Liuzzi laments lack of downforce

The Toro Rosso driver said his car just lacked pace and downforce after qualifying in 18th position.

"We are just too slow at the moment and the car is missing a lot of downforce," said Liuzzi.

"Even if I have said it so often, this is partly due to the fact we need to do more testing to understand the car better. The car balance was good but track conditions had changed a lot since yesterday.

"Last week, Malaysia was more of a driver circuit where I could try and make a bit of difference, but here it is just down to the car."

American teammate Scott Speed will start tomorrow's race from 19th place after complaining about the handling of his car's rear end.

"This afternoon was the first time today I ran the "Option" tyre and it felt quite a bit different," said Speed. "In general, it felt as though the car was more unstable under braking.

"The car balance was much better than yesterday, because the gap to Tonio has closed and I am running a similar pace to him, while yesterday he was quite a bit quicker than me.

"So we have managed to get the balance right but for whatever reason I was not happy with the rear of the car. This was not what I had expected."
