This is the 1984 Porsche 984 Prototype (BB-PW 984), an interesting project that simply got away, and could’ve found success in the market with its fuel efficient 2.0L turbocharged Type 4 F4 engine and lightweight design. The Porsche 984 Junior, commonly referred to simply as the 984, represents one of Porsche’s lesser-known experimental ventures into compact sports car design. Conceived in the mid-1980s, specifically between 1984 and 1987, this two-door roadster was envisioned as a lightweight, economical alternative to the brand’s more powerful offerings. Unlike the flagship models of the era, the 984 Junior aimed to deliver spirited driving dynamics while maintaining a lower production cost and improved fuel efficiency, drawing parallels to the Porsche 924 in concept but targeting a more accessible price point for a broader audience. The initial stages of the 984’s development were carried out in collaboration with the Spanish automaker SEAT, reflecting Porsche’s interest in pooling engineering expertise and market insights. Together, the collaboration gave rise to the unbuilt “Porsche PS,” for which a 1.5 L inline-four water-cooled engine called “System Porsche” was developed, later adopted by SEAT in the first-generation Ibiza. However, as the project progressed, Porsche opted to continue development independently, refining the 984 Junior’s engineering and aesthetic direction within its own design studios. By early 1988, Porsche formally terminated the project, citing a combination of financial considerations, market positioning concerns, and the company’s strategic focus on other models. Today, the 984 Junior remains a fascinating footnote in Porsche’s history. The 984 concept closely mirrored the Porsche-SEAT PS project, both aiming to be lightweight, enjoyable, and affordable sports cars, often using parts from contemporaneous Porsche models like the 924, 944, and 911.
