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

Grand cherokee Development
The Grand Cherokee's origins date back to 1983 when American Motors (AMC) engineers were designing a successor to the smaller Jeep Cherokee (XJ).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, 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.

Grand Cherokee ZJ (1993–1998)
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).

Grand Cherokee 4x4 (Four-wheel drive systems)
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.

Grand Cherokee Suspension
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 Awards
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)
