The underlying physics will not be the same, the have already been quite clear on this, with a locked core temp it will be impossible to let the tyres get to cold or hot (outside of temporary flash heating), that is categorically not just like PC2 or PC1. Wet tracks cool slicks rapidly (carcass and core) and make a huge difference to how they behave, that is gone.
You missed a question!
,
It also totally removes the element of should I stay on slicks and risk it or pit for wets and hope the lost time can be pulled back.
No amount of spin makes that just like PC2 or PC1, and while it may be something you and others are 100% fine with, attempting to sell it as just the same is utterly inaccurate.
I disagree. But as we've already had a very short discussion on this and why we disagree theres no point continuing that argument.
Of course you still have access to your setups, though—aero, brake tuning, weight distribution, ride heights, alignment, springs, dampers, gearing and differential as well as tyre pressures are all there
Project CARS 3, you’ve got multiple layers related to the heat model. Flash, Layer, Tread, and so on. Flash is the elements which touch and grip the track surface, Layer is an intermediate layer for diffusing heat energy, and Tread is the core bulk of tread rubber. All the heating dynamics in Flash and Layer still happen, we just lock temperature from Tread down through the rest of the model. I suppose a simpler way to put it is that the rubber layers influence tyre grip naturally at these time levels:
Flash Layer – What are you doing this instant?
Surface Layer – What were you doing in the last 5s?
Bulk Tread – What were you doing in the last 5m?
The biggest benefit comes from those three rubber layers of varying thickness and how they separate transient behaviour of the rubber from longer term heat effects.
The first, Flash layer, models the individual Setae contact points and is only 30 microns thick. This is where we do all the work-energy heating and you see huge temperature swings here—the heating of Flash layer is a primary tool for shaping our slip curves. We then have a surface layer between 0.5-1.0mm thick for the heat to diffuse though; this reacts more slowly but still pretty quickly.
just to highlight for those who might have missed it and are acting like all tyre heat has been abandoned. @Scaff I get your point obviously around how you feel that's gonna be with locked in core temps, I disagree personally, neither of us will know until we play the game. Sure the build up to optimal core temperature will be different, it's not like the physics have been completely changed by simply locking in an optimal temperature for 1 or the 3 layers of tyre heating. In F1 2019/2020 you can have either surface and carcass simulation or just surface, the phyics don't fundamentally change when you switch between the 2. It feels identical, it alters ever so slightly the build up to the core temperature when both are simulated.
