The Ford Mustang RSX is a concept car that was built by Ghia, for Ford in 1980. The initials of the Mustang RSX stood for Rallye Sport Experimental. This two-seat sport coupe was designed by Ford’s Ghia studio in Turin, Italy. Finished in metallic orange, the body featured simulated all glass doors and a rear airfoil was used to improve directional stability and lessen wind resistance. With a wheelbase nearly 6-inches shorter than the production Mustang, the lighter RSX was powered by a 2.3-litre four-cylinder engine that was teamed with a four-speed manual gearbox.
