New to the 1957 Cadillac Biarritz

Cadillac’s were redesigned for 1957 and went through a complete retooling for the  model year. The Eldorado Biarritz styling was inspired by Motorama show cars.

Innovations included an unusual tubular X-frame, without side rails. This new design gave the car greater rigidity and increased length and wheelbase. A curved wraparound windshield added style. .The body was three inches” lower to the ground but at the expense of side impact protection.

The optional air ride suspension gave the car a luxurious ride when it worked, which was at best sporadically. Most buyers did not take this option and many of those who didn’t chose to ultimately change to traditional springs. If not the car had the tendency  to list, sag and drag. This suspension situation was certainly not up to the engineering standards Cadillac customers came to expect.

General Motors tail fin designs, and Cadillac was probably one of it’s best examples,  can be attributed to one very well known automotive designer. Legendary General Motors head designer Harley Earl absolutely loved big tail fins.The inspiration for tail fins on automobiles came from the aircraft of the 1940’s.The story is that Earl was impressed with the Lockheed twin tail P-38 fighter from World War Two and the rest  is history.
