( http://www.TFLcar.com ) The 2012 Jeep Wrangler finally gets a significant boost in power with the introduction of the 3.6L Chrysler Pentastar engine that puts out 285 horse power. The old 3.8L engine was only rated at 202 HP. So that obviously begs the question which Jeep Wrangler  is the faster...the 2011 or the 2012? Check out this drag race to find out.
