The Jeep Wrangler is a compact four-wheel drive sport utility vehicle (SUV) and an off-road vehicle manufactured by American automaker Chrysler, under its Jeep marque – and now in its fourth generation. It is a successor to the famous World War II 'Jeep' vehicle by way of the Willys civilian Jeep (CJ) in the 1950s, later produced by Kaiser-Jeep and by American Motors (AMC). The Wrangler debuted in 1987, was revised in 1997 and again in 2007. Wranglers continue to use live axles both front and rear as with their predecessor, the CJ.Each Wrangler model has received a designation in addition to the nameplate Wrangler corresponding to their generation: YJ (1987–1995), TJ (1997–2006), LJ's (2004-2006 Unlimited models) and JK (2007–present). Military versions of the Wrangler have carried the J8 designation.
YJ models were manufactured between 1987 and 1992 in Brampton, Ontario and subsequently at the Toledo South Assembly plant until mid-1995. TJ and LJ models were subsequently manufactured in Brampton, Ontario as well. After that plant's razing, JK models have been at the Toledo North Assembly plant in Toledo, Ohio.
The JK series 2007 Wrangler Unlimited was unveiled at the New York Auto Show on April 12, 2006. It is stretched even more than the TJ model, with four doors (becoming the last-remaining 2-door SUV in North America to gain a four-door option) and 20.6 inches (523 mm) added to the JK Wrangler's 95.4-inch (2423 mm) wheelbase. It is priced near $21,000.
Unlimited has the same engine and transmission choices as a short-wheelbase JK. X and Sahara trims offer an option of 4x2 rear wheel drive in the U.S.A. It is the only four door convertible available in the U.S., since the Hummer H1 with optional rag-top is no longer sold.
The Unlimited offers more options and equipment than any previous Wrangler model, including standard electronic stability program and optional seat-mounted side airbags, remote keyless entry, navigation system, and Sirius Satellite Radio.[15] The navigation and satellite systems are a part of the MyGig Entertainment system that also has a hard drive allowing for the storage of MP3 music files and pictures.[16]On September 13, 2007, at the Defence Systems and Equipment International trade show, Chrysler LLC unveiled a Wrangler Unlimited version designed for military use dubbed the J8. The unarmored Jeep J8 is equipped with larger brakes, axles and suspension components than the civilian version and has a payload capacity of 1,339 kg (2,952 lb). The J8 also differs from the civilian model by utilizing heavy-duty rear leaf springs for carrying heavier payloads. The Jeep J8 is powered by a 2.8-liter four-cylinder turbo-diesel engine that produces 118 kW (158 hp) and 400 N·m (295 lbf·ft) of torque, providing towing capability of up to 3,500 kg (7,700 lb). The engine is mated to a five-speed automatic transmission. The J8 also features a unique air-intake system with special filtration and a hood-mounted snorkel that enables the J8 to wade in water up to 762 mm (30 in) deep and tackle sandstorm conditions for up to five hours. Available as a two-door with an extended pickup bed for personnel or equipment transport, or a four-door multipurpose vehicle, it may be produced with numerous vehicle-body and seating configurations in either right-hand- or left-hand-drive. Targeted for use by the militaries in overseas markets, the J8 is not available in the United States because it will not meet U.S. emissions requirements. The J8 will be produced in Egypt. The 2009 model added standard Hill Start Assist (HSA) to prevent rollback on graded surfaces. Trailer Sway Control (TSC) also is available to monitor vehicle movement relative to the intended path and activates the Electronic Stability Program (ESP) if the trailer begins to sway outside set parameters. Additionally, ULEV II emissions replace LEV II emissions on manual transmission equipped vehicles. Graphic showing the various suppliers used for the 2011 Wrangler.
The 2011 model added a new steering wheel, as well as a completely redesigned interior with higher quality materials, larger rear windows to increase rear visibility, and a new USB interface with Bluetooth audio streaming. For the first time ever, automatic temperature controls were also added to the Wrangler as an option. The redesign was intended to provide a more refined interior as well as directly addressing interior comfort in noise and temperature.
The 2012 model, as confirmed by Chrysler CEO Sergio Marchionne during the 2010 third-quarter sales announcement will receive a version of Chrysler's newest V-6 engine known as Pentastar.
