Editing V-twin engine (section)

==Automobiles==
Most cars are powered by engines with three or more cylinders, however several small cars have been produced with V-twin engines particularly during the period from 1912 to 1920 when [[cyclecar]]s were made by many companies (due to a favourable tax position). Almost all of these used proprietary engines, either adapting the larger motorcycle engines used for sidecar work (large singles or V-twins), or using engines specifically made for cyclecars such as those made by [[J. A. Prestwich Industries]] ('J.A.P.' engines) or [[F. E. Baker Ltd]] ('Precision' engines).

In 1912, Humber produced a light car called the Humberette with a Humber-made V-twin side-valve engine of 998cc. The engine had a directly attached clutch, 3-speed gearbox and prop shaft output to a rear differential. A water cooled version of this engine was made available in 1914, but WW1 ended Humberette production in 1915.<ref>{{cite magazine |last= |first= |date=26 October 1912 |title=The Humberette |url= |magazine=The Auto Motor Journal |publisher= |page=1244}}</ref>

From 1911 to 1939, various [[Morgan Motor Company#V-Twin three-wheelers (1911–1939)|Morgan 3-wheelers]] three-wheeled [[cyclecar]] models were powered by V-twin engines. Production of three-wheeler models then resumed with the 2012–present [[Morgan 3-Wheeler]]. Also in the United Kingdom, [[Birmingham Small Arms Company]] (BSA) produced several cars powered by their V-twin motorcycle engines. These were produced from 1921 to 1926 (four-wheel models) and 1929–1936 (three-wheel and four-wheel models).<ref>{{cite book | title= Three Wheelers - Those were the days | first= Malcolm | last= Bobbitt | publisher= Veloce Publishing Ltd | year= 2004 | page= 16 | isbn= 978-1-903706-81-7}}</ref>

Several manufacturers have produced models inspired by the original Morgan three-wheeled car, such as the 1978–present [[Triking|Triking Cyclecar]] (using a Moto Guzzi engine),<ref>{{cite web| title = Triking| url = http://www.3wheelers.com/triking.html| work = 3wheelers.com| access-date = 2010-08-21| url-status = live| archive-url = https://web.archive.org/web/20101005102736/http://3wheelers.com/triking.html| archive-date = 2010-10-05}}</ref> the 2006–present Ace Cycle Car (using a Harley-Davidson engine)<ref>{{cite web| title = Ace Cycle Car| url = http://www.cycle-car.com| access-date = 2008-11-27| url-status = live| archive-url = https://web.archive.org/web/20081210235648/http://cycle-car.com/| archive-date = 2008-12-10}}</ref> and the 1990–present [[JZR Trikes]] kit car (using engines from several manufacturers).<ref>{{cite web| title = JZR Vehicles| url = http://www.3wheelers.com/jzr.html| work = 3wheelers.com| access-date = 2010-09-10| url-status = live| archive-url = https://web.archive.org/web/20101005101746/http://3wheelers.com/jzr.html| archive-date = 2010-10-05}}</ref>

Mazda's first car, the 1960–1966 [[Mazda R360]] rear-engined [[kei car]], was powered by the {{convert|356|cc|cuin|1|abbr=on}} [[Mazda V-twin engine]].<ref>{{cite web| last = Adolphus | first = David Traver | title = Hemmings Motor News: 1964 Mazda R360| url = http://www.hemmings.com/hsx/stories/2007/07/01/hmn_feature20.html| work = Hemmings Motor News| access-date = 2010-08-21|archive-url=https://web.archive.org/web/20120711063354/http://www.hemmings.com/hsx/stories/2007/07/01/hmn_feature20.html|archive-date=2012-07-11|url-status=live}}</ref><ref>{{cite web| title = 1962 Mazda R-360 Coupe "De Luxe"| url = http://microcarmuseum.com/tour/mazda-r360.html| work = The Bruce Weiner Microcar Museum| access-date = 2010-08-21| url-status = live| archive-url = https://web.archive.org/web/20100924173219/http://microcarmuseum.com/tour/mazda-r360.html| archive-date = 2010-09-24}}</ref> The 1961–1962 [[Mazda Porter#B360/B600|Mazda B360]] front-engined light commercial vehicle used a {{convert|577|cc|cuin|1|abbr=on}} version of this engine.
