2013 Ford Mustang Shelby GT500 to pump out 662hp and 630 lb-ft of torque, but still gets 24 mpg on the highway.

This looks, my my eyes, to be a 1969 mustang - a fairly rare GT Coupe. See, the GT packages were about the same cost as the Mach 1 packages that came out that same year. The Mach 1 had some styling and handling upgrades that the GT didn't have. That's just my guess.
