The old thread was getting a bit long so, like Liberty Media's ownership of F1, this thread can be a fresh start. Here's the latest:
Formula 1 2021 engine rules revamp details revealed
The proposal for 2021 includes keeping the current 1.6-litre V6 turbo hybrid engine, but running it at 3000rpm higher "to improve the sound".
In order to try to simplify the internals of the power unit, the MGU-H will be removed, and several prescriptive design parameters will be introduced to "restrict development costs and discourage extreme designs and running conditions".
These will include internal and external parameters, with the latter allowing for what the FIA described as "a plug-and-play engine/chassis/transmission swap capability".
The MGU-K will be made more powerful, with a focus on manual driver deployment of the additional power, similar to the way KERS was used when it was first introduced into F1 in 2009.
This feature will also give drivers the option to save up energy over several laps to increase the tactical elements involved in racing.
Sp where are we? Ross Brawn says F1 is at a crossroads, and wants this little old engine to reduce costs, make car performance more equal, inspire more fans, rev higher, and generally lead the F1 paddock into the promised land.
Ferrari are threatening in the vaguest terms possible to walk away from F1. Mercedes and Renault have reservations too.
Aston Martin, not a major car manufacturer but perhaps that's the point, are "encouraged" by the noises coming out of Paris.
