What does Ferrari have in the floor?
As soon as Ferrari is victorious, the competition looks more closely. She wants to see that the underbody, the rear wing and the diffuser bend during the ride. There are no more than indications.

As soon as Ferrari is again a team that can win, the opponents look twice exactly. The new Ferrari SF70H is an all-rounder. It is fast in heat and cold, on hard and soft tires, in slow and fast turns. And the question is, how is that possible?
Mercedes-Teamchef Toto Wolff was impressed by the road situation of the Ferrari in the fast corners 7 and 8 of the Shanghai International Circuit: "The drivers steer once, the car is like a board and drives without twitching through the curve." Daniel Ricciardo "The Ferrari often do not go to the edge of the track at the corner exit. This shows that they still have reserves. "
Suspicious carbon strip in the Ferrari underbody
The first rumors appeared in the test drives. As a Ferrari on the under-floor integrated a 2 meter long carbon strip with temperature sensors, the competition was noisy. After 6 days, the carbon texture was again uniform. To this day one does not know what was concealed behind it.
The competition teams still did diligently photos, also on the course. According to her testimony, this shows how the undersurface has bent downwards at the sides and thus forms a kind of tunnel to the road. This could help to shield the flow under the car beautifully to the outside.
The photos showed even more. Supposedly with top speed also the tail wing with diffusor bowed to the rear. In this way one could increase the top speed without having to abandon downforce in the curves.
One-piece Ferrari floor divided into three segments
In Shanghai, some of the teams saw their suspicions confirmed: An engineer told us: "There were slow-motion recordings from Raikkonen in the training, with the ground actually bent down on the sides."
However, the effect does not exceed the full width. The FIA measures the stiffness of the ground at two points. Front on the skid and on the edges just before the rear wheels. These tests consist of the Ferrari. However, the bending was observed only in a range up to about 20 centimeters in front of the rear wheels.
It looks as if the Ferrari-Unterboden consists of several parts.
The underfloor of the Ferrari SF70H still has a special feature. Although it consists of a single piece, it looks as if it were divided into three separate segments from the bird's perspective.
The mean is significantly higher in comparison to the other two. There, the sensors are also accommodated, with which the temperature of the rear tires is measured. You can see the heel to the other floor parts at a fold in the side view (see gallery).
Now everyone is puzzling what is hidden beneath it. The imagination is of course no limits. Does Ferrari in this area be about ballast? Are the segments made of different stiff carbon structures? Are installed inside the bulge lines? Espionage photos of competition teams from the Ferrari garage have not yet been able to show anything suspicious. Apparently, at least "foreign bodies" are not integrated into the bulge of the subsoil.
Why does the Ferrari rear wing have two stilts?
Ferrari's opponents also claim that the rear wing and the diffuser fold away at high speed. This would reduce air resistance and provide better top speed. In the race, Mercedes and Ferrari were only 0.9 km / h on the long straights.
Also for this theory, the technicians of the competition have indices. You wonder why the Ferrari as the only car has two rear wing props. Aerodynamically, that makes no sense. "Each prop disturbs the flow. If you have two of them, you are dealing with this error twice, "it says.
The engineers see the reason for the two pillars to tilt the wing specifically. It is not the first accusation of this kind. Earlier, different teams were suspected of winning top speed with this trick.
As far as the underfloor is concerned, the suspicions have already spread to the FIA inspectors. There you are relatively quiet at the moment. It is not chiselled in stone that the inspectors only test the stiffness of the floor at the two predetermined locations. The rules allow the FIA to change the inspection stations at any time.
