Just like Toyota, Williams seem to need some extra winglets in order to have the required amount of downforce needed on a circuit like the Hungaroring. Instead of one element, three were present in Hungary. An important difference with the Toyota setup however is the fact that all of these small wings are pointing upwards and therefore work opposite to the Japanese items.

The team that gives you wings has now grown some wings and removed a few ears on the car. As of the Canadian GP the team used Renault-like nose ears just above the track rod to allow better airflow above that rod and reduce any effect that would have on the surroundings. These have now become obsolete and are replaced by small wings positions more in front. Just like the ears, they do not create downforce as a single element as they point downwards.
Only as recent as at the GP of Germany, new winglet were noted at Toyota, and this time around they have added one more. A little lower than the ones already there is a new wing that has a similar shape to the other white element. Also visible on the image are the gurney flaps at the bottom of these two trailing winglets, resulting in an upward force of the wings, contrary to what one may expect. The aim there is to get more air onto the rear wing and do so in a clean flow.
Toyota continue their impressive development pace with yet another update. This time the winglet in front of the sidepod inlet has been changed in order to gain downforce in the middle of the car. The size of the vertical plate has been reduced while the wing at the inside of it is now pretty similar to that of the one seen at BMW.
While Renault have been running double flipups since the beginning of the season, Ferrari have now adopted a similar thing too, be it a little smaller of what we see at the French team. The extra element was introduced at Hockenheim and used again at the Hungaroring. It is attached on the upper element at two points and adds to the reduction of air resistance on front of the rear wheel.
After Renault introduced their version of the sidepod shield at Montreal, BMW now also have one. Instead of a shield though, it is more of a winglet, as at the inside of the vertical place, a small wing is attached to push air upwards and gain some downforce. The plates of Renault and Honda do not have any such wing and function only as guidance for the air passing by.
This double wing configuration is not new for Toyota but it displays the level of aerodynamic development put into current Formula One cars. an airbox wing at the beginning of 2005 looked mostly like a single stabiliser that created no downforce on its own. The displayed elements are those raced at Hockenheim and is a combined wing with curvatious leading edges on both elements. While the second element has a straight trailing edge and is a stabiliser, the first (red) winglet is not... Read more
After Ferrari and Toyota, the modest Toro Rosso team is the third to have developed a wheel rim ring. The carbon element is glued inside the wheel rim, officially meant to improve brake cooling. Just like at Toyota, the device is not just a ring as it extends into the wheel in order to guide hot brake air out of the rim. It must be noted though that Toro Rosso is the first team to introduce this with Michelin tyres, meaning that we might see more teams introduce it in coming races, ... Read more
Renault showed up at Hockenheim with again an updated aerodynamic package. This time around the ears were again replaced by single element wings instead of the double element layout seen at Canada and Indianapolis. These simple items were also present at Magny-Cours. Secondly, a vertical fin was added on the upper front wishbone. It is exactly as far away from the nose as the width of the camera hose positioned just in front of the wishbone. The element is most likely to straighten ... Read more
While Honda have just recently adopted the previous Renault style of front wing upper elements, the Renault R26 will have a new front wing. The new upper element attachment points are based on Ferrari, as the element now spans from the endplate to the nose cone. The nose attachment is very curvy here and could allow the wing to still flew down a bit at both sides, contrary to Ferrari after they changed their wing because the FIA asked to. The new wing is due to debut at the upcoming... Read more
