The Chrysler Pentastar engine family is a series of aluminium (die-cast cylinder block) dual overhead cam 24-valve gasoline V6 engines introduced for the 2011 model year in Chrysler, Dodge, and Jeep vehicles. The engine was initially named "Phoenix," but the name was changed before the official launch due to a trademark conflict; the Pentastar name is derived from the trademark of the former Chrysler Corporation, which dates back to 1963.
