Jeep Wrangler is now available with an all-new, more fuel efficient and more powerful 3.6-liter V-6 engine that results to a better on- and off-road performance. It is equipped with a new five-speed automatic transmission that is also used by the Jeep Grand Cherokee. When used on the 2012 Jeep Wrangler, the 3.6-liter Pentastar V-6 engine could produce 285hp (209 kW) and 260 (353 N•m) lb.-ft. of torque.
It offers up to 21 miles per gallon highway. This engine had been recognized with the Ward’s 10 Best Engines award. Compared to the previous 3.8-liter V-6 engine, this new engine offers a 40% boost in horsepower and 10% in torque.
In addition, the Jeep Wrangler uses a new five-speed automatic transmission instead of a four-speed. This move was made to have refined shifting and improved performance. The 2012 Jeep Wrangler also marks the first time that the company applies a manual transmission to the Pentastar V-6. Jeep improves on the effective Wrangler formula by combining iconic, benchmark capability with an interior that offers rich styling with upgraded touch surfaces, comfort and versatility.
It also gets a premium appearance as the result of a body-color hardtop for the Sahara and Rubicon models. The interior highlights of the 2012 Jeep Wrangler include a newly redesigned instrument panel and storage areas with enhanced ergonomics and upgraded materials.
More comfort is offered at the touch points courtesy of a lockable console and upgraded door armrest areas. Meanwhile, the center stack has been redesigned to be easier to access and operate. Buyers may opt for heated, power mirrors. Its large rear windows provide better visibility to its passengers and drivers.
The Jeep Wrangler is a living legend among four-wheel drive vehicles because of its superior off-road capabilities, thanks to the company’s 70-plus years of experience in developing 4x4s. The Wrangler today still offers a body-on-frame design, live axles, electronic lockers and five-link suspension systems for the front and rear wheels.
There are now two transmissions available for the 2012 Jeep Wrangler: six-speed manual and five-speed automatic.
Jeep’s engineers made comprehensive optimisations for the ride and sound attributes of the new Wrangler’s body-on-frame design and new powertrain. Engine, transmission and suspension system calibration improvements result in noticeably enhanced on- and off-road ride characteristics.
2012 Wrangler’s improved cabin sound quality can be attributed to the utilisation of a new engine cover that provides effective dampening of engine and road surface noise. Additional contributions are also provided by the firewall noise damping and the systematic enhancements for the powertrain mounting system.
Exteriorly, the engine’s noise is hardly audible when idle. This engine is a 3.6-litre V6 with directly-mounted accessories (no brackets) for improved anchorage resulting in lower vibration and noise, even for the power steering pump, alternator and air conditioning compressor.
The Wrangler’s shocks have also been precisely modified for an ideal balance between the vehicle’s on- and off-road performances.
