A small SUV produced by Jeep. Launched in 1986 as a model year 1987 vehicle, it replaced the Jeep CJ-7 and while not intended to be a military vehicle it is the modern descendant of the World War II Willys MB Jeep.

A Jeep Wrangler appears in the background of the cover of the 2016 book Lake Destiny by C.F. Walko.

History

The following section is an excerpt from Wikipedia's Jeep Wrangler page on 1 January 2017, text available via the Creative Commons Attribution-ShareAlike 3.0 Unported License.

The Jeep Wrangler is a compact and mid-size (Wrangler Unlimited models) four-wheel drive off-road vehicle manufactured by Jeep, currently in its third generation.

The Wrangler is arguably an indirect progression from the World War II Willys MB through the Willys civilian Jeeps (Jeep CJ) of the mid-1940s through 1980s that were produced by Kaiser-Jeep and by American Motors Corporation (AMC). Neither AMC nor Chrysler (after it purchased AMC in 1987) have claimed that the Wrangler was a direct descendant of the original military model.

Outwardly resembling the Jeep CJ-7, the Wrangler, which was formally announced in February 1986 at the 1986 Chicago Auto Show, was based on a new set of design parameters. "The product philosophy behind the two vehicles" François Castaing (AMC VP of Product Engineering) explained, "is completely different". Just like the Willys MB and the Jeep CJ, Wranglers continue to use a separate body and frame, rigid solid axles both front and rear, a fold-flat windshield, and can be driven without doors. But its suspension, drivetrain, and interior were borrowed from the new Cherokee (XJ) model.

The Wrangler debuted in 1986 as a new model after discontinuance of the famous Jeep model (CJ). It was revised in 1996, and completely redesigned in 2006. In addition to the model name Wrangler, each model received a designation corresponding to its generation: YJ (1986–1995), TJ (1997–2006), TJU's (commonly known as LJs- 2004–2006 Unlimited models, or YJL, in the Egyptian owners manual.), JKU (2007–present Unlimited models) and JK (2007–present). Foreign military versions of the Wrangler have carried the J8 designation which was initially dubbed TJL when first produced at Arab American Vehicle's Egyptian plant.

Jeep YJ models were manufactured between 1986 and 1995 at Brampton Assembly, and subsequently at the Toledo South Assembly plant. A major difference in the 1987–1995 models were the rectangular headlights, which reverted to rounded ones in the TJ and then JK versions. In 2006, Wrangler production was moved to Toledo Complex. Post-2006 Wranglers were set apart from their predecessors by the angle of the grille. In all previous models, the grille was flat and even with the front fenders. The newer Wrangler was constructed with a grille which angled out from the top, and then continued in a straight line from the midway point, toward the bottom. This decreased the hood length, while increasing the length of the fenders. In more recent models, this angle has been lowered more toward the bottom of the grille.

In Egypt, the YJ was produced as well as a long wheel-base version, dubbed LJ (or labeled as YJL in Egypt's Owners Manual), and which has retained the 2-door design. The YJL is considered as the first predecessor of the JK's long wheel-base by continuing as TJL (aka J8) which has directly inspired the JK's 4-door.

There is a Jeep Wrangler Pickup coming into production in 2017.

YJ (1987–1995)

Development of a potential CJ7 replacement was green-lighted in 1982, with engineering and design work (under Chuck Mashigan) commencing. After approval earlier in 1983, a final design freeze occurred by the fall of 1983, with CJ7-based mules being built in late 1983 and the first production body test prototypes in the spring of 1984. By late 1985, development concluded, as the transition from pilot to series production began. In February 1986, the 1987 Jeep Wrangler was unveiled, entering production that March, and going on sale on May 13, 1986.

