F1 2025 Tech Review: McLaren MCL39 Front Suspension MCL39

FWD lateral link and AFT leading arm in lieu of classic lower WB, setback steering rack with the track rod stacked between links to the upright ahead of the wheel centerline, it was a departure from its predecessor… 1/10

@criseferrari_ Agree…

@brakeboosted 👍

In any case, the good news is that car showed good pace at a track that is (was?) always considered a bellwether for good performance at all other tracks.

And if pre-planned ADUO mods are deployed quickly… nothing is off the table for the championships.

#F1 #FormulaTecnica

Un lavoro raffinato della #Ferrari sull’aerodinamica della SF-26 che va oltre le forme: concetti estremizzati e utili ad una precisa causa per ottimizzare le potenzialità della vettura italiana

@brakeboosted They either have a lot of confidence in a lower deg or just trying to get into the lead and think they can control from there. 🤷🏻‍♂️

Maybe would have been best for LEC to start on (H) with and go long.

@brakeboosted @wearetherace Good catch with flipped upper element. 👍

This change was quite obviously made to be sympathetic with the more down washing flow at the entry to the new undercut channel as you highlighted in green.

[DesignIng Cars ⚙️ @EngDesignIng]

@RosarioGiuliana @wearetherace 👍 Interestingly, the new “bulge” looks to have been spliced into the unaltered upper bodywork. There’s an apparent seam where they join.

@LUDENClassics Countach 👌

@hrc_NT @carpentiers_f1 ^^ this

@brakeboosted Wait, Merc getting ADUO? Hopefully what Ferrari have in the works already (if true) will move the needle on the dyno.

[DesignIng Cars ⚙️ @EngDesignIng]

@wearetherace Was wide on corner entry and picked up a much of marbles

@brakeboosted Put an end to this misery please.

[DesignIng Cars ⚙️ @EngDesignIng]

@brakeboosted Should have done like HAD, keep track position.

[DesignIng Cars ⚙️ @EngDesignIng]

@carpentiers_f1 @brakeboosted 👍 Great pics as usual.

About 1️⃣ this is the upper WB rear leg pick-up point—which has been modified a few times this year, as shown—but this change does not affect steering geometry per se.

Steering changes would relate to the steering rack & deformable multi-link lwr “WB”.

CORRECTED: SF-26 front suspension layout.

Upon further review… slight correction to the original post: https://t.co/pk9vOKlmj8

[DesignIng Cars ⚙️ @EngDesignIng]

@adrianfclarke Yes, I was thinking R8 when writing the post. In the R8’s case the blade was more identifiable as a scoop with rounded aft corners and not so upright.

Also that car still looks unbalanced almost looking like long-nose front-engined car with greenhouse volume decidedly aft.

@ScarbsTech @xavigazquez Could be but if they created the dip for area rule reasons, and so to reduce losses (likely to maintain flow energy to RW), adding more “furniture” in this area seems unlikely. 🤷🏻‍♂️

[DesignIng Cars ⚙️ @EngDesignIng]

@xavigazquez @McLarenF1 👍

Note no end-plates and rounded edges to reduce sensitivity to sideslip flow. 🤔
