PART I of this paper describes the basic research and experimental development program of the air-spring suspension, Part II details the application of the principle to the 1957 Cadillac Eldorado Brougham.
The authors think that the final design successfully met the development program criteria of cost, size, life, adaptability, and rate characteristics. This design, in turn, offered the features of constant height, smoother ride, and better handling, which appealed to the design engineers working on the Cadillac.
