Whitmarsh succeeded Ron Dennis as team principal ahead of the 2009 season, since when the team has failed to win the drivers' or the constructors' championship.
But Whitmarsh, who has been a key player at McLaren since joining the team in 1989, insists that he has not considered stepping down and is resolved to oversee a turnaround in the team's fortunes.

He is also certain that the possibility of him being removed has not been looked at at board level.
"No, I don't believe it is being considered at board level at the moment as far as I know," he said.
"I believe in the team, I believe that we are going to power through this so no, I am not considering anything other than getting this team back to where it belongs."
Whitmarsh pointed to the difficult times McLaren has weathered in the past as part of the reasoning for not considering such drastic action.
He added that he is continues to enjoy the job.
"I have been around the sport for a long time," he said.
"I have sat here [and answered questions] in difficult moments, dark moments and I've sat here in good moments as well.
"I enjoy going motor-racing and I enjoy going motor-racing to win so I don't like it when you come with a car that is not good enough to win.
"I have been around when we have won more than 100 races and I am sure that we are going to win more races. We are going to work hard to do that this year."
