The O-480 began as a six-cylinder version of the company's four-cylinder O-320. Its main installations have been in the larger Beech twin-engined aircraft (notably the Queen Air and Model 50 Twin Bonanza) and in some manufactured by Piaggio in Italy. The company which manufactures the O-480 has gone by a sequence of names, initially using the Lycoming name when it directed its efforts towards car manufacture in 1907.

Its first aircraft engine, the R-680, was first produced in 1929. The name "AVCO Lycoming" was adopted in 1939, and the name remained until 1986, when the company was taken over by Textron, and became Textron Lycoming. From 1994 to 1999 it was sold, and merged with the Garrett turbine engine manufacturer, then with Honeywell Aerospace. However, the Lycoming Engines name has been retained.
