Honda F1 project leader Yusuke Hasegawa has outlined a number of reasons why Honda has been struggling so badly in the beginning of the 2017 Formula One season. He confirmed that lots of problems were not discovered while running on the dynamo meter.
Well i expect Renault and Ferrari to start the season with more or less same power as last years with improved reliability. Apart from Merc, all others were focused on reliability over the winter break as per reports. I was hoping Honda make a jump this season, we will see in Barcelona testing.
No completely truth that the MGU-H was the only problem. It was also the oil tank and vibration... at least. https://www.autosport.com/f1/news/13086 ... 7-troublesSquid wrote: ↑16 Feb 2018, 06:23And even when the TC and ICE survived, might as well change them for new units since they will be starting at the back anyway. Good for implementing small upgrades and to get more mileage out of the parts.GhostF1 wrote: ↑15 Feb 2018, 22:28This has been discussed to death. The major Achilles heel was the MGU-H, it was literally the root cause of failure 99% of the time, I believe Canada was an actual ICE issue where Hasegawa was quoted as being shocked, as it was the first time they'd seen this issue before.Big Mangalhit wrote: ↑15 Feb 2018, 18:03Since they used something like 9 ICE's and TC's I don't think MGU-H is the only thing they need to improve. Also it's hard to predict what will happen in the tests- Last year by this time everybody was saying they needed to improve energy deployment and efficiency and nobody was saying they needed to improve the oil chamber and MGU-H bearings. And yet they really needed to take care of that and almost had no teste because of such. Hopefully this year they'll start with the right foot.
It was developed by McLaren and other outside companies. The issue was exacerbated by the oil blow by from the Honda PU. Hard to fine tune this when it isn't your own component.
Several occasions the MGU-H detonated and terminally damaged the entire PU due to its location.
Honda have since stated they intend to utilise their own design they have been working on, however they also said some of the "Hybrid componentry" will still need to be sourced from McLaren at the start, but it will eventually become an entirely Honda affair. When that will be, I'd probably think mid season. Either way, bring on the car reveals, testing and the Aus GP pls. This wait is killing me now
The engine component usage chart made the other components look unreliable when they were actually fine.
Just to clarify something, the official appointment of Marko is from the RACER article.McMika98 wrote: ↑16 Feb 2018, 00:16Sadly, it appears the new Honda unit will be trialling all 3 other manufacturers like it has done the last 3 years.The nightmare still continues in 2018 by the looks of things.
Straight from the horse's mouth, Dr Marko is quoted on amus that after having run RA618 equivalent (spec 4,5.0) on test benches, he thinks that Honda may catch Renault around midseason! So i guess all the pre season hype and speculation can go straight in the bin. Merc having proven reliability last year, will most definitely raise the power while the remainders try to get the reliability in place. Its going to be another Mercedes domination, yawn.
Correct, nobody expects anything from Toro Rosso. They were fighting with Sauber at the end of the last year. That's probably a good thing for Honda, less pressure. I really hope they will show some major improvements, but reading these stories about a big update in the second half of the year, sounds like a story that we've heard before.Big Mangalhit wrote: ↑16 Feb 2018, 11:14No completely truth that the MGU-H was the only problem.

Also Honda used 8 and 9 MGU-K; and 7 ES/CE in their cars, which are quite separated from the MGU-H. This year they can only use 2!!
You can claim that they did it because they already had penalties but truth is that EVERY OTHER CAR used only 4 of each of these components with some of them only using 2 of the ES/CE!!
So even tho all 3 other manufacturers show great reliability on all parts (especially MERC/Ferrari which out of 12 cars only Vet and Ham got a single penalty) Honda is still a big question mark. I am all for wishful thinking but if you think that their problems were strictly coming from the MGU-H I think you are completely wrong.
Luckily it is possible that they solved their combustion principles and that operations run smoother this year, also maybe they'll have and easier time integrating in a more low pressure environment of STR. I mean who the hell would care if Brandon Hartley were saying he was on a GP2 engine...
You make the same point which is, Honda will start 2018 season behind every manufacturer. Spec4.0 was last years engine so the new engine will prolly be an update as mentioned here but alas it just does not appear to have the power to dream of.HPD wrote: ↑16 Feb 2018, 12:23Just to clarify something, the official appointment of Marko is from the RACER article.
At no time speaks of the 4.5 engine or test in a bank.
He says that with the second update of the "new" engine can reach Renault.
The second Honda update we do not know for when it is. But I think it will be the gp of España.

Especially for winter testing I bet they will want reliability before power.McMika98 wrote: ↑16 Feb 2018, 19:12You make the same point which is, Honda will start 2018 season behind every manufacturer.

Didn't the turbo have an internal wastegate?
