Tonio, a very good performance in Canada. Has the change of chassis made a huge amount of difference to you?
Vitantonio Liuzzi: Quite a bit. I think we realised what happened in races like Barcelona and Turkey where we had a lot of problems and they were two different ones. In Barcelona it was clearer that it could have been the chassis but in Turkey we realised it was an aero problem. We just realised after the race, so we changed anyway to start again from zero to the point where we were at the beginning of the season. It was definitely a good choice as we started strongly from Friday morning in Canada. We still have to wait for a proper circuit, maybe like Silverstone, to be 100 per cent that everything is back in business but we are definitely more confident that we are more in the ball park where we should be.

Was there damage to the chassis? What do you think was the problem with the previous one?
TL: No, basically we changed the first chassis not because of a damage problem, but with a problem on the straight. We were scrubbing speed on the straight for some reason. We couldn't understand why and that's why we changed to the new chassis. With the new one we had a handling problem. We tried many different things and in Barcelona we were just where we were all week and we couldn't understand why. And Turkey was an aero related problem that was adding to the other chassis issue we had, so we still couldn't find exactly the right problem, so we just went back to the beginning where we started in a strong position at the beginning of the season. That's all.

Can Force India maintain the pace of development?
TL: I think the team showed last year that our development curve was really high, maybe one of the best teams in development during 2009. I think they did a really great job and we are still improving. We are working... (becomes inaudible) and we have got a big programme of development, so we are pushing hard. We still believe we can fight to catch Renault in the championship. We will try hard until the end. We have to look at all the others and how they are doing as the other teams are not sleeping, but we are not giving up.

Vitaly, you are almost a local driver here and at least you have experience of the circuit as well. Do you feel that this is a home race for you given that you don't have a proper home race?
Vitaly Petrov: No, of course my home is in Russia, but this is almost my second home as I was living here for three years as my team was here for three years, so I moved here but now my team is Renault, so I will move to England. I know the circuit quite well as all morning I was running around this circuit.

You are just about to come up to complete your first half of the season. How do you think it has gone for you, a personal self-assessment as it were.
VP: Really I don't like to speak about this. I don't like to say something about myself, what was good. It was quite good results, quite bad races also. Canada was not so good. I think I am still learning. I have still a lot of races until the end of the year. I hope I will improve. I am pretty happy.

Do you measure yourself against Robert Kubica? How do you get on with him and are you getting closer to his performances?
VP: Of course I am getting closer. Each weekend I try to be closer to him. But anyway I do my job. I try not to focus on him. I just try to focus on myself, my driving, to improve the car with the engineers and try to do good results, for example, like Turkey. Except one touch, but it was okay.

To the front row, it is to some extent a second home race to you guys. What does it mean to you individually?
Jaime Alguersuari: It is always good to drive in Spain. In Barcelona it was a good environment. It is always nice to drive in your home race. For me that was Barcelona and this race is the second race I did last year after my debut and it is the first race this year that I drove last year, so it is going to be nice. Let's see how we get on during the weekend. I am really excited.

Fernando Alonso: It is always good racing in your home country. Hopefully we will put on a good show for all the people here. As Jaime said with Barcelona and Valencia we are lucky to have these two opportunities in front of our people, so as I said hopefully we will put on a good show for them.

Pedro de la Rosa: For me it is a second opportunity in my home country in front of the Spanish fans. In Barcelona I didn't manage to finish and here I hope we will and hopefully fight for the points as well. A second opportunity and hopefully it won't slip through my fingers.

An interesting point is that you haven't raced here before and your team-mate also hasn't raced, whereas with Toro Rosso both of their drivers have been here before. What does that mean to you? How easy is it to learn the circuit?
PdlR: Well, I think it will not be a problem. We have on Friday two hour-and-a-half sessions and it is more than enough to learn a track. It won't compromise the weekend, especially knowing the first session normally is very dirty here, so you cannot really learn much on set-up, so we don't compromise the track time in changing the car. We will drive the first session, learn the track and get ready for the second one which is always more representative of the track for the Saturday and Sunday. So no issues. Just learn a new track which is always a great pleasure.
