Adrian Newey confirms the (lower) rake on the RB18 as well
We told you in pre-season that the rake set-up, the higher ground clearance of the rear compared to the front, would still be present on the ground handling cars, albeit much less exaggerated. While Ferrari is adopting a more neutral set-up - and this also helps in having a more balanced car that is easier to tune immediately for the start of the weekend, Adrian Newey is sticking to his ideas and has reintroduced a minimum rake angle on the RB18 as well. It's a complex concept to apply, as cars of this generation need to stay very low and seal the flows below the bottom, in the Venturi channels, to maximise the overall downforce.
This technical choice guarantees an attenuation of the porpoising effect. In fact, a greater incidence of the rear from the ground means that it takes longer for the rear to touch the ground and reach the point where the flow breaks. This is one of the reasons why the Red Bull suffers less from porpoising than others. One engineer confided to us that "Red Bull runs with a fairly pronounced rake for a ground effect car. This alleviates the porpoising and also allows them to travel with somewhat less loaded set-ups'.
The second advantage is better agility in the slow-moving area with a pace that is more 'shortened' than that of a more neutral car. A third aid is one that could help limit understeer. Max Verstappen, like Leclerc, loves having a precise front end and a rear end to manage. Opposite driving styles, curiously enough, to those of their respective teammates; Carlos Sainz and Sergio Perez are better able to manage a stable rear end but a more understeering front end. The overweight with which the RB18 began this season has clearly prevented the team from optimising the weight balance, which has therefore repeatedly led to the car suffering from pronounced understeer, which, thanks to the slimming treatment carried out between Imola and Spain, has allowed the RB18 to improve considerably from that point of view, especially in the race with the 110kg of petrol on board.
The downsides of such a choice are that of losing a little load in fast corners and a slight increase in drag that worsens petrol consumption in the race, although the RB18 compensates with the macro features of the design that go precisely towards improving this 'problem'.
Not a single word in this article came from Adrian Newey.

It will move forward if the diffuser is contributing less relative to the rest of the floor as the rear comes down.
I agree that rake helps against porpoising. It quite logical, as one of the "tools" against porpoising is a higher ride height. With rake, you run the car with a higher ride height at the rear, so of course this will help against porpoising.
Maybe RB will use this wing on one of the cars for test purposes, because this seems pretty high DF and very un-red bull for a track like Silverstone. Wouldn't surprise me if they eventually will run less DF.
Does look a bit more downforce related than the others. Maybe it will tie in with the calculations for the high speed corners like Maggots and Becketts where they might think a lower downforce wing wont allow them to go full throttle with this era of cars.marcel171281 wrote: ↑Thu Jun 30, 2022 11:41 amMaybe RB will use this wing on one of the cars for test purposes, because this seems pretty high DF and very un-red bull for a track like Silverstone.
