Cadillac Cyclone

The Cadillac Cyclone was a concept car built by Cadillac in 1959 as a testbed for futuristic styling and technology, and it was never put into mass production. It was one of the last cars designed by Harley Earl, and its look drew on the aviation and rocket designs of the 1950s. It rode on a 104 inch wheelbase chassis with a front-mounted 390 cubic inch engine, a rear-mounted automatic transaxle and all-wheel independent suspension, with the exhaust ported out just ahead of the front wheels. Its most prominent feature was a silver-coated bubble top canopy that opened automatically along with the sliding electric doors, and twin nose-cones on the front housed the sensors of a radar-operated collision avoidance system. The tailfins were reduced in size in 1964 to match the 1963 and 1964 Cadillac range. The car is kept in the GM Heritage Collection.
