The IOE valvetrain layout was used extensively in early American motorcycles, mainly based on a French design by De Dion-Bouton. Harley-Davidson used IOE engines with atmospheric inlet valves until 1912, and with mechanically driven inlet valves from 1911 to 1929. Indian used IOE valvetrains on all of their four cylinder bikes except those built in 1936 and 1937. Other American motorcycle manufacturers that used IOE engines included Excelsior, Henderson, and Ace.

Hudson used an IOE inline-four engine in its Essex line of cars from 1919 to 1923 and an IOE straight-six engine in its Hudson line of cars from 1927 to 1929. Willys, and its successor Kaiser-Jeep, used variants of the Willys Hurricane engine from 1950 to 1971.
Rolls-Royce used variants of their B60 IOE straight-six engine in their Wraith and Silver Wraith cars. A short-stroke oversquare version of the B60 engine was also used in the Princess 4-litre-R saloon car, displacing 3909cc and producing around 175 hp (manufacturers figures). This was known as the FB60 and was substantially upgraded from the common-or-garden B60 - it had hydraulic lifters, different carburation, hotter cam and other improvements. These changes liberated a 55 hp increase from the B60 engines' 120 hp output. Over 6000 of these cars were made.
