Juliane and Nadya Arnaout worked together to design the BMW's latest Z4 roadster. Juliane designed the exterior and Nadya handled the interior. The two initially met while working for BMW Designworks in California. Both decided to enter the internal contest with their ideas and won.
Juliane said she attempted to design the Z4 roadster using an athlete's body as her inspiration. She didn't think whether it was male or female, she just wanted to get the contours and sense of strength.
