0 L straight-6 engine, able to tow 5,000 lb (2,300 kg), was also refined, through minimal loss in power 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).


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 optional on all models.


An available "Up Country" package was offered. The suspension package included heavier duty German made gas charged shocks installed upside down, taller coil springs and longer bump stops


The Grand Cherokee V8 was on Car and Driver magazine's Ten Best list 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).

Special edition ZJs

1993 Jeep Grand Wagoneer

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.

Jeep Grand Wagoneer (1993)

For 1993 alone, Jeep carried over the Grand Wagoneer name for a special luxury version of the Grand Cherokee with both the 4.0L I6 and the 5.2 L V8 engines, 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, and 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)

1996 Grand Cherokee Orvis

The Orvis (1995–1997)[7] was a Grand Cherokee Limited package that featured an exterior color scheme of Moss Green, or in 1997 the (less common) Light Driftwood, with roan red and maize side strip accents (1995). Moss Green paint accents on the road wheels (matching the moss 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 complemented with roan red accent piping and Orvis insignia. There was a slight difference between the 1996 and 1997 years' interior compared to each other. The 1996 had a black dash where the 1997 had a tan dash, The Orvis Edition luxury trim package was optional on the Limited version, and when equipped with all the other options was 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)

1998 Grand Cherokee TSi

A sporty TSi model (1997–1999) briefly debuted, exterior features included single color body paneling, with lower indigo blue striping and TSi, accent similar to that found on the Eagle Talon model. TSi packages came equipped with 5 spoke 16-inch (410 mm) alloy wheels, 225/70R16 tires, sport tuned suspension and steering, perforated leather seats, and a premium sound system. The 4.0 litre I6 and the 5.2 litre V8 were the only two available engines in this package. The TSi was priced between the Laredo and the Limited.

The 5.9 L Limited ZJ (1998)

The 5.9 Limited was a Jeep Grand Cherokee produced only for the 1998 model year, having more luxury and performance than that of the regular Limited. Chrysler manufactured nearly a quarter million Grand Cherokees in 1998. Of those, less than fifteen thousand were 5.9s. It housed a Magnum 5.9 LV8 engine with an output of 245 hp (183 kW) and 345 lb·ft (468 N·m) of torque, going from zero to 60 mph (100 km/h)in only 7.3 seconds[8] (Motor Trend measured this at a slightly faster 6.8 seconds[9]), making it the quickest SUV available that year. The performance of the 1998 5.9 L V8 has been surpassed by Jeep only with the introduction of the 2006 Jeep Grand Cherokee SRT8, which housed a 6.1 L Hemi Engine.[10] The 5.9 Jeep Grand Cherokee was named the 1998 four-wheel drive vehicle of the year by Petersen's 4-Wheel & Off-Road Magazine.[11]

The 5.9 Limited was available only in Deep Slate, Stone White, and Bright Platinum. Other features separated the 5.9 from the standard Limited model including:[12]

A Deep Slate 1998 Grand Cherokee 5.9 L (Note hood louvers and mesh grille inserts)
  • Functioning heat-extracting hood louvers
  • Mesh grille insert
  • Five-spoke alloy Ultrastar wheels
  • Black-wall tires
  • An improved premium 180 watt, 10 speaker Infinity stereo system
  • A rear speaker bar for additional Infinity speakers
  • Calf-grain, soft leather seats and trim
  • Leather door inserts
  • Leather shift handle, e-brake and transfer case handle
  • Enhanced faux wood trim throughout, additionally 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 5.2 L limited
  • Molded rocker panels

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

  • A stronger 46RE transmission than the 5.2
  • Quadratrac heavy duty NV249 transfer case
  • Standard trac-lock rear differential
  • An electric fan
  • A high-output 150A alternator
  • Lower restriction exhaust and chrome plated exhaust tip[13]

The redesigned WJ 1999 Grand Cherokee shared just 127 parts with its predecessor. . 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 1960s (SOHC aluminium heads, plastic intake), Chrysler's then-new PowerTech. 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 23 gallon fuel tank was replaced with one of a 20.5 gallon capacity). The Inline 6 engine was also updated in 1999. 10 horsepower (7.5 kW) was added by redesigning the intake manifold.

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 Ramcharger SUVs in 1986.

A notable feature available in this generation was the automatic four wheel drive option called Quadra-Drive, which employed the New Venture Gear NV247 transfer case. This two-speed chain-driven transfer case uses a gerotor, a clutch pack coupled to a hydraulic pump, to transfer torque between the front and rear axles. The transfer case contains three modes, 4-All Time, Neutral, and 4-Lo. In 4-All Time, 100% of torque is sent to the rear axle in normal conditions. If the rear axle starts spinning at a higher rate than the front axle, hydraulic pressure builds up in the gerotor and causes the clutch pack to progressively transfer torque to the front axle until both axles return to the same speed. Neutral mode is intended for towing the vehicle. In 4-Lo, the front and rear axles are locked together through a 2.72 reduction gear ratio. The NV247 transfer case is mated to front and rear axles containing Jeep's Vari-Lok differentials. Vari-Lok differentials also use a gerotor to transfer torque. 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 45RFE and 545RFE 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 (110 km/h) 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.

