The 458 Italia is the result of a combination of functionality and style aimed at guaranteeing optimal performance and driving experience. The development of the car started from the usage of CFD (Computer Fluid Dynamic) techniques to optimize the internal and external flows interaction and management. Experimental testing as well as work on the rolling belt in the wind tunnel played also a crucial part in the early development of the vehicle. Numerous tests and configurations were conducted before leading to the actual structure.

The engine is cooled by using large trapezoidal radiators which maximize efficiency in terms of space. The radiators inclination also reduces the impact of the Cd, whilst down force (CI) generation is guaranteed by the different amount of airflow through the vents on the wings. The radiators position cooling the dual clutch F1 gearbox was chosen for aerodynamic and packaging reasons. The hot air from the radiators generates the Base Bleed Effect, that was patented by Ferrari during the FXX development and that allows venting into the vehicle’s low pressure trail below the molder. The process works on the principle of transferring energy from a high to a lower pressure area and cuts drag. Air flows from the vents on the front wings have been designed to avoid a negative aerodynamic effect on the air flow to the engine air intake. The air intakes for engine bay cooling have been positioned on the aerodynamic underbody to respond to three main aerodynamics requirements. First, this position allows to keep the side of the car smooth, with benefits to the overall 458 Italia efficiency as well as improving the rear diffuser functioning. Second, it allows to exploit NACA, a system developed with the F430 GT2 and consisting of ducts specifically positioned on the underbody to enhance the rear diffuser functioning. Lastly, having the air intakes for engine bay cooling on the aerodynamic underbody optimizes the usage of the natural high field in front of the rear wheels for maximum air flow, with a consequential drag reduction.

Separate air flows must be managed in order to generate the front down force needed. The front dam causes a localized and controlled separation of the flow which consequently increases down force over the front axle without compromising the functionality of the remaining underbody. The aero-elastic winglets on the front bumper are outlined to ensure uniform air channeling to the radiators, whilst simultaneously generating down force.
