Total Production: 192 1967 - 1975 The Iso Fidia (also known as the Iso Rivolta S4 or Iso Rivolta Fidia) was a four-door sedan produced from 1967 through 1975. Production was exclusive, with a mere 192 examples produced. This was the only four-door model produced by Iso. These vehicles were sporty and had plenty of performance, but also similar amounts of comfort and style. Iso claimed them to be 'the four fastest seats in the world.' Due to the high development costs, these were some of the most expensive cars in the world, even more costly than a Rolls-Royce.
The Fidia was introduced at a European press event in Athens in 1968, followed by production a year later. At the time of the press event, Iso had produced 15 examples.
The design was courtesy of Giorgetto Giugiaro while working at Ghia. The interior featured a polished wood dashboard and hand-stitched leather. The wood dash was replaced with a leather one in 1971. At that time, the instrument panel was re-arranged.
Under the bonnet, and in a similar fashion to other Iso cars, was a Chevrolet V8 powerplant. By 1973, the company switched to a Ford 5.8-liter V8 mated to a ZF five-speed manual or an optional Fords 'Cruise-O-Matic gearbox. By Daniel Vaughan | Sep 2010
