Audi AG is a German automobile manufacturer with headquarters in Ingolstadt, Bavaria, and has been an almost wholly owned (99.7%) subsidiary of the Volkswagen Group since 1964. The company evolved from both Auto Union and NSU, the former having incorporated the historic Audi company which was originally founded in 1910.
