1. Cadillac Cyclone (1959)
It’s not hard to see the inspiration for this shiny, bubble-canopied “dream car,” which looks like it was designed to fly through the air rather than chew up the road. Dubbed the Cadillac Cyclone, the prototype was again spawned by Harley Earl, this time working with designers Carl Renner and Bill Mitchell. Launched in 1959 at the first ever Daytona 500 in Florida, Earl planned the futuristic car as his grand swan song to automotive design. Codenamed XP-74, the Cyclone featured a UV ray-repeling vaporized silver finish, a powered foldaway flip-top bubble canopy, external speakers, button-operated retracting doors and radars in its front fenders, intended to communicate with “smart roads” of the future. Revised several times, the Cadillac Cyclone was popular on the show circuit until its eventual retirement.
