From John Gunnell’s book “75 Years of Pontiac Oakland“:
“Not content to leave pilot models as the were on his arrival, Bunkie Knudsen quickly effected the historic removal of “Silver Streak” hood bands and the addition of missle-shaped side trim panels. He then played a catalytic role in bringing heretofore experimental engineering directly to the assembly line. This was accomplished with the help of new key executives. In early September, 1956, Elliot M. “Pete” Estes replaced George Delaney as Pontiac chief engineer. Late the same month John Z. Delorean – recently of Studebaker-Packard – was appointed Director of Advanced Engineering.”
“General styling features of the 1957 models included the missle-side trim; flatter tail fins; lower hood lines; more massive bumper-grille arrangement; lower horizontal taillights and smaller 14 inch wheels.”
334, 041 units were built.
