Malaysia Friday quotes: Toyota

"Still, we made it through our programme of work with no problems. We are comfortable with the track and the tyres were also working well. It's difficult to judge true performance after the first race but our goal is to get two cars into the top ten again and hopefully to take more points."

Jarno Trulli - 16th: "Since the beginning of the day I've been struggling so we will have to look into that tonight. The track was short of grip early on and I found myself sliding with all four wheels. The car has been inconsistent and it has not responded to the set-up changes we've made.

"And while the track improved I actually got worse with the same set-up. So something strange is happening and now we need to investigate why. Still, I like this track and I have always performed pretty well here. The weather is changeable and our forecasts say we may yet see some thunderstorms during the weekend."

Dieter Gass - Chief Engineer Race and Test: "We got a lot done in the two sessions so that was a productive day. For both cars to run trouble-free was good, especially in the hot conditions that we have here. Even though we tested here last week we still had a lot of things to do and we went through our programme quite well.

"But you wouldn't have known there had been a test last week from the track which was as short of grip as usual on a Friday here. Both cars were sliding a lot and it was not easy to find a balance in these conditions. But given how many laps we have completed, we have a lot of data to look at tonight to see what changes we can make to improve our cars further for tomorrow.

"In Australia there was quite a big difference between the two tyres but here there is a far smaller gap and both tyres are well suited to the circuit. That means we will have to work out how best to use them over the weekend."
