KK, XK & MK Models

The Jeep Liberty (KJ/KK), or Jeep Cherokee (KJ/KK) outside North America, is a compact SUV produced by the Jeep marque of Chrysler. Introduced for the 2002 model year, the Liberty was priced between the Wrangler and Grand Cherokee. It was the smallest of the 4-door Jeep SUVs up until the car based 4-door Compass and Patriot arrived for 2007. The Liberty featured a unibody-on-ladder-frame construction, which added additional stiffness to its ride and handling, and enhanced its off-road capabilities. It is assembled at the Toledo North Assembly Plant in the United States, as well as in other countries including Egypt and Venezuela. Current estimates by Jeep, are that 70% of Liberty buyers are new to the marque.

Inspired by styling from the Dakar[6] and Jeepster[7] concept cars, the Liberty was intended as a replacement for the discontinued Jeep Cherokee (XJ). Three trim levels were initially offered; the top end Limited, a more rugged looking Renegade and the base Sport. All were made available with either 2WD or 4WD. In 2007, the Renegade trim level was replaced with the Latitude that appeared to focus more on an urban appearance.

The Liberty was the first Jeep to use two new PowerTech engines; the 150 hp 2.4 L I4, dropped in 2006, and the 210 hp 3.7 L V6. The VM Motori 2.8 L I4 common rail turbodiesel, became available in CRD branded 2005–2006 Sport and Limited models (2004 in the UK). The diesel utilized a variable geometry turbocharger and generated 160 horsepower (120 kW) and 295 pound-feet of torque. The overbuilt nature of the diesel powerplant added nearly 200 pounds to the CRD‘s curb weight versus the gasoline model. DaimlerChrysler introduced the CRD to gauge the marketability of diesel engines in North America; diesels are already common in Europe. The Liberty was also the first Jeep vehicle to use rack and pinion steering.[8]

2005–2007 Jeep Liberty

Only available in 2005 and 2006 for the Sport and Limited models, the 2.8L VM Motori CRD has since been discontinued due to stricter 2007 United States diesel emission standards. Maine, Vermont, Massachusetts, New York, and California had already banned sale of the vehicle due to their rigid state emissions regulations. A 3.0L CRD engine, based on a Mercedes-Benz BlueTec design, is still in production for the Jeep Grand Cherokee.

The Liberty was not the first Jeep vehicle to use an independent front suspension, as the Jeep Wagoneer first used it in the 1960s. However, the Wagoneer with the independent front suspension was never put into production, due to how fast the bushings would wear out. Jeep exceeded their expectations by selling 10,000 Liberty CRD models in its first calendar year of production. In addition, the Liberty was nominated for the North American Truck of the Year award for 2002.

Four Wheel Drive Systems

The Liberty is available with either a part time Command-Trac or full time Selec-Trac transfer case. The Command-Trac transfer case has four positions: 2-HI, 4-HI, Neutral, and 4-LO. The lever is placed in 2WD HI for regular driving, this allows the two rear tires to receive power. The second position, 4WD HI, is used for driving on slippery or loose pavement. This position locks both the front and rear drive shafts together splitting engine power equally between all four tires. The third position, Neutral, disengages both drive shafts from the transfer case allowing the car to roll freely; this is used for towing behind another vehicle, for example. The last position, 4WD LO is used for situations in which there is very little traction. This position, like 4WD HI locks both the front and rear drive shafts together, and by using a lower gear ratio, allows for 2.72 times more torque (however, the speed is limited to around 25 MPH max). It should be noted that using 4WD HI or LO on dry pavement is hazardous to vehicle components, through drive line binding and wheel-hop.

The Selec-Trac transfer case has five positions: 2-HI, 4-HI Part-Time, 4-HI Full-Time, Neutral, and 4-LO. This transfer case is different from the Command-Trac transfer only in the extra 4WD HI Full-Time position. The 4WD HI Full-Time position adds the same traction benefits that the part-time 4WD setting offers, but features an open differential between the front and rear axles to allow the two axles to spin at independent speeds and eliminate drive line binding and wheel-hop. The down side of 4WD Hi Full-Time is that, due to the open differential between front and rear drive lines, at times the drive train will only deliever power to the front or the rear e.g. when the front of the vehicle has reached a high traction surface such as dry pavement and the rear is in sand, the rear tires will spin with 100% of engine power, the front receiving no traction. Under equal traction conditions (front-rear) this position gives the rear wheels 60% of the engine’s power and the front wheels 40% of the engine’s power. The division of power and open center differential allows the Selec-Trac transfer case to be operated at all times in an “All Wheel Drive” mode with no adverse effects.

