Cyril Abiteboul: "Renault and McLaren have different ambitions"

McLaren and Renault came together at the start of 2018, after McLaren suffered three horrific years with Honda, with the French team powering McLaren the sixth in the championship in their first season as partners.

This season has been even better for McLaren, who currently sit fourth in the constructors' standings, ahead of Renault.

Renault boss Abiteboul said: "Since our partnership began, McLaren has gone from ninth to fourth position in the Constructors’ Championship. We can therefore consider this a very successful relationship. However, while looking beyond the terms of the current contract, which concludes at the end of 2020, it was apparent that Renault and McLaren have different ambitions for the future.

"Each of the different elements of this decision have been carefully evaluated over the past few weeks. 2021 will be a crucial season for all teams and it is important for us to have a precise and clear view of the strengths and ambitions of our competitors going forward.

"This decision is in line with Renault’s vision to become a works’ team, with a goal to return to the front.

"Renault will continue to honour its commitments to McLaren Racing next season, as has always been the case over our long history of engine supply."
