McLaren has undertaken a reshuffling of its aerodynamic department as part of an ongoing review of its Formula 1 operations.
AUTOSPORT has learned that head of aerodynamics Marcin Budkowski has left the team.
As a result, chief aerodynamicist Doug McKiernan will now head the Woking-based outfit'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.
When contacted by AUTOSPORT, a McLaren spokesman confirmed Budkowski's departure and said that the parting of ways had been mutual following a disagreement about future direction.
"Marcin and McLaren Racing have differing views on the strategic plans affecting the aerodynamics department and as such we have agreed to part company," the McLaren spokesman explained.
"We wish Marcin all the best for his future after six years and thank him for his valuable contribution during that time."
The reshuffling of roles in the aerodynamics departments comes on the back of a thorough review of the racing team by new group CEO Ron Dennis.
Since Dennis reclaimed control, the team has appointed Eric Boullier as its new racing director and managing director Jonathan Neale as the team's stand-in CEO
