They needed versions of the logo in low-color for window decals, but also needed the design to be translatable to full-color for hard copy, T-Shirt embroidery, etc. I wanted to incorporate their acronym with the Audi rings logo. Since they are a sport-driving-based group I also wanted to incorporate the Audi Sport "red slash".
I went through a round of designs and they had their pick.
The final 1-color design.
The final 2-color design.
The final full-color design.