International versions

Numerous versions are available in markets outside the U.S. and Canada.

Early 02 – Mid 03 CRD’s were 2.5lt VM Motori Diesel and had 105Kw and 343Nm (std external wastegated turbo and Manual only)

A commercial Cherokee version with 2.5 CRD engine and five-speed transmission rated at 34.4 miles per imperial gallon (8.21 L/100 km; 28.6 mpg-US) has a completely flat cargo area (the rear seat area has a carpeted full-length galvanized metal floor) and the rear quarter glass and rear door glass is replaced with fixed body colored aluminium panels (the front doors have power windows). For additional cargo security a removable floor to ceiling metal and mesh bulkhead is optional. In European markets, VAT registered buyers can claim back the tax paid as this qualifies as a Commercial Vehicle.

The Jeep Liberty received a complete redesign for the 2008 model year with a more boxy and off-road look, like that of the 2007 Dodge Nitro, which is built on the same platform,[9] while the Nitro is not offered with low-range gearing. The 2008 Liberty debuted at the 2007 New York International Auto Show.[10]

The Liberty dropped its four-cylinder option because the Patriot and Compass crossover SUVs took its place as Jeep’s four-cylinder vehicles. The iron-block, aluminum-head V6 is the only engine available for 2008. Towing capacity is 5,000 pounds (2,268 kg). For now, there is no diesel model for the U.S. Jeep stopped building the Liberty CRD for the American market because it couldn’t meet tougher 2007 emissions standards. Transmission choices are both carry-overs: a six-speed manual or a four-speed automatic. Standard equipment includes electronic stability control with roll mitigation, traction control, and anti-lock brakes with brake assist. New Features include standard side airbags. Optional features are rain-sensing wipers, Sirius Satellite Radio, Bluetooth, a navigation system, and the MyGig entertainment system, complete with a 30GB hard drive.

Two models will be offered at rollout: Sport and Limited. Wheel choices are 16-, 17- and 18-inch (460 mm). Among the more distinctive features is the Sky Slider, a power roof made from “reinforced acrylic cloth” that opens over the front and rear seats. The Sky Slider opens up to 60 inches (1,500 mm) by 30 inches (760 mm), which is the largest opening in its class. Jeep claims that the idea behind the Sky Slider was to give consumers the open-air feeling from previous Jeep models while maintaining the rigidity and safety of a sturdy frame.[11]

The 2009 Liberty is relatively unchanged from the 2008 models with the exception of stiffer rear axle shafts and retuned springs, shocks, anti-roll bars, steering gear valve, low rollback brake calipers and a revised brake pedal ratio. Also the six-speed manual transmission is no longer available. The four speed automatic is now standard.

The Jeep Commander (XK) is a mid-sized SUV introduced in 2006. It was first introduced at the 2005 New York Auto Show. It is the 7-passenger counterpart of the Jeep Grand Cherokee. It has much more boxy styling, with an upright windshield and squared-off sides. The roof is stepped for the second and third-row seats (which are mounted higher than the first-row seats), but is disguised, as on the GMC Envoy XL, by a roof rack. It also features three moonroofs called “Command View”.

While the Jeep Wagoneer was the Commander’s initial inspiration, it is built upon the WK Grand Cherokee and resembles the discontinued third generation Jeep Cherokee (XJ).

The Commander offers a base V6 engine with an optional new Hemi: The Jeep commander comes with the optional entertainment package which includes a DVD player and TV and rear parking camera.

The Commander is scheduled to discontinue production beginning in 2011 model year, according to Chrysler-Fiat’s new 5-year restructuring plan.

In Europe and certain other markets like Chile, South Africa, and South Korea, the Commander offers a V6 Diesel engine developed by DaimlerChrysler with BlueTec technology:

The Jeep Compass (MK49) is a compact crossover SUV introduced for the 2007 model year. The Jeep Compass, along with the Patriot both slot below the Jeep Wrangler as Jeep’s entry-level sport utility vehicles, and is one of Jeep’s first crossover SUVs.

The Compass does not carry the “Trail Rated” badge found on other SUVs in the Jeep family. This indicates that the Compass targets first-time Jeep buyers and those who drive primarily on paved roads. Traditional Jeep vehicles, in contrast, have a reputation for off-road prowess, and some trace their origins to vehicles once used in ground operations by American troops.

The Compass and Patriot are both based on the DaimlerChrysler/Mitsubishi GS platform. These vehicles are differentiated by their styling and marketing: The Patriot is a traditionally styled 4-door Jeep wagon, while the Compass is closer to a hatchback or crossover like the Toyota Matrix. The Dodge Caliber, also based on the GS platform, is a combination of these two segments.

