Renault Power Unit Hardware & Software

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

Mercedes is doing ok qith split turbo.
It failed on Valteri's car. How many times did the Ferrari's turbo fail this year ?
When it is so close 1 DNF is unacceptable.

Ferrari have almost equalized with a normal 'short' turbo.
What are you talking about? Ferrari has had a number of turbo problems this year.

True! But let's see about grid penalties later this year. When did Mercedes DNF btw? (Must have missed it.)

In Spain.
I am not denying split turbo advantages, I am just arguing that it is a massive liability that not even Mercedes have sorted. There's probably development paths that can yield larger gains for less effort.

Oh and we are in complete agreement there. I think Mercedes even admitted that getting that to work was Very Hard. My entry here is that it is also my impression that Ferrari has had some serious trouble with their turbos this year. But also, really, that their engines seems to work very very well!

Because they were lucky. Ferrari had had at least 2 turbos failures in FPs, but none in the race and will have further penaltes coming up. I think after 3 years of Mercedes' almost (!!) bulletproof reliablity it's quite hillarious you're saying 1 dnf is unacceptable lol.

It is important in the current context - if Hamilton's turbo had gone instead it could have costed him the WDC.

Oh yeah and remember one year ago when his engine failed arguably losing him the WDC ? I bet he found that 1 DNF hilarious.

I said almost bulletproof for that exact reason. Because they're not 100%. Also, that engine alone did not cost him wdc, but that's a whole different story.

Anyway, I'm not sure whether or not those failures came from split turbo design, but chances are slim. I know the reason was given back then, but I can't remember what it was.

Bottas' engine this year blew up because it was over it's speficied mileage, and that was known.

Which is why I said 'arguably' - but it is a very good example where 1 DNF is one too many.
And yes - you are spot on - they are not 100%. But Ferrari have a perfect PU record so far (FP failures have not costed them anything just yet).

And all turbos are currently available to them.

One turbo was used when they had to change Seb's ICE 2 back to ICE 1 at the Spanish GP just before qualifying. The turbo on ICE 1 was new because of an issue they had earlier and ICE2 had oil leaks - so nothing wrong with the turbo.

Seb's ICE 1 did go over the planned mileage too.

Valterri had to change his new engine because of water leak, then he went to the old high mileage one and that was the one that failed. Still not bad of a failure rate considering.

Everyone is looking pretty reliable this year.
With the exception of Honda of course :D

Next year they will be penalized to go beyond 3 engines! So more of a lottery at the end of the season, and here I thought Bernie wasn't active in the sport anymore. Guess not.

It will make things more interesting for sure.
Sadly we might see slower cars next year as a result even with the "same" engines.
They won't push them as hard .
