How Ferrari used computer-aided surfacing to redefine its aerodynamic DNA
In short: The Ferrari 360 marked a radical departure from the sharp angles of the 1990s. By blending a new all-aluminum space-frame with the first-ever use of computer-aided surfacing, Ferrari created a curvaceous, aerodynamically efficient body that traded pop-up headlights for a sleek, modern silhouette.
Between 1995 and 1997, Ferrari tasked Pininfarina with creating a 'clean-sheet' design to usher in the new millennium. This project required a complete stylistic break from the previous decade's aesthetic, specifically moving away from sharp angles and retractable headlights. The result was a curvaceous body featuring a long wheelbase, wide tracks, and a cab-forward stance that emphasized the mid-mounted V8 engine. Representing a technical breakthrough, this model became the initial Ferrari crafted via computer-aided surfacing, employing Alias software to polish shapes prior to clay milling.
The engineering behind the 360 was as revolutionary as its skin. By collaborating with Alcoa, Ferrari manufactured an all-aluminium space-frame chassis weighing 28 percent less while offering 40 percent more stiffness than earlier steel versions. To achieve this without sacrificing performance, the car's dimensions were increased by 10 percent. The bodywork was designed to integrate seamlessly with this frame, utilizing twin rear diffusers to generate ground effect and eliminate the need for a traditional rear spoiler. It also introduced transparent headlamp covers, a production first for a Ferrari V8 berlinetta, which removed the weight and drag penalties of pop-up units.
The 360 served as a versatile platform for various high-performance goals. The Modena was the standard production model, while the Spider was a dedicated convertible designed with reinforced sills and a stiffened rear bulkhead to maintain torsional rigidity. For track enthusiasts, the Challenge Stradale pushed the limits further, utilizing Resin Transfer Moulding for bumpers and Brembo carbon ceramic brakes borrowed from the Enzo. These modifications allowed the Stradale to be up to 110 kg lighter than the Modena, achieving a 3.5-second improvement per lap at the Fiorano Circuit.
