McLaren has become the latest team to reveal details about the launch of its 2012 car.
Direct rivals Red Bull and Ferrari have already announced that their next single seaters will be ready for the start of the opening test of the 2012 pre-season.
"The MP4-27 will break cover on Wednesday February 1 2012," Woking based McLaren said on Monday.
The Mercedes powered team said the launch location will be announced "after the new year".
"The MP4-27 will test for the first time at Jerez on February 7-9," McLaren added.
Mercedes’ new car, the W02, will not be tested until the second test, set to take place in Barcelona two weeks after the Jerez session.
