Here’s a treat: rare General Motors footage of the experimental Cadillac Interceptor going through its paces at the Milford Proving Grounds. Check it out.
This little clip illustrates a common practice in the Motor City car biz even today. Competitive analysis, it is sometimes called. Here, four cars are filmed and compared in a naturalistic setting: a ’48 Cadillac Series 62 Sedan, a ’46-’47 Cadillac 62 Sedan, a ’48 Hudson Commodore, and surprise. The fourth car in the group is the near-mythical Cadillac Interceptor prototype, also known as the Cadillac C.O. Two Interceptor experimental mules were reportedly constructed in 1946-47, both of which were destroyed once testing was completed.
The Interceptor concept, finless and bullet-shaped with hidden headlights, was eventually shelved in favor of the tail-finned design theme that became the production 1948 Cadillac. It’s fun to see the two models together here at what appears to be the General Motors Proving Grounds in Milford, MIchigan. Watch.
