While I'm normally first to criticise Pirelli they were expecting to shift to 18" next year so investing heavily for another year of 13" seems daft especially as teams are being forced to keep their chassis' to save costs. This will lose around the equivalent downforce that they'd normally gain by next year, so for tyre loads the status quo is maintained.
I agree that developing new tires would be stupid, but I would still criticise Pirelli for making a tire that can't handle the added downforce of completely stable regulations, they already have to regulate camber and tire pressure for their tires to hold up.jjn9128 wrote: ↑28 May 2020, 11:23While I'm normally first to criticise Pirelli they were expecting to shift to 18" next year so investing heavily for another year of 13" seems daft especially as teams are being forced to keep their chassis' to save costs.

The losses are expected to be greatest in high speed corners according to FIA.
I presume it will limit the way teams seal the floor, so yes... but, we don't know how much a team like RedBull (who's cars generally have the most rake and I think started this whole thing) rely on the slots on the edge of the floor.JordanMugen wrote: ↑28 May 2020, 18:13The losses are expected to be greatest in high speed corners according to FIA.
Will this trimmed floor create unintentional high speed rear-end stability issues for nearly everbody (similar to 2019 Renault & 2018 McLaren)? It would be most amusing if it did.
Can we expected the trimmed floor to disproportionately disadvantage high-rake teams, and enhance Mercedes advantage with their more consistent low-rake car?
You really think it'll be this miniscule?? I think the taper will spill alot more of high pressure air from the top of the floor into the underfloor.

No change in downforce as changes to the cars will negate the small loss. There will be more air smacking the rear tire, instead of it being channeled underneath and to the side. It does offer a clearer shot of guiding air over the diffuser.
Luckily teams are stuck with this year's rear end for next year, so whoever has the best rear end this year will keep the advantage next year.
The outwash is not as much about drag as it is about pulling the tire squirt outboard of the rear tires. When this is removed much of the tire squirt will go on the inside, into the diffuser making it less efficientgodlameroso wrote: ↑06 Jun 2020, 15:16The current floor actually creates a down and outwash in front of the rear tire. It attempts to simulate outwash at the front. By tapering the floor, you lose that so the turbulence of the tire(which is speed dependent) is greater creating more drag. Remember that most cars are set up to squat at high speeds.
Teams will have to find a new cross over point and will have to tune the rake at different speeds to get the most of the new style floor. However once they do that, they'll find it doesn't decrease downforce too much.
It may shake things up in the first 1/4th of the season while teams get on top of it.
