See, rumors of a 'Cuda or Barracuda revival have circulated pretty much since the moment Dodge showed the modern Challenger and when it went on sale. And some of those rumors have involved the re-registering of the 'Cuda trademark, even as far back as 2010. Over the years, each rumor died a quiet death as time went on and no 'Cudas appeared on dealer lots.
There is one rumor that's recent enough to still have a slim chance of realization, circa 2015 to be exact. It predicts a smaller Challenger-based car called Barracuda that could appear as a Dodge in both coupe and drop-top versions. However, we doubt it will come true, since FCA doesn't exactly have a large development budget, and we're not sure what the company would have to gain by making another sports car to sell below the Challenger. Odds are, it would cannibalize sales from the older, completely developed, and thus more profitable Challenger.
Really, this trademark filing is probably just a defensive move for Chrysler. It will ensure that no one else can slip in and snag the name for their own vehicle. It should also help ensure that Chrysler has the rights to use the name on other products such as memorabilia. Sorry to crush your dreams.
