In 1961 “Spyder” became the official name for the Maserati convertible versions, intended for the overseas market. The Turin Master coach builder Alfredo Vignale won the contract for full production of Maserati’s open-top version of the GT. The design by Giovanni Michelotti differed from that of the Touring Coupe by its angular and muscular appearance. The Touring also had a drop-top version inherited from the coupe, but only three were ever produced. Of the Vignale version 243 were sold.
Mechanically, the car was identical to the coupe except that the wheel-base was shortened by 10 centimeters and was made of steel. The doors, engine bonnet and trunk-lid were made of lighter metal as was the optional hard-top. Electric windows were standard fit. The GTi version had a top speed of 220km/hr.
