Auto Union
The current corporate entity which bears the Auto Union name – "Auto Union GmbH" – was founded in 1985 and is a wholly owned subsidiary of Audi AG; its purpose is to act as owner of Auto Union's historical trademarks and intellectual property, as well as managing Audi's heritage operations. The company's distinctive logo, of four interlocking rings to represent the original four members of the Auto Union, survives as the logo of Audi.
