How The New Ferrari FXX-Ok Evo Can Make Over 1,800 Kilos Of Downforce

Ferrari simply introduced the Evo model of its LaFerrari-based FXX-Ok, and my god have the aerodynamicists gone loopy with it.

Ferrari confirmed the brand new hypercar on the Finali Mondiali race on the Mugello circuit in Tuscany. The automotive, which the Italian automaker says melds numerous design components from Method 1, GT3, GTE and different racing sequence, will not be solely lighter than the FXX-Ok (because of an F1-derived carbon fiber forming course of), nevertheless it’s additionally obtained fairly a bit extra downforce.

Ferrari says it spent a yr working computational fluid dynamics simulations and wind tunnel exams to get the FXX-Ok Evo’s downforce numbers on par with GT3 and GTE automobiles. The result’s a 23 % higher downforce coefficient than the FXX-Ok, making the brand new automotive’s coefficient 75 % higher than the highway automotive, the LaFerrari.

In sensible phrases, that signifies that at 124 mph, the FXX Ok Evo will make 1,411 kilos of downforce, and on the automotive’s high velocity, that quantity goes as much as an insane 1,830 kilos. For reference, that’s in regards to the weight of a Clydesdale horse.

Ferrari says the “twin-profile” mounted wing on the tail was an enormous a part of that added downforce, and that it really works “in seamless synergy” with the automotive’s lively rear spoiler, whose controls logic Ferrari reprogrammed for this utility.

Becoming a member of that large rear wing are two aspect fins and a central fin, the latter of which helps stabilize the automotive at low yaw angles and likewise “helps the motion of the three delta (triangular) vortex turbines.”

These vortex turbines, Ferrari says, badist clear up the wake exiting the ducted cooling module from the hood earlier than that air strikes the wing. It additionally creates a “downwash part within the circulation,” which apparently helps the twin-profile setup to supply downforce. This all ends in 10 % extra drive pushing down on the again of the automotive.

Engineers additionally enlarged the vent within the rear wheel arches to badist channel out the wake created by the wheels. This, Ferrari says, smooths out circulation to the rear diffuser, boosting its downforce by 5 %.

Aerodynamicists and designers additionally modified the form of the perimeters of the entrance bumper, hollowing out the surfaces underneath the headlights to make room for “flicks” (that are break up by turning vanes), and together with one other air consumption in entrance of the wheels.

Beneath, Ferrari added vortex turbines on the stomach pan, which “capitalised on the accelerations created by the rear system and the entrance underbody” and in the end added 30 % of the automotive’s extra downforce over the FXX-Ok.

The automotive additionally will get redesigned brake air intakes, a re-tuned suspension, a much bigger inside show, and a brand new steering wheel.

The Ferrari FXX-Ok Evo, which isn’t meant for highway use and “won’t be utilized in competitors exterior its devoted programme,” can both be purchased outright as a part of an “extraordinarily limited-run,” or present FXX-Ok homeowners can have their automobiles upgraded.

If I owned an FXX-Ok, I’d be tempted by this bundle; that simply looks as if an terrible lot of downforce-y goodness to cross up.
