The 2009 Jeep Liberty is equipped with a 3.7-liter six-cylinder engine that produces gas mileage ratings of 16 city/22 highway (2WD) and 15/21 (4WD).
Although a manual transmission had been available starting with the 2002 Liberty, all 2009 Liberty models are fitted with a four-speed automatic transmission, exclusively. A more fuel efficient 2.4-liter four cylinder engine was available in the 2003 through 2005 Liberty.
