It would be illegal for Toyota to do CFD analysis for HAAS.
Can you point to the regulations that would make it illegal? As a technical partner, what are they allowed to do?
Komatsu recently said while they will continue to use Ferrari's WT because of it's recently installed rubberized floor, he also said he wouldn't say "never" in terms of using Toyota's one day (if they upgrade it and such). He also mentioned logistics, naturally. In the same article it was noted that Andretti is using Toyota's WT. Andretti isn't a confirmed entry for 2026 and what WT/CFD limitations are they subject to? None, is what I thought.
Similarly, as AMR's power unit provider and technical partner, what is Honda not allowed to do? My understanding is that Honda also factors in aerodynamics and vibration amongst other factors in their test rigs. To what extent are their own CFD resources allowed? I've wondered the same about Dallara and what are they limited to do for Haas. It goes without saying that AMRs WT should be sufficient but CFD is a different area in itself. While the CFD time is limited, is it stipulated that it has to all happen under the same roof?
What I mean by Illegal is that whatever Toyota does, would have to have a cost associated to it and it would be applied against the CAP. Computational Fluid Dynamics (CFD) time is controlled in Formula 1 and CFD can only be done at 1 designated site.
From ChatGPT:
These restrictions include limitations on the computational power and memory that can be used for CFD simulations.
CFD limitations:
The FIA has set limits on the main memory capacity and compute power that can be used for CFD simulations, with a maximum compute power of 12.288 GFlops.
Restrictions on CFD usage:
The FIA has also introduced restrictions on the number of CFD simulations that can be run, as well as the amount of data that can be processed, to prevent teams from using excessive computational resources.
