Mclaren MP4-30 Honda

[iichel]

shouldn't these calculations also be considered with downforce levels? maybe the merc simply has less downforce bolted on? or the ERS deployment strategy is maybe different?

On that particular lap maybe they decided to try the real potential of the PU for one lap.

i suspect the same , if this is the case then it bodes well for future but if they are seriously thinking of challenging mercedes next year then they need a flurry of these kinda laps in near future. i hope mystery around that lap can be revealed soon.

[max_speed]

If this was the case then surely they could perform a little better in qualifying over 1 lap ?

i guess they want to test PU over race distance , even running at this level would not have landed them anywhere considering penalties that were well decided at that time. new ICE its better to accumulate mileage and turn on for one lap in full mode to see , data spikes across all components and verify their terminal boundaries.

It was the 5th fastest time. Quite a good lap actually, the very thing is though how he did a 53.6 then next lap and for the rest of that stint was in 56's nd 57's, i.e. 3 - 4 seconds slower... something really strange going on. It does suggest there is a lot more potential there.

Perhaps he got a slip stream in all the straight line sections?

Its down to engine after all...

Can't be just the engine. Through turn 18 Rosberg srubs off 1-2 kph, which he immediately gets back. Alonso scrubs off 10 kph! And they both seem to have the same breaking point, despite Rosberg being 30 kph faster at that point.

Can they do something whit software to fix these ERS problems?
Or is this a fundamental mistake in design of Turbo/Compressor/brake/exhaust systems that poweres the ERS?

Yes, few bug fixes and they'll be p1 before you know it.

I'm still afraid there is something fundamental with the tight packaging, all these gizmos needs cooling, including the MGU-K.
A 95% efficiency of a 120 kW unit still means that it generates 6 kW of heat, like a dozen toasters, while 95% is very good.

The same goes for the MGU-H, battery and electronics, and these compoenents don't appreciate getting too hot.

This is stuff that you might undervalue on the dyno, but when installed in a "size0" rear end of a car, it might be troublesome.

That lap was really weird. It was the 1st full lap after last pitstop and he made (S1/Speed S2/Speed S3/Speed Full LAP)

L35 32.627/296 50.779/191 30.286/208 1:53.692
L36 33.118/291 52.340/186 30.885/210 1:56.343

He was nowhere near any other car, so slipstream is not a factor. The Mercs were closing in behind to lap him and he was blue flagged on L37 and lapped by HAM just before the chicane. He stabilised on 1:56 or higher after that. I do not think 1L fresher tyres justify 2.7s !!!!

That Tray was present in the Last race right? I think i saw that before. Here's a drawing of it.

Just a glimpse, I don't know if it has been commented previously, but If there is a temperature problem, why the holy --- this card is painted in BLACK????

The colour of the bodywork makes a negligible difference on internal components' temperature. Otherwise every car on the grid would be painted white, or some reflective paint.
