A new version of the Pentastar V6 will see MultiAir 2 replacing the cam phasing system, according to an anonymous, unsubstantiated source. While the veracity of the statement is unknown, the move has been rumored since 2009.
It is possible that Chrysler is creating a premium version of the engine. A premium version would not be out of the question, for applications where power ratings, reduced carbon emission, or gas mileage is more important than the higher cost (e.g. in cars sold in Europe). Along with direct injection, MultiAir 2 is likely two to four years away.
