Straight-eight engines were used in expensive luxury and performance vehicles until after World War II. [[Bugatti]]s and Duesenbergs commonly used [[DOHC|double overhead cam]] straight-eight engines. Other notable straight-eight-powered automobiles were built by [[Daimler Straight-Eight engines|Daimler]], [[Mercedes-Benz]], [[Isotta Fraschini]], [[Alfa Romeo]], [[Stutz Motor Company|Stutz]], [[Stearns-Knight]] and [[Packard]]. One marketing feature of these engines was their impressive length — some of the Duesenberg engines were over {{convert|4|ft|m|1|abbr=on}} long, resulting in the long hoods (bonnets) found on these automobiles.
