By the GP of Hungary Ferrari introduced at least 7 different front wing specs . The major wing revisions came alongside with extensive changes on the car reflecting the team’s will to erase the race pace handicap shown from early winter testing between the F2012 and the top cars (McLaren , Red Bull , Mercedes or even Lotus) . However some minor changes took place independently .
The most striking feature of all concepts is the multiple flap design close to the endplates . At past Mc Laren raced with four or even five flapped wings but those concepts were abandoned due to revised 2009 technical rules . However slots on flaps are still allowed , a freedom which Ferrari took advantage to the maximum and opened a new era that I call “a Ventalia” type design.
Spec : A Debut : Launch Raced : Australia , Malaysia
The most striking feature on the launch spec is the multiple slotted flap pattern that transforms the two flap concept into an effective four profiled .The gains in not only higher amount of downforce but also making the wing less sensitive to stall .
Spec: B Debut:pre season test at Barcelona on March Raced:Not yet
It was obvious that lack of sufficient front downforce was among the major bugs of the new car that had to be solved .Thus a major wing update came at the third pre season test . The new wing had completely redesigned flaps including a different way the flaps attach to the endplate , triple slotted main flap and a large gurney tab pointed in green arrow. Modifications occurred also on cascades winglets and endplates which featured ducts to redirect air inside the wing area(all changes marked in yellow) . A more detailed look on the endplates reveals the strategy of Ferrari to redirect the lower flow inside the front tyres through the ducts while the upper flow is pushed away to the outer tyre surface .It is good to remember that Mc Laren curved the path of ducted endplates a few seasons ago .
The B spec was also tested at Malaysia and China . However the B version proved not suitable for the car needs thus never qualified to race .
Spec :C Debut : China Raced : Not yet
A modified B spec was brought at China lacking the large triangular gurney tab to benefit a greater top speed .
Spec : D Debut : China , Raced : China , Bahrain
Ferrari raced in China with another new spec which included apart from the gurney tab lack , revised endplates and cascades ( in yellow) . The new upper deck has a deep cut close to the endplates to favor further drag cut .
Spec : D Tested : Spain
It was also tested at Catalunya having a Santander logo addition on the endplates
Spec :E Debut: Mugello test on May Raced: Spain, Monaco, Canada, Valencia, G.Britain, Germany, Hungary
Mugello test was very fruitful for Ferrari as many new parts undergone evaluation testing , including new rear end , exhausts and a new front wing. Speaking for the front wing changes occurred on the wing sides and particularly the endplates. They may look similar at their lower part but the top is completely new , less curvy having a small horizontal triangular fin at the rear to improve airflow management close to the tyres . The top rear fin concept is not new but derives from older seasons .Moreover the cascade inner winglet adopted a new double profile and a revised trailing edge .Finally some modifications took place on the outer flap separator ( all changes are marked in yellow ) . Ferrari brought at Spain both E and D spec in order to perform a comparison test between the new and the old version. Finally the nose pillars are half painted since in black carbon color .
Spec : F Debut : Europe ( Valencia) Raced : Not yet
This spec was tested at street circuit of Valencia , Silverstone and Hungaroring . It featured a new second flap which resembles more to launch spec , new flap separators and a deep cut on the triangular winglet of the endplate .The endplate itself inherited multiple ducts to enhance further the Ventalia concept efficiency .
Spec : G Debut : Germany Raced : Not yet
The latest update tested at Hochenheim and Hungaroring . It had modified endplates having even more ducts, five now instead of four , the cut on the winglet is gone and the flap separators gained a simpler appearance for both aero and mechanical reasons . Finally an extra slot was added on the second flap close to the endplates , increasing so the effective profile of flaps from five to six !
