Sebastian Vettel

Known personal vehicles: Infiniti FX50

At 23, German Formula One world champion Sebastian Vettel is the youngest driver to earn the title. His driving associates include Julia and Kate, Kate’s Dirty Sister, Luscious Liz, Randy Mandy, and Kinky Kylie—all names of his cars.

Off-track, Vettel says he loves driving so much that he’ll drive anything. He told The Times, “I drive the cars that I like — I’m not a car snob. So if I like a Skoda, then I drive a Skoda. But actually I am ambassador for BMW, so I drive BMWs.” On a perhaps related note, Vettel drives an Infiniti FX50 as his personal vehicle, and Infiniti has a partnership with Sebastian’s Red Bull Racing Team.
