Why does the Audi A3 have a four ring logo?

I'm curious as to why the Audi A3 has a four ring logo. I've noticed all Audi models have this logo, but what does it represent?

The four ring logo on the Audi A3 represents the company's four founding companies: Audi, DKW, Horch, and Wanderer. It symbolizes the brand's rich history and heritage.

The four rings on the Audi A3 are a nod to the company's original logo, which featured four intertwined rings. This logo was used before the merger of the four companies and has become iconic for the brand.

In addition to representing the founding companies, the four ring logo on the Audi A3 also symbolizes the company's four core values: progress, beauty, sophistication, and precision.
