Mary Barra Tops Fortune’s Most Powerful Women List as GM CEO 

On January 15, 2014, Mary Barra stepped into the role of CEO at General Motors. Since then, she has shaped the company’s direction across markets far and wide. By January 4, 2016, another title joined hers – Chair of the Board. Her influence didn’t peak early – it built steadily, year after year. Then came May 2025: Fortune placed her first among women shaping business worldwide. Not just a name on a list, but standing ahead of all others in an industry long dominated by men. Leadership like that doesn’t shout. It simply stays, season after season, where few have lasted. 

Now leading General Motors, Barra reshaped it into a major player in electric cars and tech. Because of her direction, huge sums went toward building EVs, self-driving systems via Cruise, along with smart vehicle software. With each move carefully weighed, the automaker stands ready to challenge Tesla and early green-car leaders without losing its roots in mainstream auto manufacturing. 

Breaking barriers, Barra became the first female CEO of a top global car company. Not just a milestone at GM, her presence shifts norms across factories and boardrooms alike. Through steady voice, she pushes training programs, cleaner production methods, fairer hiring. Innovation under her watch leans into electric vehicles without losing sight of real customer needs. What sticks is how quietly she redefined what big automakers dare to become. 

Out front, Fortune spots what Barra’s done – growth hums louder under her watch. Through rocky markets, tangled logistics, sudden turns in auto trends, she holds steady – GM stays planted where it counts. Not every leader weathers that mix without losing grip. Women shaping factories, steering car giants, running big teams – they see themselves in how she moves. Strength shows up quiet sometimes. Hers leaves marks.
