The Fiat X I/9 coupé with a mid-mounted engine made its Swiss debut at the 1973 Show. At this time, the Geneva team Scuderia Filipinetti was under contract to Fiat to run the 128 in the European Touring Championships. In the context of this collaboration, an X I/9 coupé was prepared for the Targa Florio by the engineers Parkes and Dallara but it never took part in the race due to the untimely death of Georges Filipinetti.
