Toyota to change Trulli's engine

The engine change will not hit Trulli, however, as he failed to even set a time in the first session after his engine blew up during the opening minutes of the session.

Trulli, who has yet to score a point in a luckless season, will start last of all after limping down the pitlane with a cloud of smoke coming from his car's engine.

"Unfortunately I could not even record a time in qualifying today because I had an engine problem on my first flying lap," said Trulli. "I just noticed smoke coming out of the back and that was the end of my afternoon's work.

"It means I will be starting at the back of the grid tomorrow, which is a particular pity because our new TF106B was going well here, as it did in Monaco.

"Yesterday we were competitive and we were confident after this morning because we didn't use any new tyres. It will be a very difficult race tomorrow because it's practically impossible to overtake around here.

"Still, I will stay focused, push as hard as I can and just keep hoping my fortunes will soon turn around."

Ralf Schumacher enjoyed a better day after finishing in seventh position.

"We can be very satisfied with what we achieved today. We expected to be somewhere between 6th and 10th so we managed to secure a good position," said Schumacher.

"The car was really good, too. I struggled for grip yesterday and also this morning, as with many others here.

"It wasn't perfect for me in the first two sessions but as qualifying went on the guys got it right so thanks to them. My last run was much better and we had a lot of fuel on board so we're pretty pleased.

"As in many other circuits in Formula One it is a bit difficult to overtake here but we are confident about our strategy so we are looking forward to tomorrow."
