Nissan Examines Possibility of Breaking Away From Renault

Nissan Motor Co. executives have examined the possibility of breaking away from Renault SA amid concerns that relations with the longtime French partner have turned dysfunctional after the ouster of former chief Carlos Ghosn, according to a person familiar with the matter.

Since last year, Nissan has been exploring the pros and cons of sustaining the alliance, particularly when it comes to engineering and technology sharing, according to the person, who asked not to be identified discussing confidential matters. Those studies predate Ghosn’s escape from Japan and were preliminary, so no decision has been made, the person said.
