I find this shot intriguing!!
I seem to be seeing three lower wishbone arms…
Is the front lower arm is the steering arm and the rear two arms a very narrow wishbone? (Kinematically & structurally this would seem very non-optimal).
Is the front (upper) of the two rear (lower) arms the steering arm? (Ergonomically this seems very non-optimal - putting the drivers’ family jewels in very close proximity to a directly linked wheel/rack!)

Three pivots just doesn’t work!

Great idea for aero conditioning though!

They moved the rack from in front of the lower wishbone to behind the lower wishbone

This is now Ackerman steering with steering rod 'behind the axle line'.
Jokes apart, in what way does it influence the assembly / repairs / adjustments to be done in the paddock ? easier/harder/nodifference ?

Thank you! I had forgotten that, steering column does look ‘close’ to driver anatomy!

Yeah, I also thought that there must be a mechanic steering column to the cylinder and it would be probably between the drivers leg, which would be odd.

McLaren makes those on their own. Glad to see them have this level of independence, unlike the other Mercedes customers. This car didn't look that different on the flesh when compared to the final spec MCL-60. But clearly, a lot of work went under the hood to make the platform that much better.

I've been looking at this photo for a couple of days now and I can't shake the feeling that the area where the air flows accelerate the most, the area where the center with the minimum pressure is located, has moved back closer to the rear, closer to the diffuser area. Perhaps thanks to this, it was possible to stabilize balance and controllability. Or this is a primer for further improvements.

But everything looks exactly like this: the pressure gradient under the floor and the center of gravity of the chassis have become much closer to each other in relation to the longitudinal axis.

Interesting little detail at the rear of the diffuser, a change in roof height towards the outer edge to encourage outwash (working with the lower vanes on the rear hub).

Yes it is definately tighter all round, increasing the airflow to the wing and diffuser, on top and underneath the sidepod.

Is it wider by a little?

Turns out the bodywork is a little wider. This is why the undercuts are waterslides are deeper/wider. It'll also be helping with that dirty air, particularly at the low speeds.

I drew this up before I saw your comment but yes, that was the most interesting part or me after the incredibly small gearbox underside.

It's at the exit where I have put the scrawled red arrow, I think

Yep, that’s the bit that I was seeing.
