01 / THE STORY
History & context
The Osi 20M TS Spider is a fascinating piece of automotive history, representing a rare and ambitious endeavor by the Italian coachbuilder Osi. As the convertible variant of the OSI 20M TS Coupé, the Spider showcased a blend of sporty performance and elegant design, although it remained a prototype rather than reaching full production. Introduced in 1967, the Osi 20M TS Spider was built on a chassis that was 200mm shorter than that of its coupé counterpart. This modification resulted in a more compact and agile vehicle, enhancing its sporty character while maintaining the graceful lines that defined the 20M TS Coupé. The Spider’s design was an evolution of the coupé’s sleek profile, offering an even more aggressive stance due to its reduced interior space and shorter chassis. The car was first unveiled at the 1967 Turin Motor Show, where it garnered significant attention for its distinctive styling and innovative design. Despite the excitement surrounding its debut, the Spider never made it into production. As a result, the number of these vehicles in existence is exceedingly limited, adding to its allure and rarity. Following its appearance at the Turin Motor Show, the prototype was sold to Germany. Over the years, it underwent a thorough restoration, which aimed to preserve its unique character while bringing it back to its original condition. This restoration was a testament to the vehicle’s lasting appeal and the dedication of enthusiasts committed to maintaining automotive history. Today, the Ford Osi 20M TS Spider stands as a rare collector’s item, reflecting a moment in automotive design when innovative concepts were explored with enthusiasm. Its unique status as a prototype, coupled with its elegant yet aggressive design, makes it a noteworthy example of 1960s automotive creativity. The Spider’s story is a reminder of the ambitious and sometimes fleeting nature of automotive design, where prototypes like this one represent both the potential and the limits of their time.
