-Design of oil tank(interior)
-Inside the tank baffels do not pick up oil at high G as they should, causing pressure drop.
-At the circuit only a small fix is possible
-Honda saw problem during film day
-Hasegawa says problem not big, can be fixed

- Massa drove 20 aggressive laps on softs without too much problems
- time gap from medium to soft compound can be up to 2s for some cars, feels like a different car after switch
- tires heat up slower, but not too slowly, able to do 2-3 quali laps as result
- if tires do overheat, they're back to normal within a few corners
- pressures lowered to 22psi front, 18 rear (not sure what was used last year atm) with possible further reduction upon data evaluation by pirelli
- degradation from 20 laps on softs is around 1.5s (down from 4-5s last year)
- Tires now work in a wider temperature operating window (helps ferrari)
- less marbles overall
- a lot less pit stops predicted
- Pirelli say they brought tires as were requested (less degradation), but are willing to go back to more degrading tires in 2018 if requested so
- Massa says dirty air is more noticeable
- Pirelli simulations predict 1:18 by the end of the tests

Question: Can you review the problems you had in the first two days of preseason?
Yusuke HASEGAWA: "It was very unfortunate that we had several problems related to the engine, the first day we had a problem with the oil tank, we could live with that, but we did not want to damage the engine and that's why we decided to change the tank. Which is a fundamental problem, is just a failure of that system, but to access that area we had to dismantle the engine completely and that cost us almost half a day.It was a pity and it was our responsibility.The second day we had some mechanical problems With the engine.We still do not know the cause of the failure, that's why we sent the unit to Japan to investigate it.It was a mechanical failure.

Q: Do I need to redesign the oil tank?
Y: HASEGAWA: "We preferred to modify it to improve performance, but that's fine. During the season we can improve any part of the engine, so we may also change the oil tank, but for now we can live with it."

Q: Have you reduced engine power in these tests, as a precaution?
Y. HASEGAWA: "We have very little time to run, so sometimes we are not going to full power and in some tests we are checking the car or analyzing some data, so you do not need to go full power all the time."

Q: What are your plans for next week?
Y. HASEGAWA: "We would like to introduce the latest version of the engine and test it as soon as possible, every time we have an engine, we change something, so next week we will have another engine."

Q: Will it be Australia's engine?
Y. HASEGAWA: "Yes, we have to check the racing engine here."

Q: In the presentation of the MCL32, you said that the new concept of engine did not pose a risk from the point of view of reliability. Judging by what has been seen on the track, the situation has turned out to be different. What happened?
Y. HASEGAWA: "Nobody could say that we are confident, but we have tried to do our work as well as possible. From the point of view of 'spec' - a power unit - we are not worried, but we do not know what is happening."

Q: New chassis, new engine concept, but in the presentation it seemed like everything was going to be perfect from the start. Do you think they have underestimated the change of 2017?
Y. HASEGAWA: "We have introduced a new system and it is clear that it is not yet mature, so we need more time to prepare and be ready for the first race." I do not think we have underestimated it. And Tuesday are our functional errors, not a bug of the whole. We have to be prepared. "

Q: How does the current situation compare with the situation in 2016? Eric Boullier made a statement in the presentation where he had doubts about his engine.
Y. HASEGAWA: "I think our relationship - with McLaren is strengthening - we connect a lot more, I can not compare it to 2015 because I was not, but we are a team, we act as a team, but we are not a single company. He has his responsibilities and we have to worry about ours. I do not think Eric is unfair. "

Q: How many engines do you have in Barcelona?
Y. HASEGAWA: "We do not say that, but we have enough for training."

Q: The engine homologation date was yesterday.
Y. HASEGAWA: "Yes, I am not sure, and in fact I am very confused with the regulation of the homologation and the tokens, because as we do not have tokens, although we apply some homologation we have the possibility to change the engine. FIA.Each engine has to be homologated, but between the tests and the race you can make improvements because we do not have tokens. "

Q: It would be necessary to plead reliability reasons, I understand.
Y. HASEGAWA: "Yes, I think so. From what I understand, we can improve anywhere."

Q: How do you see the other engines?
Y. HASEGAWA: "I'm not sure I have no idea, because in the tests the teams run in different conditions Fuel, tires ... They can use less rake, more camber ... It's very difficult to know. Is still very strong.When it comes to doing test they always do a great job.There is no doubt. "

Q: Do not you think that Honda is at a disadvantage with Mercedes, because they develop their engine with three teams and you only with one?
Y. HASEGAWA: "That has its pros and cons, because you have many opportunities to test the engine but at the same time you have to allocate your resources to operate with three teams."

Q: He said they wanted to catch Mercedes.
Y. HASEGAWA: "I said that we would like to take Mercedes, but the Mercedes of 2016. It's the goal we set ourselves, we want to catch them, but I do not know how much they will have won this season. Motor will overcome them ".

Q: Alonso was disappointed in his first press conference.
Y. HASEGAWA: "Yes, I am.
