Coulthard Rues Lack of Track Time

McLaren's David Coulthard endured a troubled start to his United States Grand Prix weekend after being hit by mechanical problems in the second practice session.

"Obviously I lost some track time as I was unable to take part in the second session which is a shame," said the Scot, who failed to set a time in second practice due to an electrical fault.

"All of a sudden at turn eight the car just stopped and there was nothing I could do," added Coulthard, 18th fastest in the opening session.

"Kimi collected quite a bit of data which should help us in making the best tyre choice possible, and we have two practice sessions tomorrow morning before qualifying and the race."

Coulthard's teammate Kimi Raikkonen enjoyed a more positive day and wound up tenth quickest, albeit nearly two seconds off the pace.

"We completed our tyre evaluation programme and will continue working on finding a good set up in tomorrow's two practice sessions," said the Finn. "It can be quite tricky here as you have to find a good balance both for the full throttle part and the in-field section.

"I like this track and enjoyed my first couple of laps familiarising myself with the lay out."
