Stefano Domenicali has been with Ferrari for 23 years and been the Team Principal since 2008. Ferrari hasn't won a championship while he's been at the helm and has been having an abysmal 2014. Now Domenicali has "resigned" and it definitely wasn't forced on him. No sir.
Ferrari's official announcement is that Domenicali resigned in order to "shake things up" and that this was a "difficult and very painful decision." It was painful because it was difficult, definitely not because Luca Di Montezemolo had applied so much pressure to Domenicali that he was about to break in half.
This is normal for F1. If a team is underperforming, especially one with the reputation of Ferrari, the team principal has to leave. Domenicali really had no choice.
Di Montezemolo said "I thank Stefano Domenicali, not only for his constant dedication and effort, but also for the great sense of responsibility he has shown, even today, in always putting the interests of Ferrari above all else." Remember, this was totally Domenicali's own choice and had nothing to do with Di Montezemolo and his rumored puppet master ways behind the scenes.
Domenicali will be replaced by Marco Mattiacci, who is the current head of Ferrari North America. It takes effect immediately at the Chinese Grand Prix.
And in other F1 news, Mercedes AMG technical director Bob Bell will be stepping away from his post at the end of the 2014 season to "pursue opportunities outside the team." He reportedly told them in late 2013. I'd bet he might end up back at McLaren, his old stomping ground.
