Realistically, how much can the MGU-K recover per lap? I've been working on the assumption that 2MJ was a reasonable target for a +/-120kW K for the 2014/15/16 cars, but I don’t think it’s achievable at most tracks for the 2017 cars as they don’t hit the speeds that they previously did and also the ’17 cars carry much more speed through corners, so, less opportunity to recover.
Now, with the 2021+ suggestion that the H could be scrapped, I have some questions:
How will they recover the required energy? A larger K is obviously the answer, but how big can this unit realistically get?
Could the K be asymmetric in its M-G relationship (say 240kW recovery, 120Kw deployment)?
To my mind, 4MJ per lap recovered from a 240kW K would only be achievable if the cars go back to less DF. Even then I’m doubtful...
