From Wikipedia

The two-seater arrived in 2001 as a concept car designed by Eric Stoddard[3] with further refinement by Andrew Dyson[4] before beginning production in 2003.

My question is were they part of the US Design Team?

EDIT:
While at the Chrysler Headquarters and Technology Center in Auburn Hills, Michigan, Eric worked under Don Renkert to design the Chrysler Crossfire Concept [1][2] released at the North American International Auto Show in 2001. Eric went on to become the lead exterior designer of the production model of the Chrysler Crossfire under Andrew Dyson[3].
Eric was also the lead exterior designer on the Dodge SRT-4 as well as a contributing designer to the Chrysler Pacifica, 2003 Dodge Viper and Chrysler Sebring.
