Whitmarsh: no complacency at McLaren

Lewis Hamilton took McLaren's third consecutive victory in Indianapolis on Sunday, as Ferrari found themselves unable to find the race-winning pace that they had at the start of the season.

And McLaren F1 CEO Martin Whitmarsh says his team are confident they have got plenty more aerodynamic developments to put on their MP4-22 to maintain their edge.

"Aerodynamics are still the determining factor," said Whitmarsh. "We started out at the beginning of the year with a target of 0.15s per race improvement and we increased that to 0.2s per race. Now we're doing better than that. And looking ahead.

"We've got high confidence in the engineering processes - we see improvements straight away on the stopwatch. We've got a reasonably good step forward in the pipeline for France and, looking at the development system, we've got some more things coming through."

Ferrari are planning to test revisions to their F2007 at Silverstone next week, which is likely to include not only car improvements but changes to the way the car is set up. The Italian outfit believe that their main weakness remains the qualifying pace of the car.

Whitmarsh thinks that the development battle between McLaren and Ferrari will be won by minor rates of improvements, rather than one outfit finding a big leap forward.

"This year more than ever, it's all about a broad number of very minor changes," he said. "Anyone who studies the car closely, you'll typically see 10 or 20 visible changes - let alone the ones that aren't visible - that are packages going onto the car.

"We're really on a very micro-level managing airflow around the car. And we've got a great team of young engineers with the bit between their teeth, charging along.

"But they're not complacent because Ferrari is a good competition and want to win this championship too and they will keep the pressure on us."
