Mercedes have confirmed that they will take the covers off their new challenger on February 21 in Barcelona.
The Brackley squad will be the last of the front-runners to unveil their new car, the W03, after opting to run their 2011-spec Merc during the first pre-season test in Jerez.
Word coming out of the paddock last week suggested they delayed the launch as they wanted to "hide a clever new front wing they have developed", but all will be revealed at 08.20 at the Circuit de Catalunya on Tuesday.
Michael Schumacher will be the first to drive the W03 as he will be on testing duty on days one and three with Nico Rosberg taking over on the Wednesday and Friday.
