With the present vehicles already freely giving as a lot as 50% of the aero efficiency gained because of the 2022 guidelines overhaul, F1 is additional modifications for 2025.
“It is beginning to grow to be a bit like 2021 or 2020 the place it’s tough to comply with,” stated Carlos Sainz following final weekend’s Italian Grand Prix.
Certainly drivers have been expressing their issues over the issue in following rivals since late final yr, simply months after the much-anticipated overhaul, and whereas it’s too late to implement modifications for 2024 the FIA is now trying to 2025.
“If we take the 2021 F1 vehicles, based mostly on being two lengths from the automotive in entrance, they have been dropping greater than 50% of the aero load,” Nikolas Tombazis, the FIA’s single-seater director, tells Motorsport.it.
“With the 2022 single-seaters, there was solely a 20% discount in load. However now we’re at about 35%. Certainly there was a worsening and, on this level, Carlos is true. We’ve got recognized what we must always act on.
“We’re learning options for 2025,” he confirms. “We’ve got recognized some components of the vehicles to behave on, such because the endplate of the entrance wing, the aspect of the ground and the fins contained in the wheels. We may lay down considerably extra restrictive guidelines in these areas.
“It’s clear we now not have the benefit of 2022,” he admits, “and due to this fact we all know that there’s work to be completed.”
Of specific concern to the game’s governing physique is ‘outwash’, the place the airflow is directed away from the automotive and tyre, in some instances courtesy of flexing wings and the like. This, in flip, impacts the automotive following which loses downforce.
“We’ve got the proper to behave on versatile bodywork after we see one thing that doesn’t persuade us as a result of the regulation says that components needs to be rigidly secured and motionless,” says Tombazis.
“In actuality, we all know that this isn’t strictly potential, so there’s a proper to use widespread sense. The rules don’t enable us to behave on issues we don’t like on the vehicles.
“There are a number of elements within the interpretation of the aerodynamic rules that we don’t like in the meanwhile, however to vary one thing we would want to undergo the procedures to attain a broad consensus.
“Typically we have now tried to vary issues, however we have now not at all times achieved the consequence we wished. I imagine that 90% of the rules are in step with what we wished and there’s 10% that, with hindsight, we might have completed another way.”
