Ferrari: Spanish Rear Wing Extension


This 30mm extension was fitted the Ferrari 150 in Spain


How could this be achieved legally?

the supports) ;
greater than 45° with respect to a lateral axis) ;
– be between 2mm and 5mm thick ;
– be rigidly fixed to their respective sections ;
– be constructed from a material with modulus greater than 50GPa.

Ferrari have sandwiched and split the separators to form the extension


Each Separator also forms the 30mm extension

  1. Ridiculous. If they plan to ban it, they should ban it outright since even qualifying hasn’t started yet. Also, it’s not exploiting a loophole since they are interpreting the rules differently (thus illegal unconditionally).

    Ferrari International Assistance..

    • It is exactly the same loophole as the blown diffuser, since moving aerodynamic parts are not allowed. Still they are here since more than a year. Why do you not attack FIA for that? But if ferrari does something similar then as you see FIA responded on the very next day.
      So your FIA criticism is not very biased.

      • It’s absolutely not the same loophole – the rule in question has nothing to do with moving aero parts at all.

      • The moving aerodynamic parts rule is ridiculous anyways. The front wheels have a huge effect on the aerodynamics of the car, and the drivers all control their movement with the steering wheel throughout the race.

        Essentially it’s an F-duct ban… that’s it.

  2. What I don’t get is why it’s not banned by the current rules – surely the corner to get from the support to the flap is a “curve” (a very tight one), and isn’t on the horizontal plane, or am I misreading this?

    • I meant that is is a loophole, as any loopholes. But it gets different treatments from the FIA, which as I see is not the same in the two cases.

  3. RB are allowed to have flex wings.
    But other teams get their developments banned on the grounds of it not been within the “spirit of the laws”. Ferrari brings a cleverly designed wing to the GP it gets band not because it is illegal but because it is not within the “spirit of the rules”. Same thing happened to Ferrari’s movable floor in 2007. Which by the way at the time was not illegal but not within “spirit of the rules”.
    RB has wings that flex which constitutes movable aero and some how its fine?!?!

  4. one question can ferrari cut the rear wing pillar (post ) for 30mm ? in that case maximum height will be 920mm from flor of car plus these new gurney flap 30mm =950mm…is that legal?
    sorry for bad english

    • Sadly no, the rear wing sits within a fixed set of dimensions. It cannot be lower than 730mm. which is why ferrari found this loophole to make the wing 30mm taller than is designed to be.

      • ok thanks for replay, so they can’t do anything about that..reduce height of plate where is sing santander so that gurney flap will be in level with maximum height of whole wing?

  5. I can’t believe this is being credited as a loophole or even a grey area. The regulation says gurneys may be fitted BETWEEN the supports – not that they may form part of the support. Thus the gurneys are not part of the exclusion.
