The 2007 Jeep Commander and the 2007 Jeep Grand Cherokee will operate on ethanol, if you happen to have an ethanol station in your area of course. The fuel, which is currently not readily available, is made from corn. In 2007, any Jeep Commander or Jeep Grand Cherokee that is purchased with a 4.7 liter engine will be able to run on the E85 variant of ethanol.
Other 2007 Chrysler Group vehicles that will support E85 are:
* Chrysler Sebring sedan and convertible with the 2.7-liter engine
* Dodge Dakota and Dodge Ram pickups and Dodge Durango SUV with 4.7-liter engine
