( http://www.TFLcar.com ) The 2012 Jeep Wrangler finally gets the new Chrysler Pentastar V-6 engine and 5 speed automatic or 6 speed manual transmission to not only compete in today's crowded Crossover and SUV segment, but rule the off-road world. More power and torque, better gas mileage and the same base price. What's not to like?
