China Friday quotes: Toro Rosso

"Actually I was quite surprised to see how well they are holding up and they definitely have more than one lap in them. I'm not saying we'll run them for 30 laps, but it's much better than expected. We can definitely see that the small updates we have on the car since Malaysia are working well."

Sebastien Buemi - 15th: "It's my first time here and beforehand I spent a lot of time on the Red Bull Technology Simulator and it was definitely a big help and I plan to use it more in the future. It is difficult to quantify, but for sure it helps.

"I had a technical problem in the morning which cost me some time, but everything was back to normal this afternoon and we were able to make a step forward. We look more competitive than in Malaysia and we are definitely improving. I didn't get a perfect lap today, so I think I can do a lot better tomorrow. I like the track; it's very big, very new, very everything!"
