Adrian, in terms of next year, when do you need to know the engine choice? As far as the press is concerned, they're not awfully sure which engine you're going to be running next year. When do you need to know?
Adrian Newey: Luckily with the current V8 engines now, the installation of engines is fairly similar so we've been able to wait this long. We can wait for a little bit longer but we will need to know soon on the final decision.

So Christian, when are you going to tell him?
Christian Horner: Obviously a lot's been said and discussed about engines and we at present have a contract with Ferrari for 2007 that we entered into in May of last year. Obviously there's another team that Red Bull has an interest in now, an Italian team, and obviously it would make sense for that team, with an Italian driver and an Italian engine, that there's a natural synergy there, but that requires consensus with all parties involved and we will no doubt reach a conclusion on that in the very near future.

That suggests that you have an alternative for Red Bull Racing.
CH: Basically, as I say, we entered into a two year agreement with Ferrari. If that agreement has the possibility of being assigned, then it's something that obviously we will investigate that would potentially pave the way to put a different engine in the back of a Red Bull Racing car next year.

Christian, in terms of drivers, it's interesting that you've opted for more experienced drivers whereas a company like Red Bull might have gone for youth. And we've seen some remarkable younger drivers coming through – being very quick – as we saw today with Sebastian Vettel. What was the policy behind that?
CH: Well, basically the Red Bull Junior programme is working well, it's producing good drivers: Scott Speed, Vitantonio Liuzzi, Sebastian Vettel are all products of that. We looked at this scenario very closely and when a driver of Mark's experience and calibre… a window of opportunity presented itself, it made sense for us to work with experience in 2007 and it wasn't a difficult choice to make in the end. The youngsters are gathering experience and we felt that there wasn't anybody on the scheme to make that step at this point in time and the choice with Mark was a very easy and very natural one to make in the end.

Adrian, I know you've been working on the design of next year's car for some time. Has it been difficult with these occasional regulation changes slightly moving the goal posts, or has it been quite simple?
AN: There aren't many changes to the regulations for next year. There's a change to the rear crash structure which has been known for some time. The one that's had a bit of greyness to it has been the anti-intrusion panel that has to go on the side of the chassis but it's really not been a difficult year as far as regulation changes go and as I say, as far as the engine goes, I think the specification of the V8 engines by regulation now means that the installation of any given V8 engine isn't that different to another one.

And has the development of the current car pretty much finished or are you still developing the current car?
AN: No, we took the policy decision a little while ago to freeze development on the current car so that we can channel all our efforts into next year's car.

Norbert, has the engine freezing – I know you don't like the expression – has it been pretty much resolved now for next year and the future?
Norbert Haug: I think there are still discussions in place and probably over the course of the weekend, but it's difficult to go into details. You know what was published by the FIA, that is the status currently, but obviously we have some other views.

So it could be decided this weekend?
NH: No, that's not what I'm saying, I've said there are discussions, there will be discussions in place and I just hope that we can find a solution for the next couple of years. We worked hard for it.

Talking of development this season, presumably it's still continuing on the engine front, as inevitably it would?
NH: Absolutely, yes. It does. We are doing it step by step and everybody is working flat out and Ron will describe in more detail but certainly on the chassis as well.

In terms of ownership of the team, it has been suggested that Mercedes is interested in taking more share-holding in McLaren. What are the advantages for Mercedes in doing that?
NH: I think that is a very theoretical issue at the end of the day. Whatever we do in the future is to strengthen the team. I think we work together in a very good way and I have to say we make big steps again, between engine and chassis. I find it very very positive, how the co-operation goes on, and whatever we should do, and I stress should, has just that background. Can we be even stronger? I think we were not quite luck this year. We have had some chances to win, but we did not use them but we know what we're talking about and I think we know how to raise our game further. The potential is there and we certainly will use it. Whatever we do, whatever the decisions are, and there is no imminent decision, will be taken with the background to strengthen the team even further.
