Create listingHistory of the Osella FA
The Osella FA is rooted in the competitive spirit of 1980s motorsport engineering. Developed by Enzo Osella in 1983 specifically for the IMSA GTP class, the FA stands apart as Osella's only closed-body racing car. Its creation was focused on competing in American endurance events, notably making its public debut at the 1984 24 Hours of Daytona. Drawing from Osella’s expertise in open-cockpit formula cars, the FA project (internally designated "FA 2000 IMSA") borrowed high-performance elements, including a race-proven BMW powerplant and cutting-edge chassis design, securing its status as a bespoke racing prototype.
Model History
Within Osella’s lineage, the FA marks a distinctive project as the only closed-body model ever constructed by the marque. Its development targeted the GTP regulations, leveraging experience from Osella’s successful Formula 2 cars, particularly those powered by the BMW M12/7 engine. No direct predecessor or successor exists for the FA, making it a singular experiment within Osella’s predominantly open-wheel racing career.
Highlights of the Osella FA

- Powered by a 2-litre BMW M12/7 engine, the same type which delivered Formula 2 Constructors’ Championships for Osella in 1982 and 1983.
- Features a lightweight Avional 20/24 tube frame chassis, Hewland 5-speed gearbox, and all-magnesium 13” wheels.
- FIA and CSAI certified, including original Osella construction documents.
- Extremely limited: only one FA ever built, chassis No. 001.

Technical Data
Special Editions and Collectible Models
The Osella FA is itself a one-off model—no variants or limited editions were produced. Its status as the only closed-cockpit Osella in history and its bespoke engineering for IMSA competition make it a unique collectible.
Weak Spots and Common Issues
Technical data does not indicate widespread weaknesses, but as a unique prototype, parts supply is extremely limited and bespoke, making servicing a challenge. Specialist knowledge is essential, especially for the BMW engine, Hewland transmission, and Avional tubular chassis components. Maintenance requires certified expertise in FIA-standard safety systems and historic motorsport vehicles.
Engine and Performance, Transmission and Handling
The 2-litre BMW M12/7 inline-four engine, renowned for its success in Formula 2, provides the Osella FA with 350 horsepower in endurance trim, paired with a Hewland 5-speed gearbox. The rear-wheel-drive setup, Avional tubular frame and lightweight magnesium wheels deliver exceptional balance and rigidity, critical for endurance racing. With Brembo braking systems and a focused, race-developed suspension, the FA was built for high-speed stability and reliability over extended stints. Given its one-off status, FA chassis No. 001 is the definitive and sole example. It utilises components proven in high-level motorsport, such as the BMW M12/7 engine and Hewland transmission, highlighting both performance heritage and technical sophistication.
Interior, Comfort, Exterior and Design
The Osella FA’s design is defined by its fibreglass closed cockpit body, developed for aerodynamic efficiency in endurance racing. The 25 CO4 Avional frame is a testament to precision engineering, balancing strength and low weight. Authentic period-correct details include magnesium wheels, FIA-certified fire suppression, and streamlined bodywork for the GTP category. As a functional race car, the cockpit is strictly utilitarian, designed for driver safety and quick servicing during pit stops.
Other Information
The vehicle is available for online inspection via video platforms. Certification from Osella, FIA Chip No. 1922, and CSAI technical pass accompany the car. Its participation in numerous historic events in Italy adds provenance that is unattainable for any other Osella example.
Summary
The Osella FA represents a rare convergence of engineering ambition and motorsport heritage, built as a singular prototype for the GTP class. With unique technical specifications, original documentation, and unmatched rarity, it is an essential chapter in Osella’s racing narrative—making it a compelling piece for connoisseurs of prototype endurance cars.
