Coming in lowest among the auto-related bosses is Uber CEO Travis Kalanick in the 44th spot. While his company doesn't build cars, it's certainly changing the way people get around cities. The ridesharing service's vehicles now reportedly outnumber traditional cabs in New York. However, the business is still fighting with governments around the world to continue growing.
In 23rd place is Elon Musk, who gets the accolade for his roles at both Tesla and SpaceX. Musk never seems to tire of starting new projects. Right now, his undertakings include construction of the Gigafactory and finally getting the Model X on sale. Plus, there's the issue of turning around Tesla's business in China.
Finally, General Motors CEO Mary Barra grabs ninth place to be the top automotive leader on Fortune's list, although she's already no stranger to the magazine's pages with accolades like the Most Powerful Woman in Business in 2014 and an editorial calling her "crisis manager of the year" for handling the ignition switch recall. Barra continues to receive praise here for handling the safety campaigns and dealing with investors.
