Sep.12 (GMM) Sebastian Vettel is worried about the performance of his Renault engine ahead of the Italian grand prix.
The young German was between 2 and 3 kph slower than his teammate Mark Webber in a straight line on Saturday; a handicap described by the Australian as "peanuts".But Vettel, having qualified at Monza lower than ever in 2010, said: "Overtaking is going to be very difficult."Team consultant Helmut Marko told Bild newspaper: "We do not have a super engine."Vettel's extra speed deficit at Monza is a mystery."It was a new engine," Vettel confirmed, "but it seems not to be as good as we expected."He is not sure what he is expecting from the Monza race."It's hard to tell -- better than sixth place, I hope," said the German. "And it's better that it is Fernando and not Lewis on pole position."He vowed to take a normal approach to the start of the race."I'm not sure; either I act like a bowling ball and knock everyone out of the way as all the experts expect me to do now, or I will approach the race as usual," he answered sarcastically.
