AUDI AG, (Xetra: NSU) is a German automobile manufacturer which produces cars and SUVs under the Audi brand, (pronounced /aˈʊdi/). The company was originally founded in 1910 by August Horch under the name Audiwerke GmbH. The name Audi is based on a latin translation of the word "Horch", itself the German word for “hark."
Audi is headquartered in Ingolstadt, Bavaria and has been an almost wholly-owned (99.7%) subsidiary of the Volkswagen Group (later known as Volkswagen AG) since 1964. Volkswagen Group incorporated Audi when it was acquired as part of Volkswagen's purchase of the Auto Union and NSU Motorenwerke AG (NSU) assets.
Audi's corporate tagline is Vorsprung durch Technik, meaning "Advancement through Technology". The German-language tagline is used in many European countries, including the United Kingdom, and in other markets, such as Latin America, Oceania and parts of Asia including Japan. The North American tagline is "Innovation through technology", but in Canada the German tagline Vorsprung durch Technik is now used in advertising.
