Carlos Ghosn often is asked how long he's going to remain chairman and CEO of both Renault and Nissan.
No answer yet, but one thing is certain: He doesn't recommend the arrangement for his successor.
"I don't think it should continue," Ghosn said of the arrangement during a recent interview. "I know how hard it is. It takes a lot of energy, organization. It is a lot of frustration. I don't think it is worth it unless you can see it clearly makes sense."
Ghosn, 57, has had experience running both brands in various roles -- from advanced research to powertrain and purchasing.
He said he became the boss of both automakers because he could legitimately represent both sides.
"But I don't think I can find a successor who could do both jobs," he said. "If it is by choice, it is better to be CEO of one company. It is less complicated, less conflictual, and you are not being accused of being here when you need to be there."
