# Ford Cyclone engine

The Ford Cyclone is a family of aluminum 60-degree DOHC V6 gasoline engines produced by [Ford Motor Company](https://www.edgepedia.org/ford-motor-company) from 2006 onward, sold as the Duratec 33, Duratec 35, and Duratec 37 in naturally aspirated form and as the basis for the 2.7 L, 3.0 L, and 3.5 L EcoBoost turbocharged V6s.<sup>[1](https://baraanduliaptti.org/userfiles/file/badeto.pdf)</sup> The family was code named "Cyclone" during development.<sup>[2](https://www-performanceparts.app.ford.com/download/pdfs/EngineHistory.pdf)</sup>

## Design

The Cyclone engines are all-aluminum 60-degree V6s with double overhead camshafts and four valves per cylinder.<sup>[1](https://baraanduliaptti.org/userfiles/file/badeto.pdf)</sup><sup> • </sup><sup>[2](https://www-performanceparts.app.ford.com/download/pdfs/EngineHistory.pdf)</sup>

The naturally aspirated versions use Ti-VCT, twin independent variable camshaft timing, which controls valve opening on each camshaft independently to improve engine breathing; Ford already used the technology on European engines such as the 1.6 Ti-VCT in the [Ford Focus](https://www.edgepedia.org/ford-focus).<sup>[4](https://www.youtube.com/watch?v=F0w73RTiEHo)</sup> The Mustang's 3.7 has an aluminum block with low-friction components and, unlike the EcoBoost variants, no direct injection; it is naturally aspirated.<sup>[4](https://www.youtube.com/watch?v=F0w73RTiEHo)</sup>

## Applications

**Crossovers and sedans.** The family entered service in 2006, when 3.5-liter Cyclone engines appeared in the [Ford Edge](https://www.edgepedia.org/ford-edge) and [Lincoln MKX](https://www.edgepedia.org/lincoln-mkx) crossovers.<sup>[3](https://otoba.ru/dvigatel/ford/cyclone.html)</sup> The first 3.7-liter engine produced was the Mazda MZI 3.7, assembled in [Hiroshima](https://www.edgepedia.org/hiroshima), Japan, and installed in the 2008 Mazda CX-9; Ford's own first 3.7 L application was the 2009 Lincoln MKS.<sup>[10](https://fordauthority.com/fmc/ford-motor-company-engines/ford-cyclone-engine-family/ford-3-7l-duratec-37-engine/)</sup> The 3.7 was also used in the fifth-generation Ford Explorer.<sup>[8](https://www.diyauto.com/engines/3-7l-cyclone-v6)</sup>

**Mustang.** For the 2011 model year the 3.7 became the Mustang's all-new base motor, replacing the 4.0-liter six that dated back more than four decades.<sup>[6](https://www.motortrend.com/reviews/2011-ford-mustang-v-6-test)</sup> In S197 form it produced 305 hp and 379 Nm (280 lb-ft) at 4,250 rpm.<sup>[4](https://www.youtube.com/watch?v=F0w73RTiEHo)</sup> The 2015 S550 Mustang carried a factory SAE net rating of 300 hp at 6,500 rpm and 280 lb-ft at 4,000 rpm.<sup>[5](https://www.worldsbestoil.ca/cross-reference/engines/ford/3700-cyclone-v6/)</sup> Ford targeted 30 mpg highway (7.84 L/100 km) with the six-speed automatic, which consumed slightly less than the six-speed manual at 8.11 L/100 km.<sup>[4](https://www.youtube.com/watch?v=F0w73RTiEHo)</sup> The V6 remained the entry Mustang through the 2017 selling season and was then dropped from the lineup.<sup>[7](https://www.caranddriver.com/reviews/a15092871/2017-ford-mustang-coupe-and-convertible-review/)</sup>

## EcoBoost derivatives

The Cyclone architecture also underlies Ford's turbocharged EcoBoost V6s: the 3.5 L EcoBoost from 2009, the 2.7 L EcoBoost from 2015, and the 3.0 L EcoBoost from 2016.<sup>[1](https://baraanduliaptti.org/userfiles/file/badeto.pdf)</sup> Ford's own service literature lists the 3.5 L V6 EcoBoost alongside the 3.7 V6 in the same vehicle engine lineups.<sup>[9](https://www.fordservicecontent.com/Ford_Content/vdirsnet/OwnerManual/Home/Content?ProcUid=G1609288&Uid=G1604186&buildtype=web&countryCode=USA&div=f&languageCode=en&userMarket=usa&vFilteringEnabled=False&variantid=2999)</sup>
