The Firebird
The Firebird IV debuted at the 1964 New York World's Fair, in the General Motors Futurama Exhibit. It was another sleek, aircraft-inspired, turbine-engined "future" design, which GM coded internally as the XP-790. Its designers conceived it for a future in which cars steered automatically via programmed guidance systems, to "ensure absolute safety at more than twice the speed possible on expressways of the day." Though billed as being turbine-powered, the Firebird IV was non-functional. GM repackaged the Firebird IV for the 1969 show circuit as the Buick Century Cruiser. Reportedly, the show car was crushed in the 1980s.
