Red Bull RB9 Renault

Raaaakkeeeeeee!

[gandharva]

- reworked beamwing (middle part) with huge gourney flap
- DRD mounted and slit/inlet opened
- reworked diffusor shark-fins (only two fins instead of three)

Wow, the tunnel is pretty impressively reworked. More of a bridge now than a tunnel.

For me, the tunnel looks exactly identical to the one used in Jerez.

is the pipe blowing over the wishbones not a re-directing of the lateral cooling exits? They seem to be missing.
Could it make sense for them to no longer blowing sidepod exits over the top of the diffuser?

It seems due to Williams launch allot of the new parts on red bull have been overlooked. Im seeing what look like new tunnels close to the floor at the back from overhead shot. my eyes may be paying tricks though. There seems to be a number of changes on the back end. anyone have any pics?

Anyone knows any meaningfull reason as to why would they run with such high rake?

The rake is visible evidence of a car that can seal the diffuser edges very effectively with the exhaust gases. When this effect is achieved the rake can be increased which effectively increases the diffuser size. Without the sealing effect of the exhausts at the diffuser edges this amount of rake would cause the air under the car to spill out of the sides of the diffuser and also the tyre squirt would corrupt the flow therin. However, the exhaust gases are directed down between the rear wheel assembly and the diffusor edge to create a wall of high pressure gas preventing diffuser flow leakage and tyre squirt contamination. Clever hey?

Maybe the lights playing tricks with my eyes, to me, it looks like there's an exit under the EN of RENAULT.

Thanks! Does look wierd though.

Ya mean the little patch with 2 screws?

Hm, can't see any outlet in this area.

is it possible that under this little cover (see red circle) is a different attachment point for the upper wishbone (to generate a different rear geometry)?
if not, what is this cover used to be?
