Fidia S4

In 1967, ISO Rivolta tackled the emerging market for high-performance sedans by launching the S4 (code name: "Four Hatches"), later known as the Fidia.

Piero Rivolta asked Giorgetto Giugiaro to interpret his idea of a sedan in a way that perfectly represented the DNA of the Bresso-based company.

The young designer had just arrived at Ghia, at that time owned by Alejandro De Tomaso, a longtime friend of Piero's, as chief designer. Giugiaro adapted his Grifo concept, which he himself had designed while still at Bertone, into a four-door sedan, characterized by the idea of speed, elegance and power. A perfect synthesis.

The car remained the same as its predecessor, the IR300/340, with a 5358cm³ four-barrel carbureted Chevrolet V8 engine (offered in both 300hp and 350hp configurations).

The company then struggled to find a suitable name for the newborn: eventually “Fidia” is chosen, to honor the famous Greek architect and sculptor who designed the Parthenon in Athens, chosen as the setting for the car's presentation to the international press.

The car was a triumph of elegance and quietness: no drafts, clean lines and leather interior. An exclusive environment to drive in safety. Not to be outdone, it was another example of combining European design with an American heart.

Production of the Fidia began in 1968 and ended in December '74, with the closure of Iso. A total of 192 examples were built. The Fidia was the personal car of musician John Lennon, who owned three examples.
