2011-2014 Jeep Wrangler and Wrangler Unlimited
With the NSG-370 manual transmission (the first manual to be connected to the Pentastar V6, and a carryover from the 4.0 and 3.8), the Jeep Wrangler can do 0-60 in under 7 seconds, not so long ago sports-car territory. See our main Jeep Wrangler page.
The 2012 Wrangler is available with 3.21, 3.73, or 4.10 final drive axle ratios, depending on model.
Gas mileage
* 285 hp (209 kW) @ 6,400 rpm. 260 lb-ft (353 Nm) @ 4,800 rpm. Redline 6,600 rpm. 87 octane (regular gas).
Gear ratios
Clearances and angles
The following table is for Wrangler, not Wrangler Unlimited. However, Wrangler Unlimited is similar.
For 2011, Rubicon got "Rock-Trac®" 4x4 which uses an electronic sway bar disconnect, Tru-Lok locking differentials (front and rear), and NV2410R transfer case with 4:1 gear ratio, fiving the Wrangler a 73:1 gear ratio. [Thanks to Justin Trevor for his clarification.]
Standard Wrangler 4x4s get Command-Trac I®, with shift-on-the-fly 4WD (at speeds under 60 mph), low gear, and neutral setting for towing without uncoupling the driveshafts. In low gear, for 2011 models, torque was multiplied by 2.72:1 (a 3.73 was also made available starting in 2012, and Rubicons have higher ratios). The front axle is a Dana 30, the rear axle is a Dana 44; a Trac-Lok differential is available.
