Brazilian GP practice quotes: Marussia

Max Chilton - 21t: "It is an important weekend for us so with Rodolfo having taken over my car this morning, I spent that session focusing on the feedback being given to the engineers by him and Jules in light of the track conditions. This afternoon I was finally able to sample the track for the first time and it's a great circuit but pretty challenging in the wet. We've made good progress in tricky conditions and worked through a few scenarios for what could be changeable weather over the next couple of days, although we are hoping we have seen the worst of the rain. Generally I'm really happy with the pace."

Rodolfo Gonzalez - 22nd: "Today was my ninth Free Practice 1 session at what is the closest event to my home race, so it was nice to have a clean session, although it was hampered by the rain. We did achieve 19 laps though and a lot of our planned wet weather scenario programme, so the information will be useful for the rest of the weekend. I wish the Team all the best of luck now for the right outcome on Sunday."

John Booth, Team Principal: "We came to this event with no significant developments for Friday, however we were geared up to do a comprehensive assessment of the 2014 tyres. Unfortunately this program had to be put to one side due to the weather but that said, we have still done some good testing today. The wet conditions have been an area where we have never been 100% happy with car balance and performance and it was good today to spend significant time working on this. It appears we have made some progress in the afternoon session and it was good to also get both drivers to feel the cross over from the extreme tyre, which will be good experience if it is wet for qualifying or the race - or both! It looks like the weather is still unpredictable for the next two days, however we can be confident that we have conducted some good preparation for that situation and we hope to get some dry running in FP3 to see how the car behaves more generally at this circuit."
