Concept Car of the Week: Cadillac Voyage (1988)

Once a symbol of America's most luxurious automobiles, Cadillac's image had begun to wane by the mid-1980s, and not even the Pininfarina-designed and built two-seater Allante was enough to excavate the brand's long gone leadership. In an effort to take Cadillac onto the global stage, engineers and the team of designers led by Chuck Jordan began working on the Voyage concept, a rolling laboratory with visionary styling and innovative technology. It was unveiled in 1988 at a technological exhibition in New York thus highlighting that rather than a stylist's dream come true, it was a very serious study towards aerodynamic, performance, handling, comfort and efficiency in an age when automated superhighways would allow fast, safe inter-State travel.
