Nissan motorsport boss Darren Cox leaves company
Cox said: "The decision to leave Nissan was not an easy one.
"I have enjoyed a great many years working on some amazing projects with great people and have thrived on the challenges, successes and even failures in equal measure.
"I have seen GT Academy grow from a small European initiative to now embracing countries representing half the world's population."
It is understood that Cox was forced out after all his programs were failures – DeltaWing and ZEOD RC 'Garage 56' entries at the Le Mans 24 Hours in 2012 and '14, and then led the GT-R LM NISMO P1 program.
