The FIA has issued an invitation to tender for a common F1 gearbox cassette for the 2021-24 seasons.
The governing body wants all competitors to share common internals but have their own "team specific" gearbox casings on which the suspension is hung.
This was being discussed in the 2021 engine regs thread but I think it's big enough of a change to merit its own thread?
One of those things where the purist racer in us dislikes it, but maybe makes logical sense? Liberty (Brawn) do have been saying since the beginning that they wanted to identify some areas to remain as performance differentiators, and make others standard to save costs and equalize the field, so can't say I'm surprised.
Now F1 being F1, the question of who wins the tender is huge and how exactly will this gearbox look like, because there's advantages to be gained, which team is most comfortable with the design that comes out of this... I expect a lot of politicking to be going on to influence this tender.
