Red Bull RB18

The more videos and discussion that comes out, the more im thinking this years RB is another work of art! And still sounds like plenty of areas to develop

I think the containment & extra insulation around the brakes this year have to do with the fact that the hot air can only exit the back inisde off the wheel, the same side it enters on. How air is blown into the center of the hub, is forced out through the vent holes & channels in the brake rotor & then is captured & exits out the back inside rear of the hub.

Brings up an idea/question: Could it be useful to install a heating/cooling device on the brakes? it could help to heat up the tyres. For a restart or after new tyres, since they are not allowed to preheat properly.

RB look like they've manage to raise the rear crash structure/gearbox section within the diffuser, so it occupies less volume than others.

The following image offers a better comparison of the raised, rear crashed structure Red Bull are using with their RB18, in contrast to that used at Mercedes on the W13:

Looking at it again, it could be the RB uses a longer, shallower structure, while the Mercedes' is shorter but deeper, with the net result being a similar volume potential?

Has there been any news regarding the porpoising on the RB?

Thr beam wing of redbull seems to be more rearward, extending the size of the diffuser with a smoother transition compared to other cars where the beam wing sits directly above the diffuser.
Correct me if i am wrong ig the rules limit their relative positioning but based on the pics the redbull beam wing seems to be more rareward and has an almost tangential transition with the main diffuser. This will effectively increase the diffusers overall size.

Are the cars purposely sitting the rear end of the car to the ground at speed?
A few of the shots the care look lile theyre squatting to seal the floor more and increase ground effect. I dont know if its being done in the corners or on the straights.

The side of the floor isn't a straight reference anymore so it's hard to tell actual car attitude from most pics. Also the edges of the floor seem to be bending and physically sealing the ground.

He's claiming it's a pro-dive but I'm pretty sure that's not the case. My estimations put it at around 30% anti-dive.

Yeah definitely.

The old cars had settling effect from driving as the front wings moved lower, but that is not the cars for these cars. It is more important to keep the tunnel from "chopping off" segements of flow as it pitches and rolls.

Has there been any news regarding the porpoising on the RB?

In the Dutch article on nu.nl it is said that on the first Day porpoising was particularly violent at Red Bull, but after some tuning it settled. In an article that just appeared on gpblog.com about the rumoured aero pack for the W13 it is stated that the floor needs to be stiffened.

I suspect teams went to the limit in flexing floors in Barcelona and will have stiffer floors next test, stiffness based on the gathered data
