What you see lines up with what we learned shaking various trees almost a year ago. All the 50th anniversary Mustangs are white, and they're all GTs with the 5.0 Coyote V8. In an obvious nod to Mustang heritage, the grille gets a retro treatment, with the boxed pony and blades that extend laterally from it. In addition, this prototype's rear quarter windows are disguised, lending credence to the idea that the anniversary cars will sport louvered covers there,*a la*the original fastbacks.*Also new: this car's wheel design. Unfortunately, we didn't get a look at the interior...yet.
