An early mover in the electric car race, Renault has fallen behind newer, more agile rivals like Tesla.
But big question marks remain on its strained relationship with long-standing Japanese partner Nissan, as Renault looks for other outside investors for each of its divisions.
Nissan (7201.T) is expected to take a stake in the EV venture, codenamed "Ampere", alongside other investors, though Renault will keep a majority stake.
Renault CEO Luca De Meo said the group wanted to give the alliance a strong future and a "new chance".
Aside from the Ampere EV unit and the combustion engine division, Renault will have an additional three businesses - the Alpine sports-car brand, financial services and new mobility and recycling activities.
