In 1946, Cadillac’s Interceptor concept was a design without tail fins

Car reached prototype testing stage but the fin was in


Thanks to Bill McGuire at Mac’s Motor City Garage for tipping us off to the Video of the Day, which shows the 1946 Cadillac Interceptor concept car/prototype undergoing testing at GM’s Milford Proving Grounds in Michigan.

There’s no vocal with the 3-minute video, but the images show four cars on the test track, including a 1946 Cadillac Series 62 sedan, a 1948 Cadillac Series 62 sedan, a 1948 Hudson Commodore and the Interceptor. 

Apparently, Cadillac built a pair of Interceptor prototypes, and consumed one as a crash-test vehicle. The other reportedly was destroyed after its time on the test track.

Mac notes that the Interceptor had suicide doors and a two-piece wraparound windshield, and what about that long and low tail section?
