Red Bull faces simulator correlation challenges, Verstappen concerns and rising development costs
After coming close to victory at its home race in Austria, Red Bull endured a far more difficult weekend at Silverstone. Not only did the team struggle to match the pace of its main Formula 1 rivals, but Max Verstappen’s race-ending incident—and his frustrated comments afterwards—also reignited speculation about the four-time World Champion’s future.
Technical director Pierre Waché attempted to calm the situation while acknowledging that Red Bull is currently dealing with several significant challenges. According to the French engineer, some of those issues extend well beyond Formula 1 itself and are influenced by external economic and geopolitical factors.
Silverstone exposed the RB22’s remaining weaknesses
The British Grand Prix highlighted structural limitations that Red Bull has yet to eliminate despite introducing several recent upgrade packages. Speaking to Auto Hebdo, Pierre Waché explained that the RB22’s balance problems were made even worse by Silverstone’s challenging conditions.
“During the race we weren’t able to completely solve our balance issue, and that limited our speed,” Waché explained. “The wind also caused problems, and there are still areas that we need to investigate.”
The team’s disappointing performance at Silverstone also revived discussions surrounding the FIA’s ADUO power unit rankings, which identified the Red Bull-Ford engine as the benchmark of the new generation.
However, Waché questioned that conclusion.
“I don’t believe we have the best internal combustion engine,” he said. “At best, we’re on the same level as the others. If we do have an advantage, it comes from cooling efficiency and energy integration, but those aspects aren’t taken into account. The more power we have available, the more freedom we have to develop the car with a lower level of aerodynamic efficiency.”
Max Verstappen’s feedback doesn’t always match simulator data
Following his retirement at Silverstone, Max Verstappen was openly critical of Red Bull, referring to a rear wing issue that had already appeared during the Austrian Grand Prix weekend.
According to Pierre Waché, one of the biggest challenges lies in matching simulator data with the sensations experienced by the Dutch driver behind the wheel.
“Max identifies things that affect him more than we sometimes imagine,” Waché admitted. “There are issues that don’t appear to be major problems in our simulations, but for him they are. He feels certain things through the steering wheel that we simply can’t reproduce in the simulator, even though the car’s overall potential there is exactly the same.”
The comments highlight one of Formula 1’s most complex engineering challenges: translating a driver’s highly sensitive feedback into data that engineers can accurately measure and reproduce through simulation tools.
Despite Max Verstappen’s frustration, Waché remains confident that Red Bull can still provide the type of car capable of convincing its star driver to stay with the team: “Max isn’t frustrated simply because he isn’t winning. The most important thing is that he’s convinced we can give him a car capable of winning races. And we can,” the Red Bull technical director insisted.
Development priorities already shifting toward 2027
With the summer break approaching, Red Bull has reached a crucial stage in planning its future development programme. Like every Formula 1 team, it must now divide its resources between improving the current car and beginning work on the 2027 project.
Waché acknowledged that balancing those two programmes will inevitably require compromises: “The biggest limitation for development remains our production and research capacity. Development of the 2027 car will begin very soon, and that will inevitably force compromises on the production side.”
As manufacturing capacity becomes increasingly stretched, Red Bull will need to carefully decide which new components deserve priority over the coming months.
Global conflicts are driving Formula 1 development costs higher
Beyond technical challenges, Red Bull is also facing a rapidly changing economic environment. According to Pierre Waché, international geopolitical tensions have dramatically increased the cost of raw materials, making Formula 1 development significantly more expensive under the FIA’s financial regulations.
“The increase in the cost of the materials we use has been extremely significant over the past few months and very difficult to predict,” Waché explained. “The conflicts in the Middle East and Ukraine have pushed up the prices of certain materials that are also used in weapons manufacturing.”
The dramatic rise in procurement costs has become one of the biggest obstacles facing Formula 1’s leading teams. Producing new aerodynamic or structural components without exceeding the FIA cost cap is becoming increasingly difficult: “Inflation for these products has exceeded 200%,” Pierre Waché emphasized.
For Red Bull, this represents a critical financial challenge at a time when competition at the front of the Formula 1 grid has become tighter than ever. While the team continues working to solve its technical issues and maintain Max Verstappen’s confidence, it must also navigate an increasingly difficult economic landscape that threatens to slow development despite operating at the very highest level of the sport.
