In 1994 Ferrari offered a convertible version of their 355 known as the Spider. It was developed exclusively by Pininfarina to have a semi-automatic soft top. Ferrari spent a lot of time (1,800 hours) testing the design in the wind tunnel, resulting in what many believe was the first aerodynamically driven blend of elegant style and performance. The semi-automatic soft-top was powered electronically (a first for Ferrari at the time).
