The '''Chrysler Pentastar''' engine family is a series of [[aluminium]] ([[Die casting|die-cast cylinder block]]) [[dual overhead cam]] [[Multi-valve#Four valves|24-valve]] [[gasoline]] [[V6 engine]]s introduced for the 2011 model year in [[Chrysler (brand)|Chrysler]], [[Dodge]], [[Ram Trucks|Ram]] and [[Jeep]] vehicles. The engine was initially named "[[Phoenix (mythology)|Phoenix]]," but the name was changed before the official launch due to a trademark conflict; the [[History of Chrysler#Pentastar|Pentastar]] name is derived from the trademark of the former Chrysler Corporation, which dates back to 1963. It will eventually be replaced by the [[FCA Global Medium Engine|Hurricane 4 EVO]] engine as the main corporate engine for [[Chrysler|Stellantis North America]].
==Production== The Pentastar engines are made in three different factories: [[Dundee Engine Plant]], [[Trenton Engine Plant]] and [[Saltillo South Engine Plant]].<ref>{{cite press release |url= http://media.chrysler.com/newsrelease.do;jsessionid=04CD2C578F893CBB1146B87A5D281660?&id=9117&mid=18 |title=FCA US LLC Manufacturing Operations |website=media.chrysler.com |access-date=11 May 2015}}</ref>

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 [[engine tuning|various 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's [[MultiAir]] technology.<ref>{{cite web|url= http://www.fiatspa.com/it-IT/investor_relations/investors/presentazioni/FiatDocuments/2011/UBS%20Auto%20Show%20Investor%20Conference%20-%20Frankfurt%20%28Sep%2014%202011%29_site.pdf |title=2011 Fiat Investor Site |website=Fiatspa.com |date= |accessdate=2011-12-07}}</ref> The 3.6 L engine itself has different power ratings in different vehicles, and has higher output {{cvt|305|hp|kW PS|0}} and {{convert|269|lb·ft|N·m}} of torque when applied in the Dodge Challenger.<ref>{{cite web|url= http://www.allpar.com/cars/dodge/challenger/challenger-2011.html |title=2011 Dodge Challenger cars |website=allpar.com |date= |accessdate=2010-10-26}}</ref>
Single and [[Twin-turbo]]charged variants had been planned for 2015. These engines were projected to produce around {{cvt|420|and|370|hp|kW PS|0}}, respectively. Direct injection was also planned.<ref>{{cite web|url= https://www.allpar.com/threads/phoenix-chrysler-pentastar-v6-engines-for-2010-and-beyond.229985/#post-1085224083 |title=Chrysler Pentastar V6 Engines for 2010 and Beyond |website=allpar.com |date=November 16, 2020 |accessdate=January 13, 2023}}</ref>
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.

==Pentastar upgrade{{Anchor|PSU}}== For 2016, FCA released an updated version of the 3.6 L engine. 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 injector]]s, new [[ignition coil]]s, a cooled [[Exhaust gas recirculation]] system, 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,<ref>{{cite web|url= http://www.autoblog.com/2015/09/02/fca-pentastar-v6-2016-upgrades/|title = FCA's Pentastar V6 gets more power, efficiency for 2016 |date = 2015-09-02 | work = Autoblog |last=Bruce | first=Chris |archivedate= 2017-05-10 | archiveurl = https://web.archive.org/web/20170510165537/https://www.autoblog.com/2015/09/02/fca-pentastar-v6-2016-upgrades/ }}</ref> however the new version no longer supports [[flex-fuel]] capability.
