Webber breaks down, again

(GMM) Mark Webber in Indianapolis suffered a mechanical breakdown in his Red Bull on Friday afternoon, after he declared that the Austrian squad must up its game in 2007.

"To finish every race and score no points is one thing, but no one is interested in the shopping list of excuses," the Australian, who has yet to score a single point so far this year, is quoted as saying by the Edmonton Sun.

He did admit, however, that his RB3 has shown signs of improving in terms of reliability in recent races.

In Canada, for example, he finished just out of the points in ninth, but his teammate David Coulthard exited with what is becoming a trademark gearbox failure for the team based in Milton Keynes (UK).

Webber said: "When we're on the track we're going pretty well, but we're not always able to run for as long as we'd like."

In the similar STR2 single seater, Toro Rosso's Scott Speed also struck mechanical trouble at Indianapolis as the second 90-minute session of the day played out in hot conditions.
