McLaren will buck the trend of its closest rivals by not revealing its 2011 car until after the Valencia test.

6951 - McLaren unlikely to use 2011 car for Valencia test

While fellow 2010 title contenders Red Bull and Ferrari plan to kick off the four-test pre-season period with new cars, McLaren has announced that the MP4-26 will not be unveiled until February 4.

That is the day after the Valencia group test ends, making it likely that McLaren will commence its winter programme with an interim version of the 2010 chassis before the new car debuts at Jerez.

McLaren said the 2011 launch will take place in Berlin but gave no further details.
