The '''Cyclone''' engine, also branded '''Duratec''', is [[Ford Motor Company]]'s latest [[Double overhead camshaft|DOHC]] family of gasoline [[V6 engine]]s introduced in 2006.<ref name="findarticles.com">{{cite news| url=http://findarticles.com/p/articles/mi_m0KJI/is_10_115/ai_n6010896 | work=Automotive Design & Production | title=Ford's next step in engine manufacturing | first=Kermit | last=Whitfield | year=2003}}</ref> The Cyclone succeeds Ford's previous V6 engine families, including the Canadian [[Ford Essex V6 engine (Canadian)|built Ford Essex engine]] introduced in 1982, the [[Ford Vulcan engine]] introduced in 1985, the original [[Ford Duratec V6 engine|Duratec V6]] introduced in 1993, and the [[Ford Cologne V6 engine]], whose design dates back to 1962. The first version of the Cyclone engine, a 3.5&nbsp;L V6, appeared in the 2007 [[Ford Edge]] and the Lincoln-badged luxury variant, the [[Lincoln MKX]], as well as the [[Lincoln MKZ]]. [[Mazda]] badges its versions of the Cyclone '''MZI''' as it did with its versions of the ''Duratec V6''.

Although Ford continues using the Duratec name, the Cyclone shares no components or design with the previous Duratec and was entirely new.<ref name="Visnic">{{cite web|url=http://wardsauto.com/news-analysis/ford-motor-co-duratec-35-35l-dohc-v-6|title=Ford Motor Co. Duratec 35 3.5L DOHC V-6|last=Visnic|first=Bill|date=December 20, 2006|work=Wards Auto|access-date=25 March 2018}}</ref>

Notable Cyclone features include a capacity for displacements ranging up to 4.0&nbsp;L,<ref name="findarticles.com"/> DOHC 4-valve per cylinder heads, direct acting mechanical bucket (DAMB) camshaft tappets, [[variable valve timing|variable cam timing]] (iVCT) on the intake camshafts, and twin-independent variable cam timing (Ti-VCT) on some later versions. Features such as [[Gasoline direct injection]] and [[turbocharging]] were considerations in the design phase and have been added to the engine as part of '''EcoBoost'''. The 3.5&nbsp;L is [[Ultra Low Emission Vehicle|ULEV-II]] compliant and is capable of meeting the [[PZEV]] requirement.

== 3.3&nbsp;L ==
The ''Duratec 33'' {{cvt|3339|cc|L CID|1|disp=flip}} is a downsized version of Duratec 35 with both port and direct injection starting in 2018 model year for [[Ford F-150]], serving as the new base engine.

== 3.5&nbsp;L ==
The ''Duratec 35'' displaces {{cvt|3496|cc|L CID|1|disp=flip}} with a {{cvt|92.5x86.7|mm|in|2}} bore and stroke. Due to packaging differences in transverse (FWD) applications, the water pump is relocated to the valley behind the timing cover and is driven by the timing chain. The 3.5&nbsp;L engine will fit into any engine bay the smaller Duratec 3.0&nbsp;L will, and replaced it in some applications (notably the [[Ford Taurus]]) in the 2008 model year. Production began in 2006 for the [[Ford Edge]], [[Lincoln MKX]], and [[Lincoln MKZ]].

Official [[Horsepower#SAE certified power|SAE certified]] engine output is {{cvt|265|hp|kW|0}} and {{cvt|250|lbft|Nm|0}} on 87 octane gas. This is a substantial upgrade in power from the Duratec 30 and bested all comparable 87 octane rated V6 engines at the time of its launch.<ref>{{cite web|url=http://www.detnews.com/apps/pbcs.dll/article?AID=/20060412/AUTO01/604120342/1148|title=Ford's new V-6 catches up to competitors|work=[[Detroit News]]|access-date=April 12, 2006}}</ref> For 2011, the 3.5&nbsp;L received Ti-VCT, helping to boost output to {{cvt|285|hp|kW|0}} and {{cvt|253|lbft|Nm|0}}.<ref>{{cite web |url=http://media.ford.com/article_display.cfm?article_id=32009 |title=2011 FORD EDGE POWERTRAIN: MORE BITE, LESS HUNGER &#124; Ford Motor Company Newsroom |publisher=Media.ford.com |date=2010-08-16 |access-date=2012-01-24 |url-status=dead |archive-url=https://web.archive.org/web/20121004073912/http://media.ford.com/article_display.cfm?article_id=32009 |archive-date=2012-10-04 }}</ref> The 3.5&nbsp;L's highest output to date is {{cvt|290|bhp|kW PS|0}}. This version was used in the redesigned 2011 Ford Explorer.

