The Mercedes AMG F1 team grapple with persistent problems ahead of Australian Grand Prix but for now it appears little can be done to solve their biggest problem. As the Formula One circus heads to Melbourne for the Australian Grand Prix, Mercedes face a conundrum that has plagued their performance in the early stages of the season.

Despite high hopes for their new W15 car to close the gap on leaders Red Bull, a series of challenges at the Saudi Arabian Grand Prix highlighted the work that still needs to be done. The former German powerhouse is now deciphering data clues to address these persistent issues, but clear solutions remain elusive.

 

The bouncing dilemma

The 2022 season saw the introduction of cars designed to generate a significant proportion of their downforce through ground-effect aerodynamics. This design philosophy, which aims to promote closer racing by reducing the reliance on aerodynamic elements that disrupt the airflow of following cars, brought back a phenomenon not seen in F1 for decades: bouncing.

Mercedes, among others, found their W13 car severely affected by this problem, where at high speeds the car would begin to bounce vertically due to the alternating creation and loss of aerodynamic load underneath the car. This not only resulted in a loss of performance, but also raised concerns about driver safety and comfort, with Lewis Hamilton and George Russell frequently commenting on the physical toll it took to drive the car in such conditions.

 

 

Efforts to combat bounce

Throughout the 2022 and 2023 seasons, Mercedes waged an exhaustive battle against bouncing, implementing numerous updates and adjustments to mitigate its effects. Despite their efforts, the team often found themselves at a disadvantage to their rivals, particularly Red Bull, who seemed to have mastered the new regulations more effectively.

The bounce issue not only hindered lap times, but also limited the drivers’ ability to get the most out of their cars, leading to inconsistent results and a struggle for race wins and championships, in stark contrast to Mercedes’ dominant form in previous years.

 

 

 

A bold new direction for 2024

Recognising the need for a radical departure from their previous design philosophy, Mercedes undertook a comprehensive redesign of their car for the 2024 season. The team’s engineers and aerodynamicists went back to the drawing board and developed the W15 with the primary goal of eliminating the porpoising problem while maximising the potential of ground-effect aerodynamics.

This new design approach represented a significant gamble, as the Mercedes team produced a car concept that was much closer to the Red Bull car of the previous year. Certainly, the result has improved on the problems of previous seasons, but a new ugly problem has been discovered since the start of the 2024 season in the Middle East.

Unravelling the mystery behind Mercedes problems

Mercedes’ optimism for the 2024 season, bolstered by the introduction of the W15, was met with a reality check in Jeddah. The team’s performance lagged behind not only Red Bull, but also McLaren and Aston Martin.

A huge problem was identified with the W15 struggling in high speed corners. This unique problem, characterised by bouncing and a consequent loss of downforce and grip, has been identified as the main culprit behind the team’s time deficit on track. This is not good news for the former F1 juggernaut.

Team Principal Toto Wolff has insisted that the W15 is competitive outside of these high-speed sections. The problem appears to be isolated to certain parts of the track, where the car’s smaller rear wing and adjustments made to compensate for the lack of cornering ability are not enough to close the gap.

Data analysis sheds light on performance gaps

Further insight into the W15’s problems was gained by comparing GPS data from Mercedes’ qualifying sessions in Saudi Arabia in 2023 and 2024. The analysis revealed a significant drop in speed through a crucial high-speed section, with George Russell, the fastest Mercedes driver in these instances, having to lift significantly compared to the previous year.

This lift resulted in a significant loss of time which, although partially recovered in later sections of the lap, underlined the critical nature of the car’s high-speed cornering issues.

Challenges in diagnosing and solving the problems

Mercedes’ efforts to identify and resolve the W15’s shortcomings were complicated by inconsistencies between track performance and simulator predictions. An issue that has plagued the Ferrari team over the last several seasons past.

The unpredictable loss of grip, which affects driver confidence, has not been attributed to a single cause. This inconsistency, which varies between qualifying and race conditions, adds another layer of complexity to the search for a solution.

Andrew Shovlin, Mercedes chief engineer, noted the variations in the car’s behaviour with changes in fuel load, indicating that the team’s understanding of the W15’s dynamics is still evolving. The Melbourne circuit, with high-speed corners similar to those that caused problems in Saudi Arabia, is the next litmus test for Mercedes’ ongoing adjustments.

Cautious optimism for Melbourne

As the team prepares for the Australian Grand Prix, “experiments” are reportedly being planned, including a possible review of the underbody configuration used in the Bahrain tests. This strategic pivot is aimed at determining whether recent upgrades have inadvertently exacerbated the W15’s high-speed cornering issues.

With the spotlight on Mercedes in Melbourne, the team is acutely aware of the urgency to address the car’s particular weaknesses. This weekend not only offers a chance for redemption, but also serves as a crucial juncture to validate the effectiveness of Mercedes’ problem-solving approaches. An aspect the team has been sorely lacking in over the last couple of years.
