Playboy has always had its share of heart-pounding excitement. But some of the newest models making men's pulses race don't list numbers like 35-23-35 on their data sheets. Their prime stats are all about horsepower and straightaway speed.

The rabbit-head logo is now making its mark on the racing world thanks to the new Playboy Racing Team, a world-class partnership including Tommy Constantine Racing and sponsors Uniden Electronics, The Palms Resort & Casino and Vonage. Beginning this season, six cars will circle the nation's speedways for Playboy, competing in the Grand American Rolex Sports Car Series presented by Crown Royal Special Reserve and the Grand-Am Cup Series. At every stop on the tour, you can see the team vie for a spot on the podium and meet Playboy Playmates at special After Race VIP events. The only problem is figuring out which models to focus on.
