Chrysler Pentastar engine

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.

Production
The Pentastar engines are made in three different factories: Dundee Engine Plant, Trenton Engine Plant and Saltillo South Engine Plant.

The Pentastar engine was introduced at the 2009 New York Auto Show. The engine design allows the use of E85 or 87 octane fuel and features dual variable valve timing. Forced induction, and cylinder deactivation options were engineered into the engine design, but have not been implemented from the factory, remaining "on the shelf" as of 2016.

Insiders initially reported that the engine would come in four basic sizes (3.0, 3.3, 3.6, and 4.0 L), each offered in various states of tune. The 4.0 L has been dropped from the list and a 3.2 L added, while Fiat's investor website, as of December 2011, specifies the 3.0 L with Fiat's MultiAir technology. The 3.6 L engine itself has different power ratings in different vehicles, and has higher output 305 hp and 268 lb·ft of torque when applied in the Dodge Challenger.

Single and Twin-turbocharged variants had been planned for 2015. These engines were projected to produce around 420 and 370 hp, respectively. Direct injection was also planned.

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

This engine features upgrades to the variable valve timing (VVT) system, two-stage variable valve lift (VVL), a new intake manifold, new valve springs, new piston rings, new fuel injectors, new ignition coils, a cooled EGR, lower internal friction and lower weight.
