Trulli 'very' confident for the race

Having set the fastest time in qualifying during Q2 - 1m44.503s - Trulli said that it was his consistent pace during high-fuel running throughout the weekend that has given him confidence ahead of the race.

"I am very confident for tomorrow," said Trulli, who starts alongside a potentially light-fuelled Giancarlo Fisichella, who is on pole.

"I have been running most of the weekend on heavy fuel and being second on our fuel load will mean a good race tomorrow.

"We came here and thought we would be strong, in Q2 we were top and in Q3 we looked good.

"I have to thank team and I dedicate this to all my mechanics who are going through a difficult moment and sometimes it is hard to understand what is going on."

Toyota struggled throughout the European Grand Prix weekend, and Trulli admitted that he was a loss to explain the team's upturn in form at Spa.

"It is a mystery," he said. "We haven't done anything on car since the last race, yet we have been competitive all weekend.

"It is great for the team, for the engineers, my mechanics. We don't understand sometimes why we struggle so much or why we were so quick like today

"We didn't really get a special update here - just the normal downforce and wing level changes for this kind of circuit.

"We spent most of the time basically balancing the car between the high-speed section and mid-speed section," he added. "We made a change on the car set-up this morning so I had better engine and better traction.

"But it is a good question, which none of us can answer, especially when things go wrong. When things go right we know we have a good car, we have had it since the beginning of the season. But we don't know why sometimes we are very bad, sometimes it changes from session to session."
