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

@pinsaroulette16 True… as I had predicted:

@dr_obbs What would he accomplish away? Not catching Max and then hold up LEC when his softs degrade at lap 50.

@the_zb_ @dr_obbs From the same thread…

@wearetherace @XPBImages Another example of why drivers should let strategists strategize.

@dr_obbs Ok, I was wrong… not lap 50, lap 46. 😉

@dr_obbs Or just driving a better car—faster, easier on tires—can guy in 2nd? 🤷🏻‍♂️

@brakeboosted @f1_naija Agreed. Makers of the rule book could not have foreseen such a scenario, so complex (and, dare I say, stupid) are the rules.

@3c3p3d The “Swap Shop” 275! 😉

[DesignIng Cars ⚙️ @EngDesignIng]

@brakeboosted Yes and luckily McL were worse on the day: started on slicks (1 step harder though), ran the hards, pitted late under SC, and almost took each other out.

[DesignIng Cars ⚙️ @EngDesignIng]

@brakeboosted Exactly this.

I seem to remember how, back in the Brawn/Baldessari days, they tested for, and used, actual test data to predict performance during changeable conditions to make informed decisions… then Domenicali happened. 🤣

[DesignIng Cars ⚙️ @EngDesignIng]

@brakeboosted I agree. Something wrong in that team. Think they can pull a miracle with a daring strategy… it never works.

Somebody needs to drive into their had the Brundle advice: ALWAYS BE ON THE RIGHT TIRE FOR THE CURRENT WEATHER.

You easily lose a pit stop in time lost if you’re not.

@MateuszMrz8 @ScarbsTech 👍

How it works…

[DesignIng Cars ⚙️ @EngDesignIng]

#SF26 flipper” RW flaps looks—as suggested by some—to be using rack & pinion arrangement in both L & R end-plates. Two actuators need to be synced. Single sided would risk binding if distorted.

Note what look like flap separators/vanes also act as snubbers.

Great pic by the real @xaviAeroporn confirms Audi using “decomposed” (multi-link) upper wishbone—in contrast to all others using multi-link lower. Merc, I believe, are only team with “classic” wishbones upper and lower.

@adrianfclarke @rustivalfest @waynejburgess Pretty adventurous designs by Nissan/Datsun in the 70s—even if constrained by imposed proportions and wheel size—but let down by the overly fussy lights and ornamentation.

[DesignIng Cars ⚙️ @EngDesignIng]

@ScarbsTech 1.6 litre, yes?

@lupin_Dagger @gasolinaowl No, just the 90 deg. V-angle on the later cars.
