Red Bull RB22

Something that I noticed was the reduced size of the cooling outlets in Miami compared to Bahrain.

Is there an analysis behind those innovative sidepods and the difference than the rest? Also are there comparison pictures with the previous ones?

do you have pics of the main exit at the rear, how different was it in Miami w.r.t Bahrain (hot v hot) ?

In Bahrain there were louvers in the side next to the driver. In Miami I noticed that it was a bit less than what Ferrari used.

This is really encouraging. The 'benchmark' in this regard is McLaren. If track-to-track, the RB22 has 'cooling exit area' comparable to McL40, that will be the 'tell' that Redbull have solved their cooling issues.

Yes, it is I feel one of the 'issues' they have been able to solve:

- Starts & other engine gremlins (not fully solved yet, although progress made, maybe counted as solved?)
- (cooling) efficiency (solved - less louvres / smaller rear exit,new macarena rear wing, intake/sidepod)
- balance in yaw (probably due to insufficient out-wash to ingress of rear wheel wake into diffuser) (solved via new sidepod, but also front wing?)
- weight (not yet solved)
- low speed mechanical grip (partly solved, maybe new suspension will follow if that is the rumour)

We can add the solved steering issue to this list as well.

I was also wondering if any weight came off with these updates but apparently not. If they can get that 30kg out of the car then the others won't know which way to look.

How could anyone possibly know the weight without another sneak video?

I believe that Wache said they are still to find any weight loss gains.

Really ? if the peformance upswing in Miami was without saving weight from Japan, then I think RB22 would become the fastest car purely by weight saving (when others are near the weight limit) with a big margin. That sounds too unrealistic. Which means there indeed was weight saving in Miami.

They were able to reduce from ~12kg to 6-7kg overweight with the Japan and Miami upgrades. How much in Miami is not clear, but with all these new parts it is almost certain they were able to reduce it further with the Miami upgrade.

Wache said they will bring the final weight reduction update to Austria.

Can there be weight reduction in the PU? or it completely homologated and cannot be changed?

I think the flip-wing came with a weight penalty...

Is there a clear reason why the bib concept with the isolated forward section that was adopted in miami (a similar design to the launch spec SF-26) is advantageous under these rules?



Does it exploit a loophole or is it more a choice around flow conditioning ahead of forward floor/fences

Do you have a link to where that information is given?

I would say that primarily it is a conditioning device for when yaw is present (in that location steering lock can cause local yaw conditions even when the car is, fundamentally, in a yaw neutral state.
