Jeep Wrangler

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 Jeep YJ, sold as the Wrangler, replaced the much-loved but slower-selling Jeep CJ in 1987 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 back in WWII. The 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 a new design with a wider track, slightly less ground clearance, and more comfort. The YJ also had a 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 grill, the body is very similar to the CJ7's, and it is interchangeable with some minor modifications. The YJ also was given a larger windshield over the CJ. The YJs are easily identifiable due to the rectangular headlights, disliked by some Jeep aficionados, 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 changes came about in 1996. 632,231 YJs were built through model year 1995, although YJs were still produced into mid '96, bringing the total production number to 685,071 units.

The YJ used a 2.5 L AMC 150 I4 or optional 4.2 L AMC 258 I6 until 1991. That year, a fuel injected 180 hp (134 kW) 4.0 L AMC 242 variant replaced the 112 hp (84 kW) 4.2 L 258 CID straight-6. The NP207 transfer case was used only in 1987 and replaced by the NP231

The roll cage was extended in 1992 to allow for rear shoulder belts, and anti-lock brakes were added as an option the next year. An automatic transmission option for 4-cylinder Wranglers came in 1994, along with a center high-mounted stop lamp.

In 1994, the slave cylinder on manual transmissions was moved outside of the transmission's bellhousing to allow for easier replacement, and in 1995 the Dana 30 larger U-joints were used [front axle U-joints (297x) and rear pinion U-joint (1330)]. For the 1992 model year, the YJ switched over to an electronic speedometer outmoding the cable speedos on older YJs. 1995 was the only year to have a fully galvanized frame and body.

There were no 1996 model year Jeep Wranglers. YJs produced in early 1996 were sold as 1995 model years, but featured a few new parts not seen on any earlier YJ. This included the new TJ bumpstops on the hood (rubber boots vs the traditional U-bars), reinforced tailgate hinges, and some even had rear TJ bumpers. Some also got the newly tuned I6 that was designed to run quieter in preparation for the TJ.

Top options for YJ were the same as those offered on TJ. A Soft top with "half doors", featuring soft plastic zipper windows came standard (windows could be removed completely from these doors). Full frames doors with conventional glass windows were optional on soft-top models. Hard tops with rear wiper and defroster were optional, but came standard with full framed doors. YJ featured large mirrors with manually adjustable arms on half door models, while full framed doors received smaller adjustable mirrors with fixed arms (which were mounted further away from the door corner, compared to the larger style mirrors). Depending on year and interior color, Jeeps could be had with the top colors in black, white, tan and gray. Roll bar padding normally matched top color, with the exception of white tops.

YJ Wrangler Islander

From 1988 until 1993, Jeep produced an options package known as the "Islander". Several colors were offered, such as Bright Red, Sunset Yellow, Teal, and White, and both engines were offered. Features of the package are as follows:
Body color wheel flares and side steps
Sunset graphics on lower body and hood
Islander logo on front fenders and spare tire cover
20 gallon fuel tank
Gray interior and highback leather seats
Optional 5-spoke Alloy Wheels
Floor carpeting
Center console with cupholders
Full or half doors

YJ Wrangler Renegade

From 1991 until 1994, Jeep produced an options package on the YJ Wrangler listed as the "Renegade Decor Group". Initially, all Renegades were White, Black or Red. In 1992, Blue was added, in 1993, Bronze. The Renegade Decor Group was a $4,266.00 option over a base Wrangler in 1991 and included special alloy wheels, exclusive body flares, along with many other features.

A hardtop was a $923.00 option and came with a mandatory rear window defroster at a $164.00 premium. Although soft-top models came standard with "half doors", full framed doors with glass windows were an option. Renegades typically had the tilt steering wheel ($130.00) and an AM/FM/cassette stereo radio ($264.00). A column shift automatic was also an available option, but it was not popular. While a base Wrangler with the inline-6 went for $12,356.00, the Renegade package pushed that price up to $18,588.00 in 1991.

These vehicles were sent as optioned Wranglers to Auto Style Cars in Detroit, where the Renegade Decor Package was installed, then shipped back to Jeep for delivery to dealers. Renegades all have a small sticker on the driver's side door, right above the latch denoting the visit to ASC.

At the price premium over a standard Wrangler, sales were fairly limited, so finding one today is a semi-rare occurrence. The price, plus what hardcore Jeepers felt were "funny looking plastic fenders" limited the sales. Although having nearly identical off-road capabilities, these Jeeps were typically used as "beach cruisers" due to their premium price and rarity, as well as because their over sized flares and body cladding were not necessarily designed for the abuse that tree branches and over-sized tires can often cause.

Jeep Wrangler unlimited

JK Wrangler Unlimited

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. 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.

On September 13, 2007, at the Defence Systems & 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.

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. There is a growing demand for now parent company, Fiat (Fiaty.pk), to introduce a diesel engine option for the Jeep Wrangler for better fuel economy and performance.

The Jeep Wrangler received the 2009 Best Resale Value Award from Kelley Blue Book (KBB) in the Sport Utility Vehicle category. The Wrangler also holds the "Models to Best Hold Its Value" recognition from Kelley Blue Book for 1999, 1998, and 2003.

The 2008 edition of Forbes Autos lists the four-wheel-drive convertible Jeep Wrangler at number four among the top ten vehicles with the highest resale value.

In May 2009, Business Week magazine named the Wrangler "One of the Most Iconic Cars of the Last 20 Years."

Electric Wrangler

In September 2008, Chrysler Vice Chairman Tom LaSorda unveiled a range-extended electric 4-door Wrangler along with similarly engineered Town and Country minivan and a purely electric sports car. The Wrangler would have a 40-mile (64 km) range before a gas engine starts and begins supplying additional electricity. However, in November 2009 Fiat SpA disbanded Chrysler's ENVI electric car division and dropped these models from future product plans.

With a 24-year history, Jeep Wrangler is one of the most successful models in the Jeep part. Currently in its third generation (JK since 2007), Wrangler is about to receive one of the most important updates for the 2012 model year.

So far, Wrangler was equipped with a 3.8-liter V-6 engine, which delivered a total of 202 hp and 237 Nm of torque. This engine was not bad, but it lacks the power required for the Wrangler to really flex its muscles during these off-road events. In 2012, things will change, how boring V6 engine was dropped in favor of a new 3.6-liter Pentastar V-6 engine, which provides a total of 290 hp and a maximum torque of 237 lb-ft.

2012 Wrangler has been announced in a jeep, but the Georgia based dealer has already posted a version of the Rubicon for sale on eBay for $ 35,628.

For 2012, Wrangler Rubicon will continue with the same features that have been identified for the 2011 model year: redesigned instrument panel and new storage area with improved ergonomics and upgraded materials.

The interior will be offered with cloth seats, driver seats height adjustment, front seat-back pocket cards, a leather steering wheel, and Hill Descent Control.

The standard equipment list includes: Cruise control with steering wheel controls, hydraulic Power-Assist, Cruise Control, Manual convertible roof for a model of the Rubicon and Travel SIRIUS Link.
