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.{{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}}

The Pentastar engine was introduced at the 2009 New York Auto Show.{{cite web |last=Joseph |first=Noah |url= http://www.autoblog.com/2009/04/13/chryslers-flexible-new-pentastar-v6/ |title=Chrysler's flexible new Pentastar V6 |website=Autoblog.com |date=April 13, 2009 |accessdate=2010-09-29}}{{cite web |url=http://www.redletterdodge.com/2009/04/08/ny-show-chrysler-llc-introduces-all-new-pentastar-v-6-engine/ |title=NY Show: Chrysler LLC Introduces All-new Pentastar V-6 Engine |website=Redletterdodge.com |date= |accessdate=2010-09-29 |archive-url= https://web.archive.org/web/20090416211715/http://www.redletterdodge.com/2009/04/08/ny-show-chrysler-llc-introduces-all-new-pentastar-v-6-engine/ |archive-date=April 16, 2009 |url-status=dead }} 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.{{cite web |url= http://articles.sae.org/14322/|archiveurl= https://web.archive.org/web/20151105035742/http://articles.sae.org/14322/ |archivedate=2015-11-05|url-status=dead |title=2016 Pentastar V6 adds new VVT, cooled EGR}}

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 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.{{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}} 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.{{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}}

Single and Twin-turbocharged 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.{{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}}

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 injectors, new ignition coils, 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,{{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/ }} however the new version no longer supports flex-fuel capability.
