After re-establishing Maserati’s viability in the late 1950s, by the early 1960s the highly successful 3500 GT was showing its age. Its successor was unveiled at the Turin Motor Show in 1963, and in 1964 went into production as the Mistral, named after the wind that blows over the Gulf of Lions on France’s Mediterranean coast. Unlike the 3500, the Mistral was a two-seater rather than a 2+2, but it still relied on Maserati’s Grand Prix-inspired dual overhead cam twin-plug inline-6 engine and the reliable ZF 5-speed manual transmission. In addition to the lift-back coupe, a Mistral spider was also produced from 1964 to 1969. Penned by Italian designer Pietro Frau, the Mistral in either form boasts beautiful styling that is widely acknowledged as one of the company’s most attractive designs. When Mistral production ended in 1970, it also marked the end of the Alfieri Maserati’s venerated inline-6, but not before its final development, when its 4-liter displacement and Lucas fuel injection pushed output to 255 horsepower.
