As one of the world’s most capable and most recognized, iconic vehicles, our 2012 Jeep Wrangler will become even better with its all-new, more powerful and fuel efficient 3.6-liter Pentastar VVT V6 engine and new five speed automatic transmission.
The 2012 Jeep Wrangler delivers unmatched off-road capability with legendary four-wheel drive capability and is produced with more than seven decades of 4x4 engineering and off-roading expertise. Jeep Wrangler continues to offer a body-on-frame design, front and rear five-link suspension system, live axles, electronic lockers, and is one of the few SUVs that offer a six-speed manual transmission – in addition to its new five-speed automatic transmission.
The Jeep Wrangler and Jeep Wrangler Unlimited will continue to be available in four models: Sport B (Wrangler only), Sport S, Sahara and Rubicon. Combined with an all-new interior for 2011, the 2012 Jeep Wrangler is virtually all-new over the past two model years and will excite core Jeep followers while appealing to new customers.
Chrysler Group’s 3.6-litre PentastarTM VVT V6 engine – winner of the prestigious Ward’s 10 Best Engines award – delivers 285 horsepower (209 kW) and 260 (353 N•m) lb.-ft. of torque, with greater fuel efficiency. The improvement, when compared to the previous 3.8-litre V6 engine, is 40 per cent in horsepower and 10 per cent in torque. Additionally, for refined shifting and greater performance, the Jeep Wrangler migrates from a four-speed to a new five-speed automatic transmission. The 2012 Jeep Wrangler also features the company’s first application of a manual transmission with the Pentastar VVT V6.
The all-new 3.6-litre Pentastar VVT V6 and five-speed automatic transmission dramatically enhance Jeep Wrangler’s on-road driving performance – delivering up to 9.5L/100 km (30 miles per gallon), 40 per cent more power and 10 per cent more torque – while also taking the vehicle’s legendary off-road capability to a new level.
The new automatic transmission benefits the 2012 Jeep Wrangler as much as the new engine with more refined shifting and gear selection. By increasing the number of speeds from four to five, the transmission allows the engine to operate in a more efficient RPM range, which helps increase fuel economy. More speeds also enable the engine to remain in the torque curve, increasing acceleration. The 2012 Jeep Wrangler boasts a 25-per cent improvement in 0-100km/h time, which is now 8.4 seconds. Also, a lower first-gear ratio in the new automatic transmission gives the Jeep Wrangler more off-road capability via a lower overall crawl ratio.
The Jeep Wrangler is now available with more axle gear ratios allowing customers to optimize fuel economy and/or vehicle capability. Jeep Wrangler is available with 3.21, 3.73 or 4.10 ratios depending on model. Also, Jeep Wrangler now offers 907 kg (2,000 lb) towing a 454 kg (1,000 lb) increase compared to 2011. Jeep Wrangler Unlimited offers towing capability up to 1,588 kg (3,500 lbs).
A best-in-class approach angle of 44.3 degrees, breakover angle of 25.5 degrees and departure angle of 40.4 degrees, helps the Jeep Wrangler scale even the toughest Canadian terrain.
The capable driveline of the Sport and Sahara models include a Dana® 30 front axle and Dana 44 rear axle. The Command-TracTM NV241, part-time, two-speed transfer case, features a 2.72:1 low-range gear ratio. In addition, an optional Trac-Lok® limited-slip rear differential provides extra torque and grip in low-traction environments such as sand, mud or snow.
The Jeep Wrangler Rubicon model features heavy-duty Dana 44 front and rear axles and the Rock-Trac® NV241 two-speed transfer case with a 4.0:1 low-range gear ratio. Jeep Wrangler Rubicon also includes electric front and rear locking differentials, disconnecting front sway bar and 32-inch tall BFGoodrich® tires, taking the Jeep Wrangler to the highest level of capability.
In 2011, Jeep introduced an all-new interior to Jeep Wrangler that combined rich styling, versatility, comfort and improved feature use. Highlights included upgraded materials, automatic temperature controls, heated cloth or leather-faced seats, power heated side-view mirrors and steering-wheel mounted cruise and audio controls. Larger rear windows and tailgate opening were engineered for greater visibility and accessibility. Jeep Wrangler also offers a USB port that connects to the media centre, 12-volt accessory outlets and a 115-volt AC outlet to power select two-pronged home electronics.
The Jeep Wrangler’s signature features include classic round headlamps, seven-slot grille, trapezoid wheel flares, removable doors, exposed hinges, a fold-down windshield and innovative removable and convertible tops and half doors that allow the Jeep Wrangler to retain the brand’s iconic appearance and function. New for 2012, Jeep Wrangler Rubicon models now share a modular body-colour Freedom Top® hardtop option along with body colour fender flares with the Jeep Wrangler Sahara model, offering a premium appearance.
With room for five adults, Jeep Wrangler Unlimited remains the only four-door 4x4 convertible on the market.
The 2012 Jeep Wrangler and Jeep Wrangler Unlimited are available with an array of safety, security, and technology features. Standard electronic stability control, electronic roll mitigation, Trailer-sway Control, Hill-start Assist and brake traction control are among two dozen available safety and security features. Jeep safety systems are engineered to improve handling and accident avoidance while providing occupant protection, allowing Jeep Wrangler customers the ability to safely "Go Anywhere, Do AnythingTM."
The 2012 Jeep Wrangler stays connected with UconnectTM systems, including voice recognition, Bluetooth® streaming audio, navigation and SiriusXM™ Satellite Radio. The Jeep Wrangler’s connectivity systems have improved ergonomics by giving the driver control at their fingertips. Intuitive buttons on the front and rear of the steering wheel control a number of features allowing the driver to keep hands on the wheel and eyes on the road.
The 2012 Jeep Wrangler underwent millions of durability testing kilometres during development in the company’s scientific labs, at its proving grounds and on public roads in various climates.
The Jeep Wrangler’s 3.6-litre PentastarTM VVT V6 engine recorded more than 19 million customer-equivalent kilometres on engine dynamometers prior to production. Testing was increased by 50 per cent compared to previous Chrysler Group V6 engines, to guarantee a long life against severe conditions and accommodate high-load applications such as trailer towing. Reducing noise, vibration and harshness was a key objective for every engine component and was achieved using advanced computer-aided engineering techniques.
As the Jeep Wrangler approached production, the company also tested day and night, on- and off-road to put three years’ worth of wear and tear on the vehicle in approximately three months of time. This accelerated testing occurred on public roads, paved and unpaved, in an attempt to find and fix any issues before the first SUVs were delivered to customers. The test drivers checked all the functional aspects of the vehicle, such as heating and cooling, window operation, convertible and removable hardtop operation and navigation system functionality.
The 2012 Jeep Wrangler and Jeep Wrangler Unlimited are built in the Toledo Supplier Park in Toledo, Ohio, U.S.A. The plant features the flexibility to integrate the all-new powertrain with the addition of new engine carriers and transmission lift equipment.
Both the Pentastar engine and five-speed transmission are built in the United States with the 3.6-litre V6 engine manufactured at the Trenton engine plant in Michigan and the five-speed automatic transmission produced in Kokomo, Indiana (ITP2). The manual six-speed transmission is produced in Gaggenau, Germany.
Jeep Wrangler Sahara and Jeep Wrangler Rubicon models offer a body-colour hardtop. A new paint process was developed to match the body-colour to the sheet moulded compound (SMC) hardtops that exceeds the corporate quality standards of paint adhesion and UV resistance in the harshest environments. The body and top are painted separately with blended and matched paint to assure colour continuity.
