Record-breaking efficiency for exceptional performance
Aerodynamic solutions derived from Maranello’s experience on the track augment downforce without increasing drag, resulting in an efficiency figure of 1.67, a record for a road-homologated Ferrari. Downforce is 50 per cent higher than on the previous model despite drag being reduced.
The front of the car is dominated by the central Aero Pillar and an F1-inspired double spoiler which boost the efficiency of both the radiator and downforce generation.
The 488 GTB has an innovative aerodynamic underbody that incorporates vortex generators, special curved aerodynamic appendages which accelerate the air thereby reducing pressure. The result is that the car’s underbody is “sucked” down to the ground and downforce is higher but drag is not. This contributes to overall downforce generation of 325 kg at 250 km/h.
The large rear diffuser has curved fences which optimise the expansion of the huge amount of air channelled under the car. It also features variable flap geometry controlled by a CPU, integrated with other vehicle control systems, which adjusts the balance between increased downforce (flaps closed) and drag reduction (flaps open).
The Ferrari-patented blown spoiler is a new solution. Air enters an intake at the base of the rear screen and exits via the bumper. This guarantees increased downforce and avoids having to extend the height of the rear spoiler and thus helps keep drag low.
he base bleed air intakes on the car’s sides are divided by a central flap. The flow over the upper part of the flap, which is also used for the engine air intake, is deflected and exits from the tail area to reduce the drag caused by the low-pressure wake directly behind the car. The flow from the lower part of the flap goes to the intercoolers to cool the intake charge."

Αυτο το 1.67 πως υπολογιζεται, και υπαρχουν δημοσιευμενες αντιστοιχες μετρησεις απο ανταγωνιστικες
κατασκευες?
