Habla Arai, os señalo lo importante.
Fuel consumption was very severe throughout the race. The setting has to be such that you cannot extract the power, and the same goes for Sat and Fri. That means less fuel efficiency with the same amount of fuel, so we were running with fuel save mode almost all the way today as well. Sometimes attacking a bit but mostly running patiently. Sometimes cornering speed faster than others but overall we were running very quietly. Jenson did really well there.
Using MGU-K. But for example if you apply full power on MGU-K, then you can only recharge next, so energy wise we run it with setting that makes overall balance even. Driver worked hard with his skill, like saving fuel usage and coasting, targeting bringing the car home. Hats off to Jenson.
Race day was cooler so no particular heat issue, with water and oil temps going down and staying lower as the race went on. But as for today, it's impossible to make any changes towards the race, so you only have to race with what it is, so actually there was nothing we could do hardware wise. However from data acquired yesterday we are able to comprehend more, so we'll work on it in the next 10 days. Malaysia is hot so we're cautious.
(what is it that you found out from yesterday' data?)
cannot reveal much about technical matter in detail here, but as for engine, durability against intake air temp is severe. MGU-K as well, higher ambient temp contributes to shorter assist time and motor unit heating up. This is due to aggressive packaging. The MGU-K's motor unit is hidden in such place that you might wonder "where is the motor?", so that should be affecting certainly, but that's our unit's selling point, so we will manage to accomplish that. We are seeing prospect partly, so will take measures for Malaysia.
(Would have made any difference for today's race if you were able to see that prospect already yesterday?)
dont think so, no. Very little can be done at the GP. Might not be impossible, but that something happens as a result of bringing something that isn't verified yet is what we want to avoid the most, so we'd like to do it carefully. There's 20 races, so no way to gamble like that.
No mechanical issue on Friday
Heating problem on Sat, but mechanically no issue
(in order to solve heat problem, any alteration to be made to PU structure and arrangement?) You cannot do that, so we'll work on something/somewhere else
(any compromise on car side?) no compromise. if you compromise on something, you'll stay low. that's no point.
(try new idea?) Right, we'll have to manage it working with McLaren. I think that's the same for any other teams.
(punch hole in the car, for example?) ah we'd like to do something like that certainly, but if you put a hole, air flows better but you lose more in somewhere else instead.
(what's the outlook by being able to finish the race?) Well just one race and one engine. It would be nice if you could open the PU and see everything inside, but it's sealed so can't do. We want to see and check through, but that's the task at Sakura factory, to simulate today's race and examine what was happening with PU. Good first step but we'd like to go forward quicker.
(Current president Ito and next president Hachigo attended GP and were in the garage)
Both incumbent and new presidents understand the situation and have firm commitment, but we can't take things easy and slow. We feel pressure from fans and various people related to us, we want/need result as soon as possible otherwise lose fans.
(9 tokens given) Just accept and go ahead
("drive line" of MGU-K exchanged according to FIA release?) Concerned about friction level etc, so exchanged it under FIA inspection. not that there was particular problem but just to be on safe side
(is it some sort of output axle?) no. something at the base that holds bearings
(So you unlocked the fuel limiter on Jenson's best lap. how about ERS?) nothing tweaked about ERS. The same "save mode" we were running with throughout. We had some fuel left, so went for it.
(it was Mercedes domination. Some claim that FIA should do something about it like ease those regs more or set some sort of restriction etc, your take?)
I dont think so. We have to take the top place on merit, so no point to expect something like that, and quite unlikely to happen anyway. Other teams should have expected such level of competitiveness, but for various reasons they couldnt reach that level. But surely others will recover.
We knew it would be tough race before coming here. In such circumstance, that we could see the flag is the only positive point. As for negatives and regrettables, you can go on listing endlessly. We only have to do it all over again.
(expected better outcome than this from Barcelona results?)
well we thought it was gonna be difficult at the point of friday already. Too many problems unsolved and items unchecked at Barcelona.
The area that we were able to check so far is too narrow, so there's nothing productive about trying something in other unidentified areas at the GP. that's same as abandoning adaptation. So all boils down to lack of time after all.
We can only run with what we've tested and confirmed. This time, we have brought something that is short of toughness against temperature, and it's impossible to tweak and do something at the GP venue. This is such complex system, so even if you tweak one setting, it doesnt tend to go well, it just affects everywhere. The number of data engineers are looking at is enormous. The amount well exceeds the limit human eyes can handle, so.
We estimated temp like sunday's from last year's record, but yesterday was hotter than estimated. 32C was quite hot.
(which component was affected badly the most by heat ?) There was no major issue in MGU-H, altho not completely perfect. But MGU-K was severe. Esp in quali where you use 4MJ of energy at once, heating situation gets severe. We have to improve on that.
Was running engine itself (maybe means ICE) in restricted mode. When the intake air temp is high, we have to apply compromised mapping. If you apply improvised mapping then it would likely damage engine so we dont do that. We couldnt withdraw all from power unit. Lack of preparation so regrettable outcome.
(lowered the rpm during race?) No. Under current reg, there's no point in running it in 15,000rpm, so mechanically it's easier to design in some sense, I guess.
Sobre la primera negrita, por eso "necesitaban" a Button en vez de a Magnussen: un piloto experimentado que sepa gestionar correctamente un coche problemático y, no rompiéndolo/sacándole partido, ayudar a evolucionarlo. Mensaje en la misma línea del motor que salvó Fernando en los test al darse cuenta de que iba mal, por ejemplo.
Sobre lo demás, que la MGU-K se les está sobrecalentando por dónde está y que no pueden tocarla ya (motor homologado), así que tienen que sortear los problemas de otra manera y en ello están. Sin problemas mecánicos y el no pasar de 7ª fue, como ya suponía, por llevar el ERS capado, que como también suponía ocasionó problemas de consumo (aunque se pasaron de pesimistas) y con los frenos. La última vuelta fue a tope con el motor térmico, pero con el ERS capado.
Será muy interesante ver dónde están en Malasia y comparar tiempos con Australia.
Tema tokens, que bueno, que vale.
No van a tocar mucho (normal, ya que aún no saben que áreas son prioritarias).
