Pictures from the test showed Arthur Leclerc driving the 2023 Ferrari SF-75 with fully covered front and rear full-wet tires. The guards had two holes in the front but were completely covered at the back.
Later in the day, the team tried another version of the guards with spoke-like sides.
Ferrari’s reserve driver Oliver Bearman followed Leclerc in a 2024 car to check visibility.
The FIA organized the test, but it won’t count as a filming day for Ferrari.
Last year, the FIA tested the first version of the spray guards at a wet Silverstone to improve visibility for cars behind in rainy conditions. The system included partial wheel covers on both the front and rear tires.
Mercedes’ reserve driver Mick Schumacher conducted the first test, with McLaren’s Oscar Piastri running behind as a control.
However, the first test didn’t make much difference to the spray produced by the cars.
“The spray guards covered too little of the wheel,” said Nikolas Tombazis, the FIA’s single-seater director.
As a result, the FIA promised a more aggressive solution, which Ferrari tested at Fiorano.
Tombazis explained the complexity of finding a successful solution. He said they didn’t want to lose too much performance or disrupt the aerodynamics of the cars.
On Friday, Ferrari will use a filming day to test the new aero package for the Emilia Romagna Grand Prix next week.
