Audi is one of Germany’s oldest automobile manufacturers. Since 1932, Audi has used the four-ring emblem, which symbolizes the Auto Union formed by the merger of Audi, DKW, Horch, and Wanderer.

In the 1930s, the Auto Union covered every segment of the passenger car market that the German automotive industry had to offer, ranging from motorcycles to luxury sedans.

In 2008, Audi was ranked seventh on the “Top Brands in China for Buyer Satisfaction” list compiled by the World Brand Value Lab.

The Audi logo features four interlocking rings, representing the four companies that merged to form the brand.

These companies were formerly manufacturers of bicycles, motorcycles, and light commercial vehicles. Since the company was formed by the merger of four firms, each ring symbolizes one of the original companies.
