Team principals: Ross Brawn (Honda), Norbert Haug (Mercedes), John Howett (Toyota), Frank Williams (Williams)

Q:

Ross, Rubens Barrichello is celebrating his 257th Grand Prix. You have worked with him quite a lot with Ferrari and now Honda. How much has he changed? Give us a little appraisal of his current state.

Ross Brawn:,/B>

He has not changed at all. But what is great, not only about the achievement of 257 races, is the fact that he is still as strong and as competitive for many more. When Riccardo Patrese reached the record he was retiring, but there are no signs of Rubens needing or wanting to retire in the future.

Q:

Do you think he is still learning?

RB:

I think every driver keeps learning as do the engineers, technicians and all the other people involved. There is always something to learn in F1.

Q:

We saw Jenson Button in the points in Barcelona. Is that the product of new bits and pieces coming through but is it also perhaps a development of the Brawn effect?

RB:

There is a good programme of development with the team and with the car. I think there is some benefit from the changes and the progress we have made with the car. From where we were with the car in winter testing I think we can be quite pleased where we are now. What I want to do in the future is start the winter testing with something a lot stronger than we had this past winter. On your second point I hope I have been able to give the team some more confidence in doing the right things. They are all capable of doing a very good job. I think sometimes it just helps to have a reference point with someone who has been fortunate enough to win races and championships and who can say 'guys you are not that far off, let's just work hard and focus on the important things and we can do it.' That's the thing I have tried to bring to the team.

Q:

As well as that, how much has it been a case of putting the right people in the right places?

RB:

There is always that in every team. Every successful team is a combination of a lot of very good people, all highly talented people and sometimes it is a question of helping them see each other's needs as well as their own and getting the whole group to work together. You will only succeed as a group. You will not succeed any other way.

Q:

John, Timo Glock is somebody at the other end of the scale than Rubens, having his first season in F1. How do you feel he is developing?

John Howett:

Very well. He had a good day today and his confidence is growing. We are very happy. He is a cohesive part of the team and he has certainly shown at times that he has the capability to do a very strong performance. We are looking forward in the next few grands prix to really seeing the full potential.

Q:

He started off particularly well but the qualifying seems to have dropped off a bit.

JH:

I think only the last race in Barcelona. I think he had a very strong race in Barcelona, but he didn't manage really to get a strong lap that he had shown in the first three that he could actually put in. It is part of the growing experience in F1 and getting used to the tyres, getting used to setting up the car for both the race and qualifying. We are very happy where he is at the moment and we expect a lot more performance in the next two to three races.

Q:

We have seen Jarno Trulli in the Top 10 quite a lot in the last few years, but not necessarily confirming that with points finishes. But in three out of the four races this year he has been in the points. What has changed?

JH:

I think he just has confidence in the car. He is really sparkling if I can say that this year. From the Bahrain test he had confidence in the car and he is really delivering in qualifying and I think he has an extremely strong race pace.

Q:

Frank, a word about Kazuki Nakajima - twice in the points. How do you feel he has got on?

Frank Williams:,/B>

Well, he is very young and very sincere and earnest. He works hard at the track and away from the track and spends more time on his fitness than even Nico Rosberg does. I think if his car is good enough he will be as good as the car and he will do well.

Q:

Nico seems to have been in and out of the top ten. Is the problem with the car?

FW:

We have seen him spend quite a bit of time out of the Top 10 until the time it really matters. I don't know how many times we have qualified out of the Top 10, but I don't think it is more than once or twice this year. But it doesn't seem to bother him and he always seems to accelerate from 15th to 10th at the first corner and 10th to 8th by the second. It is great to watch.

Q:

How do you feel you are getting on with the battle in the midfield as that really is a major battle with everybody?

FW:

It is. It is unpredictable every time. You could be at the top of it or the bottom of it only covered by two or three-tenths-of-a-second at two or three circuits. It is not the place to be.

Q:

But knowing you are a racer it must be very exciting to see where you are coming out of it.

FW:

We worry about the amount of points we collect at the end of every year or have collected. That makes such a difference to the money, of course, and everyone's morale and the sponsors.

Q:

Norbert, we saw Heikki Kovalainen have the accident at the Spanish Grand Prix. You have seen a lot of drivers coming back from big accidents in the past. How do you feel he has come out of it?

Norbert Haug:

I think he is fine and that for us, and I think for the F1 community, is the best message of today. He came and settled into the car and just continued like he drove the car before - very focussed. He had a smile on his face this morning which was very positive. He passed the test yesterday in a very good manner, so we are all very pleased that he is back and can do a very good job.

Q:

From an engine supplier's point of view how much development are you still able to do?

NH:

Very, very limited after the start of the season really - just some stuff around the engine and the outside, but not the inside. As the expression says, it is basically frozen.

Q:

That was not an expression you liked.

NH:

Not at the beginning, that's right, probably there could be a better one. But in the meantime everybody knows what we want to describe by saying that.

Q:

Do you think the disparity has grown in terms of the power of the engines?

NH:

I think it is difficult to judge really as it is the whole package at the end of the day. If you look at the data and the top speeds and lap times, if anything, it has closed together. I think it is a really, really intense battle - much more so than in the past. F1 was never easy but it is really unpredictable and if we make a mistake we may end up 10th on the grid or whatever. It is really closed together and if you look at the fastest race laps of the recent races, even in Barcelona which is a very challenging track, I think the whole pack came together in a very impressive way. It is the end of a period with a comparable set of rules and that's always the case, but I think F1 has never been more challenging as it is now and you can name a lot of teams that are capable and invest a lot of money and have good people. But it is a very intense fight.

Q:

To all of you. Your feelings about the loss of the Super Aguri team.

RB:

I think it is always a great shame to lose any team from F1, we cannot really afford to be losing teams. I think they showed a lot of character and a lot effort in the past couple of years but circumstances prevailed and they were not able to carry on. But it is a shame that they were not able to find the funding to continue.

JH:

Very sad to lose a team, but I would say it is as competitive off the track as it is on the track to maintain a commercial environment and a strong team. I think in the end we are in the premium level of motor sport in the world and we have to compete at all levels - both on and off the track.

FW:

I cannot really improve on what's been said by the two honourable gentlemen behind. They have said it all really. It is a shame.

NH:

It is a shame. We all know Aguri, he was driving in F1. He is a particularly nice guy. I think he worked very hard, but the fact that more teams have left F1 than are currently staying in F1 just describes the fact how difficult it is to continue on that basis. In that case it is particularly sad because they have been nice guys, good drivers, very committed. The beginning looked very promising and they had quite a good set-up and made it into F1. At the very last moment I think they went flat out, had good support from Japan and from various people and even more, so it is a shame that they need to quit right now.
