Certainly, Scottsdale's Danica Patrick, the only woman seriously competing in professional motor sports these days, is the best-looking human in racing. (Ever get a look at Dale Earnhardt Jr.?) We'd only seen her beautiful head emerging from those emblem-cluttered racing coveralls until we spotted her at a Diamondbacks game, and we've got to tell you, she's all-over hot. (Down, boys! She's married.) Once she started driving in the Indianapolis 500, Playboy asked her to pose nude for the magazine, an offer she turned down. She did make the cover of Sports Illustrated in 2005, however, but it was because she was the fourth woman ever to compete in the Indianapolis 500 — and named the event's rookie of the year — not because (too bad!) she rocked a skimpy swimsuit. Yeah, we know, we're drooling over her sexiness. But this hottie can handle a powerful engine like no woman in history. (Hey, we resisted using a drive-shaft metaphor.) Her third-place finish in the Indy 500 was the best by a chick in the race's history. Danica became the first woman to win an Indy race in 2008 with her victory in the Indy Japan 300. This year, she's driving a Chevy for Scottsdale's GoDaddy.com in NASCAR's Nationwide Series. Go, mama!
