Ferrari F40 Design

Presaging the F50 and the FX, the Ferrari F40 was formed entirely by its function. A pleasing shape, it reflected the GTO from which it descended, essentially aerodynamically 'finishing' that model's 5-unit Evoluzione study. Airflow, indeed, was the prime stylistic motivator in this Pininfarina design. Before placing such power in the hands of clients, it was necessary to ensure predictability and stability at the edge. Its most dominant features are aerodynamic aids: the low smooth nose with precisely formed intakes, the recessed doors and the numerous NACA-type ducts around the car, the vented plexiglass engine cover directing airflow to the large rear wing, and the lower rear diffusers. Like all Ferraris designed for racing, the F40 sported enamel Scuderia Ferrari badges on its front fenders.

Aerodynamics:

The F40 was designed with aerodynamics in mind, and is very much a creation of its time. For speed the car relied more on its power than its shape. Frontal area was reduced, and airflow greatly smoothed, but stability rather than terminal velocity was a primary concern. So too was cooling as the forced induction engine generated a great deal of heat. In consequence, the car was somewhat like an open-wheel racing car with a body. It had a partial undertray to smooth airflow beneath the radiator, front section, and the cabin, and a second one with diffusers behind the motor, but the engine bay was not sealed. Nonetheless, the F40 had an impressively low Cd of 0.34 with lift controlled by its spoilers and wing.
