Dirty air impact reduced by five times in F1 2021 concept

F1's switch to higher cars in 2017 triggered a reduction in overrun and wheel-to-wheel action, as drivers struggled to run close behind other cars due to increased performance loss while driving in the car's forward-looking wake. Raising fitness quality has been a main goal for the championship's next cycle of regulation and while F1 has already introduced a number of changes aimed at increasing the upper hand for 2019, the series managers have promised a significantly greater impact from the 2021 rules. When F1's first 2021 car concept was launched in Singapore last year, Brawn said that F1 had designs that would allow cars to hold as much as 80 percent of their performance in dirty air &#821 1; but before this year's campaign he has offered an estimate it was yet major. "There is a huge difference already," he said. "With the current car, two car lengths behind, you lose 50 percent of performance. " The car we have [in the works] now loses 10 percent of performance.

F1’s switch to higher cars in 2017 triggered a reduction in overrun and wheel-to-wheel action, as drivers struggled to run close behind other cars due to increased performance loss while driving in the car’s forward-looking wake.

Raising fitness quality has been a main goal for the championship’s next cycle of regulation and while F1 has already introduced a number of changes aimed at increasing the upper hand for 2019, the series managers have promised a significantly greater impact from the 2021 rules.

When F1’s first 2021 car concept was launched in Singapore last year, Brawn said that F1 had designs that would allow cars to hold as much as 80 percent of their performance in dirty air &#821

1; but before this year’s campaign he has offered an estimate it was yet major.

“There is a huge difference already,” he said. “With the current car, two car lengths behind, you lose 50 percent of performance.

” The car we have [in the works] now loses 10 percent of performance. So it’s a big improvement over where we are today. “

The real effect of dirty air is difficult to measure precisely, with the FIA’s head of single seats. Nikolas Tombazis has estimated that 2018 cars just” lost about 30 percent “of their downforce while following another car” 15 to 20 meters back “- in contrast to Brawn’s 50 percent suggestion in two car lengths.

Tombazis had targeted a third reduction in performance losses with this year’s rules.

An overall reduction of downforce has often been made as a solution to F1’s current takeover woes, but Brawn believes that this would not fit F1 on a conceptual level.

“I have heard it commented that we would get rid of the wings and downforce and just rely on mechanical grip and then the cars can compete each other, Brawn.

“The problem with that is that they will be slow. And the speed of the Formula 1 car is what takes the breath.

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

“So I don’t think we can take a simplified view and just get rid of all downforce and think it will solve it.

” What we need is that we can deliver in a way that cars can competing each other.

“Takeover can sometimes be used as a measure of success, but in fact close racing and the ability of the cars to run behind each other and drive side by side and get close and attack are the things that everyone gets excited about.

” if it ultimately did not culminate in a jump that was achieved – but [as long as] they fight each other. “
