During the Bahrain Grand Prix, both George Russell and Lewis Hamilton faced overheating issues with their power units, forcing them to adjust engine modes and driving styles in an attempt to manage temperatures. Despite their efforts, they finished in fifth and seventh positions, respectively.
Mercedes’ customer team, Williams, encountered similar challenges, while McLaren and Aston Martin experienced no such problems.
According to Mercedes’ technical director James Allison, the team is still investigating the root cause of the overheating issues, which came as a surprise given their accurate predictions for race day temperatures.
Allison explained that the team had to make educated guesses regarding cooling levels based on expected ambient temperatures, but despite their predictions aligning closely with the actual conditions, they still encountered significant temperature discrepancies during the race.
The consequences of overheating were detrimental, leading to throttle and engine mode adjustments to ensure engine longevity, resulting in compromised performance and tire degradation.
Mercedes’ trackside engineering director Andrew Shovlin confirmed the significant lap time loss incurred due to the overheating issues, estimating a loss of around one to three-tenths per lap. Shovlin also suggested that without the issues, both Russell and Hamilton could have secured higher finishing positions.
In conclusion, Mercedes is actively working to identify and rectify the underlying causes of the overheating problems to avoid similar issues in future races.
