Ferrari recently conducted tests on the FIA’s experimental spray protectors at their test track in Fiorano. The car used for the tests was equipped with visually more prominent wheel covers compared to the version previously tested by Mercedes. Another Ferrari car, in its conventional form, also ran alongside the test car to evaluate visibility. The goal of these tests is to assess the effectiveness of the ‘Wet Weather Package’ (WWP), which is a set of specifications designed to improve visibility in wet conditions. The WWP aims to prevent a repeat of the 2021 Belgian Grand Prix, where the race result was determined based on a single lap under the safety car. This latest Ferrari test is part of the data collection process to enhance the WWP and ensure it accurately simulates wet conditions on the track.
The initial version of the WWP, tested by Mercedes and driven by Mick Schumacher at Silverstone last year, generated more spray than desired. The wheel covers used in that test were relatively compact and in two sections. To address this issue, the FIA decided to explore a second version of the WWP that provides more coverage for the wheels. That is why Ferrari used the bulkier versions of the WWP during their recent test. The result of this test will play a crucial role in shaping the FIA’s ongoing efforts to develop an effective WWP.
Nikolas Tombazis, FIA Single-Seater Technical Director, stated that the May test is not the final solution for the WWP. He mentioned that, if everything goes well, the WWP could be implemented in 2025 as part of the new regulations. However, if the test does not produce satisfactory results, the FIA may need to reconsider its approach. One of the key questions that the FIA needs to answer before finalizing the WWP is whether covering the wheels can significantly reduce spray, ideally by around 50%. It is important to note that a significant amount of spray is also generated by the diffuser, which cannot be closed for aerodynamic reasons. Therefore, it is not expected that the WWP will completely eliminate visibility issues caused by wet conditions. The FIA aims to find a balance between improving visibility and maintaining the simplicity of the regulations.
In conclusion, Ferrari’s recent test of the WWP represents another step in the development process. The FIA is actively working to collect data and refine the WWP to ensure that it accurately addresses the challenges of wet conditions in Formula 1. The ultimate goal is to find a solution that significantly reduces spray while maintaining the necessary aerodynamic performance of the cars. The final implementation of the WWP still depends on further testing and evaluations, with the hope of incorporating it into the regulations by 2025 or 2026.
