Dirty air impact reduced by five times in the F1 2021 concept


The move from F1 to more powerful vehicles in 2017 resulted in reduced overruns and wheel-to-wheel behavior, while riders struggled to keep up with other cars because of increased loss of performance. during the turbulent race.

Improving the quality of the race has been a primary goal for the next round of championship rules. While F1 has already introduced many changes to increase the number of overruns in 2019, the series leaders have promised a much more substantial impact of the 2021 rules.

When launching the first F1 car concepts in 2021 in Singapore last year, Brawn said that F1 had concepts that would allow cars to retain up to 80% of their performance in the car. But before this year's campaign, he had proposed a larger estimate. again.

"There is already a huge difference," he said. "With the current car, with two car lengths late, you lose 50% of the performance.

"The car we have [in the works] now you lose 10% of the performance. It is therefore a huge improvement over the current situation. "

It is difficult to accurately measure the true impact of stale air. Nikolas Tombazis, head of the FIA ​​single-seater, estimated that 2018 cars lost only "about 30%" of their workforce while they were following another car "between 15 and 20 meters" opposed to Brawn's suggestion. 50% at two car lengths.

The Tombazis had targeted a one-third reduction in performance loss with this year's rules.

An overall reduction in support has often been suggested as a solution to the current overtaking problems of F1, but Brawn thinks that this would not suit F1 conceptually.

"I heard that we had to get rid of the wings and supports and that we could only rely on the mechanical grip so that the cars could cope," Brawn said.

"The problem is they will be slow. And the speed of the Formula 1 car is breathtaking.

"We do not want to lose the speed of the Formula 1 car. We want it to be the fastest racing car on the planet, the most impressive on the planet – and you can only do it by exploiting aerodynamic performance.

"So, I do not think we can have a simplistic vision and just get rid of all the support and think that it will solve the problem."

"What we need is that the supports are delivered in such a way that the cars can cope."

"Exceedances can sometimes be used as a measure of success, but in reality, tight races and the ability of cars to run behind each other and run side by side to get close and attack are what excites everyone. .

"Although this did not ultimately lead to an overtaking – but [as long as] they fight. "
