That calm air as you put it has momentum and is moving in the same direction as the vehicles. Good in a straight line for catching someone, bad in the corners when the car cant work the air as hard and thus makes less downforce. The cars are designed in simulations by themselves, optimized to run in clean, still air. The air getting dragged with the car ahead will have a lower dV relative to the following car, difference in velocity over/under a wing being what generates lift due to the pressure differential it causes.strad wrote: ↑Tue Jan 29, 2019 8:04 pmThis thread has helped me understand a lot but there is still something I don't understand.
Yes the following car finds a lot of disturbed air as it comes up behind another. But why can't it push thru that disturbed air and enter a calm space close behind the leading car.
Like drafting in other series.
Turbulence is an issue, but even the non turbulent air behind a leading car causes issues.
