Pink Bull Racing’s rise through the second half of the F1 season has been, to make use of Laurent Mekies’ personal phrases from Singapore, “spectacular”. For the reason that summer time break, Max Verstappen hasn’t completed decrease than second. The pure tempo wasn’t there in Zandvoort, however from then on, the shape has been spectacular: three wins (Monza, Baku, and Austin) and a dash victory.
It confirms that Pink Bull’s resurgence isn’t restricted to 1 particular sort of circuit. After triumphs on two low-downforce tracks, Singapore was anticipated to be an actual take a look at. Then got here query marks over the medium-speed corners in Austin – but Pink Bull handed all these assessments. Admittedly, the pure race tempo in Texas wasn’t significantly better than McLaren’s – or Lando Norris’ – however the truth that Verstappen might at the very least function on the identical stage already marks an enormous distinction to earlier within the 12 months.
The important thing query, after all, is what lies behind this turnaround. Verstappen admitted in Singapore that the brand new ground, launched in Monza, has helped – however mentioned it wasn’t the primary issue.
“It’s extra a few completely different philosophy,” he mentioned. That new philosophy partly issues how the group operates earlier than and through a race weekend: listening extra to the driving force, relying much less blindly on knowledge. However that’s not your complete story. Mekies and senior advisor Helmut Marko have each added that it’s additionally about how Pink Bull “runs the automotive”, and that individual ingredient is attention-grabbing.
Stella would “wager his greenback” on trip top understanding
In the course of the Austin weekend, McLaren group principal Andrea Stella shared his principle about Pink Bull’s progress. A part of the reason, naturally, is that Pink Bull continued growing its 2025 automotive longer than McLaren, however in response to Stella there’s extra.
“I feel if they’ve improved their automotive, it’s as a result of they could have fastened some potential aerodynamic points,” Stella mentioned. “We all know, like I mentioned earlier than, that there was a brand new ground in Monza and a brand new entrance wing in Singapore. And in addition, I feel their drivers appear to be far more vocal about trip and about grounding. So it could possibly be that they’ve merely understood that this technology of vehicles and their very own automotive as nicely must be run difficult some features like trip heights. For me, if I wanted to or if I needed to speculate, this is able to be the place I might put my $1.”

It’s well-known that ground-effect vehicles should run as little as doable – and with significantly stiff suspension – to extract most efficiency. Greater than 60 p.c of the entire quantity of downforce is generated beneath the automotive’s ground. A decrease trip top will increase the suction impact of the bottom impact and, along with the ground edges, helps to seal the airflow beneath the ground to take care of optimum stress variations: decrease stress underneath the ground, larger stress alongside it. These fundamentals have lengthy been understood, however Stella’s impression is that, because of the Monza ground and a greater grasp of methods to use it, Pink Bull can now run with decrease trip heights than earlier than – unlocking extra potential from the RB21.
The best image: unlocking rear downforce and entrance plank put on
This ties into an attention-grabbing speaking level of final weekend – given the bumpy nature of the Circuit of the Americas: plank put on. As a result of trip top is so essential, many groups attempt to run as little as doable, although there’s a restrict. After any race, the FIA can verify plank put on and the skid blocks (the titanium plates that create sparks). These checks are made utilizing 4 measurement holes in prescribed places on the plank, in step with article 3.5.9f of the technical laws.
After a race, the plank should nonetheless measure at the very least 9mm thick at these factors, that means it might put on not more than 1mm through the race. That restrict applies to the measurement holes, that means different elements of the ground can theoretically put on extra – so long as these zones move inspection.
In keeping with Sauber sporting director Inaki Rueda groups have made (various) progress in reducing trip top with out breaching these put on limits. Curiously, completely different groups put on completely different elements of the plank extra closely – which can also be seen within the FIA measurements. Most groups expertise the best put on on the rear half of the plank, however McLaren has for a while already managed to put on the entrance of the plank extra — which has a number of advantages.
“It’s inherent within the automotive, however there are some mechanisms by which – with the stiffness of the suspension – you attempt to make it in order that your weak level would not get as loaded as doable,” Rueda defined in Austin. That, he mentioned, is essential.
“Whichever group has managed to place it to the entrance, which means they’re truly in a position to run the automotive decrease than the remainder of us. So, that is one thing fairly intelligent. Whoever has managed to shift that put on to the entrance might be in a position to run it decrease than the remainder of us, and thus get a aggressive benefit.”
It’s instantly linked to how the ground works and the place it generates most of its downforce. “Precisely, as a result of many of the downforce comes from the place the driving force is sitting in direction of the again. In order that’s the place you actually need the ground to be near the bottom. But when your major level of damage is again there, you might want to elevate the automotive at that time, and then you definitely lose downforce at that time. And sure, loads of design effort has been spent on making an attempt emigrate that put on to the entrance, as a way to run it low. However it’s not a straightforward activity.”

That problem hyperlinks to the suspension and kinematics. “It’s troublesome to maneuver the wear and tear ahead due to the truth that the precise downforce is generated within the rear. So, you might want to discover a means that you just’re nonetheless operating all of the downforce on the again, however that your major level of contact is on the entrance.”
That, in essence, is the puzzle each F1 group faces underneath the present laws. McLaren was first to attain that ahead put on shift, however paddock solutions point out that Pink Bull has at the very least made steps to decrease the trip top in latest weeks as nicely – permitting it to extract extra from the RB21.
Marko confirms trip top principle, Mekies extra cautious
When Motorsport.com requested Helmut Marko about these trip top theories within the paddock – and whether or not the evaluation is appropriate that Pink Bull can now certainly run the automotive a bit decrease than earlier than – the Austrian smiled: “It is not a fallacious one.”
It suits in with what Pink Bull has been saying in latest weeks: improved understanding of methods to function the automotive and the introduction of the Monza ground have been key to the improved kind. Requested whether or not such trip top progress would have been doable with out that new Monza ground, Marko replied: “It would not have been with such an impact.”
Workforce principal Laurent Mekies, nonetheless, prefers to stay cautious.
“I would definitely not be capable to pinpoint one single ingredient, comparable to one improve or one set of things,” he replied when requested by Motorsport.com. “I feel will probably be largely minimising the superb evaluation job that has been accomplished to attempt to establish the place the untapped areas of efficiency have been, and the hassle to place the automotive in these areas and to see if it was going to carry out. It is not a mix of 1 issue, it is a mixture of many, many components.”
“We do not have a giant incentive to elucidate to anybody what it’s, nevertheless it’s a mix of all that. And naturally, each hundredth counts and the Monza ground has helped. Each single small element that we have placed on the automotive has helped, whether or not it’s mechanically or aerodynamically. And this, along with that intensive exploration of the place to run the automotive, has helped us on the efficiency.”
Learn Additionally:
Whereas Mekies is correct that fashionable Components 1 is simply too advanced to scale back to a single trigger, the ground and trip top that comes with it stay elementary to a automotive’s efficiency. And on that entrance, Pink Bull seems to have taken a big step after the summer time break, via each the Monza ground and a clearer understanding of methods to use it with out disturbing the general automotive steadiness.
That progress has helped Pink Bull discover the RB21’s working window extra persistently than earlier than, and unlock efficiency that in response to Verstappen had been there for longer – at the very least to some extent. Whether or not that step ahead has are available in time for a fifth consecutive title stays to be seen – nevertheless it has unquestionably made Pink Bull a serious power once more after some troublesome months. In truth, over the previous 4 race weekends, it’s accomplished much more than that.