In addition to Jeep's UniFrame construction, Daimler Chrysler partnered with Porsche to further strengthen the frame.[citation needed] This was done to reduce NVH and improve off-road performance. UniFrame is an unusual construction scheme, it incorporates all of the strength and durability of a body-on-frame construction into a unitized construction. By adding stiffness and rigidity to the structure, they enhanced the ride and strengthened the network of steel beams, rails and pillars (or "safety cage") that surround and protect occupants. More than 70 percent of the underbody is high-strength steel. All Jeep Grand Cherokees feature UniFrame construction.

The Grand Cherokee received a minor facelift for 2004 including round fog lamps, a lower front fascia and a new body-color matched inset grille design.

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, priced between the Laredo and Limited, offering the same quality of the Limited, differences include the option of the 4.7 L V8 engine. Special Edition came with premium interior details (Instrument cluster graphics were shared with Laredo model, did not acquire white-faced gauges from Limited model), 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 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 Limited the 4.7 L High Output engine V8 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-inch 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. The Freedom Edition was a modified Laredo model. Features include special badging, painted charcoal rock rails, painted charcoal lower-body cladding (essentially Limited type smooth cladding, Laredos used a textured grey cladding), painted charcoal front and rear fascias (again, similar to Limited), charcoal painted wheels, silver interior accents, and optional leather seats.

Chinese production

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.[16]

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 V8. The 3.7L V6 engine replaced the 4.0L Straight-6.

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 Liberty. 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.

2008 Jeep Grand Cherokee

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 4.7L was refined, now producing 305 horsepower, and 334 lb·ft (453 N·m).

The 2009 Jeep Grand Cherokee is available with an improved 5.7-liter HEMI rated at 357 horsepower (266 kW) and 389 ft·lbf (527 N·m). (527 N•m) of torque. The engine uses variable valve timing to increase fuel economy.[20]

-The 4.7 L High Output engine that first appeared with the Grand Cherokee Overland WJ was dropped from the current Jeep lineup. It is now used exclusively in the Dodge Dakota. The 4.7L was revised in 2008, increasing horsepower and torque. A dedicated High Output version was dropped as a result.

-The WK is known as a WH in International (i.e. non-US) markets

-The 5.7L HEMI engine for 2005-2008 has slghtly less horsepower than those found in the Dodge Ram or the Dodge Charger (330 vs 345) due to different ECM progamming.

-The 5.7L HEMI engine for 2009 and up was upgraded with Variable Cam Timing (VCT) adding 27 horsepower and 14 lb·ft (19 N·m) of torque

-The 3.0L diesel ceased production for North America at the end of 2008. The late production models with diesel engines are commonly referred to as 2008.5 models. They can not be stamped as 2009 models due to tougher diesel emissions standards.

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 420 hp (313 kW) version of the 6.1 L Hemi, 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 11.2" (285 mm) wide Goodyear tires in the rear (10" or 255 mm in the front) complement the performance package. The sports tuned suspension allows the Jeep SRT8 to hold 0.92g on the skid-pad, putting the 5,000 lb (2,300 kg) truck on par with the Porsche 911 Turbo (997), which holds just 0.04g more (0.96g) on the skid-pad. A road test of the 2006 model by Road & Track magazine yielded a 0 to 60 mph time of 4.6 seconds and a quarter mile dragstrip of 13.2 seconds at 104.1 miles per hour (167.5 km/h). Such numbers made the SRT-8 Grand Cherokee the fastest accelerating vehicle within the SRT8 lineup (which at the time included the Chrysler 300C, Dodge Charger, Dodge Challenger and the now-discontinued Dodge Magnum), and second only to the SRT10 Viper among all SRT tuned 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 (270 km/h).[21]

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 7 inches (178 mm) of ground clearance. The Grand Cherokee SRT-8 was the first SRT vehicle to wear the Jeep emblem.

Only 10,355 Jeep SRT8s have been built to date.


2008 Grand Cherokee with 3.0 V6 Turbo Diesel

In Europe, South America, South Africa 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 218 horsepower (163 kW; 221 PS) and 376 lb·ft (510 N·m) of torque at 1,600 to 2,800 rpm.

In North America and elsewhere this 3.0 L V6 CRD was available for 2007-2008 model years. It includes a diesel particulate filter to reduce exhaust emissions. It was not however available for sale in California or certain Northeast states, due to new stricter emissions regulations for non-commercial vehicles. Vehicles could be bought used in California and Northeast states, as the regulations only applied to new vehicles.

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