25 most powerful people in business

Some are empire builders. Others are hired guns. But if they truly have world-class oomph, they're on Fortune's subjective - yet really quite accurate - list of the most powerful businesspeople in the world.

Katsuaki Watanabe
9. Katsuaki Watanabe
President, Toyota

No question: When Katsuaki Watanabe became president of the world's most admired company in 2005, he took the wheel of a well-oiled machine. But he is making his own mark on it, urging the company, which earned $14.1 billion last year, to keep getting better. He launched a quality-improvement campaign that helped make the debut of the 2008 Highlander SUV just about trouble-free and has the company on track to overtake General Motors for good as the world's largest automaker. His ultimate goal: a car that can drive across the U.S. on a single tank of gas. At the speed he has Toyota moving, you can pencil that in for 2050. --Alex Taylor III