History

Four years prior to the introduction of the production Jeep Compass, a concept vehicle with the same name had its world premiere in Detroit at the 2002 North American International Auto Show. It featured a two door body, all-wheel drive and a 3.7-liter V6 engine. [3]

Jeep made its public debut of the production Compass at the 2006 North American International Auto Show in January. The first Compass was assembled on May 30, 2006, in Belvidere, Illinois, where the Chrysler Neon was produced. The Compass has a base price of $15,985 in the United States market.

In a press conference on November 4, 2009, Chrysler LLC, now under Fiat ownership, announced that both the Patriot and Compass would get modifications for 2010, but will be discontinued by 2012, to be replaced by a single Fiat-based model.[4]

Powertrain

The Compass uses a 172 hp (128 kW) 2.4 liter GEMA I4 gasoline engine. The 2.0 liter GEMA engine is available on the 4X2 Sport model. A 2.0 liter Volkswagen-designed diesel engine is available for the European and Australian markets. This diesel is the same as used in the Volkswagen Passat.

The car also features an electronically-controlled all wheel drive system with variable torque between speeds of 25 mph (40 km/h) and 65 mph (105 km/h) for optimal handling. However, the base model version has only Front wheel drive (FWD), a first for any Jeep. The Compass has not passed the same testing of off-road ability as other Jeep vehicles in terms of traction, ground clearance, maneuverability, articulation, and water fording. Although Chrysler has released a high-performance 2008 SRT4 version of the Dodge Caliber, as of the 2009 model year, there is no SRT Group (Street and Racing Technology) edition of the Compass.

he Jeep Patriot (MK74) is a cross-over vehicle introduced in early 2007 for the 2007 model year by the Jeep marque of Chrysler. It debuted publicly in April 2006 at the New York Auto Show. It slots between the Compass and Liberty in the Jeep lineup with pricing starting from $17,065 USD, making it the least-expensive sport utility vehicle in North America, which broke the record from the Jeep Liberty’s price tag in a previous model year. In a press conference on November 4, 2009, Chrysler LLC, now under Fiat ownership, announced that both the Patriot and Compass would get modifications for 2010, but will be discontinued by 2012, to be replaced by a single Fiat-based model.

Design

The Patriot and Compass are both based on the DaimlerChrysler/GS platform. These vehicles are differentiated by their styling and marketing: The Patriot is a traditional four-door Jeep wagon, similar to the Cherokee, which was discontinued in the U.S. in 2001, while the Jeep Compass is intended as a sporty crossover, but with more capacity to handle rough roads and poor weather than competitors like the Pontiac Vibe. The Dodge Caliber, also based on the GS platform, is a more direct competitor to the Pontiac Vibe and Toyota Matrix, and is more like a small hatchback than either of the Jeeps. The Patriot is manufactured at DaimlerChrysler‘s Belvidere, Illinois assembly plant alongside the Dodge Caliber and Compass.

The Patriot uses a four-cylinder 2.4 L GEMA gasoline I4 engine and also has a 2.0 L (1968 cc; 120 cid) Volkswagen-designed diesel engine for the European and Australian markets.[1] The base car features front-wheel drive, but a choice of two electronically-controlled four-wheel drive systems is optional. One, the Freedom Drive I, is a full-time system for on-road use. Freedom Drive II is made for off-road use with variable torque between speeds of 25 mph (40 km/h) and 65 mph (105 km/h) for optimal handling. The 2.0 L GEMA I4 is an option for the 4X2 model Patriot.

Off-Roading Capabilities

The Freedom Drive II-equipped Patriot uses a continuously variable transmission with a low range instead of a traditional two-speed transfer case, but has Jeep’s “Trail Rated” badging, signifying that it “has been designed to perform in five categories of off-road conditions: traction, ground clearance, maneuverability, articulation, and water fording.” The Freedom Drive II Patriot is among the most offroad-capable vehicles in its class, thanks in part to the presence of the off-road Brake Traction Control which is not available with Freedom Drive I. This allows the vehicle to maintain forward motion if one or two wheels lose traction by selectively applying brakes to the spinning wheels. This is a major improvement over a conventional AWD system in which a loss of traction in one front and one rear wheel at the same time would leave the vehicle stuck.

Electric version

At the 2009 North American International Auto Show in Detroit, the Jeep Patriot was added to Chrysler’s ENVI lineup. As with the previously announced Jeep Wrangler EV, the Jeep Patriot EV is an extended-range electric vehicle (EREV, also called a plug-in hybrid vehicle), capable of traveling 40 miles (64 km) solely on battery power and up to 400 miles (640 km) on a single tank of gas.[3]
