Chinese GP practice quotes: Caterham

Giedo van der Garde - 21st/20th: "Both practice sessions for me were ok but we've had issues all day that have held us back a bit. This morning we had a KERS issue that meant we were running without KERS for the whole session, and that obviously didn't help, and then in the afternoon I overcooked it going into turn one on one of the medium sets and that meant we had to cut short the FP2 plan so we didn't use up another set of tyres. Despite that we have a lot of good data on the medium tyres from both sessions and the performance run on the softs went ok. Degradation levels are going to be big here, particularly on the softs which had pretty much gone by the end of the long run we did on them, so we'll have to look closely at how we deal with that on Sunday.

"We know this isn't going to be a particularly easy weekend for us but I still think we can fight tomorrow and on Sunday. The atmosphere in the team is good and if we can repeat the sort of race performance we had on Sunday in Malaysia we'll be ok."

Ma Qing Hua - 22nd: "It was a very proud moment for me to be the first Chinese driver to take part in an F1 session in my home country, but to be honest I was focusing on doing my job and I'm pleased with how it went. I want to thane Caterham for this chance and for helping make me so comfortable in the car and all weekend.

"We did 20 laps and my times kept coming down as I was more and more comfortable with the car. It felt like we had a slight issue towards the end of the session that cut the fourth run short but after a few checks it looked like a sensor problem so I was able to finish the session with a car that felt good with the final changes we made.

"I've learnt a lot this weekend already and that was the main thing in FP1 - make sure I completed the runplan and don't push too hard so I could learn as much as possible. Cyril Abiteboul told me he was happy with my performance at the end of the session so I'm really pleased with how it went."
