Honda admits it's still not ready to supply a second F1 team

Under new rules approved last month, all four manufacturers - Mercedes, Ferrari, Renault and Honda - have agreed on a principle of obligation to supply engines from 2017.

The FIA also has the power to compel the manufacturer with the fewest customers to supply a team that needs an engine.

Speaking before the new rules were agreed, McLaren chairman Ron Dennis told Autosport's sister title F1 Racing only once McLaren-Honda has won the world championship will it think about supplying a second team.

Honda has maintained it is open to supplying another team but Hasegawa conceded the Japanese manufacturer isn't currently in a position to do so.

"I have an obligation to contribute to F1 society so we are preparing our resource," he said.

"But still we are not strong enough to provide for a second team. We are preparing now."

Hasegawa added while Honda had had conversations about a second supply, there have been no formal talks.

"We don't have concrete negotiations," he said.

"Although we have some conversations with some teams, unfortunately, we can't make a conclusion with other teams.

"That is our current position until the situation changes."
