The new automatic transmission benefits the 2012 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-percent improvement in 0–60 mph time, which is now 8.4 seconds. Also, a lower first-gear ratio in the new automatic transmission gives the Wrangler more off-road capability via a lower overall crawl ratio.
Jeep Wrangler is now available with more axle gear ratios allowing customers to optimize fuel economy and/or vehicle capability. Wrangler is available with 3.21, 3.73 or 4.10 ratios depending on model. Also, Wrangler offers towing capability up to 3,500 lbs.
A best-in-class approach angle of 44.6 degrees, breakover angle of 25.5 degrees and best-in-class departure angle of 40.6 degrees, helps the Jeep Wrangler scale the toughest terrain.
The capable driveline of the Sport and Sahara models include a Dana 30 front axle and Dana 44 rear axle. The Command-Trac® 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 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. Rubicon also includes electric front and rear locking differentials, disconnecting front sway bar and 32-inch tires, taking the Wrangler to the highest level of capability.
In 2011, Jeep introduced an all-new interior to Wrangler that combines rich styling, versatility, comfort and improved feature use. Highlights include upgraded materials, automatic temperature controls, heated seats, power mirrors and steering wheel controls for vehicle systems. Larger rear windows are engineered for greater visibility. A USB port connects to the media center, 12-volt accessory outlets are located throughout the Wrangler and a 115-volt AC outlet is available to power select two-pronged home electronics.
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 Wrangler to retain the brand’s iconic appearance and function. New for 2012, Wrangler Rubicon models now share a body-color hardtop option with the Sahara model, offering a premium appearance.
With room for five adults, Jeep Wrangler Unlimited remains the only four-door 4×4 convertible on the market.
