Apparently the EVOS will be the design blue print for all future Ford designs. I can easily see the new Mustang adopting a shape very similar to this (just with a longer hood, and no hatchback). If so I'll be very excited as this car looks very Aston Martinish to me. Imagine a Mustang that looked like an Aston Martin!
You can see from the grille shape, that it is a modern stylized version of the current GT500 grille (except that the GT500 grille is divided into two parts). You can also see a tiny bit of hood overhang which is a Mustang trademark. My point is, it wouldn't be far-fetched to imagine this as the future of Mustang.
