Renault reshuffle after Red Bull team says engines are 'unacceptable'
{{#rendered}} {{/rendered}}The Renault engine supply team that powered Sebastian Vettel to four successive Formula One championships announced a major reshuffle on Thursday after mounting criticism from Red Bull.
The most dramatic move saw Renault Sport F1 president and managing director Jean-Michel Jalinier resign and retire.
He was replaced by Jerome Stoll, who becomes president, and former Caterham team principal Cyril Abiteboul, who will be managing director.
