The Mustang is not a muscle car. I'll repeat it is not a muscle car. It is a pony car. There is a difference.
That said people keep saying the renderings are not "true American", or some shit, designs. Someone please define what makes a design "true American".
You do have a good point....never really heard the term pony car before. from Wikipedia so take it for what it's worth:
Stylish and sporty styling that included "long hoods, short decks, and open mouths"
Assembled from "off-the-shelf" mass production components
Affordable base price (under $2,500 — in 1965 dollar value)
Wide range of options to individualize each car
Youth-oriented marketing and advertising.
While most of the pony cars offered more powerful engines and performance packages, enough to qualify some into muscle car territory, a substantial number were sold with six-cylinder engines or ordinary V8s.[14] For the most part, the high-performance models saw limited sales and were largely limited to drag racing, road racing, or racing homologation purposes.

Nothing sweet about a mustang looking like a GTO "Ever!!"
