MARANELLO, Italy (AP) Ferrari's technical director James Allison has left the team in what was described as a joint decision following a disappointing first half of the Formula One season during which Ferrari failed to win a race.
Allison spent three years in his second stint with Ferrari. Team chief Maurizio Arrivabene thanked him for his ''commitment and sacrifice'' and wished him ''success and serenity for his future endeavors.''
Mattia Binotto takes over as chief technical officer, only days before Sunday's German Grand Prix.
Allison was at Ferrari as head of aerodynamics during the dominant Michael Schumacher era of 2000 to 2004, before moving back to the Renault team, where he was deputy technical director when Fernando Alonso won consecutive titles in 2005 and 2006.
