The 3.6L Pentastar engins is used on the Durango, Cherokee, Charger, Challenger, Journey, Wrangler, Liberty... Just about all of the MOPARs except Fiat (yet... since the only model they got in the states so far is the 500 which uses the 1.4L and the Abarth that uses a turbo 1.4L, both of which is going to the Dart/Dart SRT4)
