Sex sells in 2013 Super Bowl ads

Super Bowl car ads are big business. To create even more of a buzz, many automakers pre-release commercials on YouTube in the days leading up to the big game.

So far Audi, Volkswagen, Fiat, Hyundai and Mercedes-Benz have released ads. As you may have guessed, Mercedes' ad -- featuring model and actress Kate Upton approaching in slow motion as a team of young football players washes her car -- has collected more than 5 million views. The Toyota RAV4 ad and Audi S6 spot are doing well too, each earning more than 1 million views so far.
