AERODYNAMICS
The objective with the Daytona SP3 was to introduce aerodynamic solutions that would make this the Ferrari with the highest level of passive aero efficiency ever . This required painstaking attention to detail when designing the radiating masses for efficient heat dissipation . Management of hot air flows was thus vital to defining a layout that was as integrated as possible with the overall aerodynamic concept .
The increase in the F140HC ’ s engine power output meant a corresponding increase in the thermal power that had to be dissipated and thus an increase in the radiating masses for the coolant . To allow for the aerodynamics solutions required for the front end meant concentrating development on cooling efficiency first and foremost . Thus detailed work went into the design of the fan housing , the opening on the underbody to evacuate hot air and the intake duct which were all optimised to avoid having to increase the size of the front radiators .
The front of the Daytona SP3 is a strikingly harmonious melding of form and function . Either side of the central radiator grille are intakes to the brakes ducts and to the channels that vent through the outlets either side of the bonnet to create a blown duct that contributes to front downforce generation . Below the headlights are two aero flicks which increase downforce . The vertically stacked winglets inside the corners of the bumper guide the airflow into the wheelarch , creating an inwash that reduces drag by realigning the flow along the flanks and contains the turbulence generated by the wheel wake .
Considerable research went into the design of the flanks which benefitted from the layout of the radiating masses for gearbox and engine oil being shifted towards the centre of the car . This solution paved the way for the integration of side channels into the doors , allowing the intake ducts for the radiators to be moved forwards in the chassis . As a result , the front wing creates an ideal section for the intake ducts and captures fresh air that is also highly efficient in terms of cooling the radiators .
The high level of integration of aerodynamic functions into the design is demonstrated by the engine cover , which features a central backbone structure to channel fresh air into the engine intake as well as provide outlets to vent hot air from the engine bay . The engine air intake is at the base of the backbone design to shorten the distance to the air filter and minimise losses . The longitudinal slots that separate the backbone section from the single-piece rear bodywork dissipate engine heat and capture fresh air thanks to their interaction with the vents located between the blades on the rear bumper .
