HRC boss Koji Watanabe's interview after race,here is the main point.
1.The vibration was significantly reduced during Aus GP than Bahrain test.Lance said he felt the vibration level was almost half(of how he felt during Bahrain test)
2.The target is solving the vibration problem in Japan GP.
3.No PU issues in the race.Our part of race plan was doing some test because we didnt do much laps(in Bahrain test),the other reason was the team's strategy(to retire the car).
4.The PU was still runing with some limition.When the vibration problem is completely solved,the PU will be operating at its full capacity, then we can check the real performance of the PU and we will know which era we should improve.
5.The number of engineers in F1 project is enough now(With more engineers return to F1 project,Now the number of people in F1 project is almost same to 2018-2021 time.).We will do some organization change to Improve development speed and collaboration with Aston Martin. I'd like to discuss it with Mr. Takeishi (Ikuo / Executive Officer and Director of Honda Racing, Head of the Four-Wheel Racing Department).
