Dave Pericak, current boss of Ford Performance, is leaving his position for Ford’s manufacturing division, where he’ll lead the engineering of the automaker’s unibody cars. Autosport reports that Pericak will leave Performance on December 1st and his roles will be filled by Mark Rushbrook on the motorsports side, and Hermann Salenbauch on the road car side.

Pericak has been an incredibly important figure at Ford

Pericak has been an incredibly important figure at Ford, essentially overseeing the creation of Ford Performance three years ago. During that time, Performance launched the wildly successful Focus RS, F-150 Raptor, Shelby GT350, and of course, the GT supercar. Pericak’s crowning achievement was arguably Ford’s 2016 class win at Le Mans with the GT.

“All the stuff we’ve been doing for the past three years has been pretty impressive, I think, personally, and I’m proud of it,” Pericak told Autosport. “Now, it’s time for me to go and take this global approach and bring it to the mainstream, where we can start affecting the way that we do production cars and trucks on a larger scale.”

Pericak will continue leading Ford’s World Endurance Championship and NASCAR efforts through the year too. Currently, Ford has a shot at the NASCAR title with Team Penske’s Brad Keselowski, who’s second place in points.
