Carving out a piece of history. Here's something that's seldom seen by those outside of a manufacturer. Here the designers at Dodge are working with the original clay model for the '70 Challenger. Clay models are a clever way for designers to see how their ideas transfer from paper into a three-dimensional 1:1 scale car. Notice the distinct side character line, which made the final design, and the multiple front and rear designs. This press photo was not to be released to the public until after Wednesday, August 27, 1969. Better late than never! Photo Courtesy of the Chrysler Group Archives
