F1-75 and SF-23: performance 'saturation'
“We must oppose these innovations”. Adrian Newey stated that within Red Bull there were technicians who argued that it was important to fight against the new 'anti-porpoising' rules established by the 2023 regulations regarding the height of the car floor and the dimensions of the floor in the wheel area rear. Newey then dissuaded these technicians by hypothesizing that the changes to the regulations would have had a greater impact on the aerodynamic concept on which Ferrari had designed the F1-75 than on the basis of the Red Bull RB18.
The Ferrari F1-75 developed a lot of aerodynamic load in fast corners, more than the Red Bull developed, but in 2023 the SF-23, also due to these changes to the regulations, lost this prerogative, regaining its performance shine at the end of the season at end of a long update process which allowed the Scuderia di Maranello to collect important information for 95% redesign of the SF-24.
Even without the regulatory changes introduced in 2023, Ferrari would still have changed the aerodynamic concept because that of the F1-75 had reached performance 'saturation' as underlined by the chassis technical director Enrico Cardile at the press conference: “I don't think the regulatory change has influenced what we have done – Cardile's words – the 2022 concept was good, but, in terms of how much we could progress, we would have made less progress compared to the new concept. The choice is linked to the peak performance that can be achieved with a given concept. The 2022 car was stable and had a lot of load, but when we started to increase it we began to believe that a new concept would allow us to go even further.”
