Bubblecar manufacturer Iso joined the ranks of supercar constructors in 1962 with the launch of the Giotto Bizzarrini-designed Rivolta coupé at the Turin Motor Show.
Renzo Rivolta's Isothermos company had begun life pre-war making refrigerators, turning to the manufacture of scooters, under the Iso name, after the war and thence to the highly successful Isetta bubblecar.
Interviewed for Octane magazine (issue 151) Renzo's son Piero recalled that his father liked sports cars but could not find one that really suited him; one that was fast, comfortable and reliable. “He decided that Iso should produce a fast car that was genuinely useable every day, and priced somewhere between a Jaguar and a Ferrari.” The result was the Rivolta.
Iso's first supercar set the pattern for those that followed: Bizzarrini-designed chassis, Bertone coachwork and Chevrolet engines, its future developments including the long-wheelbase, Ghia-styled Fidia four-door saloon, the muscular, short-wheelbase Grifo and the Rivolta-replacement Lele.
Iso's most successful model, the Rivolta was produced up to 1970, by which time a total of 797 cars had been built.
The Iso Fidia (or Iso Rivolta Fidia or, originally, the S4) was a much rarer car, with only 192 known to have rolled off the production line. Each one cost more than a Rolls-Royce at the time.
Contemporary marketing material used the phrase 'Le quattro poltrone piu veloce del mondo' – or 'The four fastest seats in the world'.
The first models were powered by a 5.4-litre 355HP Chevy V8, accelerating the saloon from zero to 60mph in about seven seconds. From 1973, however, a 5.8-litre Ford V8 engine was used, developing some 325HP.
John Lennon bought the second Fidia ever made.
Pete Townshend, Sonny Bono and James Last, among others, also fell for the undoubted charms of the Fidia.