The Jeep YJ, sold as the Wrangler in the United States, replaced the much-loved but slower-selling Jeep CJ in 1986 and was built in Brampton, Ontario, Canada, until the plant closed on April 23, 1992. Production was then moved to Toledo, Ohio, using the same plant that produced the Willys Jeeps during World War II. American Motors Corporation (AMC) had designed the new Jeep to be more comfortable on-road in an attempt to attract more daily drivers. It was an entirely new design with a wider track, slightly less ground clearance, and more comfort. The YJ still had leaf spring suspension similar to that of the CJ – however the springs were wider, and the YJs sported trackbars and swaybars for improved handling. Despite the new grille, the body is very similar to that of the CJ7, and it is interchangeable with some major modifications. The YJ also was given a larger windshield over the CJ. The YJs are easily identifiable due to the rectangular headlights and the fact that the wiper blades rest on the windshield giving this version a distinctive look. The blades rested on the windshield due to the now wider arc of the blades to clean the larger windshield. These two changes were later removed when the TJ was launched 1996. 632,231 YJs were built through model year 1995, although YJs were still sold into mid-1996, bringing the total production number to 685,071 units. Despite its similar look to the Jeep (CJ) its design was new from the ground up and had more in common with the newer downsized Cherokee (XJ) model.

TJ (1997–2006)

In 1990, development of a successor to the YJ began in Chrysler's "Jeep-Truck Engineering Pre-Program" department under Bob Sheaves and TJ program director, Craig Winn. Mules based on the YJ were built from 1990 to 1993, when formal approval was given for the TJ development program at a $260 million budget. From 1991 to 1992 designers worked at the new Chrysler Technical Center building on various design proposals. In late 1992, Michael Santoro's TJ proposal was chosen by Tom Gale, Lee Iacocca, and executive management. In May 1993, now with engineering and supplier input, Santoro's final Wrangler production design was frozen at 32 months ahead of initial assembly. Verification prototypes using production bodies were built from early 1994 and tested through late 1995. As YJ production ceased in December 1995, the last pre-production TJ examples were assembled, with start of series of production in January 1996.

Unveiled on January 2, 1996, at the 1996 Detroit Auto Show as an early 1997 model year introduction (1996 model year skipped), the TJ was an evolutionary update. It later arrived in Jeep showrooms in April 1996, after 6 years of overall investment and 36 month production development phase.

This updated Wrangler featured a coil-spring suspension (based on that of the Jeep Grand Cherokee) for better ride and handling, and a return to the classic CJ's round headlamps. The engine is the same 4.0 L AMC 242 Straight-6 used in the Cherokee and Grand Cherokee. A 2.5 L AMC 150 Inline-4 engine was available on entry-level models until 2002 when the 2.4 L DOHC 4-cylinder engine previously used on the Chrysler PT Cruiser replaced it.

A right hand drive version of the TJ was available for export markets, and was also offered for sale to U.S. rural route postal carriers. The version offered to U.S. postal carriers was only available with an automatic transmission.

JK (2007–present)

In 2001, DaimlerChrysler commissioned development of a TJ successor under the "JK" program code for the third generation Jeep Wrangler. Design work began almost instantly in 2001, with Mark Moushegian winning an internal design competition against Dan Zimmerman (later responsible for 2005 Jeep Hurricane Concept) by the second quarter of 2003. In January 2004, the JK design was frozen at 31 months ahead of production and work began on a conceptual preview.

On November 16, 2004, Jeep released 2 CAD renders of a Jeep pickup. On December 5, 2004, the 2005 Jeep Gladiator Concept was unveiled ahead of its January 2005 Detroit Auto Show debut, previewing many of the design elements on the incoming JK. The Wrangler JK was introduced at the 2006 North American International Auto Show with past Chrysler group CEO Tom LaSorda driving one up some steps and through a plate glass window, just as Robert Lutz had done at the show in January 1992 with the Grand Cherokee.

The 2007 model year brought a complete redesign of the Jeep Wrangler, and also a four-door model. The TJ chassis was replaced by an all new JK platform. This next-generation Wrangler was noticeably wider than the previous model, with a 3.4-inch (86 mm) wider track; and though the two-door model has a 2-inch (51 mm) longer wheelbase, it is actually 2.5 inches (64 mm) shorter in overall length than the TJ, allowing for a 44.3° approach angle and a 40.4° departure angle. With a larger factory available tire size of 32 inches, the breakover angle on the Rubicon is increased from 22.6° to 25.4°.

The four-door Unlimited model has an over 20-inch (510 mm) longer wheelbase at 116 in (2,950 mm) to offer much improved rear seating room, but is nevertheless only 2.4-inch (61 mm) longer than the 2006 TJ Unlimited.
