Red bull brings important developments:
The Austrian team introduces a series of major changes to its RB21 on the occasion of the Belgian Grand Prix. Moreover, one of the last major developments before focusing on 2026.
In Spa-Francorchamps, Red Bull has brought an update in five parts of its RB21. Furthermore, After a first salvo of changes made to the flat bottom in Great Britain. Nevertheless, the Milton Keynes stable now deploys a substantial batch of developments, centered on key areas of the single-seater.
The new features concern in particular the front fin. However, the inputs of pontoons, the engine cover, the front suspension and the rear fairings – with the desire to optimize support and thermal management, while ensuring global aerodynamic consistency.

A new front fin, fruit of continuous research – Red bull brings important developments
As we can see by comparing the lines of the green lines above, the first two elements of the front fin saw their camber and their impact modified to modify the distribution of pressures on the first two elements in order to improve the overall support.
“The front fin is the subject of continuous development, explains Paul Monaghan, chief engineer of Red Bull. Furthermore, We finish a version, but research in CFD and blower does not stop. Furthermore, ”
“If the gains identified in these environments – thanks to the great work of those who deal with it – are sufficient. then it justifies the manufacture of a new fin. This is what we decided to do, because we had time and financial means to manufacture it.”

Redesigned pontoons to reconcile cooling and performance
In order to better face the demanding circuits on the cooling plan, Red Bull has redesigned the entries of its pontoons (compare the areas indicated by the green and blue arrows). The two previous openings were merged into one, extended in its upper part.
Even if this development aims first to improve thermal control. Monaghan specifies that its advantages exceed the simple framework of reliability.
“What we have done at the level of the pontoons allows us to make a global performance gain, he says. We have made these changes because they provide a profit to the entire car. and therefore to our time on the Tour. In this sense, all these developments go in the same direction. red bull brings important developments They are not rustins. »»
The modification of the inputs of pontoons had a domino effect on the upper part of the body. The engine cover was adapted to align the air flows with the floor. while the rear suspension fairings have also been adjusted to integrate harmoniously into the new upper line.
Front suspension: adjustment to accompany the rest
Finally. as we can see above (yellow arrows), Red Bull has retouched the internal fairings of the front suspension, adding a little camber. This change. which is inspired by visible solutions on the McLaren MCL39, aims to optimize the air pressure available for the new inputs of pontoons.
It remains to be seen whether these improvements will be sufficient to allow Max Verstappen to shine on its. favorite circuit …
