Alpine A523

A place to discuss the characteristics of the cars in Formula One, both current as well as historical. Laptimes, driver worshipping and team chatter do not belong here.

Are the "cuts" on the new front wing flaps for flexibility?

I have to think. The flap rolls back at speed providing a bit of drag reduction. This was something Alpine missed last season. Ferrari/Mercedes/RedBull took great advantage of this.

Then Alpine, Mercedes & Red Bull FTW.
In that order.


The increase of the 'cannon tube' size/fatness may be the sign that the 'water slide'/trench got deeper and is almost separating the sidepod in two parts.
So maybe hot air will follow path '2' more in 2023 and exit more directly through cannon.

Or not.

The AM has an extreme water slide, and a fat transition for the air to transit from sidepod to cannon exit.
The A523 seems to be skinnier there. But how is its water slide?
We'll see, in Abu Dhabi 2023

That new hump (blue arrow on A523) confirms the hot air will flow more directly into the cannon exit, IMO.
And it's probably there to manage external flow into the slide too.

The tunnel mouth is not an evolution of last year, it's a 90% redesign. Except the outer fence, a.k.a bargeboard, the top leading edge (yellow) & the fences (green) are completely different. The top is pulled up & very curved à la RB18. Fences angle & shape (& position) are new.

Maybe 90 sharp angle on top will facilitate some kind of vortex downstreamm. You can see small wings and fence just behind

Don't buy into my tubercles theory? :lol:

The waterslides on this year's alpine look very refined. I'm surprised they didn't reverted the sidepod inlets to start of '22 design though given almost everyone else is opting for high/wide inlets like they developed towards last year. Maybe we'll see them change at testing and this is just a placeholder

Did you mean didn't ?

They actually changed them. They're still very boxy, like they were at the end of 2022. The top corners of the inlet are still 90 degrees but the bottom outer corners are now greater than 90 degrees, forcing the bottom inner corners to less that 90 degrees and a slight slant in the bottom of that inlet.
I got confused at how they developed their sidepod inlets. No longer surprised by their development choice here :lol:

Yes the fences have a different shape but a similar angle to the French GP RB update
However this floor leading edge is closer to the early versions of the RB18 floor. More curvy/less flat

RB have ditched their double bargeboard arrangement at their floor edge. Will need more photos to 100% confirm but I believe they now use 3 of their fences for managing underbody flow, as the other teams also do

https://i.imgur.com/Sg17uGp.png

Silverstone to compare. You can see here they only use 2 floor fences under the floor, and 2 taller outboard fences. Probably the largest floor change RB have made since the start of the season.

But this floor edge seems to come straight outta Abu Dhabi 2022. Everything is there, at the same place (except the 'gurney flap' area which, it seems, has been cut away - red arrow)

Are they trying to form a downwashing cascade with the new front suspension location there

The way you are keeping track of the changes and evolutions is impressive, fantastic job!
