(Motorsport-Complete.com) – The teams have already worked extensively in the second half of the season 1000 Parts for the Formula 1 season 2021 tested in public. The first free practice at the Abu Dhabi Grand Prix 1000 was now the last big probability. Ferrari was particularly noticed.

The Italians were waiting with a monumental scaffolding at the rear of the SF 1000 on. The dimensions of this monster give united states of america an inkling of the complex consequences of the changes in the regulations for the season 2021 really have.
The curved shapes of the scaffolding serve to minimize its effect on the airflow. It should only measure with its sensors and not intervene in the current.
The placement of the probes itself could herald a new vogue: Unlike in the past, than the sensors on the rather checkered scaffolding were arranged in a strict grid, Ferrari placed the probes at various points on the curved structure. They are now oriented more towards the direction of the air flow and should therefore provide more precise data.

Ferrari apparently wants to understand the structures of the air flow behind the vehicle more precisely. The “wake” that the diffuser leaves in the air spreads like a mushroom. Ferrari wants to produce exactly this when evaluating the new parts for 2021 get to the bottom.
These new parts are mainly a new underbody, which is replaced by a previously tested 2021 variant differs. Like the Formula 1 regulations 2021 a diagonal piece is cut out here as well.
In the middle of this cutout there are now three curved fins. The Clothier are already in the process of preparing the flow of air to meet the rear tire in the best possible way.
At the same time, the original “dog-ear” at the end of the underbody has disappeared. It was replaced by a number of other fins, which were supposed to take over the micromanagement of the air flow even more finely.
After Renault in Bahrain various 2021 test parts, a new sub-floor was also used in Abu Dhabi. However, the French were still one stage behind Ferrari. In front of the rear tire there was a “dog-ear” on the top of the underbody.

After the new rules, plenty of space take away, this area will be the scene of great development battles in the Formula 1 season 2021.
Every employee will try to optimize the airflow to the rear tire. The aim is to limit the negative effects that the incisions have on the flow to the diffuser.
Haas and the critical zone
Haas also jumped on the 2021 he train and equipped the VF – 16 for the first time with parts for the coming season. The US-Employees did not even bother with a “bare” baseline sub-floor, as has often been seen with its rivals.
Instead, they started with a more complex solution. When trying to improve performance, Haas already had in the Formula 1 season 2020 many resources have been put into the area in front of the rear tire. A whole series of holes, cuts, flaps and wind deflectors should manipulate the air flow so that it harmonizes perfectly with the rear tire.
In order to The Employees tried to compensate for the turbulence caused by the tire and the effects on the air flow to the diffuser. Especially when cornering, the deformation of the tire can cause unwanted turbulence and cost a lot of downforce.
When 2021 er subfloor, Haas uses its knowledge in this area even under the new regulations. At the end of the sub-floor there is the well-known “dog-ear”. Much more interesting, however, is a large horizontal flap above the sub-floor, which is attached to a standing plank.
Crimson Bull already started in Portugal to deal with the effects of the 2021 regulations. In Abu Dhabi they started looking for further answers.

The first outgrowths also appeared on the Crimson Bull sub-floor in the critical zone. In this case it is a curved fin just in front of the rear tire. Compared to the other teams, it is a good bit away from the end of the underbody.
Also on the rear wing, which is already in Bahrain was tested, work continued. The wing on only one stilt returned. This time, however, it was used all weekend – and with success.
Mercedes has no aerodynamic components for the Formula 1 season 2021 publicly tested. But that does not mean that the first free practice session in Abu Dhabi cannot be used to prepare for the season 2021.
The W 11 drove several times in free practice without the double-axle steering DAS. The drivers should be prepared for a life without the possibility of being able to adjust the track of the front tires while driving.
The machine has proven to be very useful in situations where drivers needed to get temperature in the tires. This helped them especially during the SC and VSC phases, but also at the start of the race.
In the FT1 at the Abu Dhabi Grand Prix 2020 the Mercedes from Valtteri Bottas was equipped without DAS. Lewis Hamilton, on the other hand, was given the opportunity after his compulsory break to familiarize himself again with the machine that was used one last time in the race.
