Aerodynamic Drag / Speed Test (2.08)

[sumbrownkid]

In the run up to the first chicane down Mulsanne, my GT-One at 750 HP and tranny set to 249 mph managed to reach 242 MPH at min downforce. At max, it reached 231 MPH.

For curiosity's sake, I wanted to see if the ride height made any difference to speed, and to my surprise it indeed does. At minimum ride height for the GT-One, the car claws 3-5 MPH more compared to stock height. That said, the over twitchiness and rough ride at minimum ride height outweigh the gains in speed.

That ride height still makes the car faster, but adding Aero on the rear slows the car down.

Something I found earlier with the LM prototypes, if you add 55 rear wing (where 50 is the lowest setting) you can get a higher speed than at the lowest setting. The still-comical 200kg ballast on the nose also gives higher top speeds than without.
I've tested a few of the more powerful LMP's and there's quite a few now running over 300mph without draft over the standing 10km test

I suppose then PD did what they said they would and nothing else. They increased the drag changes associated with downforce (it's a bit telling that stock values didn't change which seems to indicate that they are hard coded as defaults and makes the "wing number" even harder to understand). All the glitches and exploits from before still apply.

Though in this case, I guess completely redesigning the aerodynamics code might have been out of the question. I guess that's something for GT6 (hopefully).

That all sounds correct to me. Just a simple tweak of the numbers. As far as GT6 is concerned, I think we're all hoping. But even small changes now should mean that the series is headed in the right direction. Were it ends up, we'll have to wait to see.

Max aero is still the fastest way around any track though.. 👎

But it's ofc better than before which is a good thing.
