Every season at least one team falls foul of accusations of illegal flexing parts. This season it's Ferrari's car.
At the race in Bahrain one of the commentators said that he saw something unusual going on with Ferrari's car, and that teams should look into it.. Within 24 hours Red Bull along with a couple of other teams were shouting foul.
It appears that some slow motion replays filmed at Bahrain and at the recent two day test in Bahrain, that Ferrari's floor us flexing in a limited area towards the track at high speeds, and that Ferrari's rear wing and defuser are also flexingdown towards the track.
There small area that appears to be flexing on Ferrari's floor, is located just below the Shell and UPS logos on both side pods. The tech drawings I have seen concerning this area of the show a small triangular Winglet, created by a slit cut into the floor. After viewing a number of videos, I must admit that this small area does seem to flex, but in my opinion the not enough to warrant further investigation.
However the rear wing issue is another issue.. As the car approaches about 3/4 of the Ferrari's top speed, it is clearly flexing down towards the race track.
Ferrari aren't new to this issue, a number of times they have faced allegations such as this, and over the years so have Red Bull, Honda amongst several others.
Yes Ferrari's Rear Wing and floor have passed inspection, but me there are some problems with the tests themselves!!!
Let's tackle the floor first, flex tests are performed towards the front of the floor and the floor area directly in front of the rear wheels. Ferrari's. The area where flexing allegations are rising from are not tested, despite there being no rule in the FIA's rules that say this area can't be tested.
The rear wing rules are clear though, the rear wing isn't allowed to flex. And in my opinion the FIA should act on this immediately.
Flexing rear wings can aid in increasing speed without decreasing down force to a level which effects handling especially in high speed corners, and help create a small amount of extra speed on the straights.
These problems could be solved if the FIA were to mount sensors on/in the areas of concerned, and then tested these cars at high speed.
Ferrari are also the only team with two vertical pylons that attach to the rear wing, which some teams have suggested aid in the movement of the rear wing. Each pylon disrupts airflow and having two doubles the negative effect on the rear wing.
I know that all cars have to pass a lot of tests inorder to race, but the area's where flexing a
