Reports in the British press suggest McLaren could name Sam Michael as their new team boss at Friday's launch.
With Ron Dennis taking the reigns at McLaren earlier this month, sweeping changes are expected at the Formula One team.
One of those changes could be the exit of Martin Whitmarsh.
The current team boss is under fire after a dismal 2013 season for McLaren in which the team failed to secure a single podium finish.
And, according to Telegraph Sport could be on his way out.
In a press release earlier this week announcing Stoffel Vandoorne as the team's official reserve driver, instead of putting in quotes from Whitmarsh, McLaren quoted Michael.
This, the newspaper speculates, could be a "small indication" that Whitmarsh is on his way out and Michael is set for promotion.
