The project began when OSI (Officina Stampaggio Industriale SpA), an Italian car manufacturer founded in 1960, decided in 1967 to build something a little bit different for that year’s Turin Motor Show. The Silver Fox featured a 1.0 litre Renault Alpine four-cylinder engine which was mounted in the left-hand side of the vehicle, just behind the passenger seat. Despite the poky little engine, the Silver Fox was capable of reaching 155mph.
Aside from the unusual body configuration, the OSI Silver Fox was equipped with some unique aerodynamic aids. Between the two fuselages are three individual spoilers. The front one was manually adjustable when the vehicle was stationary, the middle one could be adjusted while on the move, while the rear spoiler was in a fixed position.
