Honda to try new ideas in Baharain Formula 1 testing

With Honda trying to unlock more power from its engine ahead of a planned new specification being introduced, its F1 chief Yusuke Hasegawa says some development concepts will be tried by Oliver Turvey and Stoffel Vandoorne this week to help improve understanding of what needs to be done.

"Some of the ideas [will be tested]," Hasegawa told Autosport about the plans for Bahrain. "But it will not be a totally [new engine]."

Honda had originally slated the introduction of an upgraded power unit for around the time of the Monaco or Canadian Grands Prix, but there are suggestions that an interim step could now be brought in for the Spanish GP next month.

Hasegawa has drawn short of putting a firm date on the plan though.

"We don't decide to disclose," he said. "I have my target but because it is not ready we don't say.

"I don't want to give the fans too much expectation, so I will wait."

But he has made it clear that Honda is not being conservative in its ambitions to make progress as quick as it can, after the frustrations of recent races.

"In this situation we cannot wait," he said. "We really need to have some improvement."

BAHRAIN PROBLEMS STILL A MYSTERY

As well as working on the power front, Honda is also having to address the MGU-H problems that hit both its drivers over the Bahrain GP weekend.

Analysis of the broken units both Vandoorne and Fernando Alonso suffered is ongoing, with Honda keen for answers.

It hopes that solutions to prevent a repeat in the future will be ready as early as this week too.

"Still we need a few days to find out [what happened]," said Hasegawa.

"But we really need to put something for the test, even if it for the final day."

Explaining what happened with Vandoorne prior to the start, Hasegawa said: "We don't know the cause, but the water pressure dropped....it is in the MGU-H area.

"It looks like the same issue, but a little bit different but we haven't had time to properly analyse."

Hasegawa added that Honda was surprised to suffer such failures in Bahrain, after relatively few problems in the first two grands prix.

"At first we thought [the problems were because] this was the third race, and every part mileage was longer," he said.

"But Stoffel's MGU-H was brand new here, so it wasn't just caused by mileage.

"So we are eager to find out. We don't know. We are very surprised why here we have these failures."
