Red Bull RB8 Renault

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.

After all they will race B-spec
Interesting considering the limited running they had with it. Are they gambling a bit on this design?
they want performance no matter what happend. the car is good, but some teams are very close, but it might be just Newey's ego. he needs to be first in everything :roll:

the car is probably so much quicker that they can afford to investigate the B spec and still be a head even if the b spec is slightly slower.
For Sure!!

Also, the 'V' shaped centre of the diffuser, an area known as the boat-tail, has been exposed this year. In previous years this has been faired-in under the gearbox.

Overall, and perhaps unsurprisingly, the Red Bull iteration of the downwash sidepod is perhaps the most complete and logical downwash solution. However it's not a quantum step above McLaren's solution

Not if you consider how little aero performance the system in contributing even if it is the perfect design.

Look, the exhaust is going to get blown farther aft as the car goes faster. It is going to happen. Period. That being the case...

Do you ignore it and hope everything works out? That seems to be what you are suggesting.

Do you aim it ahead of the diffuser sealing area so there is less sealing at lower (the great majority of corners) speeds, and more (when the exhaust has been blown farther back into the sealing zone) at higher speeds? Not the choice I would make.

It appears Red Bull are going to carry their most recent package to Melbourne. It's about 3/4 of the way down in this Ferrari article.

"Meanwhile, Red Bull team boss Christian Horner told BBC radio on Wednesday that the team will take its updated car to Melbourne, despite its reliability and apparent handling problems at the final Barcelona test."

A suggestion from the Autosport forum:
I'm not sure I completely agree with that. Horner said that the concept was envisioned about a month before we saw it. It could be that RBR were always planning to blow over the diffuser but weren't exactly sure (hadn't settled on a firm idea) on how to go about doing so. Perhaps seeing what other teams were doing sparked an idea?
The Williams FW-16 (a Newey design) also had raised lower a-arms that were in-line with the drive shafts. That car had exhausts blowing into the diffuser and not over it, so the RB8's similar design doesn't necessary mean it was created to promote more efficient exhaust flow in that region, it could be simply for better all round airflow management.

All racing publications are pointing out the the latest iteration of the RB8 RW has slot gaps on it to improve performance.

Edit @Rikhart thanks for the extra picture the 1st picture sucks. :)

The point of rear wing slots was raised by an user here some days ago.
I agree with others with those "slots" being just reflections.I think they are reflections of the rear suspension arms. I see (cold be my mistake) the refletio of the pickup points

AutoSport. They claim, like Mercedes, RB RW has these slots.

What are the regulations regarding the RW's??

The top slot (the one that continues over the whole wing) has a slightly different shape on left compared to right. So imo they're reflections.

You make the diffuser as insensitive to it as possible!

No I'm inclined to agree that the picture above is a reflection. However that doesn't change the fact that many technical analysts saw the slots for themselves. The wing was only tested, not ran constantly.
