Plastic outer panels made Fiero styling easy and inexpensive to change, but the "driveable space frame" made additional body styles rather more difficult and costly than conventional construction. Even so, Pontiac devised a racy Fiero- based speedster in mid-1983, then updated its styling a year later. The handsome red job seen here was built around 1986, with that year's GT coupe lower-body styling, to investigate the feasibility of a convertible Fiero. Besides a fully engineered soft top with modest "stack height," this prototype boasted a left-hinged rear deck that swung up sideways for engine access. But cost factors made production unlikely even if Fiero had continued past 1988.
