This is why the Audi logo has four rings
Regarding old businesses, rebranding is critical to keep up with current times. Audi’s logo has also evolved significantly during its decades of operation. Four interlocking rings symbolized the merging of four vehicle manufacturers in the German state of Saxony: Audi, DKW, Horch, and Wanderer became Auto Union AG.
The first design, created in 1909, was relatively simple, yet it does not resemble a car logo. The new design, which consists of four rings, is far more appealing and easy to distinguish. The designers thought the logo had to look stylish both on paper and online. As a result, the four rings became two-dimensional in 2016.
