45. Sergio Marchionne
CEO, Fiat; CEO, Chrysler

Marchionne was asked to turn around Chrysler after Italian automaker Fiat bought a 20% interest in the fallen American brand last summer. The Fiat chief quickly obliterated the old Chrysler management structure and vowed to bring new models faster to market. The result: a new Dodge Charger, an updated Jeep Wrangler Unlimited, and a three-row crossover vehicle. But Marchionne has even more riding on the upcoming U.S. release of the Fiat 500, a subcompact that can get 56 miles per gallon.
