MAZDA AND ITS subsidiary, Autozam, put a lot of effort into getting the design just right. So much so that it displayed three AZ550 concepts at the 1989 Tokyo auto show and asked the public for feedback. Type A most closely resembles the production car, with a change from retractable to fixed headlights to lower cost and improve structural rigidity.
Type B featured conventional doors, vertical headlights, and bulbous fenders, and Type C appeared as a Group C endurance racing prototype with a bubble-style canopy and racy rear wing. Type C was actually the most popular with the public, but Mazda officials decided Type A was the most viable.
