Ford is offering a comprehensive lineup for the S650 Mustang with a plethora of street-legal models and race cars. The pony car with a license plate can be had in EcoBoost, GT, and Dark Horse flavors whereas its track-only sibling is getting no fewer than six iterations. Depending on the specification, these will compete in GT3, GT4, NASCAR, and NHRA Factory X. Then there’s the Dark Horse S "for the weekend track day enthusiast" and this, the Dark Horse R.
