The 1959 Cadillac Cyclone concept featured what innovative safety system?

The 1959 Cadillac Cyclone concept featured a radar-operated collision-avoidance system. Radar sensors were mounted in twin nose-cones at the front of the car, allowing the futuristic Cadillac to demonstrate an early form of electronic crash detection.

The Cyclone was one of Harley Earl’s final designs and combined space-age styling with experimental technology. Its aviation- and rocket-inspired body included a silver-coated bubble canopy, electrically operated sliding doors, and prominent tailfins. The canopy could open automatically with the doors and was designed to reduce ultraviolet exposure.

The radar system was not the same as modern adaptive cruise control or autonomous emergency braking. It was an experimental safety feature built into a one-off concept car, not a production system offered to ordinary Cadillac buyers. The Cyclone itself was never mass-produced and is now part of the GM Heritage Collection. Its unusual technology is why it is frequently cited as an early automotive crash-avoidance experiment.
