I like most of f1 2021 engine ideas more RPM, less cost, no MGUH ,standardized energy store & electronics. these hybrid engines are fantastic power wise, I don't think f1 has ever been going quicker. but I am concerned at staying with v6 hybrids as petrol becoming less road relevant now nevermind by 2021 beyond but i have to trust Ross Brawn because come on that guy knows F1 as good as any he been apart of 118 races & 16 championships at 4 different teams & laid founations for Mercedes dominance of recent years.
