Singapore GP Friday quotes: Toro Rosso

Jean-Eric Vergne - 18th: "This is definitely the hardest new circuit I have come across so far this season, with so many corners and the fact it's really hot. I really enjoyed this whole experience of racing on a street circuit at night, but at first I was making a lot of mistakes on what is a very long lap. But I am getting used to it, I brought the car back in one piece and I know I will improve tomorrow. Overall, the car did not feel too bad, so I think if we can improve it a bit and I learn my way round a bit better, there should be more to come for the rest of the weekend."

Laurent Mekies (Chief Engineer): "A very different challenge to our last race in Monza, the lowest downforce track of the year and the Singapore layout was always going to be more challenging for us. We had a full programme to get through today, which required doing a lot of laps, partly to allow our drivers, especially Jean-Eric on his first visit here, to get into the rhythm of this difficult circuit. We also needed to find the best compromise in terms of car balance on short and long runs. We still have plenty of work to do, because although there were moments today when our performance was reasonable, we were not able to reproduce that consistently. We have to understand the reasons for that so we can move forward. On the positive side, both cars ran reliably and neither of our guys made any mistakes and we know how tough this track can be for the drivers. We evaluated a couple of new elements on the car and we have to look at all the data with the aim of upping our overall performance, especially in race trim for Sunday."
