Mays moved back to the United States in 1989, to become chief designer at the Volkswagen of America Design Center in Simi Valley, California. While there, he collaborated with Thomas on the design of the Volkswagen Concept 1 concept car, a modern re-interpretation of the original Volkswagen Beetle. This was first shown at the 1994 North American International Auto Show, and the positive response led to the car entering production as the Volkswagen New Beetle.
