No, it is OK. I appreciate learning about the minute details in the rules. So a lighter gearbox under the guise of "reliability" reasons would have to be crash tested for structural integrity because it anchors the chassis?diffuser wrote: ↑11 Sep 2026, 15:00Sorry not picking on you....TyreSlip wrote: ↑11 Sep 2026, 12:23I do not think Aston Martin have to declare lighter parts if its shape is still the same.collindsilva wrote: ↑11 Sep 2026, 12:14No updates listed for AMR, is the lighter gearbox arrived yet..
You can't just update the gearbox to make it lighter, tge rules prevent that. It can only be updated for reliability. Even then it's complicated.
Interesting article https://f1chronicle.com/f1-gearbox-rule ... mandatory.
"This dual function means that the gearbox design cannot be optimized purely for transmission performance without regard to its structural role, and the structural requirements it must meet are among the factors that determine how much scope the team has to minimize its mass. A lighter gearbox casing that meets the transmission requirements but not the structural requirements is not compliant, since both sets of requirements are mandatory. The structural tests that verify the gearbox casing’s integrity as a chassis member are part of the homologation process, and changes to the casing that affect its structural performance require the same retesting that would be required for equivalent changes to any other certified structural component."
