Renault will carry out a plan to carve out electric and combustion-engine businesses, even without its Japanese auto-making partners.
"They know that we have to do it, that we will do it and we have opened the door for them to each project," Renault CEO Officer Luca de Meo said.
"At the end it's their decision if they want to jump in the boat, but the train is leaving the station," de Meo said.
De Meo's plan to split the automaker's operations is gaining traction after talks with French unions got underway and discussions also started with top management of its alliance partners Nissan and Mitsubishi Motors.
De Meo has said he will disclose details of the transformative plan in the fall after "transparent" discussions with the Japanese companies.
