Ford Mustang GT-R Concept:

Officially the Mustang GT-R is a concept car, but it was developed and built by Saleen Specialty Vehicles in Troy, Michigan, to be capable of competing as a racecar. It also aims to show grass-roots racers that they can take a stock Mustang (85 percent of the GT-R's body structure is unchanged), and build a competitive vehicle at a reasonable price using parts from the Ford Racing catalogue, like the 440-hp 5.0-liter "Cammer" crate engine that retails for $14,995 and can be tuned to over 500 hp. That power is routed through a Ford Racing TTC-T56 six-speed transmission, a custom metal matrix composite aluminum driveshaft, and into a race-spec 4.56:1 differential. Big Brembo brakes, 20-inch Pirelli racing slicks, and competition suspension (retaining the live rear axle) round out the package. Carbon fiber is used for the hood, grille surround, and underbody belly pan, and the orange paint is meant to evoke the Grabber Orange 1970 Mustang Boss 302 Trans-Am racecars.
