Formula 1: The Impact of Upgrades and Performance Troubles in the 2025 Season

The 2025 Formula 1 season has brought plenty of excitement and drama, especially as teams like Mercedes and Ferrari continue to push the boundaries of innovation and performance. The Hungarian Grand Prix, one of the most anticipated races on the calendar, provided some intriguing insights into how teams approach upgrades, and what happens when those improvements don’t go according to plan.

Mercedes’ Challenge with Upgrades

Mercedes, under the leadership of Toto Wolff, has faced its fair share of challenges during the European leg of the 2025 season. For much of the early part of the year, the team appeared to be making impressive strides, with George Russell securing four podiums in six races. His rookie teammate, Kimmy Anteneelli, also showed promise, including a sprint pole in Miami and a stunning performance in Melbourne, where he surged from P16 to P4. These results suggested that Mercedes was on the right track as the team worked to close the gap to the front runners, Red Bull and McLaren.

However, things took a turn at the Emilia Romagna Grand Prix when the team introduced a new rear suspension configuration. This change, which Mercedes had hoped would give them the performance boost they were after, instead resulted in a significant downturn in results. The new suspension setup proved to be a costly mistake, and the performance struggles were clear as Mercedes faltered in the following races.

Toto Wolff, ever candid about his team’s challenges, explained that the new suspension had failed to deliver as expected. He acknowledged the complexity of the modern Formula 1 car development process, which is heavily reliant on simulations and data analysis. Yet, despite the advanced technology, there are moments when the correlation between the digital world and real-world performance simply doesn’t align. Wolff admitted that sometimes, after all the digital simulations, a component needs to be physically tested in the car to truly understand its effects on performance.

In the case of the new rear suspension, it became clear that it didn’t deliver the desired results. As Wolff put it, the part “will end up in a bin somewhere,” referring to how the team had to revert to their previous configuration. Fortunately for Mercedes, the decision to go back to their older rear suspension in Hungary paid off. George Russell managed to return to the podium, marking a strong result for the team after a difficult spell. Wolff emphasized that the key takeaway from this setback was not the loss of performance, but rather the fact that they had identified the cause of their issues. While rivals continued to upgrade their cars, Mercedes was still fighting for podiums, showing that even with setbacks, they remained competitive.

Ferrari’s Struggles with the Charles Leclerc’s Performance

On the other side of the paddock, Ferrari had their own set of problems during the Hungarian Grand Prix, this time centered around Charles Leclerc. Leclerc’s weekend started off strongly as he qualified on pole, showing that Ferrari had a car capable of challenging the top positions. His performance in the early stages of the race suggested that the team had a competitive edge over McLaren, who had been a strong contender throughout the season. However, things took a dramatic turn during the race, as Leclerc began to lose pace significantly as the race went on.

By the latter stages of the Hungarian Grand Prix, Ferrari’s pace had disappeared, and Leclerc was left struggling to keep up with the McLaren drivers. The cause of this sudden drop in performance was not immediately clear. Leclerc speculated that it might be an issue with the chassis, and Ferrari began investigating to determine the root cause. While the team continued to analyze the data, George Russell, who had a front-row view of the situation, offered his own thoughts on what might have gone wrong.

Russell noted that Leclerc’s Ferrari might have been running too low to the ground, which could have contributed to excessive wear on the tires and other components of the car. This could explain why Ferrari was forced to increase tire pressures in the later stages of the race. The issue might also have been compounded by Ferrari’s use of a specific engine mode that slowed the car down on the straights, resulting in further struggles.

Interestingly, the FIA conducted random inspections on several cars following the Hungarian Grand Prix, including Leclerc’s Ferrari. These inspections focused on the skid block, a part of the car that is crucial in monitoring how low the car is running relative to the track surface. The FIA revealed that three cars, including Leclerc’s, had been selected for these tests, and all passed without any issues. This meant that Ferrari’s chassis height was within the permissible limits, but the underlying reasons for Leclerc’s poor performance remained unclear.

Ferrari’s chassis-related issues had already been a topic of conversation earlier in the season. After the Chinese Grand Prix, Lewis Hamilton had been disqualified for excessive wear on his skid block, highlighting how critical it is for teams to maintain the correct car setup. For Ferrari, it seems that their difficulties in Hungary were the result of a combination of factors, rather than a singular mechanical failure.

The Importance of Testing and Data in Formula 1

Both Mercedes and Ferrari’s struggles during the Hungarian Grand Prix highlight a crucial aspect of modern Formula 1: the importance of testing and data correlation. In an era where performance is largely driven by simulations and digital models, there can be a significant gap between what the computer says and how the car performs on track. This issue becomes particularly evident when new components, like Mercedes’ rear suspension, are introduced without the desired outcomes.

For Mercedes, the process of testing and reverting to an older configuration underscores how teams must remain flexible in the face of adversity. Even when technology points in a certain direction, it is the real-world testing and feedback from drivers that ultimately provide the best insight into what works and what doesn’t. Similarly, Ferrari’s ongoing investigation into Leclerc’s performance emphasizes the delicate balance between theoretical data and on-track realities.

Conclusion

As the 2025 Formula 1 season progresses, teams like Mercedes and Ferrari continue to face the constant challenge of upgrading their cars to stay competitive. For Mercedes, the Hungarian Grand Prix proved to be a turning point, with the decision to revert to an older suspension configuration paying off with a podium finish. Meanwhile, Ferrari’s struggles with Leclerc’s pace remind us that even the most seemingly minor issues can have a significant impact on performance.

Ultimately, Formula 1 remains a sport defined by constant development, testing, and adaptation. While digital simulations and cutting-edge technology drive much of the innovation in the sport, it is the real-world testing and feedback that determines whether a car is truly ready for the track. As the season continues, it will be interesting to see how both teams address their issues and whether they can continue to fight for podiums as the competition heats up.
