Using a shortened version of the Rivolta chassis, the Iso Grifo (presented in 1965) was a GT with an elegant yet aggressive character, designed by Bertone. Various engines were used, with powers ranging from 300 to 365 up to 400 Hp for the 7-liter (of which around seventy were built). In the early seventies the front part underwent a restyling. A lighter version was produced by Bizzarrini and called "Strada". From 1965 to 1974 the Grifo produced were about 500.
