Audi has stayed quiet about its Sport Quattro Concept since the 700-horsepower, tangerine rocket debuted at the 2013 Frankfurt Motor Show – a followup to Quattro Concept shown at the 2010 Paris Motor Show. Now, Audi has broken the plug-in hybrid out to give thanks to its Facebook fans, which now number over 100,000 strong (103,123 as of this writing).
Kia has 2.1 million fans on Facebook, though we'd wager that far more people worldwide own Kias than are fans of the Korean automaker's page. On the other hand, Ferrari, whose owners number just a lucky few, has a legion of fans counted in the millions. In fact, the Facebook page for the Italian automaker just surpassed 10 million Likes.
