In any case, it is true that Packard fell behind its rival, Cadillac, in sales. This trend was not helped by Packard's unfortunate 1948 facelift that I touched on here.
A total redesign marked the 1951 model year. As I note in my ebook "How Cars Faced the Market," Packard was one of those companies that favored strong, consistent styling cues that visually proclaimed the brand. Packard used red hexagons on its hubcaps, a pen-nib spear side trim, and what many observers term a "yoke" grille. The latter feature worked well when cars were tall and hoods were narrow. But the '51 Packards followed industry design trends and were comparatively low and wide. Plus, American styling fashions in the late 1940s and early 50s called for large, chromed grille elements. So Packard stylists had to come up with grille designs that were low, wide and bold, yet carried on shape elements from previous Packards.
