Renault SA is considering selling part of its Nissan Motor Co. stake, a move that could raise billions of euros for its shift to electric vehicles and ease long-standing tensions with its alliance partner, people familiar with the matter said.

Nissan itself may be willing to buy some of the 1.83 billion shares in the Japanese automaker that Renault owns, according to the people, who asked not to be identified because the discussions aren’t public. Renault may also seek other buyers for a portion of its 43% stake in Nissan, the people said.

Spokespeople for Renault and Nissan declined to comment. Renault shares jumped as much as 8.3% as of Friday morning in Paris trading.
