Thomas, the son of an American military air traffic controller and a German mother, traveled frequently around Europe during his childhood. This led to an early awareness of cars - in his own words, "a certain sense of automotive space."
After leaving Porsche, he worked in consultancy, journalism and teaching, before joining Volkswagen of America in 1991.
While at the Volkswagen Design Center in Simi Valley, California, he collaborated with fellow Art Center graduate J Mays 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 (NAIAS), and the positive response led to the car entering production as the Volkswagen New Beetle. In 1994, he began the design of the acclaimed Audi TT concept car, which also led to a production model.
In 1999, Thomas was appointed vice president of DaimlerChrysler Advanced Product Design Strategy, later beconing head of their Pacifica Advanced Design Center in 2002. At DaimlerChrysler he oversaw the design of several Chrysler, Dodge and Jeep concept cars and production models.
Thomas moved to the Ford Motor Company, taking up the role of Director, Strategic Design for North America on 1 June 2005. He is responsible for developing product design strategies and concept vehicles for the Ford (inclusive of the current Mustang design), Lincoln and Mercury marques.
Cris Huergas and Freeman Thomas of California founded R Gruppe, an early 911 Porsche sports club on May 15, 1999. They did so with the intention of bringing like-minded individual together to share technical and historical information related to their cars, as well as sharing views and ideas concerning the ownership, preparation, maintenance and operation of their cars.
