Why does the Audi A6 have a four-ring logo?

I've noticed that all Audi models have the four-ring logo, but I'm wondering why specifically the A6 has it.

The four rings in the Audi logo represent the four companies that merged to create Audi: Audi, DKW, Horch, and Wanderer. These companies had a strong presence in the automotive industry in the early 20th century, and combining their strengths allowed Audi to become a successful brand.

The Audi A6 is a luxury sedan that exudes elegance and sophistication. The four-ring logo symbolizes this, as it represents the car's high quality and premium status in the automotive market. Plus, it looks pretty cool too.
