Singapore Friday quotes: Toyota

"But that didn't affect our programme and overall we got through a lot of work today, so it was successful in that sense. So far I am not totally happy with the car and we have quite a lot to improve but I will sit down with my engineers and I'm sure we will make progress before qualifying. We will see how it goes tomorrow."

Jarno Trulli - 19th: "We have been improving gradually throughout the two sessions. We are trying to find the right set-up and we have changed quite a lot on the car. It is really bumpy out there and I struggled a little bit with driving at night because there are some dark spots which make it a bit harder than normal.

"To be honest the circuit is not particularly challenging for a driver because it is mainly made up of 90° corners but I hope it will be a good spectacle for the fans. In first practice unfortunately I had a spin at the last corner and I wanted to move off the racing line as safely as possible, so I decided to go down the pit lane.

"I took the quickest and safest option available to me and the other cars. I have been penalised and I accept that but I know I did the safest thing for me and the other drivers - it is one of the quickest corners on the track and you don't want to have a crash there."

Dieter Gass, Chief Engineer Race and Test: "We should say congratulations to the organisers who have prepared a fantastic facility here. I think it is going to be a very exciting race; it is the first time Formula 1 will race in the night and all the ingredients are there for an interesting weekend. In general the track is a bit bumpier than we expected so that is something we have to adapt to and that situation is the same for everybody.

"In terms of running at night, we had no real issues, although the drivers were commenting that there were some areas which were a bit darker than expected, but in general it was fine. Today the track was evolving throughout, as you would expect with a new street circuit like this. Obviously it was very dirty in the beginning but then it rubbered in. We still have some work to do on the set-ups before qualifying, but we got through a lot of work today so we have plenty of data to study."
