The Request was based on the 1955 Four Hundred hardtop, but featured a classic upright Packard fluted grille reminiscent of the prewar models. In addition, the 1957 engineering mule "Black Bess" was built to test new features for a future car. This car had a resemblance to the 1958 Edsel. It featured Packard's return to a vertical grill. This grill was very narrow with the familiar ox-yoke shape that was characteristic for Packard, and with front fenders with dual headlights resembling Chrysler products from that era. The engineering mule Black Bess was destroyed by the company shortly after the Packard plant was shuttered. Of the 10 Requests built, only four were sold off the showroom floor.