The engine is assembled at [[Lima Engine]] in [[Lima, Ohio]], with expansion planned in [[Cleveland Engine|Cleveland Engine Plant #1]].

The 3.5&nbsp;L was on the [[Ward's 10 Best Engines]] list for 2007.

==EcoBoost==
{{main|Ford EcoBoost engine}}

It is a [[twin-turbo]]charged, [[gasoline direct injection|gasoline direct injected (GTDI)]] version of the 3.5&nbsp;L. This engine is used in the 2013-2019 Ford Explorer Sport, 2010-2019 Ford Taurus SHO, 2014-2019 Ford Flex Limited EcoBoost, 2010-2019 Lincoln MKT EcoBoost, and 2010-2016 Lincoln MKS, and is optional for both the 2014-2019 Ford Police Interceptor sedan and Ford Police Interceptor Utility, both of which are based on the Taurus and Explorer.

== 3.7&nbsp;L ==
The ''Duratec 37'' is a {{cvt|3726|cc|L CID|1|disp=flip}} version of the Cyclone V6 intended to power heavier or premium vehicles. The 3.7&nbsp;L's additional displacement comes from an increase in bore diameter to {{cvt|95.5|mm|in|2}}, stroke remains identical to the 3.5&nbsp;L at {{cvt|86.7|mm|in|2}}. Ford Power Products sells this engine as the '''CSG-637''' for industrial uses starting in mid-2015, which replaced the 4.2L Essex and is manufactured under license by Engine Distributors Inc.<ref>{{cite web |title=Ford Engines |url=https://www.edi-dist.com/ford-engines/ |website=Engine Distributors Inc. |access-date=15 August 2020 |date=5 December 2012}}</ref>

A [[Hiroshima]], [[Japan]] assembled Mazda MZI 3.7 was installed in the 2008 [[Mazda CX-9]] and was the first 3.7&nbsp;L Cyclone V6 to see production. The first Ford application of the 3.7&nbsp;L was the 2009 [[Lincoln MKS]].

A few days before the 2009 [[LA Auto Show|Los Angeles International Auto Show]], Ford unveiled a new version of the 3.7&nbsp;L for the 2011 Mustang, making it the first Duratec-badged V6 since the [[Lincoln LS]] to be used in a production rear-wheel drive car. Due to packaging differences in transverse applications, the water pump was relocated to the valley behind the timing cover and is driven by the timing chain. This version of the {{cvt|3726|cc|L|1|disp=flip}} features Twin Independent [[Variable Cam Timing]] (Ti-VCT); delivers {{cvt|31|mpgus|L/100 km mpgimp}} highway mileage in the Mustang, and was the first production engine to deliver in excess of {{cvt|300|hp|kW|0}} ''and'' {{cvt|30|mpgus|L/100 km mpgimp}}.<ref>{{cite web|url=http://media.ford.com/article_display.cfm?article_id=32160 |title=NEW MUSTANG V-6 WITH 305 HP CERTIFIED AT 31 MPG HIGHWAY; MAKES HISTORY AS FIRST CAR WITH 300+ HP AND 30+ MPG &#124; Ford Motor Company Newsroom |publisher=Media.ford.com |date=2010-03-04 |access-date=2012-01-24 |url-status=dead |archive-url=https://web.archive.org/web/20100716090619/http://media.ford.com/article_display.cfm?article_id=32160 |archive-date=2010-07-16 }}</ref>

===Water pump issues===
Water pumps on transversely mounted 3.5L V6, 3.5L EcoBoost V6, and 3.7L V6 engines have a tendency to fail and potentially ruin the engine when they do. The water pumps on these engines are internally mounted and driven by the timing chain. As a result, when they fail, antifreeze is dumped directly into the crankcase; mixing with engine oil and potentially damaging the head gaskets and connecting rod bearings. Many of these water pump failures occur without warning and repairs often cost thousands of dollars as the engine needs to be disassembled or removed from the vehicle to access the water pump. In some cases, the engine will need to be replaced outright. A class action lawsuit was started against Ford as a result of this issue, but it was dismissed and no recall was given. <ref>{{cite web|url=https://fordauthority.com/2019/08/ford-lawsuit-over-duratec-v6-due-to-water-pump/|title=Ford Lawsuit Over Duratec V6 Due To Water Pump|website=Ford Authority|access-date=February 17, 2021}}</ref>
All longitudinally mounted versions of the 3.3, 3.5, 3.5 EcoBoost, and 3.7 V6 use an external water pump.
