In a Press release just moments ago Caterham F1 announced Cyril Abiteboul as their new CEO, with responsibility for the teams on and off track operations. He's third in line to the overall Caterham Group CEO Riad Asmat and obviously Tony Fernandes.
However, given that he's currently working as Deputy Managing Director of Renault Sport F1, and is to split his word between the two until January next year, it remains to be seen how the other teams using the Renault engine will feel about this dual role.
I would particularly wonder how Red Bull will feel given their sister cars, the Toro Rosso's are the yardstick to which the Caterham F1 team are measuring themselves at the minute.
The full press release is available on the Caterham page in the Right-hand sidebar.
