Umbrella organization FIA in Liberty Medium put a lot of hope on new rules for 2021. Racers are supposed to be more manageable and thus make racing more interesting. But how realistic the set goals are? The FIA now had to admit that vacuum values from studies they have done, probably they will not achieve.

As part of the race US GP the FIA and Liberty Media introduced the new ones technical, sporting and, for the first time, financial rules of the royal class of motorsport. It plays the biggest role in technique aerodynamics. Thanks to the so-called "Ground effect”And chassis simplification, si FIA promises to increase the vacuum for racers driving behind a competitor. It should be simplified front wings, which would not react so sensitively to air turbulence. So-called bargeboards pilgrimage to history. This is supposed to facilitate duels and overtaking.
Judging by the words ombudsmen, in research and development of a new policy for leto 2021 found that the car has at tracking another car with the distance between the lengths of one car now available around 55 percent of its own vacuum. The new policy is expected to increase this value to 86 percent. At a distance of length three race cars the vacuum level is expected to improve from 68 to 94 percent and at a distance of seven race car lengths from 79 to 98 percent. However, these values are only first basis, based on the current estimated values given to the umbrella organization FIA mediated by one of the teams. This prediction for 2021 however, it also predicts how teams will interpret these new rules.

That's why at the moment difficult to assess, whether this significant improvement will really also put into practice. FIA Sports Chief of Formulas, Nicholas Tombazis, is a colleague from Motorsport-Total.com admitted that it was previously unbelievable that the desired percentages would actually be realized in reality as well. However, he also stressed that even if it will less progress, this is still an acquisition. “Of course, when developing their race cars, the teams will not worry that the conditions for the race cars driving behind them will deteriorate. That is not their goal. They want a race car that will be as fast as possible." Tombazis however, it acknowledges that it expects less high vacuum values than those shown in their graph. “I think the curve will climb less than planned. However, I am speculating on this, just like everyone else. They may lose a third of the advantage, but it’s a big bite nonetheless."

He also remarks that they will the best race cars on the track, Mercedes Benz ali Red Bull, more sensitive and therefore lose more vacuum if they follow a car than the figures given by the survey FIA. “The net effect will be a big step forward. Maybe not as big as in the graphics.“Teams because new policy they will no longer be able to control the effect on the front wheels. With the return Ground Effect will development focus moved to the bottom of the car. “We have a good overview of which areas of the car are particularly sensitive to air vortices. And there are some areas where we can find solutions to improve these turbulences."
Tombazis give an example: "We found that if a race car finds more performance on the diffuser, the airflow characteristics improve significantly."It simply came to our notice then FIA also more relaxed as far as is concerned freedoms of engineers in this area. “On the other hand, there is a front wing end plate that can interact with the wheels, an area where these benefits can be quickly wasted. As a result, we have limited this area even more."
