Among the first cars to use a straight-three engine is the 1953–1955 [[DKW#Automobiles made after 1945|DKW F91]], powered by a {{convert|900|cc|cuin|0|abbr=on}} [[two-stroke engine]], although this was predated by the 3 cylinder 15hp Rolls Royce produced in 1905 and a number of other cars of this era also used 3 cylinder engines.  The 1956–1960 [[Saab 93]] saw the introduction of Saab's {{convert|750|cc|cuin|0|abbr=on}} two-stroke engine, which was also used in the [[Saab 95]], [[Saab 96]] and [[Saab Sonett]] until 1968 after which it was replaced by the [[Ford Taunus V4 engine]].

The [[Wartburg (car)|Wartburg]] cars (manufactured in East Germany) and [[FSO Syrena]] (manufactured in Poland) also used straight-three engines.

The 1967 [[Suzuki Fronte#Fronte 360|Suzuki Fronte 360]] uses a {{convert|256|cc|0|abbr=on}} two-stroke engine. In 1980, Suzuki began production of a {{convert|543|cc|0|abbr=on}} four-stroke engine, which was introduced in the Alto and Fronte models.

The [[Subaru EF engine]] is a 4-stroke petrol engine which was introduced in 1984 and used in the [[Subaru Justy|Justy]]<ref name="RnT3x3July93" /> and the [[Subaru Sumo|Sumo]] (the export version of the Sambar).

The straight-three versions of the [[Ford EcoBoost engine]] – a turbocharged 1.0-litre petrol engine – was introduced in the 2012 Ford Focus.<ref>{{cite web |url=https://social.ford.com/en_US/story/sustainability/green/smallest-ford-engine-ever-three-cylinder-ecoboost-and-two-new-transmissions.html |title=Smallest Ford Engine Ever! Three-Cylinder EcoBoost (and Two New Transmissions) |access-date=2017-04-03}}</ref> It uses an unbalanced flywheel to shift the inherent three-cylinder imbalance to the horizontal plane where it is more easily managed by engine mounts, and so remove the need to use balance shafts.<ref>{{cite web|url=http://wardsauto.com/technology/ford-s-3-cyl-ecoboost-delivers-goods |title=Ford's 3-cyl. EcoBoost Delivers the Goods |date=2014-05-15 |access-date=2017-04-03}}</ref> In 2016, [[cylinder deactivation]] was added, claimed to be a world first for three-cylinder engines.<ref>{{cite web|url=https://media.ford.com/content/fordmedia/feu/en/news/2016/11/29/ford-to-offer-fuel-saving-cylinder-deactivation-tech-for-1-0-lit.html |title=Ford To Offer Fuel-Saving Cylinder Deactivation Tech FOR 1.0 Litre EcoBoost; Global First For A 3-Cylinder Engine |date=2016-11-29 |access-date=2017-04-03}}</ref>
