TheChrysler Pentastarengine family is a series ofaluminium(die-cast cylinder block)dual overhead cam24-valvegasolineV6 enginesintroduced for the 2011 model year inChrysler,Dodge,andJeepvehicles. The engine was initially named "Phoenix,"but the name was changed before the official launch due to a trademark conflict; thePentastarname is derived from the trademark of the former Chrysler Corporation, which dates back to 1963.

Production

edit

The Pentastar engines are made in three different factories:Dundee Engine Plant,Trenton Engine PlantandSaltillo South Engine Plant.[1]

The Pentastar engine was introduced at the 2009New York Auto Show.[2][3]The engine design allows the use of E85 or 87octane fueland features dual variable valve timing.Forced induction,andcylinder deactivationoptions were engineered into the engine design, but have not been implemented from the factory, remaining "on the shelf" as of 2016.[4]

Insiders initially reported that the engine would come in four basic sizes (3.0, 3.3, 3.6, and 4.0 L), each offered invarious states of tune.The 3.3 L and 4.0 L have been dropped from the list and a 3.2L added, while Fiat's investor website, as of December 2011, specifies the 3.0 L with Fiat'sMultiAirtechnology.[5]The 3.6 L engine itself has different power ratings in different vehicles, and has higher output 305 hp (227 kW; 309 PS) and 269 pound force-feet (365 N⋅m) of torque when applied in the Dodge Challenger.[6]

Single andTwin-turbochargedvariants had been planned for 2015. These engines were projected to produce around 420 and 370 hp (313 and 276 kW; 426 and 375 PS), respectively. Direct injection was also planned.[7]

Due to the new ownership structure,Fiathas obtained the right to use these engines, and had adopted them in the larger models ofLanciaandFiatbrands.

Pentastar upgrade

edit

For 2016, FCA released an updated version of the 3.6 L engine. This engine features upgrades to thevariable valve timing(VVT) system, two-stagevariable valve lift(VVL), a newintake manifold,new valve springs, newpiston rings,newfuel injectors,newignition coils,a cooledExhaust gas recirculationsystem, lower internal friction and lower weight. It also features a higher compression ratio, increased from 10.2:1 to 11.3:1. These improvements increase power as well as efficiency,[12]however the new version no longer supportsflex-fuelcapability.
