Cadillac Cyclone

[1] One of the last cars designed by Harley Earl, the Cyclone was a testbed for futuristic styling and technology.

Built on a 104" wheelbase chassis, it featured a front-mounted 390in3 engine, rear-mounted automatic transaxle, and an all-wheel independent suspension.

It also featured a radar-operated collision avoidance system, with the radar sensors mounted in twin "nose-cones" on the front of the car.

Silver coated for UV protection, the canopy automatically opened along with the sliding electrically operated doors.

The original design of the Cyclone included larger tailfins (similar looking to the 1959 Cadillac lineup), adorned with the logo of the General Motors Air Transport Section (GMATS).
