Honda introduced their 2nd PUs in France.
Max was using the 2nd PU in Silverstone, as it is one of the most power-sensitive circuits on the calendar, and it would’ve allowed him to exploit the reliability fixes introduced on the 2nd unit, which allowed for more baseline power to be utilized.
With the format of last weekend, I don’t know if the old PU1 was even used in practice. Not much time for a swap with quali and a sprint race on the same day as practices.
I can't find it but I had read all the PU are the same 2021 first iteration. No upgrades,Reliability or other, all year (excluding software).
Reliability upgrades are allowed and other teams are made aware of what the improvements will be and have the opportunity to object. If a reliability improvement lets you utilize a more powerful engine map, then that’s fine.
Pretty sure reliability was for post 2022

However, speaking at the Austrian Grand Prix, Honda F1 technical director Toyoharu Tanabe denied that there had been any change to the engine specification, nor that it was running its power unit in a more aggressive manner.
Asked about the rumours of a 15bhp jump with the second specification unit, Tanabe said: “I'm very happy if it is true, but it's not true.
“Under current regulations, any performance update is not allowed to apply during the season. As a result, our second PU is the same as first PU in terms of specification and the performance.”
