Jeep Wrangler JK 07-Present

The 2007 model year brought the complete redesign of the Jeep Wrangler, in both two- and four-door models. The TJ platform was replaced by a new JK platform. This next-generation Wrangler was significantly larger than the existing model, with a 2-inch (51 mm) longer wheelbase and 3.4-inch (86 mm) wider track, though the two-door model is actually 2.5 inches (64 mm) shorter in the overall length than the TJ, allowing for a 44.3-degree approach angle and a 40.4-degree departure angle. With a larger available standard tire size of 32 inches; break over angle is unchanged.

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 1992 with the Jeep Grand Cherokee. The JK was first available for purchase with the 2007 model year.

The JK Wrangler is offered in two versions:

• A short-wheelbase 2-door, in X, Sahara and Rubicon trim levels.
• A long-wheelbase Unlimited 4-door, also in X, Sahara and Rubicon trim levels.

The Wrangler X is available with factory installed right-hand drive, targeted at US mail carriers. Rural mail boxes in the United States are serviced with the carrier behind the wheel. This may also be useful for carriers who wish to get out of their vehicle without the risk of getting hit by traffic. For the 2007 and 2008 model years, the short-wheelbase Wrangler was the right-hand drive Jeep. For the 2009 model year, the right-hand drive Wrangler will be replaced by the right-hand drive Wrangler Unlimited.

A 3.8 L EGH V6 with a displacement of 230.5 cubic inches (3,778 cc) producing (202 hp (151 kW) and 237 foot-pounds (321 N·m) of torque is the base engine, replacing the venerable AMC 242 straight-6. The 2.8 L VM Motori turbo diesel straight-4 producing 177 hp (132 kW) and 302 foot-pounds (409 N·m) of torque used in the Liberty is offered as options outside of U.S., as it does not satisfy U.S. emission control standards for 2007.

A six-speed manual transmission is standard, with a four-speed automatic transmission offered as an option. The lower two levels have the Jeep Command-Trac NV241 part-time two-speed transfer case with an optional Trac-Loc limited-slip differential, while the Rubicon uses a Rock-Trac version of the NV241 with a 4:1 low range. Electronic locking front- and rear-axles called Tru-loc are also standard on Rubicon models. (A rear locking differential was optional on X and Sahara models for 2007, then only on select X models for 2008 and 2009. From 2010 onward, the locking differential is not available on any non-Rubicon Wrangler.)

Stability control is a new safety feature for the JK Wrangler. All versions offer off-road tuned Anti-lock braking system and traction control system with electronic limited slip differential. Standard on the Rubicon trim is a new electronic sway bar disconnect system.

The JK runs almost all vehicle functions other than steering under computer software control. Engine, transmission, and to some extent braking is computer controlled, as are lights and auxiliary systems. This is a first for the Wrangler. As of mid-2007, there have been three safety recalls for software fixes.

A Sunrider convertible soft top is standard equipment. Also available on the JK model is an optional 3-piece modular hardtop. Although the doors can still be removed in traditional Wrangler fashion, power windows and remote power door locks will be offered for the first time in a Wrangler. Another first is an available navigation system. This is the first generation of the Jeep Wrangler to have a change in the tail lamps.

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 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 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 VM 2.8-liter (169 CID) four-cylinder turbo-diesel engine that produces 118 kW (158 hp) and 400 N·m (295 lb·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.

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 received a version of Chrysler's newest V-6 engine known as Pentastar. The version used in the 2012 Wrangler and Wrangler Unlimited produces 285 horsepower and 260 lb-ft of torque. Fuel economy for the 2-door model is rated at 17 mpg City / 21 mpg Highway.
