Honda thought F1 progress for 2017 would be 'too easy'

Honda Formula 1 chief Yusuke Hasegawa has admitted the Japanese manufacturer thought developing the engine technology required to catch its rivals this season was "too easy"

Honda thought F1 progress for 2017 would be 'too easy'

Hasegawa said at the launch of the McLaren MCL32 he thought Honda's new engine would match Mercedes' 2016 power levels by start of this season, but it has endured a disastrous start to 2017, lacking performance and reliability.

Under the skin of Honda's latest saga

Neither McLaren driver suffered an engine failure in the Australian Grand Prix, but Hasegawa admitted the current engine is down on power and says Honda underestimated the difficulty of finding more power without introducing new problems.

"As a matter of fact we were thinking [it was] too easy, and it was too difficult to achieve the new technology - that was my mistake," Hasegawa told Autosport.

"We did some good progress in the mono-cylinder on the dyno, but as soon as we complete the V6 engine we had many issues.

"What we achieved in mono-cylinder is at a very good level, but when we transfer exactly the same specification to the V6 engine it doesn't work.

"We are very disappointed. But it was too late that we noticed that - at Christmas.

"After we understand the issues this was the time we need to confirm the final specification - we needed to have some compromise."

Honda has encountered further problems with instability and vibrations since the engine was installed and run on track.

"We have huge vibrations," added Hasegawa, who says Honda's new engine currently produces "almost the same power" as the 2016 unit.

"The only thing I can tell is that on the dyno we didn't have such a big issue - when we have a gearbox, driveshaft and tyre it has some resonance.

"I'm not blaming the chassis; we have to realise the situation on the dyno as well."

HONDA'S UPGRADE PLAN

Honda is working on an update package for the engine, which Hasegawa hopes to implement by May's Spanish GP at Barcelona.

"If we find a good solution we need to change the engine for round five or six, so I really want to update our specification before then, or to that time," he said.

"We have already achieved some good level of performance with the mono-cylinder engine. The thing we have to do is transfer that technology to the V6.

"Although we still have to improve that, we have some confidence we can achieve that level."
