Sergio Marchionne, Fiat's CEO who oversaw the creation of the merged Fiat Chrysler Automobile company, said that he plans to step down after completing a five-year strategic plan to expand the combined carmakers. "I am not going to do any more turnarounds. I'm done; let some of the young punks do it," said the 62-year-old marketer, who added that what he does now may require more than one person. "The role as presently configured will have to be reconfigured."
