Carlos Ghosn plans to immerse himself in Renault matters when he succeeds Louis Schweitzer as CEO next year.
Many wonder how Ghosn, for all his famed personal energy, will manage to run both the French automaker and its Tokyo-based ally Nissan.
Ghosn originally moved to Japan in 1999 when Schweitzer named him the head of Nissan, which is 44 percent owned by Renault. Ghosn's task was to turn the company around.
Having fulfilled his mission, Ghosn is slated to replace Schweitzer after the annual shareholders meeting in May.
"I have been breathing, living and sleeping Nissan for the last five years," Ghosn said in Paris. "I shall have to rediscover Renault and its people."
So he will spend most of his time next year with Renault. After that, he will split his time evenly between the two companies.
Ghosn ruled out quitting the Renault-Nissan group. "I am not looking for another challenge elsewhere," he said. "You don't get bored in that industry."
Meanwhile, Schweitzer will remain as Renault's nonexecutive chairman, a role he will also take at AstraZeneca, an anglo-Swedish pharmaceutical company.
