The iconic Mustang celebrated half a century on the road in 2014, when Ford and numerous fan clubs organized a series of events throughout April, the month the first-generation pony-car made its debut back in 1964. A full year has passed since then, and Ford is once again celebrating as the nameplate turns 51. This time around there aren’t any "Mustangs Across America" drives, though. Instead, FoMoCo is releasing a special movies series on how the latest Mustang came to be. The first chapter is about the sixth-gen model’s design, which still is the subject of controversy among Mustang enthusiasts.
