McLaren has undertaken a reshuffling of its aerodynamic department as part of an ongoing review of its Formula 1 operations.
Head of aerodynamics Marcin Budkowski has left the team. Chief aerodynamicist Doug McKiernan will now head the squad's aerodynamic operations ahead of the start of the 2014 season.
Budkowski originally joined McLaren in 2007 as a senior aerodynamicist, moving up the ranks to become head of aerodynamics from November 2012. He played a key role in last year's MP4-28.
A McLaren spokesman confirmed Budkowski's departure and said that the parting of ways had been mutual following a disagreement about future direction.
