Alfa Romeo Sauber F1 C37

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.

Flow separation on the sidepod behind the bargeboards or is it just the paint that’s not been applied well?

Is there any detailed photo of S duct exit? What is going on there? It seems like it have two exits.

Swedish reports, citing Sauber sources, claim that the aero updates they bring work well, however the car is inconsistent through corners, that it can switch from understeer to oversteer and then back again through a single corner.

That's a wing that is... not working well.

That’s a lot of separation. Compare it to wings that are actually working well:

Makes me wonder how they can hope to get the rest of the car working if they get something as important as the RW completely wrong.

That separation may be one of the reasons for an unstable performance trough corner.

Do notice there is no Gurney flap on that wing and neither a V slot for vortice generation, so it's not that surprising to see this kind of separation. G-flap and v-slot will help with that, but only the team knows if it will completely prevent separation.

And they call it a stall. A STALL!

If you are speaking about air separation, is that the blue area indicated in below image?

No - the top edge of the wing. The curly mess of flowvis indicates that something like this is happening

That little eddie is causing both drag, and loss of downforce, as it's slowing the air under the wing, and increasing the pressure.

Wing's working fine. DRS can cause flow separation at that point.

I don't buy that - mostly because you don't see this on other team's wings, as shown above by the Mercedes flow vis.

I've never seen a team apply flowviz and test their DRS flap...
