When new guidelines come into pressure in System 1, it is pure to see many alternative interpretations throughout the grid, particularly on these elements that outline the automotive’s total idea. From tail to tip, from the sidepods to the suspension, all the best way to the entrance wing, modifications have swept the 2026 vehicles according to the brand new philosophy this season.
The FIA has sought to restrict the outwash impact that made it troublesome for vehicles to comply with one another by corners in earlier eras, whereas on the identical time introducing a significant new characteristic: energetic aerodynamics on the entrance flaps. This latter aspect mitigates the impact aerodynamic drag would have on energy demand from the engine’s hybrid system.

On this entrance, past just a few onerous factors, the rules grant groups a sure diploma of freedom each in how the wing is interpreted and within the positioning of the actuators that management the rotation of the flaps — comparable to underneath the nostril, or with two components on the mainplane, as within the case of .

The pattern adopted by most groups is to have two separate components rotate – the utmost allowed by the rules – with the intention to maximise drag discount within the areas the place energetic aerodynamics could be deployed.

However one workforce has taken a unique path in contrast with its rivals: .
The place the W17 clearly differs from its rivals right here is the selection of mounting level for the 2 pylons that join the nostril to the entrance wing. On all the opposite vehicles seen to this point, this mounting level is on the primary aircraft, whereas on the W17 the pylons are connected to the secondary aircraft (highlighted in blue in our photos), so solely the flaps on the third aircraft (highlighted in yellow) are free to maneuver.
On this level, the rules do not impose notably strict restrictions: the presence of 1 or two movable components is left to the groups’ discretion, as is the selection of which flaps – outlined as “major” or “secondary” relying on their place on the wing – to make energetic. The primary constraints are as a substitute associated to the axis round which the weather should rotate, the variety of flaps allowed to take action, and the “deflection” relative to the usual place, which is 30 mm for the first flap and 60 mm for the secondary one.

On the core of this lies a unique interpretation of the best way to exploit the wing components. The one aspect able to rotating can be the ultimate one (highlighted in yellow in our photos), whereas the mounted second flap would even have a unique angle of incidence in comparison with its rivals. Throughout Monday’s operating, Mercedes paid specific consideration to this space, even going “old skool” by making use of wool tufts to analyse the behaviour of the airflow.

This strategy inevitably raises some questions. Is that this an answer supposed to stay in place for your complete season, or will there be circuits the place, based mostly on observe traits and downforce necessities, Mercedes chooses to switch the wing? For instance, lately Silverstone has turn out to be a kind of circuits the place groups have begun to lean in the direction of comparatively low-downforce setups.
Insiders in a number of groups have stated that the best stage of downforce when the straightline mode is energetic will differ from observe to trace. It is not essentially the case that they’d wish to shed as a lot as attainable, so a component of tuneability is required.
Up till final yr, we noticed how groups might even make modifications to nostril size through the season with out having to endure a brand new crash check, for the reason that inside construction remained unchanged and solely the outer shell was modified. In principle, this margin would additionally permit for a revision of the place of the assist pylons — however that is one thing that may definitely be answered over the course of the season.

There may be one other fascinating aspect value highlighting on the W17’s entrance wing. By means of the selection of the place sure elements are positioned, Mercedes has created a channel within the decrease a part of the nostril that directs airflow towards the underfloor, all the best way to the T-tray space.

Unsurprisingly, this space options appendages (highlighted in crimson in our photos) devoted to managing and optimising the path and high quality of the airflow downstream.
Within the photos launched through the Silverstone filming day, it seems that a portion of the ultimate flap is definitely mounted, whereas the metallic inserts positioned proper on the finish of that part are tasked with guiding the airflow and producing small vortices which might be helpful for circulate administration in that space.
