2018 McLaren F1 Team - Renault

Mclaren need a bigger airbox. The airbox is much more important in the modern formula then the rear wing is. The engine, batteries and ers all need much more air for cooling and these are important performance items.

Do they speak english in What ?

Bad batch of the battery caused the 2 failures today according to Renault and it had nothing to do with the installation of the battery.. The hydraulic leak is still a toss up on whose fault it was but I have a feeling the need to change the battery probably precipitated it.

Hydraulic leak was a fatigue problem according to Boullier.

fatigue on part? Or fatigue on mechanics from having to work on battery twice in one day?

If on part, what part?

[Webber2011]

Hydraulic leak was a fatigue problem according to Boullier.

If they are having problems with fatigue after so few laps then it must be either a badly designed or badly manufactured part.

I wonder what actually failed ?

Another $2 part ?

Is all this with McLaren saying their problems are a lot to do with McLaren ? With Honda being a very unfortunate (bad engineering) coincidence.
My opinion is that it is and has been since and just before Martin Whitmarsh days, did Bruce have any children?

Stepping in here with that statement must be like sitting in the wrong stands at a manchester liverpool game i imagine

Today's issues 2 out of 3 were battery related which were Renault part. Renault took full responsibility for it. Said it was a bad bath and installation had nothing to do with it.
This is literally the 3-4th time I am posting this here. Hydraulic leak on the other hand we dont know was a Renault issue or McLaren issue.

more air more air!!! dont they know f1 is now about MORE AIR!!! ≈ç , ç≈

Well it at least seems that none of the problems are being caused by the cooling, which is a good thing.

The validation method for batteries is quite interesting, Renault do it itself with a live stress test, then they select the best candidates. Theses methods from electronic industry are far way form classical methods used in mechanic area such as metrology / x ray inspection.

Curious that the only teams with battery problems are costumers Redbull and Mclaren, I guess Renault gets the best from the validation tests

you are right

Red Bull then lost out on track time in the afternoon as Max Verstappen brought out the red flag. All three stoppages were attributed to problems with the battery, however Renault insisted it is not a big problem.

"The issues that we've had I don't think have any relationship to the installation of the battery at all," said Renault chief technical officer Bob Bell.

“We (the works team) haven’t had any problem, but what we do ahead of Melbourne is that we try and shakedown all of the battery systems to make sure all of the stock that are going racing are in good shape.

“That’s why we test them here. We revolve them around the customer teams and ourselves to make sure they are all tested ahead of Melbourne. So it’s not unusual to find issues.”

Bell said Renault's two customers receive the same specification as the works outfit and sees the problems as a positive as it means the French manufacturer can remove the problematic units from the pool.

I don't understand the battery story. They are 'tested' in testing to validate them before using them in the races? Can't they design/protect them so they don't break brutally to stop the car completely. For example run in a lower configuration so the car can at least do some other testing without being halted completely. That way the battery can be changed later on. I also don't understand why batteries need to be 'tested' or selected like this. It's like saying 'we made 10 but 5 of those won't work, go figure out which ones, good luck'. It just doesn't make sense to me. They should have enough data to do such a thing on the bench I would assume.

What is the point for them of running on SS whole f1test? Its not like they will use that tyre regulary in calendar

It's the method chosen by a socialist company form a socialist country to ensure equality for both.
Now imagine that changing a battery is a well known method for Redbull, when it did appears the fix it in less than an hour.
Imagine that it takes twice for McLaren people to do the same thing, and because of the big pressure they have on them, they didn't plug correctly the cooling system to the new battery.
Imagine that a simple technical issue become a big drama for McLaren in the hysteric social network background.
In fact McLaren loose one day where Rebull didn't for the same thing.

Autosport:

Definitely hypersofts on the McLaren. Boullier explained yesterday that it's not a performance thing, rather a need to get the tyres working quickly when they are planning testing things around short runs. Sometime a 10-lap or 12-lap stint isn't what they want to do, but that's what they'd need to have the tyres working properly.

Really hope it's not the normal Boullier BS
