Pontiac Firebird Trans Am Experimental Kammback

This experimental 1985 Trans Am with its “Kammback” rear section is a genuine former General Motors test platform, equipped with the 190 hp, 305 cubic inch HO (high output) V8 option and a four-speed manual transmission. The car was used as a test mule for some time before being recruited for special body treatment by GM designers.

The station-wagon-like Kammback concept supposedly originated in Europe and almost made it into production for the 1970 Firebird and Camaro. The squared-off back end actually performs well in wind-tunnel tests, providing functional airflow efficiency for reduced drag, translating into higher speed or better fuel economy at highway speeds. And, had it ever become available to the public, an American Kammback would have been quite distinctive from other cars on the road. While not adopted for 1970, the idea stayed around GM Tech Center design and engineering circles, with a 1979 Trans Am version being crafted as a show car. Two experimental ‘85 Trans Am Kammbacks were even featured on the cover of Motor Trend.

This car was auctioned off by RM Auctions in March of 2010 at the Ritz-Carlton, Amelia Island, Florida.

190 hp, 305 cu. in. G-Code HO overhead-valve V8 engine, four-speed manual transmission, torque arm/track bar with coil springs and anti-sway bar, ventilated front disc and rear drum brakes. Wheelbase: 101"
