McLaren and Honda insist that the 2015 project has not suffered because of the lack of a second team to help log mileage on the troublesome new power unit.
Honda F1 chief Yasuhisa Arai says that there is still no plan in place to expand to a second supply for next season.
“It’s a good idea but we don’t have any such kind of plan,” said Arai. “I concentrate on McLaren-Honda, one team, that’s it.”
“I do agree with Arai-san,” said McLaren team boss Eric Boullier. “I think the project is not mature enough to take over a second team. I think a lot of [the] job can be done on dynos before we think about having a distraction of a second team.”
