Is dirty air a thing? Because if it isn't, the placebo value is over 9000!

    Okay, so Im pretty sure I know dirty air is a thing and has been around for a while... Even with a few threads on this forum from July 2015 and prior, but I just wanted to give some credit here to Kunos for having enough depth in the physics to make these new F1 cars a truly exciting and exhilarating experience online.

    Been messing about with the F138 a fair bit the past few days at Spa, and have been noticing when you are barreling down the Kimmel straight and are about to enter the braking point for Les Combes... If you are tailing another car with DRS in full effect, but arent quite close enough to cleanly pass, so you duck in behind them... it feels like the downforce has just been sucked away from your wings and you will brake long if you dont plan ahead for this. Quite neat to see the effects of losing some downforce, and blowing your braking point :D

    Even better though, was a race I was just part of. First few laps of a race and someone is hot on my tail through Campus (still at Spa), so Im trying to hit some good lines through Stavelot to get some good exit speed on the long straight before the final chicane. Well, immediately after the first exit of Stavelot, the guy tailing me seemingly lost all his downforce and spun just enough to drop back a few seconds. Fast forward 2 laps and he is right on my tail again in the same section, and what do ya know... the same thing happens!

    After the race he made a comment about how crazy dirty air can be and how you really need to be careful.

    Adds quite a nice touch to the overall racing experience in my opinion and a nice element of strategy to really plan the optimal pass if you and your opponent are near equal in pace, or one person is slightly faster. :)

    Anyways, thanks to Kunos for these awesome F1 cars, and all the other improvements to the game since v1.0. It's come a long way, and the future seems to hold just as much ahead for us all. :)

    Cheers

    Strange, I noticed something whilst drafting in the new Ferrari 488 GT3 when i was tailing the AI at very high speed the car felt so unstable in the turbulent air, I too wondered if I was imagining it. felt amazing btw.

    It is there for a long time... I would say pretty standard thing in sims.. But to my question if dirty air will influence brake and engine temps the answer was no...i guess no big deal since we don't have engine temp yet and lose of power when temp is too high :)..

    This is very cool. I knew that you could draft in slipstreams in AC, but didn't know it would mess with your downforce and stability etc. :cool:

    I could be wrong, but like the original poster Said it's a very strong placebo effect.

    Guys what are you on about?
    Slipstream in terms of reduced drag, AND dirty air in terms of reduced downforce has been on AC since... I can't even remember.

    Each car in front of you creates a cone of "dirty air" that gradually reduces your drag and downforce. Obviously the effect is not fixed but depends on the cars involved. Following a car with a street car, you'll feel the effect less. With a GT3 a bit more, with a Ferrari SF15-T much much more.

    I think it may be more profound since 1.7 or maybe just in the 488. I haven't driven the formula cars in a race yet.

    nope the v1.7 definitely hasn't changed anything regarding this feature, but the 488 GT3 car is one of the GT3 cars with the most downforce, so it might be suffering more... not by much but it might be more noticeable to you.

    iirc Stefano said in one of his streams that the new F1 cars suffer from dirty air.
    Pretty sure that effect was (almost) not present with the Exos S1.

    So it's unlikely that it's only a placebo.

    Probably I ran imola and the nature of turn 1 when your almost redlining 6th gear I moved out to the right slightly to spot my braking point and it just felt like it could 'let go'. Its become such a great experience and I have to say I love driving that ferrari more than any other gt3, perhaps that's the new tyre model. Over the moon with the latest Dlc and update.

    On the F1's it's quite prominent. I especially noticed it in Eau Rouge on Spa... best to keep a bit of distance to the front guy there.

    Well yeah. Mainly my point was that I didn't feel anything like that on the Exos, so maybe the aero is different on that one such that you can't really feel it that much?

    Could also be that I didn't trust the people in front of me enough to get close enough, who knows? :D
