A question to all of you, the 2009 car. Can you tell us how important you feel that car is going to be? How advanced you are already and what are the significant points about it?
Pat Symonds: I am not quite sure what you mean by important. Every car is important every year. It is very interesting as it's the first big change we have had for a long while. I am sure everyone knows it is a big change to the aerodynamics and it's a replacement of grooved tyres with slick tyres which in turn means using different weight distributions and all sorts of things. It is a very interesting challenge. It's, I guess, quite a difficult one. We do need to start on it early and we have started on it early. I am sure we are all the same. Obviously we have had models in the wind tunnel even though we are still discussing the finer details of the aerodynamic rules. It is a good project. I hope and believe that it will improve overtaking which is one of the main reasons for kicking it all off, so let's see what we get.

Sam Michael: I think the rules are quite different, especially aerodynamically for a start and getting rid of all of the majority of the appendages on the car – barge-boards, flip-ups, chimney. Physically from the outside the cars are going to look quite different with a very wide front wing and narrow rear wing. The target which came from the TWG which was to improve overtaking and it remains to be seen how much impact we will have on that. It will definitely have some impact and that will be good. That combined with big tyres and a big increase in tyre grip. As Pat said everyone has started their wind tunnel programmes and also CFD programmes. It is quite a difficult balance this year to balance how much you develop the current car, the 2008 car, and how much you develop the 09. Normally even if you have reasonable rule changes from one year to another they are not as fundamental as this one, so you can continue developing the car right to the last race and the bits you develop on that car can be carried over to next year's car but it almost doesn't apply now. If you are still developing you car at the last race it will get thrown in the bin at the end of this season. It is probably harder for the three teams fighting for the championship, but it is equally hard for the teams that are fighting I would say to be the best of the rest at the moment, that fourth spot. There are three or four teams that are capable of running in that position and it is going to increase the pressure on them as well. We are all going to be doing that balancing act throughout the season.

Adrian Newey: It's a new challenge for the engineers which is great. I must admit my reservations. The biggest problem is a question of resource. As Sam said we are all in a position where we are all for our various different reasons desperately trying to improve this year's car but at the same time we are conscious that you have got to start researching a very different car for next year. If you had limitless resources you would divide everything in two, you would go to four wind tunnels as I believe Honda are using at the moment and off you go and start research. If you don't have those resources then it is a much more difficult juggling act. The last really big regulation change we had was 2004-05 when the front wing was lifted considerably. The great thing as far as I was concerned about that rule was it didn't really come out until the beginning of July by which time we had all done the bulk of our development for that year. We could all go off starting from the same place and do our best in the time available. This one is very different. We have known about it since November-December. As Pat says rules are still subtly changing but we have known the essence of it for a long time, so it really is a question of how we divide resources.

Willy Rampf: For us it is a very demanding rule change and quite different to the last years. In the last year we had always a fluent transition from the one car to the next one as the regulations changes were fairly small. This is completely different now because we have to run the development project parallel which is not so easy because we have the one wind tunnel. It means we have to divide the capacity of one wind tunnel and currently we are doing a lot of work on CFD to sort out the basic requirements and then go into the wind tunnel.

Aldo Costa: Again, it is very interesting but it will be very difficult to measure change in aerodynamic. We have also got the KERS and the tyres. This will require a rethink of all of the mass redistribution of the car. It will mean a lot of studies – not only aero study, but also a lot of research in the KERS area, a lot of research in the basic car layout, so it is very demanding, so strategic choices during this year will be to be focussed more on this year's car or vice-versa. It will be very difficult to do.

Another question to you all. Can you give us some idea of the modifications that you have made since the last grand prix? Pat, I think yours is the most obvious.
PS: Aerodynamic and suspension. A lot of aerodynamic changes and when you say most obvious, yes, it probably is. You will see a very different engine cover, some subtleties around the barge-board and the front brake areas. Changes to suspension, quite a lot of things. I think this becomes a general trend these days. Most teams tend to cover the first three races with only minor changes, the sort of things we can get done and fit to the cars without extensive testing because we cannot really do that testing while we are out of Europe. Coming back to Europe there is a big back-log of things we are trying to get on the car. We had quite a good test here the other week although one day was spoiled by the weather, the rest of it we managed to get a lot of stuff done, so that's reflected on the cars here.

Do you feel that you have made a step forward and that you have got closer to the opposition?
PS: It's difficult to say. The test was, of course, perhaps a little bit more difficult than usual and it is always difficult to see where you are in a test. It was a bit more difficult than usual because people were running different levels of downforce and of course the 2009 tyres at times, so it wasn't always easy to see how people were approaching things. Again, if you look at today, the mere fact we have been testing here means that the Friday programme is a little bit different to usual. I think we have made a little bit of a gain relative to most of our competitors – not all of them but most of them – but the proof of the pudding will be know by Sunday night I guess.
