Renault has announced Formula 1 boss Cyril Abiteboul will leave the French manufacturer with immediate effect before it morphs into Alpine for the 2021 season.

Despite a major management shake-up, Abiteboul was expected to stay on in a different role, but will be leaving the Renault operation entirely.

The Frenchman’s departure sees Laurent Rossi, who previously worked as Renault’s director of strategy and business development, appointed as Apline’s CEO.

Rossi will be in charge of the Alpine’s car division, alongside its F1 project and other motorsport activities, and will report to Renault’s CEO Luca de Meo.

It has been widely reported that Abiteboul’s position as team principal will be filled by Marcin Budkowski.

Abiteobul, who was pivotal in Renault’s deicison to return to F1 in 2016, said: “I would like to thank the Groupe Renault for having trusted me for many years, particularly with the relaunch and reconstruction of the team since 2016.

“The solid foundations of the racing team and the entities in France and England built over these years, the strategic evolution of the sport towards a more economically sustainable model, and more recently the Alpine project which provides a renewed sense of meaning and dynamism, all point to a very fine trajectory.”

De Meo added: “I would like to warmly thank Cyril for his tireless involvement, which notably led the Renault F1 Team from the penultimate place in 2016 to the podiums last season.

“His remarkable work in F1 since 2007 allows us to look to the future, with a strong team and the new Alpine F1 Team identity to conquer the podiums this year.”

Abiteboul joined Renault after university before graduating to the F1 team in 2007, becoming executive director three years later.

He would later join Caterham in 2012 and soon take on the role as team principal, but left in 2014 prior to the team’s demise.

Returning to Renault’s engine division as managing director, Abiteboul would help oversee the French manufacturer’s takeover of Lotus to bring the Renault name back to the F1 grid.
