Toyota: We have more work to do

Trulli's day was made more difficult by an electrical issue in the first 90 minute session, but the Italian recovered to the set the ninth fastest time in the afternoon.

"It was a bit of a difficult day for me," said the Tuscan driver. "I lost part of the morning session with a technical problem so I lost a lot of running when the track was dry and then in the afternoon unfortunately I couldn't do much because the session was hampered by the poor weather.

"So in the end there is very little we have learned from today's sessions.

"I hope this will be a good weekend for us but of course it depends on how the car suits the track and there are many other variables, such as the weather and the track temperature, which do affect things. I hope we can keep up the momentum from recent races and be strong again."

On-form teammate Timo Glock could only manage 14th fastest time in the wet/dry afternoon session, but did at least crack into the top ten in the morning.

"Today was pretty tricky in general, especially with the weather which didn't make it easy in the afternoon," he said. "We still have to work on the car because I am not completely happy with the set-up at the moment.

"The cold conditions didn't help us. We made a little step forward on the last run but there is still improvement to be made. We have to wait and see how it goes tomorrow."
