From part 1, yesterday:
Can you tell us what you think after the first half of the game?
Masafumi Yamamoto Managing Director (Yamamoto MD): Looking back on the first half of the game, I think the French GP was a turning point.
──What is it?
Yamamoto MD: At the start over there, Verstappen would probably be out for a moment alongside Charles Leclerc (Ferrari). I think you remember. However, immediately after that, it was torn lightly.
Actually, Honda's power unit was overheated at that time. Just for Max. I can say that because it is now. Why is that? I analyzed why this happened after the race and went to Austria.
──That was what happened.
Yamamoto MD: Originally all four units had signs of heat.
──At the previous round of the 7th Canadian Grand Prix, you had power loss symptoms.
Yamamoto MD: That's right. And in France, only Max has lost a lot of power at the start. Exactly the power loss symptom remains in the data, and why does this happen immediately after the start of the first lap. So in Austria, we took all possible measures against overheating.
Running four units has an advantage at this time, and the laboratory has verified a huge amount of data from four units. Austria was very hot, but it was set to the limit so that it could demonstrate its original performance in such an environment. That was directly linked to the victory of Austria.
At the same time, I learned that it was possible to draw performance from our power unit so far, and I was able to do a good race with England, Germany and Hungary. About the UK after the first victory, I was talking to Tanabe (Toyoharu / Honda F1 Technical Director), saying, “It ’s a power circuit, so it ’s a podium even if it works.” In fact, it was impossible to win, but it could have been second if he hadn't even hit Sebastian Vettel (Ferrari). Thanks to such a race, we felt a good response.
