Yes. Given the lack of testing outside of racing, and the 23 race calendar next year, the teams kind of have no choice but do some of this.

Yeah, I think so too ...

I also suspect sources that are able to specifically specify what the problem is. Anything I can find is innuendo from mysterious or non existent sources.dans79 wrote: ↑22 Oct 2021, 20:31This it the bit i find highly suspect, as the first PU did just fine.atanatizante wrote: ↑22 Oct 2021, 20:23The same rumours are also saying that 2021 Merc PU having to cope with more races/km than last year was wear out at a faster rate towards their end of the duty cycle than it was designed for and the reason for that is the fierce battle between them and RB/Honda, which forced them to use more and more aggressive PU mappings in races, all coming with some negative consequences: they have found some issues at the crankshaft and valve seats ..."
It ran every free practice, qualifying session, and race for the first 5 race weekends. It was then relegated to fp1 & fp2 duty till Spa, so it did another 6 fp1 and fp2 Sessions.
The numbers just don't add up to me!
or they do if you have a different perspective of it, sure they were doing fine with the first power unit but at that time while in the hunt it was clear RB was getting the better of them. Last little bit Mercedes has found much more pace and that coincides with this sudden pu unreliability. Unless we are engineers on the team nobody can really know for sure but seems a very plausible narrativedans79 wrote: ↑22 Oct 2021, 20:31This it the bit i find highly suspect, as the first PU did just fine.atanatizante wrote: ↑22 Oct 2021, 20:23The same rumours are also saying that 2021 Merc PU having to cope with more races/km than last year was wear out at a faster rate towards their end of the duty cycle than it was designed for and the reason for that is the fierce battle between them and RB/Honda, which forced them to use more and more aggressive PU mappings in races, all coming with some negative consequences: they have found some issues at the crankshaft and valve seats ..."

Both Merc and Honda had run their first spec in conservative/detuned PU engine modes in the first 7 races of the season, bearing in mind they have to do 22 races this year with just 3 PU and they also need to do some testing with the new E10 fuel for 2022 ...dans79 wrote: ↑22 Oct 2021, 20:31This it the bit i find highly suspect, as the first PU did just fine.atanatizante wrote: ↑22 Oct 2021, 20:23The same rumours are also saying that 2021 Merc PU having to cope with more races/km than last year was wear out at a faster rate towards their end of the duty cycle than it was designed for and the reason for that is the fierce battle between them and RB/Honda, which forced them to use more and more aggressive PU mappings in races, all coming with some negative consequences: they have found some issues at the crankshaft and valve seats ..."
