Trulli says car balance needs work

The Italian driver finished as third fastest in the afternoon, just three tenths of a second behind the pace-setting Williams of Nico Rosberg.

Trulli, however, said he was not completely happy with his car's balance and that, despite its pace, the TF109 was not easy to drive.

"It was a tough day because we covered quite a few laps and had a lot of things to work on," said Trulli. "In general we have worked really hard to understand the tyres and find the right set-up, which is not easy.

"I am still not completely happy with the car balance and, even though when you look at the timing sheets things look pretty good for us, the car isn't completely comfortable to drive.

"Now we have to work on improving the set-up and the balance for tomorrow when it is most important.

"Anyway, I have to say it's great to be back at a Grand Prix because I love being behind the wheel with the atmosphere and excitement of a race weekend; this is what I live for."

Team-mate Timo Glock completed a good start to the weekend for Toyota after posting the sixth fastest time.

The German admitted he also had some problems with his car's handling, but was pleased with his day's work nonetheless.

"In the end I am satisfied with our day but I have to say the first session went better than the second session for me," he said.

"In the first session I had a good feeling from the car and things were running well but then later on I suddenly had a few problems because the car was a bit nervous and didn't feel as stable on the long runs.

"The behaviour of the car seemed to change between the sessions so we have to look at the data to understand why that happened. So we still have some work to do but that is the purpose of practice and we will work hard on the car set-up before qualifying tomorrow."
