01 / THE STORY

History & context

The Fiat 850 Weekend OSI, an intriguing and rare “spiaggina” (beach car), was unveiled at the 1967 Turin Auto Show. This unique vehicle was the result of a collaboration between Fiat and OSI, a Turin-based coachbuilding company. OSI, founded in 1960, was known for producing limited-edition or custom-bodied vehicles, often based on existing Fiat models. The 850 Weekend OSI stands out as one of the most distinctive creations from their portfolio. Designed by Sergio Sartorelli, an accomplished automotive designer also responsible for the Fiat 850 Coupe and other notable vehicles, the Weekend OSI offered a fresh take on the “spiagginaspiaggina” concept. This category of car was primarily aimed at leisure use in sunny, coastal regions, often favored by affluent buyers seeking stylish, open-air transportation. The Fiat 850 Weekend OSI embodied this ethos with its compact size, quirky design elements, and open architecture. The vehicle was based on the Fiat 850 platform, a versatile and popular rear-engine, rear-wheel-drive chassis. While the 850 itself was a practical and widely sold small car, the OSI interpretation transformed it into something far more exclusive. The Weekend OSI featured a stripped-down, open-body design with minimal doors, exposed wheels, and a lightweight structure, prioritizing fun and utility over conventional comfort. Its aesthetic was highly appealing, with a charming yet functional design that captured the carefree spirit of the 1960s. The Fiat 850 Weekend OSI was produced in extremely limited numbers, making it a highly sought-after collector’s item today. Its rarity can be attributed to OSI’s boutique manufacturing capabilities and the niche market for such vehicles. Despite its limited production, the car remains an iconic example of Italian automotive creativity during the 1960s. The Fiat 850 Weekend OSI holds a special place in automotive history, combining innovative design by Sartorelli with OSI’s craftsmanship to create a car that perfectly encapsulates the era’s casual elegance and adventurous spirit.
