Mercedes holds Twitter race for Super Bowl

Mercedes-Benz, which is advertising on the Super Bowl this year, is hoping to drive engagement with something called the “Tweet Race to the Big Game.” Beginning four days before the Feb. 6 game, four racing teams led by four celebrities (Serena Williams, Rev Run, Nick Swisher and Pete Wentz) will make their way to Cowboys Stadium outside Dallas from Chicago, New York, Los Angeles and Tampa in specially equipped Mercedes vehicles, competing in a series of challenges along the way.
