The Chrysler Pentastar engine family is a series of aluminum (die-cast cylinder block) Dual overhead cam 24-valve V-6 petrol engines introduced for model-year 2011 Chrysler, Dodge and Jeep vehicles. Chrysler has announced details, including the investment in plants ($2 billion, not including engineering of the engines themselves). The engine was initially named "Phoenix", but the name was changed before the official launch due to a trademark conflict. The Pentastar was introduced at the 2009 New York Auto Show.[1][2] The engine design also allows the use of E85 or 87 octane fuel, supports cylinder deactivation, and features dual variable valve timing. The Pentastar engine does not use EGR.[3]

Production

The Pentastar engines are made in Trenton, Michigan and Saltillo, Mexico. The Saltillo plant is set to begin production in the 2012 model year (with parts machined in Toledo, Ohio).

Insiders initially reported that the engine would come in four basic sizes (3.0L, 3.3L, 3.6L, and 4.0L), each offered in various states of tune. The 4.0L has been dropped from the list and a 3.2L added, according to Allpar as of November 2008 and October 2010, respectively, while Fiat's investor website, as of December 2011, specifies the 3.0L with Fiat's multi-air technology.[9] The 3.6 liter engine itself has different horsepower ratings in different vehicles, and has higher horsepower (305 hp) and torque (268 lb-ft) as used in the Dodge Challenger[10]

Twin and single turbocharged variants are planned for 2015. These engines are projected to produce around 420 and 370 horsepower respectively. Direct injection is also planned.[11]

Due to the new ownership structure, Fiat has obtained the right to use these engines, and currently adopt them in the larger models of Lancia and Fiat brands.
