Red Bull RB18

Lovely lap from Max there.

Martin just said the RB can run the car with the floor touching the floor and not porpoising. Compared to the Merc which is clearly the worst at the moment.

Seems like Newey and the team have done a VERY good job from what we've seen

That grin from Marko and the rest of the team. This is looking to be a VERY GOOD car and todays upgrades have got it working simply lovely.

Definitely is exciting to be an RBR fan right now. Max and RBR 2022 champ is on the cards for sure.

Yep i knew this car was going to be a very refined one! Good job by the team.
It's very stable but lets see how much pace it has. It does not seem to have any weakness in the path that rhey havr chosen.

I read that a lot. And yes, porpoising was better controlled, but I have been watching live and to me the Merc still seemed closer to the ground. The closest off all.

Thank you! Reminds me of 2001...Rory Byrne introduced the one-piece-wishbone on the Ferrari F2001. But it was the lower wishbone. Renault and Minardi copied it in 2002, and if my memory does not trick me Ferrari and Renault used this untill 2006. Maybe Newey remembered this idea and made use of it and adapting it.

IIRC those one-piece wishbones just used a single flexure, but were functionally independent.

This RBR design looks like it will act as a spring.

Could that top arm also act a steering arm or camber arm?

It looks to me like it can transfer load from one side to the other causing camber changes in high speed corners.

So for instance, the rear/bottom arm is fixed & the top arm is floating in it's fixture inside the nose? Maybe with bumpstops to control how much change is allowed? Is that what you mean?

Thats not 100% correct. I talked to a Ferrari engineer of this time. Their one piece lower wishbone had a single flexure, but was built in a way such that it actually had dampening characteristics.

Yes along those lines where it takes a lot of load to get displacement but it does displace even minutely.

Then you watched another pre-season test than me. Mercedes was not closer to the ground than Ferrari or Red Bull. And definetely not the closest of all.

It's bolted through to each corner of the bulkhead. So you'd need either compliant gaskets somewhere or a mechanism to allow the anchor points to pivot. I'd guess free movement laterally of the arm would not be advantageous and only add instability. Image of anchoring point:

could say the RB was on the floor, the typical sparks out the back from the floor pan like we seen last year.

On a daft note, maybe could use that as a artificial bump stop to stop the porpoising on some other cars.

We were watching different things then. Merc is so close to the ground that when porpoising the whole side of the floor literally is on the ground.



Redbull was much more stable but always a few centimeters of the ground:

I'm afraid this is not a very rigorous analysis. You can't just pick one video where the Merc is in a high speed right hander rolling and dragging on the ground, and then find another video of the RB going in a straight line. All cars are skirting the floor depending on the corner, roll angle, bumps etc. The RB floor also is seen to be skating along the ground in many corners as the body rolls.
