Sustained, and if true it slashes their current deficit by more than half. Honda needs to take an additional 20kw step after this to catch the leaders.

Hi wazari, have you got an idea of the honda turbo size for 2018. mercedes turbo is the biggest , is honda going to introduce a bigger turbo relative to mercedes next season since they are running a similar layout design.

20kw is about 0.5 sec on BCN, so if their packaging still the smallest, RBR may take honda engine happily. Very happy to hear that. I wonder how much difference spec 3.8 this year compared to spec 3.5 2016 engine. And Honda spec 2xx is really suck afterall, no wonder MCL want diforce

Wazari, now that the season is over. Can you give us some figures about the difference in performance of the current 3.8 and 4.0 specifications?
Hasegawa always wanted to introduce the 4.0 in 2017, and "catch" Renault.
25 to 30 kW.
Sounds close to the bump Renault were said to have received when they changed their combustion concept a while back. Thanks.

Don´t forget that the other manufactures will find some gains on its new developments, so I think it would by fair to assume that Honda could cut by half their deficit, but like this is moving target, Honda will find some gains in other areas as well.

Wazari implied there were further advanced stages when he said Spec 4.0 and Spec 4.xx.

One would assume that by testing the engine would of made even further progress.

According to Wazari, the Spec. 4 concept existed in some form at or before winter testing but it was not chosen due to a number of factors (weight, CoG among others) despite a supposed power advantage. Fast forward to the end of the season where Hasegawa said a Spec. 4 engine was ready to use but ultimately was not, presumably because of chassis modification and/or penalty considerations. We can then infer based on Wazari's use of Spec. 4.xx that, like any good development engineering team with a moving target, that they have not been sitting still with the new power unit even if it hasn't run on-track yet. This could be another contributing factor to Honda not to bringing Spec. 4 when it was ready: it may have shown McLaren something they were not privy to yet and Honda did not want them to see with Renault in the picture.

Look again. The Honda 2017 turbine is just about the same size as mercedes. Millimeters in it.

No spec 4 in 2018? So 2018 is 3.9?

Spec 4 is a version of the RA17 engine.
2018 will have an evolution of Spec 4 and whatever it is they have on the dyno in Sakura. That engine spec will start over at Spec 1. Remember the 2017 engine is the first of the concept. There will be major changes for the 2018 engine even though the architecture will be similar.

That is naming problem only :lol: yeah, their first iteration in winter testing would be spec 1 2018,for sure

Honda F1 chief Hasegawa to leave role in overhaul

Yusuke Hasegawa will leave his role as head of Honda’s Formula 1 project at the end of his year as part of a management structure overhaul.

Hasegawa has faced growing pressure over the course of this season as Honda struggled with both power and reliability and culminated in it ending its relationship with McLaren after three seasons.

Ahead of the start of Honda’s new partnership with Toro Rosso, the Japanese manufacturer has announced changes to its organisational structure in a bid to turnaround its fortunes.

In his role as head of F1 project, Hasegawa was responsible for both engine development in Sakura as well as the race operation. That role has been removed with Honda splitting the responsibilities to create two new positions.

Toyoharu Tanabe has been named F1 technical director and will focus on the racing and testing operation at the circuit.

Autosport has learned Yasuaki Asaki will take the role of operating officer at Sakura in charge of Formula 1 engine development.

Tanabe, who has worked for Honda since 1984, has F1 experience, having worked as an engineer for Gerhard Berger at McLaren and as chief engineer for Jenson Button at BAR and then Honda.

He also worked in Indycar, currently holds the role of senior manager and race team chief engineer for Honda Performance Development and is believed to be highly rated within Honda.

Hasegawa, who took over from Yasuhisa Arai in early 2016, will no longer be involved in the F1 project but hold the role of executive chief engineer.

Honda says he will use his experience and knowledge from the F1 project to work on various global research and development projects focused on future mass production. The trio will take up their respective new roles on 1 January.

“In the past, the head of F1 project assumed responsibility in both technological development and directing the team at the spot of racing,” said Honda chief officer for Brand and Communication Operations Katsuhide Moriyama.

“By separating these areas of responsibility, we will evolve our structure so that both the development team and racing/testing team can assume their respective responsibilities more speedily.

“By ensuring both the development team and racing team soundly fulfil their respective roles, Honda will continue its challenges so that fans can enjoy seeing Toro Rosso-Honda competing at the top level without further delay.”

Not sure how I feel about this... Was Hasegawa just the fall guy to make the engine concept transition, take the blame and then make room for the actual boss?
