So this is what Brawn claimed in a recent article
“They will be noisier in 2021 and they will be more powerful,
“We are also putting more emphasis on drivers to control some parameters of the engine such as energy recovery, which comes from battery and hybrid motors, more of that will be under the control of drivers. So you can do things strategically to overtake. Everyone is on same page now, we have agreements with manufacturers.”
I wonder how they want to increase noise , when apparently the essence of the formula stay the same because the manufacturers wishes. So we'll still have the two MGU-s and fuel consupmtion limit.
Will they add an acoustic horn at the end of the exhaust?
I guess the power increase was implied by the gearbox tender that suggests a more powerful mgu-k.
The energy recovery part is a bit weird. I guess it can't include H since even software had difficulties with it in the beginning. A second brake pedal for re-gen breaking? It'd be a tad odd.
Or did he just misspoke and thinking of a KERS-like deployment?
