Limited to Mustangs equipped with the turbocharged 2.3-liter inline-four EcoBoost engine—sorry, V-8 fans—the Pony package includes a handful of throwback styling items such as a grille that features a chrome surround around the iconic galloping horse; stripes on the lower body sides; and a red, white, and blue tri-bar Mustang badge on the rear decklid. The Pony package also brings 19-inch polished aluminum wheels and package-specific floor mats, while coupes add chrome trim along the window line.
