First look at FIA’s ‘spray guard’ design to improve wet weather visibility
The FIA has issued images of the ‘spray guard’ design it is testing as it seeks to improve the visibility problems drivers encounter in wet races. The problem has become especially severe in Formula 1 where several races have been disrupted by poor weather in recent years. The Japanese Grand Prix at Suzuka was disrupted by a downpour last year and in 2021 the Belgian Grand Prix was abandoned after just three laps behind the Safety Car due to persistent heavy race at Spa-Francorchamps.
The FIA is seeking a solution which can also be used in junior categories of single-seater racing. The danger of racing in wet conditions was highlighted in a crash at Spa three weeks ago which claimed the life of Dilano van ‘t Hoff. FIA president Mohammed Ben Sulayem announced last year the governing body had begun investigating whether a bodywork package could be added to F1 cars in wet races to reduce the spray they generate and improve visibility. Mercedes and McLaren participated in the first track test of the design at Silverstone last week.
The bodywork is installed behind and above each of the car’s four wheels. It is intended to cut the amount of water thrown into the air by car tyres, which can displace huge volumes of water on a wet track. While teams have welcomed the FIA’s efforts to improve safety in wet conditions, Mercedes’ trackside engineering director Andrew Shovlin said the first test indicates more work is needed on the design. “They’re not ready to be moved into production and regulation at the moment so there’s definitely work to do,” he said. “They do improve the spray that you get from the tyres, but you still get a lot coming from the diffuser and the way that the rear wings are pulling it up.”
