What was Audi's official company name from 1969 until 1985?

Audi’s official company name from 1969 until 1985 was Audi NSU Auto Union AG.

The name was created when Auto Union GmbH merged with NSU Motorenwerke AG in 1969. It deliberately preserved both historic identities: Auto Union represented the four-ring heritage and Audi marque, while NSU was a major Neckarsulm-based manufacturer known for innovative cars and motorcycles.

The merger took effect retroactively from 1 January 1969. The combined company operated plants in both Ingolstadt and Neckarsulm, and Volkswagen became the controlling force behind its development. The long corporate name appeared during a transitional period when the company was consolidating several brands and engineering traditions.

On 1 January 1985, the company changed its name to Audi AG and moved its headquarters from Neckarsulm to Ingolstadt. The NSU name then disappeared from the corporate title, although its technical and manufacturing legacy continued. Volkswagen Audi AG is a later-sounding but incorrect answer for this period.
