Shaped into Ferrari Wind Tunnel
The wind tunnel testing carried out to hone the F430 and F430 Spider's aerodynamics use exactly the same criteria as employed for the F1 single-seaters. Thus Ferrari's engineers have been able to modulate the air flow both around the car, as well as under it, to perfection. The result is a highly efficient configuration that channels air flow for maximum downforce and thus grip. Similarly air is channelled to the engine to increase power as well as optimise the cooling of the transmission, and to the brakes for maximum response even under the heaviest use. Perfecting the cars' aerodynamics has brought about a 50% increase in downforce compared to the 360 Modena.
Lengthy development of the shape and the angle of attack of the new spoiler at the bottom of the front bumper resulted in an impressive increase in downforce over the front axle - up to 130 kg for the F430 and 125 kg for the F430 Spider-which contributes in no uncertain manner to longitudinal vehicle stability and steering precision. Similarly the nolder on the trailing edge of the engine cover works in conjunction with the new diffuser between the rear wheels to increase downforce over the rear axle.
The diffuser features similar fences (deflectors) to those used on Ferrari's single-seaters, and increases the speed of air flow under the tail of the car creating an area of depression and ground effect that pulls the car down. The two intakes for the engine are positioned over the driven wheels in an area of high flow pressure, thus guaranteeing a greater volume of air to the intake manifold. At high speeds, in fact, ram-effect induction accounts for 1% of the engine's maximum power (490 hp).
