1985 Pontiac Trans Am Experimental

The Kammback concept, a body style that was similar to a station-wagon, supposedly originated in Europe. They had a squared-off back end that performed well in wind-tunnel testing, providing functional airflow efficiency for reduced drag. This translated into higher speeds and better fuel economy at highway speeds. The design almost made it into production for the 1970 Firebird and Camaro. Though the design did not make it into production, the idea remained with the GM Tech Center design and engineering circles for many years. In 1979, a Trans Am show car version appeared, followed by two experimental 1985 Trans Am Kammbacks that even made it onto the cover of Motor Trend.

The squared-off Kammback design was bolted right on in place of the all-glass hatchback of the production Trans Am, including the latching. The idea remained a concept and never made it into production.

This example was a test mule for some time before being recruited for special body treatment by GM designers. It was later stored at GM for 13 years until a local Pontiac dealer and collector was able to acquire it. It is equipped with the 190 horsepower, 305 cubic-inch HO (high output) V8 option, and a four-speed manual transmission.

Most GM experimental cars were doomed to meet the crusher, but luckily some escaped.
