China Saturday quotes: Toro Rosso

Jean-Eric Vergne, 18th: "I am not feeling good after that. I'm not really sure what happened this afternoon, but we lacked speed. My lap was not exceptional, but nor was it bad, so we have to try and understand why it was so slow. All we can do is try and have a good afternoon tomorrow and then improve the car for the coming races, because what happened this afternoon was simply bizarre. It's true that I got a good result starting low down the grid in Malaysia, but it would be nice to at least start higher up the order quite soon. I will feel better tomorrow morning and will look forward to seeing what the race might bring."

Laurent Mekies, chief engineer: "Obviously, this was a disappointing qualifying for us and today we clearly lacked the pace we needed to be in the fight. We now have to look at where we lost this performance. We made quite a few changes to the cars from yesterday and during this morning's free practice and we must assess where we did not go in the right direction. So far this weekend, we explored a quite different direction in terms of set-up and maybe it cost something in terms of ultimate pace in qualifying. However, it was a job that needed to be done and we must work out how to improve it for tomorrow. However, I believe the situation for the race is still very much open for us to get a reasonable result, as the gaps are in fact relatively small."
