McLaren has tweaked its schedule for the final test of the 2011 pre-season.
Like the other eleven teams, the British outfit had planned to run on four consecutive days of the five-day schedule between Tuesday and Saturday.
The Dutch website f1today.nl reports that McLaren will actually run between Tuesday and Saturday in Barcelona, sitting out Thursday's play.
The session will therefore be split into two parts by McLaren; Tuesday-Wednesday, and Friday-Saturday. The Woking based team has been contacted for confirmation.
The Circuit de Catalunya test will in fact total six days overall, after Ferrari kicked off its own programme with a filming day on Monday.
And it was rumoured that Red Bull might copy McLaren's two-session idea by also sitting out Thursday.
But "(our schedule) remains Tuesday to Friday," a team spokeswoman clarified to Germany's Auto Motor und Sport.
