From 2027, the homologation of gearboxes will also be eliminated, to ensure greater development freedom for manufacturers.

track specific gear ratios will be back.

Another odd decision by the rule makers.

I guess we should expect EVERY previous rule that wasn’t implemented under Liberty media to be changed in some shape or form.
I look forward to seeing the all wheel driven 8 wheelers.

For the manufacturers that develop their own gearboxes, it's very good. For the gearbox customers (alpine, Haas, Williams, Cadillac), it's very bad.

For Mclaren, it's somewhere in the middle because of how PU and gearbox are integrated.

I know but there’s no need for it.
Homologated boxes have been fine- they where introduced to keep costs down, no?
We are now in a cost cap era- let’s open up gearbox development.

but that does make sense. Personally I think it's going to create two problems.

1) Team like Mclaren is affected to lesser extent, but PU power band developed around anticipated track specific ratios. It's just another thing that the factory team understands intent much earlier than the customers who can make their own gearboxes, and then those who buy them are shut out entirely from this design freedom.

2) This track specific suiting of the homologated gearboxes may have led to different race winners this season. With the best team also being able to run the best ratios at every track, there is inevitably less variability in race winners. We see that effect to some extent already with the lack of aero compromises required between low and high downforce tracks because of active aero. The top team can increasingly have the optimum configuration to exploit their cars at every circuit.

Gear ratios don't fall under the homologation. From the 2026 regulations:

C9.4: The design of the Driveline Components (with the exception of the gear ratios, for which the
provisions of Article C9.6.2 apply), Gear−Change Components and Auxiliary Components must be
homologated by each gearbox supplier before the start of the season following the season when
they first supplied a Gearbox under these Regulations. The design must not be modified, except in
exceptional circumstances, in subsequent seasons.

The currently available 2027 regulations allow one single update during "this" four-year period.

The gear ratios will likely still be fixed during the season.
