"From around 2024, images of the floor bottom will not be available extremely.
In the first place, there are few crashes, and it seems that the introduction of a cover that hides the floor, which is an important secret, and the decrease in the number of photographers.
In the meantime, let's take a look at the floor of the Ferrari SF-25 that was hoisted by the Monaco crane.
A line is drawn in the part of the tunnel where the angle changes.
(1) Kick point near the entrance
(2) Kick point immediately after the edge diffuser behind the fence
(3) Kick point where the rear diffuser begins in earnest
(2) and (3) seem to be at the same height, but I feel that (2) is closer to the road surface.
You can see that (2) has a complicated serving shape. It is probably being redesigned in an update.
Problems at the start of Ferrari's season
-High-speed bottoming
When driving at the expected vehicle height, the bottoming did not stop, and the vehicle height had to be raised. (Negative pressure increased too much)
The time slows down because the expected negative pressure is not obtained, and although it has been updated, it is far from a fundamental solution.
Floor of SF24
Compared to the floor of the SF-24, you can see that the 25 is an updated version of this.
Ferrari's floor tunnel is based on the idea of making the maximum negative pressure generation point at the center of the car, which has not changed since 2022.
McLaren 2024 MCL38 floor
This is the floor of Miami when McLaren is faster in 2024.
This year, the basic concept should remain the same.
While the Ferrari is positioned at the front of the floor and immediately approaches the road, the McLaren has a gentle slope towards the rear kick point.
The inside of the tunnel is an inner groove, which contrasts with the Ferrari with the outer groove.
This concept has been brushed up from the Red Bull RB18 and has now been updated to a design that surpasses the original and boasts unbeatable strength.
Summary
In the first place, why is it better to have a kick point (a place where the angle changes as it is closer to the road surface) at the back?
This is because it is easy to adjust the negative pressure of the kick point by adjusting the rear vehicle height.
It is easy to take into account the ride height that decreases due to the downforce of the rear wing, so there is an advantage in terms of settings.
In the case of Ferrari, there is a maximum negative pressure generation point in the center of the car, which must be adjusted according to the front and rear ride heights, which is very difficult to set up.
It can be assumed that the reason why Hamilton cannot run fast is because he is suffering from this downforce balance."
