Honda and McLaren have reached the crossroads, with a crucial couple of months ahead which will either make or break the relationship.

The partnership appears in jeopardy after McLaren boss Zak Brown said earlier this week that the Japanese manufacturer appeared “lost” and that “difficult decisions” would soon have to be made.

Honda F1 chief Yusuke Hasegawa says he understands McLaren’s frustrations, but also the need for big improvements sooner rather than later.

“It is very unfortunate we can’t convince them that we can do that,” he said. “From the results point of view, of course we need much improvement from the performance and reliability point of view.

“So we will do everything. We need to do everything.”

“Of course, we are talking together, even this morning, and it’s obvious we are frustrated with the current situation and are disappointed with our team result,” said Hasegawa.

“So there’s no wonder there are some complaining comments. But the things we can do is trying our very best for the team and we are still aiming to go the same direction.”

With pressure mounting, McLaren had been anticipating a substantial upgrade of its power unit in Montreal, but Hasegawa conceded that no date of delivery could be provided.

“When we are ready we will introduce it, unfortunately it has not happened here,” said an uncomfortable Hasagawa.

“However, we are still trying hard in Japan and as soon as it is ready we will introduce it.”

The wait continues, but with each passing day, the McLaren-Honda relationship dissolves…
