The extremely elegant lines of the Mistral have been further enhanced in the cabriolet version. As with the coupé, its design was the work of Giovanni Michelotti, and Vignale was the coachbuilder. It was offered with a choice of either the 3.5-litre engine from the 3500 GT or the 3.7-litre from the same car, to which a 4-litre version was added a few years later. As with the coupé, during its first year of production the car was still known simply as the ‘2 Posti’ spyder, before the more poetic name of Mistral was adopted. Even with the 3.5-litre engine, performance was much more than poetic, with 235bhp available under the bonnet. The bodywork of the Mistral convertibles was predominantly steel, with the bonnet, doors and boot lid in alloy. A very rare optional hardtop was designed for the car and also made from light alloy.
