No updates listed for AMR, is the lighter gearbox arrived yet..
I do not think Aston Martin have to declare lighter parts if its shape is still the same.
Sorry not picking on you....
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."
