Cadillac design and engineering teams, who continue to develop CELESTIQ as it moves closer to production have studied “the artisanship and customization that defined early Cadillac sedans such as the bespoke V-16 powered coaches of the prewar era, and the hand-built 1957 Eldorado Brougham. The CELESTIQ is the culmination of that heritage, brought to life with innovative production methods and new technologies,” Cadillac said in a release.
