Trulli suffering from car handling issues

Although the Italian qualified once again in the top 10 in Turkey, he has said he is far from happy with his car.

"It was a reasonable qualifying, even if I am a little bit frustrated," Trulli said. "Recently I cannot push as hard as I want because the car balance does not really correspond with the one I like.

"I am having a lot of troubles with the rear end of the car. It is very unstable and I am not confident at all.

"Maybe I could have gone quicker, but in the end it is the best I can achieve. The car potentially is good but recently I don't really feel very confident."

Trulli says the problem emerged for the first time in the last race and he cannot pinpoint its cause.

"It was the same in Hungary. Recently, I am struggling to push as much as I want.

"I think the car is changing a little bit. We are improving, but I think there are some other areas where we need to probably look more carefully to make sure we are going in the right direction.

"In general, the car is quicker but more difficult for me, and I cannot push as hard as I want."

Trulli believes that Toyota need to get everything right with their car if they are to fight for points in the remaining races of the year.

"We proved that there are some races where we were competitive, and some races where we are a bit less competitive.

"Here (in Turkey) we are reasonably competitive to be in the top ten, but we did not have the advantage over the other men like in Hungary.

"Again, we are in the midfield battle and we need to get the best out of the car if we want to score points.

"The car is still improving. We have a new front wing here, which is definitely a good step forward. But my biggest problem is the rear end under braking."
