Though the squad has had no scarcity of wins within the meantime, that didn’t imply it was going to take a seat again and settle for a repeat of what occurred at Interlagos 12 months in the past which had opened the door for Mercedes.
While the RB19 clearly has a a lot bigger efficiency delta over the opposition than its automobile had final season, there have been clear classes that it took from 2022 that have been utilized this day out.
The obvious from the surface is that if we evaluate the rear and beam wing configurations from the RB18 and the RB19.
They present us a shift of strategy in how downforce on the rear of the automobile is balanced between the beam and rear wing – which is completely different to 12 months in the past.

As could be seen above within the comparability picture, the rear wing structure has modified already this season, with a wider central span for the mainplane earlier than it tapers to a extra tightly wound transition with the endplate.
However the peak of the higher flap stays fixed throughout its span, with a teardrop-shaped flap pivot employed to assist circulation distribution because the flap merges with its open-ended tip part. That is one other new function this season to assist commerce downforce and drag.
Crimson Bull additionally opted for certainly one of its larger downforce beam wing configurations in 2022 and, while it nonetheless employed a double ingredient possibility this season, it’s clear to see that it was a way more unloaded variant.
Chief engineer Paul Monaghan mentioned it was fascinating that there gave the impression to be a diffusion of downforce ranges throughout the sector – however there have been different parts that Crimson Bull had modified for this yr.
“There is a affordable unfold on this discipline, from what I can inform, of various downforce ranges,” he mentioned. “And if you happen to select to have a look at the photographs of final yr’s automobile and this one, one will stand out fairly nicely.
“The subtleties of how we have chosen to function the dimensions is completely different from final yr. That is our personal alternative and you may see the implications there.
“The modifications, imagine it or not, are literally fairly delicate. It isn’t a form of: ‘Oh my God rip all of it up and begin once more.’
“However the good factor is all of the theories that form of surrounded final yr’s efficiency right here appear like they’ve borne fruit.”

124-23 Crimson Bull Diffuser comparability
As rivals proceed to look at simply why the RB19 seems so good, there was an growing concentrate on its ground and diffuser design – as that is such a essential space for automobile efficiency.
One fascinating facet famous this season was the change Crimson Bull comprised of the Spanish Grand Prix, with the higher nook of the diffuser pinched inwards (pink arrow).
This was an concept that took inspiration from what Williams had finished, exhibiting that no crew ought to ever ignore what slower rivals are as much as as they will have some fairly good concepts.
This pinch concept has an influence on the airflow and stress distribution each contained in the diffuser and externally because it flows into that nook. It additionally required the crew to seek out the correct geometries not just for the pinched part but in addition the diffuser’s sidewall and the ramped ceiling (beneath).

The change made to the ceilings contours could be seen within the right-hand inset (above), with a narrower however longer growth channel close to the trailing edge.
With a view to accommodate this extra quantity inside the diffuser, concessions need to be made on the ground’s higher floor too although, with a wedge-shaped blister fashioned (left inset).
