Ground Effect Anomaly Fixed: Ferrari’s New Dawn

27/09/2024

Ferrari claims to have resolved the ground effect anomaly, potentially ending the bouncing issues for Leclerc and Sainz.

Ferrari believes it has finally resolved its bouncing issues, which reappeared with a floor update. As engineer Jock Clear explains, they detected an “anomaly” causing a significant lack of correlation.

“You’re never fully confident, but I think it’s a good representation of the ebb and flow of everyone’s evolution,” Clear said. “But you’re probably asking the same questions. After Spain, we didn’t feel we had lost our way, but there was an anomaly between what was happening in the wind tunnel and what we were seeing on the track, and we needed to address that.”

“It’s simply the process; when you see an anomaly, you have to deal with it, try to understand it, then get back on track. And I think what you’ve seen since then is that we’ve understood it, we’re back on the right track.”

“We just need to keep our eyes wide open for the next anomaly, because there will be another one since that’s the process right now. So it’s not about saying sometimes development works, sometimes it doesn’t.”

“The development process is precisely about testing something new each week. We are confident that our process is working and that we have the situation under control. We just have to wait for the next banana skin.”

No “100% fidelity” between the factory and the track.

Clear explains that the wind tunnel can’t simulate everything, especially phenomena occurring at very high speeds when the car is very close to the ground, making the ground effect much more significant.

“I think since we brought back these ground effect cars, they have posed challenges that have… simply put, when the car is far from the ground and the ground does not generate huge amounts of downforce depending on its proximity to the ground, the wind tunnel can be quite accurate.”

“But as soon as it comes to what happens over a curb, what happens when it bounces, the wind tunnel can’t do that. We can make the car bounce up and down. But of course, then the data gets messy. But whatever the data looks like on the track, it’s the driver who has to drive it.”

“There is a certain level of correlation between the wind tunnel and the track, and it’s hard to achieve 100% fidelity. You will always have these anomalies, and with the ground effect, the anomalies are larger because the proximity to the ground becomes that much more powerful as soon as the ground effect comes into play.”

“When the ground effect is null, you lose all your downforce, and when it goes up to five millimeters, you gain a significant amount of downforce, and you find yourself in this peak ground zone. And everyone is constantly facing this issue.”
