W12 engines with three banks of four cylinders were used by several aircraft engines from 1917 until the 1930s. A three-bank W12 design was also used unsuccessfully by the [[Life Racing Engines|Life F1 team]] in the [[1990 Formula One World Championship|1990 Formula One season]], failing to qualify at every race.<ref>{{Cite book|title=The V12 Engine|last=Ludvigsen|first=Karl|publisher=Haynes|location=Sparkford, Yeovil|year=2005|isbn=1844250040|ref={{harvid|Ludvigsen|V12 Engine}}|pages=356–358}}</ref>

Although less commonly used in automobiles than V12 engines, a W12 petrol engine has been produced by the [[Volkswagen Group]] starting in 2001. This four-bank engine—based on two [[VR6 engine]]s with a common crankshaft—has been used in various cars sold under the Audi, Bentley and Volkswagen brands and has appeared in multiple variants, including a rare 6.3L normally aspirated version only available in the D4 [[Audi A8]] L. In 2018 the Volkswagen Group announced the W12 engine would be exclusive to vehicles produced by their [[Bentley]] divison<ref>{{Cite web|url=https://www.autoblog.com/2018/03/19/audi-a8-w12-engine/|title=A8 is the last Audi to get the W12 engine, exclusive of Bentley|website=Autoblog|date=19 March 2018 }}</ref>
