German SportBild too reports the Problems lie in the Cylinder Head, specifically with the new Injection Technology. That supposedly was the cause for the Day 2 and Day 5 Engine Failure.

Wasn't yesterday's "failure" an electric issue and they changed it as a precautionary measure?

Apparently the "electrical Issue" was just some PR spin...

I wonder if the 2016 PU could fit the new McLaren, and whether it would be a better bet for the first few races. Hold off the 2017 PU until it is reliable, an introduce it in Spain.

I think that level of repackaging would be practically impossible, given the layout change and time available.

Even if the layout was broadly similar as last year's engine (and we know it isn't), this would still be practically impossible.
There are 16 days left before Friday practise for the first race.
I don't think something as simple as a new airbox could be done in that amount of time, never mind everything inside the sidepods and above the PU; that's folly.

To do this sort of repackage as a real rush job would take about 3 months at a minimum, even if you had started with a chassis design where the criteria was to enable this sort of thing to happen.
Look at Lotus (Renault) moving back from the Mercedes to the Renault PU from 2015->2016 for an example of the compromised result (even if you can move mountains and make the new PU fit, it will still be so poorly packaged, it'd always be a chassis compromise anyway, leading to performance deficits).
In 2015, while designing their next car, Lotus knew they were potentially going to be using Renault PUs in 2016, although the car design had been started and largely developed with the Mercedes PU in mind. Remember the Renault letter of intent was only signed at the end of September 2015 - by which point most teams have done a large portion of the car design, issued build subcontracts to suppliers and so on already.
I think in 2017 there's no way McLaren will have left any space available to suit the 2016 Honda PU "just in case they need to fit it"; it's just not how they work at all.

According to the google translate of that article, "Tokyo is on another night shift". Sakura isn't anywhere near Tokyo?

Well, Honda is headquartered in Tokyo, so they probably made a genuine mistake.
Alternatively, they mean that the management will have a late night over this increasingly embarrassing endeavour of theirs.

I trust more info here on forums then AMUS. Clickbite journalists!

So basically despite Honda stated several weeks ago they were assuming a high risk bet with the new PU...

It's very high risk, we don't know a lot of things about that new concept.

http://www.autosport.com/news/report.php/id/128097
... even so you all find it unaceptable to suffer some problems in testing?


Then sorry guys but the problems is yours If someone is expecting any manufacturer to catch up Mercedes without assuming risks and making mistakes, we must be living in different worlds, because to me engineering is exactly this, trying different routes, assuming risks, making misgtakes and learning from those. I did assume a long time ago this would be a long and extremely difficult race, as any other where someone make an awesome job (Mercedes) and some competititors try to catch up desperately

Maybe you were not used to this after the ridiculous engine freeze we suffered in V8 era, but this is F1 too

AMuS surely is not a clickbait Tabloid. Check your Facts.

It's better to have the same Failure again than the one on Day 2 than a completely new Failure on Day 5. It was the old Engine config after all. So the AMuS Story is actually better for Honda than the electrical Failure Story.

Exactly! I just don't know why they said McLaren had 2 problems yesterday. Maybe we didn't hear about one of those.

From autosport:

McLaren says that trackside impressions its 2017 car is nervous are Formula 1's equivalent of 'fake news', as it blamed Honda's driveability for the issues.

Fernando Alonso and Stoffel Vandoorne were observed having a difficult time manhandling the MCL32 during the first week of testing, with Autosport's technical consultant Gary Anderson saying "this is not just a very good chassis being let down by the engine".

That impression countered comments from the team that the new chassis had delivered all that was expected of it.

Asked to explain the discrepancy between the team comments and what was happening on track, Boullier said that the characteristics of Honda's new engine were having a big impact.

"Well, strangely, the car reacts well to any changes that we have asked. The drivers on that point are quite happy," he said.

The crisis deepens at McLaren-Honda

"I read some comments [about handling difficulties in Turns 1/2/3] and they are a bit like [US President Donald] Trump's 'fake news' - because it is not only chassis.

"Remember these engines are hybrid engines, which means when you are very early back on throttle you have electrical power which is on/off.



"And then you have a turbo as well at the back - so depending on your driveability there could also be some issues.

"We had some driveability issues, which means when you are back on the power you lose the back of the car so the car looks nervous. But there is nothing wrong.

"Driveability issues, old tyres, let's say, warming up the tyres is not good enough.

"But still the car spec here is launch spec, we do try little bits, but we will not run the full spec. The full spec will be run in Australia."

So its not just the reliability. The engine is undriveable

Sorry! You need examples? This is clickbite: "The crisis deepens at McLaren-Honda"
And this for example:
"Honda worried about its Australian GP engine spec after test issues"
is another article bused on same (few days old) Hasegawa interview! And its not what Hasegawa told. And actually its even not what article is about!

So please Check Your Facts!

Talking about checking facts...
You specifically mentioned AMuS and now you come up with headlines of autosport.com. What has that to do with AMuS?

Let's get back on topic fainting daisies...

Alonso still lapping in 1:34 this morning. Extended periods back in the garage. New spec PU?

Reports say new engine will arrive tomorrow, hopefully they can run it on the day, as for now they are running one of last week's with some tweeks I assume.
