“Yesterday we had a battery issue on Lance’s car, and we had another battery issue today on Lance’s car,” said Orihara after the race.

“At the moment, we know what happened, but we don’t know what is the root cause.

“So we will check the data, and also we will check the battery. It may take a few weeks to find the root cause.

“But from the data, we need to find some counters for next year, and also we need to find the actual root cause of this error for next year, otherwise we’ll keep having the same issue.

“So this is quite important for us to understand what is the root cause.”

Honda CEO Toshihiro Mibe was on the ground at Interlagos, Orihara noting that this misbehaving battery was not an ideal occurrence in front of the boss.

Nonetheless, he pointed to the positives of Mibe-san’s presence and the future benefits for the Japanese manufacturer.

“Of course, in front of our CEO Mibe-san, always we are excited and it gives us some passion.

“But on the other hand, we had a battery issue twice this weekend.

“But still, positive point, he knows what is happening at trackside. So I think still this is a positive point.

“He understands what is happening at trackside, so I think he will bring this experience to the Japan side and also boost our development. So I think everything is positive for us.”
