In 1977 I was at the Chrysler Proving Grounds in Chelsea, MI with what is now known as the Winged Warriors/ National B-Body Owners Association. We were gathered on the oval when the Chrysler exec who was hosting us directed our action up the track & urged us to be quiet. Suddenly a white sedan, a Coronet I think, “whooshed” past, only the noise of it cutting through the air giving a hint that it was there. I noticed there weren’t any turbine cars of that vintage on the above list, but it really seems that it was the ‘77 mid-size body. But that was a long time ago so maybe it was ‘73-74 style. But it was the current turbine technology that they were developing at the time.

Unfortunately, once it was gone, that was it, they didn’t display it for us to see.
