Just now watched Sam Collins on F1TV, he mentioned that PU1 was used after Spain failure in Monaco and Baku. I don't think he is right regarding Baku.dialtone wrote: ↑Wed Jun 15, 2022 9:24 amThat information is obviously not correct. All press is reporting that the reliability upgrade from Ferrari didn't work, and that was in the PU2. Ferrari isn't going to run PU1 on a track like Baku, the last track it did was Monaco.F1NAC wrote: ↑Wed Jun 15, 2022 8:08 amWhere did you get that info? If that was indeed PU1, which started with lower power than PU2, that is then surprisingly good from a performance point of view, given how quick they were on the straights.saviour stivala wrote: ↑Tue Jun 14, 2022 7:06 pmUnlimited upgraded for reliability reasons are allowed. Rivals cannot stop them, only FIA decides. Leclerc used fully upgrades PU 2 in Miami and for 20 laps in Spain. In Baku Leclerc was using PU 1. In 5 days after Baku FERRARI needs to declare whether the failed Baku PU 1 can be repaired. If not Leclerc will be issued with PU 3. The problem is the Turbo. If the turbo used in Baku cannot be used Leclerc will have incur a grid penalty.
