Shanghai, China – Formula One teams faced unexpected challenges during a recent circuit inspection in Shanghai due to a new surface treatment. The teams, which had prepared extensively based on information provided by Pirelli and the FIA, were surprised upon arrival to find a visibly different track surface.
Drivers likened the appearance of the track to having been “painted,” signaling a significant change from the previous surface conditions. It was later revealed that a liquid bitumen surface treatment had been applied the previous year to minimize asphalt degradation, resulting in a two-tone appearance due to wear in certain areas.
The altered surface not only changed the track’s visual appearance but also had a notable impact on grip levels. The uneven distribution of bitumen led to variations in grip between sections where the treatment remained intact and those where it had worn away, adding a new layer of complexity to the racing conditions.
Despite typical procedures involving the FIA’s notification of any significant track alterations, teams and Pirelli were not informed about the surface treatment in advance. This lack of communication raised concerns among team managers during a meeting with F1 race director Niels Wittich, who defended the decision not to notify teams, citing the treatment as a non-material change.
The issue of communication regarding track alterations highlighted the need for improved transparency between circuit operators, the FIA, and F1 teams. Moving forward, there is a call for closer collaboration to ensure that any modifications to track surfaces are adequately communicated to all stakeholders to prevent surprises and facilitate better race preparations.
While the grip changes resulting from the surface treatment were not as drastic as seen in previous instances, such as the Turkish Grand Prix in 2020, it underscored the importance of clearer communication and collaboration in maintaining track integrity. Shanghai plans to address the surface treatment concern by undertaking a comprehensive resurfacing project before the 2025 race, aiming to eliminate uncertainties and provide a more consistent racing experience for competitors.
