The Iso Fidia, also known as the Rivolta Fidia, was a series of sedans introduced in 1967. Originally launched as the 'Iso Rivolta S4,' the Fidia was Iso's only four door model, featuring a sleek design penned by Giorgetto Guigiaro. These rear wheel drive cars were initially powered by a Chevrolet-sourced 5.4L V8 engine, but disagreements with General Motors lead to the use of a Ford 5.8L V8 engine starting in 1973. Both automatic and manual transmission options were available on the Iso Fidia, which was produced until 1974 with a total of 192 examples built.
