Nissan Motor Co. is considering plans to restructure its alliance with Renault SA, including ending the French manufacturer's voting rights, according to sources.

A paper circulated to Renault board members by Nissan Chief Competitive Officer Hiroto Saikawa laid out a scenario that could grant the Japanese company voting rights in Renault, reversing the French carmaker's one-sided control of the partnership, said the sources, who asked not to be identified because the discussions are private.

The document is part of a broader process to restructure the 16-year-old alliance, and no decisions are anticipated immediately, the sources said.
